Overview



We are a commercial-stage biopharmaceutical company focused on the development
and commercialization of novel small molecule therapeutics for the treatment of
patients with cancer. Our first product approved by the U.S. Food and Drug
Administration ("FDA"), COSELA™ (trilaciclib), is the first and only therapy
indicated to proactively help protect bone marrow from the damage of
chemotherapy (myeloprotection) and is the first innovation in managing
myeloprotection in decades. Trilaciclib was developed from a technology platform
that targets key cellular pathways including transient arrest of the cell cycle
at the G1 phase, prior to the beginning of DNA replication. Controlled
administration and clean G1 arrest reduce hematologic adverse events ("AEs")
caused by cytotoxic therapy and may increase the ability to receive longer
treatment durations. Transient CDK4/6 inhibition also modulates multiple immune
functions while allowing beneficial T cell proliferation which may improve
patients' anti-tumor immune responses. We are exploring the use of trilaciclib
in a variety of trials across multiple tumor types and treatment combinations to
optimize these dual benefits of myeloprotection and improved anti-tumor efficacy
for patients globally.

We shall use "COSELA" when referring to our FDA approved drug and "trilaciclib" when referring to our development of COSELA for additional indications.

COSELA is a prescription medicine used to help reduce the occurrence of low blood cell counts caused by damage to bone marrow from chemotherapy. COSELA is used to treat adults taking certain chemotherapies (platinum/etoposide or topotecan) for extensive-stage small cell lung cancer.

COSELA is an injection for intravenous (IV) use given within 4 hours before chemotherapy.






Commercial Product

[[Image Removed]]



On February 12, 2021, COSELA (trilaciclib) for injection was approved by the FDA
to decrease the incidence of chemotherapy-induced myelosuppression in adult
patients treated with a platinum/etoposide-containing regimen or
topotecan-containing regimen for ES-SCLC. COSELA became commercially available
through our specialty distributor network on March 2, 2021.

We announced on March 25, 2021 that COSELA had been included in two updated
National Comprehensive Cancer Network® ("NCCN") Clinical Practice Guidelines in
Oncology (NCCN Guidelines®): The Treatment Guidelines for Small Cell Lung Cancer
and the Supportive Care Guidelines for Hematopoietic Growth Factors. These
guidelines document evidence-based, consensus-driven management to ensure that
all patients receive preventive, diagnostic, treatment, and supportive services
that are most likely to lead to optimal outcomes. On October 1, 2021, we
announced that the permanent J-code for COSELA that was issued in July 2021 by
the Centers for Medicare & Medicaid Services (CMS) is now effective for provider
billing for all sites of care. All hospital outpatient departments, ambulatory
surgery centers and physician offices in the United States have one consistent
Healthcare Common Procedure Coding System (HCPCS) code to standardize the
submission and payment of COSELA insurance claims across Medicare, Medicare
Advantage, Medicaid and commercial plans. Our new technology add-on payment
(NTAP) for COSELA which provides additional payment to inpatient hospitals above
the standard Medicare Severity Diagnosis-Related Group (MS-DRG) payment amount
also became effective for provider billing on October 1, 2021.

We are also exploring potential use of trilaciclib in a variety of tumors,
including colorectal cancer ("CRC"), breast cancer, bladder cancer, and in
trials designed to inform the design of future additional pivotal studies across
multiple tumor types and treatment combinations including targeted chemotherapy
medicines called antibody-drug conjugates (ADCs).

                                       22
--------------------------------------------------------------------------------



In June 2020, we entered into a three-year co-promotion agreement for COSELA in
the United States and Puerto Rico with Boehringer Ingelheim Pharmaceuticals,
Inc. In December 2021, the Company and Boehringer Ingelheim mutually agreed to
end the co-promotion agreement for COSELA, effective March 2022. At that time,
we announced that we would hire and deploy a total of 34 oncology sales
representatives to allow us to target all accounts to accelerate sales
activities and help maximize the adoption of COSELA. As of February 21, 2022,
all 34 sales representatives have been hired, trained, and deployed into their
respective regions.


Product Portfolio

Trilaciclib is a first-in-class therapy designed to help protect against
chemotherapy-induced myelosuppression. Trilaciclib, a novel transient IV CDK4/6
inhibitor has unique attributes including rapid onset from IV administration,
potent and selective CDK4 and CDK6 inhibition and a short half-life. Controlled
administration and clean G1-phase arrest reduce hematologic AEs caused by
cytotoxic therapy and may increase patients' abilities to receive longer
treatment durations. Transient CDK4/6 inhibition also modulates multiple immune
functions while allowing beneficial T cell proliferation which may improve
patients' anti-tumor immune responses.

Trilaciclib transiently blocks progression through the cell cycle. This provides
benefits which manifest depending on the tumor type and therapeutic backbone,
including: (1) proactive multi-lineage myeloprotection, and (2) potentially
improved anti-tumor efficacy.

First, trilaciclib provides proactive multi-lineage myeloprotection by
transiently arresting hematopoietic stem and progenitor cells ("HSPCs"), helping
to protect them from damage caused by cytotoxic therapy thereby minimizing
cytopenias across neutrophils, erythrocytes, and platelets. These proactive
multi-lineage myeloprotection benefits were seen in our three double-blind,
placebo-controlled clinical trials in ES-SCLC, where highly myelosuppressive
chemotherapy regimens are administered multiple days in a row. This
myeloprotection benefit is being explored as the primary endpoint in our ongoing
PRESERVE 1 trial in 1L colorectal cancer.

Second, trilaciclib may have the ability to improve anti-tumor efficacy through
a combination of potential factors, including increasing patients' ability to
receive more cytotoxic therapy, protecting the immune system from damage caused
by cytotoxic therapy, and favorably modulating multiple immune functions while
also allowing beneficial T cell proliferation. In particular, these immune
function improvements may include: (1) enhancing T cell activation (via
increased antigen presentation and secretion of IL-2 and IFN?), (2) favorably
altering the tumor microenvironment (via increased chemokines responsible for
trafficking T cells to tumors and reducing the number and function of
immunosuppressive cell populations), and (3) improving long-term immune
surveillance (via increased generation of memory CD8+ T cells). A meaningful
anti-tumor efficacy benefit was observed in our Phase 2 mTNBC study in which
trilaciclib led to a significant improvement in overall survival when
administered in combination with chemotherapy compared to chemotherapy alone. We
are exploring these dual benefits of myeloprotection and anti-tumor efficacy
across a variety of ongoing Phase 2 and Phase 3 clinical trials.

We are executing on our tumor-agnostic strategy to evaluate the potential
benefits of trilaciclib to patients with other tumors to continuously develop
new data with trilaciclib in a variety of chemotherapeutic settings and in
combination with other agents to maximize the applicability of the drug to
potential future treatment paradigms. We currently have five ongoing clinical
trials: a pivotal Phase 3 trial in 1L colorectal cancer ("CRC"), a pivotal Phase
3 trial in 1L mTNBC, a Phase 2 trial in 1L bladder cancer with chemotherapy
induction and a checkpoint inhibitor maintenance, a Phase 2 trial in combination
with an antibody-drug conjugate ("ADC") in 2L/3L mTNBC, and a Phase 2 trial in
neoadjuvant TNBC designed to validate trilaciclib's immune-based mechanism of
action ("MOA"). These studies across treatment settings and tumor types will
evaluate trilaciclib's dual benefits of proactive multi-lineage myeloprotection
and anti-tumor efficacy across tumor types. In addition, the MOA and ADC trials
will inform the design of future additional pivotal studies across multiple
tumor types and treatment combinations. We are also conducting significant
preclinical work to assess the additive/synergistic potential of trilaciclib
with a variety of novel and emerging therapeutic agents to identify synergies to
evaluate in future clinical trials. Our clinical approach to designing our
clinical program includes monitoring the evolution of future standards of care
and develop trilaciclib with these in mind, allowing us to conduct or support
trials that will generate important data to maximize future usage in a variety
of future settings.

Lerociclib



Lerociclib is a differentiated clinical-stage oral CDK4/6 inhibitor being
developed for use in combination with other targeted therapies in multiple
oncology indications. In 2020, we entered into separate, exclusive agreements
with EQRx, Inc. (rights for U.S., Europe, Japan and all markets outside
Asia-Pacific) and Genor Biopharma Co. Inc. (rights for Asia-Pacific, excluding
Japan) for the development and commercialization of lerociclib in all
indications. Combined, these agreements provide $26.0 million in upfront
payments, along with sales-based royalties, and the opportunity for up to $330.0
million in potential milestone payments. EQRx, Inc. and Genor Biopharma Co. Inc.
are responsible for all costs related to the development and commercialization
of lerociclib in their respective territories.

Rintodestrant



Rintodestrant is an oral SERD, for use as a monotherapy and in combination with
CDK4/6 inhibitors, initially Ibrance® (palbociclib), for the treatment of ER+,
HER2- breast cancer. After completing the evaluation of our rintodestrant
partnering options and recent data in the highly competitive oral SERD space, we
have made the strategic decision to discontinue the program, including all
clinical and partnering efforts. We will responsibly wind down all remaining
clinical efforts for rintodestrant by the end of this year and revert the rights
back to the originator (University of Illinois Chicago); there are no additional
financial obligations due to the originator resulting from the reversion.



                                       24
--------------------------------------------------------------------------------

CDK2 Inhibitor



In 2020, we entered into a global license agreement with Incyclix Bio, LLC
("Incyclix"), formerly ARC Therapeutics, LLC, for the development and
commercialization of an internally discovered cyclin dependent kinase 2 ("CDK2")
inhibitor for all human and veterinary uses. Incyclix is currently granted an
exclusive, royalty-bearing, license with the right to grant sublicenses to one
of our solely owned patent families.


Coronavirus (COVID-19) impact on operations



We have implemented business continuity plans to address the COVID-19 pandemic
and minimize disruptions to ongoing operations. Enrollment of patients in
current and future clinical trials may be impacted by COVID-19. Although we have
not had any significant supply chain delays or shortages as a result of the
COVID-19 pandemic to date, we have experienced delays in the delivery of our
investigational product to certain investigative sites due to shortages of
ancillary materials and the delay of governmental inspections. To date, we are
on track to meet all of our previously announced clinical milestones. If the
COVID-19 pandemic continues or increases in severity, we could experience
disruptions to our clinical development timelines. If we experience delays in
patient enrollment, we could incur increased clinical program expense if it is
deemed necessary or advisable to improve patient recruitment by opening
additional clinical sites. COVID-19 travel limitations and government-mandated
work-from-home or shelter-in-place orders may reduce the number of in-person
meetings with prescribers and fewer patient visits with physicians, potentially
resulting in fewer new prescriptions.

We established a COVID-19 response team which continually monitors the impact of
COVID-19 on our operations. The COVID-19 response team manages our workplace
protocols that govern our employees' use of our office. To mitigate the impact
of COVID-19 on our business, we put in place the following safety measures for
our employees, patients, healthcare professionals, and suppliers to limit
exposure: we substantially restricted travel, supplied personal protective
equipment to employees, limited access to our headquarters and asked most of our
staff to work remotely. As of March 31, 2022, the majority of our employees are
still working remotely, which may negatively impact our ability to conduct
research and development activities, engage in sales-related initiatives, or
efficiently conduct day-to-day operations. In addition, we added bandwidth and
VPN capacity to our infrastructure to facilitate remote work arrangements. We
will continue to monitor the impact of COVID-19 on our operations, including how
it will impact our employees, clinical trials, development programs, supply
chain, and other aspects of our operations, and report to our Board of Directors
regularly on the progress of our response to the COVID-19 outbreak.

Financial Overview



Since our inception in 2008, we have devoted substantially all of our resources
to synthesizing, acquiring, testing and developing our product candidates,
including conducting preclinical studies and clinical trials and providing
selling, general and administrative support for these operations as well as
securing intellectual property protection for our products. Currently, COSELA is
our only product approved for sale. We began generating revenue for the net
product sales from COSELA in March of 2021. We recorded $5.5 million and $11.1
million of net product sales from COSELA for the three months ended March 31,
2022, and the year ended December 31, 2021, respectively. We recorded $1.4
million and $20.4 million of license revenue for the three months ended March
31, 2022, and the year ended December 31, 2021, respectively. To date, we have
financed our operations primarily through the sale of equity securities, our
loan agreement with Hercules Capital, Inc., and licensing arrangements. Under
our licensing arrangements, we are eligible to receive certain development and
sales-based milestones. Our ability to earn these milestones and the timing of
achieving these milestones is primarily dependent upon the outcome of the
licensee's activities and is uncertain at this time.

As of March 31, 2022, we had cash and cash equivalents of $183.0 million. Since
inception we have incurred net losses. As of March 31, 2022, we had an
accumulated deficit of $633.7 million. Substantially all of our net losses have
resulted from costs incurred in connection with our research and development
programs, our commercial launch of COSELA, and from selling, general and
administrative expenses associated with our operations. We expect to continue to
incur significant expenses and increasing operating losses. We expect our
research and development, commercial activities, and selling, general and
administrative expenses will continue to increase in connection with our ongoing
and future activities as we:
• continue development of trilaciclib, including initiation of additional

clinical trials;

• identify and develop new product candidates;

• seek additional marketing approvals for trilaciclib upon successful completion

of clinical trials;

• grow our sales, marketing and distribution infrastructure to commercialize

COSELA and any future products for which we may obtain marketing approval;

• achieve market acceptance of our product in the medical community and with


  third-party payors;


                                       25
--------------------------------------------------------------------------------

• maintain, expand and protect our intellectual property portfolio;

• hire additional personnel;

• enter into collaboration arrangements, if any, for the development of our

product or in-license other products and technologies;

• identify and develop new product candidates;

• add operational, financial and management information systems and personnel,

including personnel to support our product development and planned future

commercialization efforts; and

• continue to incur increased costs as a result of operating as a public company.

Components of our Results of Operations

Revenue



On February 12, 2021, COSELATM was approved by the FDA and we began generating
revenue for the product sales of COSELA in March 2021. Prior to the approval of
COSELA, our revenues have been derived from our license agreements.

We entered into an exclusive license agreement with Nanjing Simcere Dongyuan
Pharmaceutical Co., Ltd ("Simcere") in August 2020 and granted them the rights
to develop and commercialize trilaciclib in Greater China (mainland China, Hong
Kong, Macau, and Taiwan) (the "Simcere Territory"). We received an upfront
payment of $14.0 million (less applicable withholding taxes of $1.4 million) in
September 2020. This was recognized as revenue once the transfer of the related
technology and know-how was completed in the fourth quarter of 2020. We have the
potential to receive $156.0 million upon reaching development and commercial
milestones, and receive tiered low double-digit royalties on annual net sales of
trilaciclib in the Simcere Territory. We did not receive any development
milestones during the three months ended March 31, 2022.

We entered into an exclusive license agreement with EQRx, Inc. ("EQRx") in July
2020 and granted them the rights to develop and commercialize lerociclib in the
U.S, Europe, Japan and all other global markets, excluding the Asia-Pacific
region (except Japan) (the "EQRx Territory"). We received an upfront payment of
$20.0 million in August 2020. This was recognized as revenue in September 2020
when we transferred the license and related technology and know-how. We have the
potential to receive $290.0 million upon reaching development and commercial
milestones, and receive tiered royalties ranging from mid-single digits to
mid-teens based on annual net sales of lerociclib in the EQRx Territory. We did
not receive any development milestones during the three months ended March 31,
2022.

We entered into an exclusive license agreement with Genor Biopharma Co. Inc.
("Genor") in June 2020 and granted them the rights to develop and commercialize
lerociclib in the Asia-Pacific Region, excluding Japan (the "Genor Territory").
We received an upfront payment of $6.0 million in July 2020. This was recognized
as revenue in September 2020 when we transferred the license and related
technology and know-how. We have the potential to receive $40.0 million upon
reaching development and commercial milestones, and receive tiered royalties
ranging from high single to low double-digits based on annual net sales of
lerociclib in the Genor Territory. We did not receive any development milestones
during the three months ended March 31, 2022.

We entered into an exclusive license agreement with Incyclix Bio, LLC
("Incyclix"), formerly ARC Therapeutics, LLC, a company primarily owned by a
former board member, in May 2020. We granted Incyclix an exclusive, worldwide,
royalty-bearing license of its CDK2 inhibitor compounds in exchange for an
upfront payment and equity in Incyclix with a total value of approximately $2.1
million, which resulted in the recognition of related party revenue. We are
entitled to receive additional milestone payments and sales-based royalties, and
has right of first negotiation to re-acquire these assets.

Operating expenses



We classify our operating expenses into three categories: cost of goods sold,
research and development and selling, general and administrative expenses.
Personnel costs, including salaries, benefits, bonuses, and stock-based
compensation expense, comprise a significant component of each of these expense
categories. We allocate expenses associated with personnel costs based on the
nature of work associated with these resources. In addition, costs to sell and
market COSELA are included within selling, general and administrative expense
categories.

                                       26
--------------------------------------------------------------------------------

Cost of goods sold



Cost of goods sold includes direct and indirect costs related to the
manufacturing and distribution of COSELA, including third-party manufacturing
costs, packaging services, freight-in, third-party logistics costs associated
with COSELA, and personnel costs. Cost of goods sold may also include period
costs related to certain inventory manufacturing services and inventory
adjustment charges.

Research and development expenses

The largest component of our total operating expenses since inception has been research and development activities, including the preclinical and clinical development of our product candidates.

Research and development costs are expensed as incurred. Our research and development expense primarily consists of: • salaries and personnel-related costs, including bonuses, benefits and any

stock-based compensation, for our scientific personnel performing or managing

out-sourced research and development activities;

• costs incurred under agreements with contract research organizations and

investigative sites that conduct preclinical studies and clinical trials;

• costs related to manufacturing pharmaceutical active ingredients and drug

products for preclinical studies and clinical trials;

• costs related to upfront and milestone payments under in-licensing agreements;

• fees paid to consultants and other third parties who support our product

development; and

• allocated facility-related costs and overhead.




The successful development of our products are highly uncertain. Products in
later stages of clinical development generally have higher development costs
than those in earlier stages of clinical development, primarily due to the
increased size and duration of later-stage clinical trials. Accordingly, we
expect research and development costs to increase as we conduct later stage
clinical trials. However, we do not believe that it is possible at this time to
accurately project total program-specific expenses through commercialization.
Our expenditures on current and future preclinical and clinical development
programs are subject to numerous uncertainties in timing and cost to completion.
The duration, costs and timing of clinical trials and development of our
products will depend on a variety of factors, including:
• the scope, rate of progress, and expenses of our ongoing as well as any

additional clinical trials and other research and development activities;

• future clinical trial results;

• achievement of milestones requiring payments under our in-licensing agreements;

• uncertainties in clinical trial enrollment rates or drop-out or discontinuation

rates of patients;

• potential additional studies requested by regulatory agencies;

• significant and changing government regulation; and

• the timing and receipt of any regulatory approvals.




We track research and development expenses on a program-by-program basis only
for clinical-stage product candidates. Preclinical research and development
expenses and chemical manufacturing research and development expenses are not
assigned or allocated to individual development programs. As of the first
quarter of 2022, we had two clinical-stage products, trilaciclib and
rintodestrant.

Selling, general and administrative expenses



Selling, general and administrative expenses consist of personnel costs,
allocated expenses and other expenses for outside professional services,
including legal, audit and accounting services. Personnel costs consist of
salaries, bonuses, benefits and stock-based compensation. Other selling, general
and administrative expenses include facility-related costs not otherwise
allocated to research and development expense, professional fees,
commercialization costs, expenses associated with obtaining and maintaining
patents and costs of our information systems. We anticipate that our selling,
general and administrative expenses will continue to increase in the future as
we increase our headcount to support our continued research and development and
commercialization of COSELATM.

                                       27
--------------------------------------------------------------------------------



We expect to continue to incur additional selling, general and administrative
expenses in the future in connection with the commercialization of COSELA, as we
support continued research and development activities, and as we support our
operations in a public company environment, including expenses related to
compliance with the rules and regulations of the SEC and Nasdaq, additional
insurance expenses, and expenses related to investor relations activities.

Total other income (expense), net

Total other income (expense), net consists of interest income earned on cash and cash equivalents and interest expenses incurred under our loan and security agreement with Hercules.

Income taxes



To date, we have not been required to pay U.S. federal or state income taxes
because we have not generated taxable income. Income tax expense recognized in
2021 related to the foreign withholding taxes incurred as a result of the
milestone payments received from the Simcere license agreement during the
quarter. We did not recognize any income tax expense for the three months ended
March 31, 2022.

Product sales, net

Product sales, net was $5.5 million and $0.6 million for the three months ended
March 31, 2022, and 2021, respectively. The revenue for the three months ended
March 31, 2022 related to the product sales of COSELA. We received FDA approval
on February 12, 2021 and the product was commercially available beginning March
2, 2021.

License Revenue

License revenue was $1.4 million and $13.6 million for the three months ended
March 31, 2022, and 2021, respectively. The revenue for the three months ended
March 31, 2022, primarily related to revenue recognized from amounts to be
reimbursed by EQRx and Simcere for the costs associated with the clinical
trials.

                                       28
--------------------------------------------------------------------------------

Cost of goods sold

Cost of goods sold was $0.7 million and $0.2 million for the three months ended March 31, 2022, and 2021, respectively, which relates to our third-party logistics costs for the sales of COSELA and personnel costs.

Research and development



Research and development expenses were $26.3 million for the three months ended
March 31, 2022, compared to $16.5 million for the three months ended March 31,
2021. The increase of $9.8 million, or 59%, was primarily due to an increase of
$10.7 million in clinical trial costs offset by a decrease of $0.9 million in
costs for manufacturing of active pharmaceutical ingredients and drug product to
support clinical trials. The following table summarizes our research and
development expenses allocated to trilaciclib, rintodestrant, lerociclib and
unallocated research and development expenses for the periods indicated:

Selling, general and administrative



Selling, general and administrative expenses were $26.7 million for the three
months ended March 31, 2022, compared to $23.0 million for the three months
ended March 31, 2021. The increase of $3.7 million, or 16%, was due to an
increase of $4.3 million in personnel costs due to increased headcount, of which
$0.1 million related to non-cash stock compensation expense, and an increase of
$0.1 million in professional services, insurance and other administrative costs.
The increase is offset by a decrease in $0.5 million in medical affairs costs
and $0.2 million in commercialization activities.

Total other income (expense), net



Total other income (expense), net was $(2.4) million for the three months ended
March 31, 2022, as compared to $(0.8) million for the three months ended
March 31, 2021. The increase of $1.6 million, or 214%, was primarily due to an
increase in interest expense on our loan payable during the three months ended
March 31, 2022, as compared to the three months ended March 31, 2021.

Income tax expense



There was no income tax expense recognized for the three months ended March 31,
2022, as compared to $0.1 for the three months ended March 31, 2021. Income tax
expense in the prior period related to the foreign withholding taxes incurred as
a result of the development milestone payments received from the Simcere license
agreement during the quarter.


Liquidity and Capital Resources



We have incurred cumulative losses and negative cash flows from operations since
our inception in 2008. As of March 31, 2022, we had an accumulated deficit of
$633.7 million. We anticipate that we will continue to incur losses.

As of March 31, 2022, we had cash and cash equivalents of $183.0 million. To
date, we have funded our operations primarily through proceeds from our initial
public offering, our follow-on stock offerings, our debt agreement with Hercules
Capital, Inc. ("Hercules"), and proceeds from our license agreements. Under our
licensing arrangements, we are eligible to receive certain development and
sales-based milestones. Our ability to earn these milestones and the timing of
achieving these milestones is primarily dependent upon the outcome of the
licensee's activities and are uncertain at this time.

Shelf registration statement



On July 2, 2021, we filed an automatically effective shelf registration
statement (the "2021 Form S-3") with the Securities and Exchange Commission (the
"SEC"). Each issuance under the shelf registration statement would have required
the filing of a prospectus supplement identifying the amount and terms of
securities to be issued. The 2021 Form S-3 did not limit the amount of
securities that could have been issued thereunder.

Since we no longer qualify as a "well-known seasoned issuer" as such term is
defined in Rule 405 under the Securities Act of 1933, as amended, at the time of
the filing of our 2021 Form 10-K in February 2022, we filed an automatic
post-effective amendment to the 2021 Form S-3 on Form POSASR prior to the filing
of our 2021 Form 10-K, which became effective upon filing, to register for sale
up to $300.0 million of any combination of our common stock, preferred stock,
debt securities, warrants, rights and/or units from time to time and at prices
and on terms that we may determine and, as required by SEC rules, and another
post-effective amendment to the 2021 Form S-3 on Form POS AM after the filing of
our 2021 Form 10-K. The post-effective amendment to the 2021 Form S-3 on Form
POS AM was declared effective by the SEC on May 3, 2022 and the 2021 Form S-3
will remain in effect for up to three years from the date it originally became
effective, which was July 2, 2021. We make no assurances as to our ability to
continue to use the 2021 Form S-3.

At-the-market offerings



On June 15, 2018, we entered into a sales agreement for "at the market
offerings" with Cowen and Company, LLC ("Cowen"), which allows us to issue and
sell shares of common stock pursuant to a shelf registration statement for total
gross sales proceeds of up to $125.0 million from time to time through Cowen,
acting as our agent. Between June 18, 2018 and August 2, 2018, we sold 752,008
shares of common stock pursuant to this agreement resulting in $36.1 million in
net proceeds, realizing $12.1 million in the second quarter and the remaining
$24.0 million by August 2, 2018.

Between January 14, 2021 and February 9, 2021, we sold 3,513,027 shares of common stock pursuant to this agreement resulting in $86.4 million in net proceeds. As of February 9, 2021, we have used the entirety of the remaining availability under the sales agreement with Cowen.



In connection with the 2021 Form S-3, on July 2, 2021, we entered into a sales
agreement for "at the market offerings" with Cowen, which allowed us to issue
and sell shares of common stock pursuant to the 2021 Form S-3 for total gross
sales proceeds of up to $150.0 million from time to time through Cowen, acting
as our agent (the "2021 Sales Agreement"). We did not sell any shares of common
stock or other securities under the 2021 Sales Agreement and we terminated the
2021 Sales Agreement on February 23, 2022. Also, on February 23, 2022, we
entered into a sales agreement for "at the market offerings" with Cowen, which
allows us to issue and sell shares of common stock pursuant to the 2021 Form S-3
for total gross sales proceeds of up to $100.0 million from time to time through
Cowen, acting as our agent. As of the date hereof, we have not sold any shares
of common stock or other securities under this sales agreement.



Loan and Security Agreement with Hercules



On May 29, 2020, we entered into a loan and security agreement with Hercules
Capital, Inc. ("Hercules") under which Hercules has agreed to lend us up to
$100.0 million, to be made available in a series of tranches, subject to
specified conditions. We borrowed $20.0 million at loan closing. The term of the
loan is approximately 48 months, with a maturity date of June 1, 2024. No
principal payments are due during an interest-only period, commencing on the
initial borrowing date and continuing through June 1, 2022. The interest only
period may be extended through January 1, 2023 upon satisfaction of certain
milestones. Following the interest only period, we will repay the principal
balance and interest of the advances in equal monthly installments through June
1, 2024.

On March 31, 2021, we entered into the First Amendment to Loan and Security
Agreement (the "First Amendment") with Hercules whereby the Company drew the
remaining $10.0 million of the first tranche and the interest rate and financial
covenants were amended. Unless loan advances exceeded $40.0 million, no
financial covenants were required.

On November 1, 2021, we entered into a Second Amendment to the Loan and Security
Agreement with Hercules under which Hercules has agreed to lend us up to $150.0
million, to be made available in a series of tranches, subject to certain terms
and conditions. The first tranche was increased to $100.0 million. At close of
the Second Amendment, we borrowed an additional $45.0 million from tranche 1
with $25.0 million remaining to be borrowed through September 15, 2022. No
principal payments are due during an interest-only period, commencing on the
close of the Second Amendment and continuing through December 1, 2024. The
interest only period may be extended through December 1, 2025, in quarterly
increments, subject to compliance with covenants of the Second Amendment.
Following the interest only period, we will repay the principal balance and
interest of the advances in equal monthly installments through the maturity date
of November 1, 2026.

Genor Territory and will be responsible, at its sole cost, for obtaining supply
of lerociclib to meet its development, regulatory approval, and
commercialization obligations under the agreement. We did not recognize any
revenue related to development milestones in the first quarter of 2022.

EQRx License Agreement



On July 22, 2020, we entered into an exclusive license agreement with EQRx, Inc.
("EQRx") for the development and commercialization of lerociclib in the U.S.,
Europe, Japan and all other global markets, excluding the Asia-Pacific region
(except Japan) (the "EQRx Territory"). Under the license agreement, we granted
to EQRx an exclusive, royalty-bearing, non-transferable license, with the right
to grant sublicenses, to develop, obtain, hold and maintain regulatory approvals
for, and commercialize lerociclib in the EQRx Territory.

Under the license agreement, EQRx agreed to pay us a non-refundable, upfront
cash payment of $20.0 million with the potential to pay an additional $290.0
million upon reaching certain development and commercial milestones. In
addition, EQRx will pay us tiered royalties ranging from mid-single digits to
mid-teens based on annual net sales of lerociclib in the EQRx Territory. The
upfront cash payment was received in August 2020. In September 2020, we
transferred to EQRx the related technology and know-how that is necessary to
develop, seek regulatory approval for, and commercialize lerociclib in the EQRx
Territory. EQRx will be responsible for the development of the product in the
EQRx Territory. We will continue until completion, as the clinical trial
sponsor, its two primary clinical trials at EQRx's sole cost and expense. EQRx
will reimburse us for all of its out-of-pocket costs incurred after the
effective date of the license agreement in connection with these clinical
trials. We will invoice EQRx within 30 days following the end of the quarter,
and EQRx will pay within 30 days after its receipt of such invoice. We did not
recognize any revenue related to development milestones in the first quarter of
2022.

Simcere License Agreement

On August 3, 2020, we entered into an exclusive license agreement with Nanjing
Simcere Dongyuan Pharmaceutical Co., Ltd ("Simcere") for the development and
commercialization of trilaciclib in all indications in Greater China (mainland
China, Hong Kong, Macau, and Taiwan) (the "Simcere Territory"). Under the

71,662 $ (109,828 )

Net cash used in operating activities

During the three months ended March 31, 2022, net cash used in operating activities was $38.2 million which consisted primarily of a net loss of $49.2 million offset by non-cash stock compensation expense of $5.8 million, $0.1 million of depreciation expense, $0.5 million in amortization of debt issuance costs, $0.6 million of non-cash interest expense, $0.2 million in non-cash equity interest, and an increase of $3.8 million in net operating assets and liabilities.



During the three months ended March 31, 2021, net cash used in operating
activities was $26.9 million, which consisted primarily of a net loss of $26.4
million and a decrease in net operating assets and liabilities of $7.0 million,
partially offset by non-cash stock compensation expense of $5.9 million, $0.1
million of depreciation expense, $0.3 million in amortization of debt issuance
costs, and $0.2 million of non-cash interest expense.

Net cash used in operating activities increased by $11.3 million as compared to
the three months ended March 31, 2021 primarily due to increase in net loss from
an increase in research costs related to clinical trials as well as
administrative costs operating as a commercial company.

Net cash used in investing activities

During the three months ended March 31, 2022, and the three months ended March 31, 2021, there was no cash provided or used in investing activities.

Net cash provided by financing activities



During the three months ended March 31, 2022, net cash provided by financing
activities was $18 thousand, which consisted of proceeds from exercise of stock
options.

During the three months ended March 31, 2021, net cash provided by financing
activities was $98.5 million, which consisted of $86.4 million in net proceeds
from our ATM offering after deducting cash paid in the quarter for underwriting
discounts and commissions and other expenses, $9.9 million in net proceeds from
debt funding, and $2.2 million from proceeds from the exercise of stock options.


Operating capital requirements and plan of operations



To date, we have generated limited revenue from product sales. We expect our
expenses to increase as we continue the development of and seek additional
regulatory approvals for trilaciclib, and continue to commercialize COSELA. As
described in the risk factors included in the 2021 Form 10-K, we are subject to
all of the risks inherent in the development of new products, and we may
encounter unforeseen expenses, difficulties, complications, delays and other
unknown factors that may adversely affect our business.

We believe that our existing cash and cash equivalents will be sufficient to fund our projected cash needs for at least the next 12 months.


                                       32
--------------------------------------------------------------------------------



We have based our projections of operating capital requirements on assumptions
that may prove to be incorrect and we may use all of our available capital
resources sooner than we expect. Because of the numerous risks and uncertainties
associated with research, development and commercialization of pharmaceutical
products, we are unable to estimate the exact amount of our operating capital
requirements. Our future funding requirements will depend on many factors,
including, but not limited to:

• the scope, progress, results and costs of nonclinical development,

laboratory testing and clinical trials for our product candidates;

• the scope, prioritization and number of our research and development

programs;

• the costs, timing and outcome of regulatory review of our product candidates;

• the extent to which we enter into non-exclusive, jointly funded clinical


        research collaboration arrangements, if any, for the development of our
        product candidates in combination with other companies' products;

• our ability to establish such collaborative co-development arrangements on

favorable terms, if at all;




    •   the achievement of milestones or occurrence of other developments that
        trigger payments under our license agreements and any collaboration
        agreements into which we enter;


    •   the extent to which we are obligated to reimburse, or entitled to
        reimbursement of, clinical trial costs under future collaboration
        agreements, if any;

• the extent to which we acquire or in-license product candidates and

technologies and the terms of such in-licenses;

• the costs of commercialization activities, including product sales,


        marketing, manufacturing and distribution, for any of our product
        candidates for which we receive marketing approval;


  • revenue received from commercial sales of our product candidates; and

• the costs of preparing, filing and prosecuting patent applications,

maintaining and enforcing our intellectual property rights and defending

intellectual property-related claims.




Until such time, if ever, as we can generate substantial revenues, we expect to
finance our cash needs through a combination of equity offerings, debt
financings, other third-party funding, marketing and distribution arrangements
and other collaborations, strategic alliances and licensing arrangements. We do
not have any committed external source of funds except for amounts included
under our licensing arrangements and the loan agreement with Hercules. To the
extent that we raise additional capital through the sale of equity or
convertible debt securities, our stockholders' ownership interest will be
diluted, and the terms of these securities may include liquidation or other
preferences that adversely affect your rights as a common stockholder. Debt
financing, if available, may involve agreements that include covenants limiting
or restricting our ability to take specific actions, such as incurring
additional debt, making capital expenditures or declaring dividends. If we raise
funds through additional collaborations, strategic alliances or licensing
arrangements with third parties, we may have to relinquish valuable rights to
our technologies, future revenue streams, research programs or product
candidates or to grant licenses on terms that may not be favorable to us. If we
are unable to raise additional funds when needed, we may be required to delay,
limit, reduce or terminate our product development or future commercialization
efforts or grant rights to develop and market product candidates that we would
otherwise prefer to develop and market ourselves.

Contractual Obligations, Commitments and Contingencies



There have been no material changes to our contractual obligations during the
current period from those disclosed in our Annual Report on Form 10-K for year
ended December 31, 2021.

Off-Balance Sheet Arrangements

We did not have, during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under applicable SEC rules.

Critical Accounting Policies and Significant Judgments and Estimates



Our management's discussion and analysis of our financial condition and results
of operations is based on our financial statements, which have been prepared in
accordance with accounting principles generally accepted in the United States of
America, or U.S. GAAP. The preparation of our financial statements requires us
to make estimates, judgments, and assumptions that affect the reported amounts
of assets and liabilities, the disclosure of contingent assets and liabilities
as of the dates of the balance sheet, and the reported amount of expenses
incurred during the reporting period. In accordance with U.S. GAAP, we evaluate
our estimates and judgments on an ongoing basis. Our estimates are based on our
historical experience and on various other factors that we believe are
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying value of assets and liabilities that are not
readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions.

We believe that our accounting policies are critical to the process of making
significant judgments and estimates in the preparation of our financial
statements and understanding and evaluating our reported financial results. We
discussed our accounting policies and significant assumptions used in our
estimates in Note 2 of our audited financial statements included in our 2021
Form 10-K. There have been no material changes during the three months ended
March 31, 2022, to our critical accounting policies, significant judgments and
estimates disclosed in our 2021 Form 10-K.
