HAMILTON, ON and BOSTON, March 20, 2024 /CNW/ -- Fusion Pharmaceuticals Inc. (Nasdaq: FUSN), a clinical-stage oncology company focused on developing next-generation radiopharmaceuticals as precision medicines, today reported financial results for the fourth quarter and full year ended December 31, 2023, and provided an update on clinical and corporate developments.
Chief Executive Officer John Valliant, Ph.D., commented, "We entered 2024 with strong momentum focused on execution to advance our pipeline of targeted alpha therapies, and we are pleased to recently have achieved several critical milestones. For our lead program, FPI-2265, we expect to initiate the Phase 2 portion of the registrational program in metastatic castration-resistant prostate cancer (mCRPC) in the second quarter of this year. Acknowledging the substantial and expanding market for patients in the post-PLUVICTO™ setting we believe FPI-2265, which is positioned to be the first actinium-based PSMA targeted radiopharmaceutical to market, will effectively address a crucial unmet need for patients with progressive disease. We look forward to presenting data from the TATCIST trial at AACR in April.
Dr. Valliant continued, "We also continue to advance our other clinical-stage programs, including the ongoing Phase 1 study of FPI-1434, which has demonstrated a promising safety profile and early evidence of antitumor activity. We expect to provide an update on this program around mid-year 2024. Underpinning our platform, which has produced a robust pipeline of targeted alpha therapies, is our state-of-the-art GMP manufacturing facility now operational and producing clinical doses of FPI-2265. With a strong balance sheet and secured actinium supply, we are well positioned to execute on our commitment of bringing this next generation of radiopharmaceuticals to patients in need."
Corporate Update
On March 19, 2024, Fusion announced the Company has entered into a definitive agreement to be acquired by AstraZeneca. Under the terms of the agreement, AstraZeneca, through a subsidiary, will acquire all of Fusion's outstanding shares pursuant to a plan of arrangement for a price of $21.00 per share in cash at closing plus a non-transferable contingent value right (CVR) of $3.00 per share in cash payable upon the achievement of a specified regulatory milestone.
The upfront cash portion of the consideration represents a transaction value of approximately $2 billion, a 97% premium to Fusion's closing market price of $10.64 on March 18, 2024. Combined, the upfront and maximum potential contingent value payments represent, if achieved, a transaction value of approximately $2.4 billion, a 126% premium to Fusion's closing market price on March 18, 2024. As part of the transaction, AstraZeneca will acquire the cash, cash equivalents and short-term investments on Fusion's balance sheet, which totaled $234 million as of December 31, 2023.
The transaction is expected to close in the second quarter of 2024, subject to customary closing conditions, including the approval of Fusion shareholders and regulatory clearances.
Portfolio Update
FPI-2265: A 225Ac based radiopharmaceutical targeting prostate specific membrane antigen (PSMA) for the treatment of patients with mCRPC.
In January 2024, the Company announced alignment with the FDA on its Phase 2/3 protocol for FPI-2265 in patients with mCRPC with progressive disease who have previously been treated with a 177Lu-based PSMA radiotherapy. The development plan includes a Phase 2 dose optimization lead-in, which aims to evaluate whether there are added safety and/or efficacy benefits of various dosing regimens in comparison to the validated regimen of 100kBq/kg every eight weeks, expected to be initiated in the second quarter of 2024. This Phase 2 portion is expected to complete enrollment of approximately 60 patients by the end of 2024. Following analysis of the Phase 2 data and an end of Phase 2 meeting to determine the recommended Phase 3 dosing regimen with the FDA, a Phase 3 global registrational trial in approximately 550 patients is expected to begin in 2025.
The TATCIST trial, which began as an investigator sponsored study, is designed to evaluate FPI-2265 in patients with mCRPC with progressive disease, including patients who are naïve to PSMA-targeted radiopharmaceuticals and those who have been pre-treated with 177Lu-based PSMA radiopharmaceutical therapy, completed target enrollment of 25-30 patients. The Company announced that interim data will be presented at the upcoming 2024 American Association for Cancer Research (AACR) Annual Meeting in April.
The Company is also pursuing the opportunity to potentially move this therapeutic candidate into earlier lines of treatment with combinations of FPI-2265 and olaparib. Fusion expects to initiate a combination trial in the first half of this year.
In January 2024, Fusion announced encouraging early findings from Cohort 2 in the cold/hot dosing arm of the ongoing Phase 1, multi-center, open-label clinical trial. The trial is designed to investigate the safety, tolerability, and pharmacokinetics of FPI-1434 in patients with solid tumors expressing IGF-1R. The trial is also designed to establish the maximum tolerated dose for FPI-1434 and the recommended Phase 2 dose. No dose limiting toxicities (DLTs) were observed to date in the 25 kBq/kg dose cohort. Two out of three patients completed the DLT period, and one pancreatic cancer patient discontinued treatment due to disease progression. Evidence of anti-tumor activity was observed in a heavily pre-treated patient with Ewing sarcoma after a single dose and a second patient receiving four cycles of therapy demonstrated stable disease as best response.
The Company plans to complete and further evaluate results from Cohort 2 and hold a Safety Review Committee (SRC) meeting to evaluate the emerging data. Fusion plans to share more details on the data and the FPI-1434 development program in mid-2024.
Patient enrollment and dosing is ongoing in the Phase 1, multi-center, open-label clinical trial designed to investigate the safety, tolerability, dosimetry, biodistribution, and pharmacokinetics of FPI-2059 as well as preliminary anti-tumor activity in participants with NTSR1 expressing advanced metastatic solid tumors. Fusion plans to provide guidance on timing for pharmacokinetic, imaging and safety data following early experience with FPI-2059 patient screening and enrollment.
FPI-2068: A bispecific IgG-based targeted alpha therapy (TAT) targeting EGFR-cMET.
FPI-2068 is currently being evaluated in a Phase 1 study and is being jointly developed with AstraZeneca under the companies' multi-asset collaboration agreement. FPI-2068 is a bispecific IgG-based TAT designed to deliver actinium-225 to various solid tumors that express EGFR-cMET. EGFR and cMET are both validated targets that are co-expressed in multiple tumor types, including head and neck squamous cell carcinoma, non-small cell lung cancer, colorectal cancer, and pancreatic ductal adenocarcinoma. The investigational new drug (IND) application has been cleared and Fusion is currently activating clinical trial sites.
Other Recent Updates
In January 2024, Fusion announced it had completed validation of its state-of-the-art GMP manufacturing facility and produced the first clinical dose of a TAT. The facility, which has clinical and commercial scale manufacturing capacity, is designed to support the Company's growing pipeline of TATs and is expected to be capable of producing more than 100,000 doses per year.
In February 2024, Fusion announced that it has entered into a licensing agreement with Heidelberg University and Euratom represented by the European Commission, Joint Research Centre (together, the "Licensors"). The license agreement grants Fusion exclusive worldwide rights to utilize, develop, manufacture and commercialize compounds covered by the patent, which includes 225Ac-PSMA I&T ("FPI-2265") for the treatment of prostate specific membrane antigen (PSMA)-expressing cancers. In addition, Fusion and the Licensors have signed an agreement to settle the parties' dispute related to an inter partes review ("IPR") of the patent which was instituted in August 2023 by the United States Patent and Trademark Board.
Fourth Quarter 2023 Financial Results
Cash and Investments: As of December 31, 2023, Fusion held cash, cash equivalents and investments of $247.3 million, compared to cash, cash equivalents and investments of $186.6 million as of December 31, 2022. Fusion expects its existing cash, cash equivalents and investments as of December 31, 2023, together with net proceeds from sales of common shares under the Company's at-the-market equity offering program received in January and February 2024 and net proceeds of $14.9 million from a draw down under the Company's existing debt facility in January 2024, will be sufficient to fund operations into the fourth quarter of 2025.
R&D Expenses: Research and development expenses for the fourth quarter of 2023 were $20.6 million, compared to $17.6 million for the same period in 2022. The increase was primarily due to increased manufacturing-related expenditures, as well as increased personnel-related costs.
G&A Expenses: General and administrative expenses for the fourth quarter of 2023 were $7.6 million, compared to $6.9 million for the same period in 2022. The increase was primarily due to increased consulting and personnel-related costs.
Net Loss: For the fourth quarter of 2023, Fusion reported a net loss of $28.2 million, or $0.39 per share, compared with a net loss of $24.6 million, or $0.55 per share, for the same period in 2022.
