BOSTON - CureVac N.V. (Nasdaq: CVAC) ('CureVac'), a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid ('mRNA'), today announced financial results for the second quarter and first half of 2023 and provided a business update.

'During the first six months of 2023, we continued building on the momentum from the strong start to the year. In particular, our clinical development programs in prophylactic vaccines, in collaboration with GSK, and our in-house cancer vaccine programs are advancing well and are on track since the start of clinical trials with differentiated candidates based on our advanced second-generation mRNA backbone. The Phase 2 study in COVID-19, assessing booster doses of mono- and bivalent mRNA vaccine candidates, is expected to provide data early in the first half of 2024. In oncology, our Phase 1 study in patients with resected glioblastoma has progressed through the first dose cohort without safety concerns, enabling opening of the second dose patient cohort,' said Dr. Alexander Zehnder, Chief Executive Officer of CureVac. 'Our unwavering commitment to innovation has enabled us to further expand our intellectual property portfolio, strengthening our mRNA technology ownership. Accordingly, we recently bolstered our position in the litigations in Germany and the U.S. by asserting new intellectual property rights, demonstrating that we continue to be at the forefront of innovation in the mRNA field.'

'After successfully raising $250 million in gross proceeds through a follow-on offering during the first quarter of 2023, we are focused on executing on our programs and priorities and continuing CureVac's transformation from a research-oriented to a fully integrated and commercial-ready biopharma company,' said Pierre Kemula, Chief Financial Officer of CureVac. 'We continue to grow the company, expand our competencies and advance our pipeline to deliver on the broad promise of mRNA technology.'

Selected Business Updates

Prophylactic Vaccines

Executing on Broad Second-Generation mRNA Vaccine Program, Jointly Developed with GSK

CureVac continues to advance its broad clinical development program in prophylactic vaccines in collaboration with GSK. Positive preliminary data reported in early 2023 from Phase 1 studies with modified, monovalent mRNA candidates in COVID-19 and flu provided strong validation of CureVac's mRNA technology platform. All jointly tested candidates are based on CureVac's proprietary second-generation mRNA backbone, targeting improved intracellular mRNA translation for early and strong immune responses. The second-generation mRNA backbone is expected to enable protection against one or more emerging COVID-19 variants or multiple strains of other infectious diseases, such as flu, with potential for combination vaccines against multiple different viruses as well.

On August 1, CureVac announced dosing of the first participant in a Phase 2 study of monovalent and bivalent modified mRNA COVID-19 vaccine candidates, developed in collaboration with GSK. The Phase 2 study will evaluate safety, reactogenicity and immune responses of single booster doses of two modified mRNA COVID-19 vaccine candidates. The monovalent candidate, CV0601, encodes the spike protein of the omicron BA.4-5 variant. In line with the current standard of care, the bivalent candidate, CV0701, encodes the spike protein of both the omicron BA.4-5 variant as well as the original SARS-CoV-2 virus. The study is active-controlled, including a licensed bivalent COVID-19 comparator vaccine. Enrollment started at clinical sites in Australia. The study is expected to enroll approximately 415 healthy adult participants. An initial data readout of the study is expected early in the first half of 2024.

Oncology

Broadening of Oncology Footprint with mRNA Cancer Vaccines

CureVac continues to execute on its strategy to develop the next generation of targeted mRNA-based cancer vaccines and expand in the oncology area with its differentiated antigen discovery approach. An initial portfolio of cancer vaccine candidates will be based on CureVac's second-generation mRNA backbone, which recently established clinical validation in prophylactic vaccines. CureVac focuses on two approaches: 1) the development of off-the-shelf cancer vaccines based on tumor antigens shared across different cancer indications and 2) the development of fully personalized cancer vaccines based on a patient's individual tumor genomic profile.

CureVac entered the execution phase of its cancer vaccine development strategy with the start of a Phase 1 study in patients with resected glioblastoma. Dosing of the first patient with its cancer vaccine candidate, CVGBM, was announced on June 20. Since then, recruitment has successfully progressed without safety concerns at the doses tested to date. CVGBM is based on CureVac's proprietary second-generation mRNA backbone and features a single unmodified mRNA encoding eight epitopes derived from known tumor-associated antigens with demonstrated relevance in glioblastoma.

The open-label study evaluates the safety and tolerability of CVGBM in up to 54 patients with newly diagnosed and surgically resected MGMT-unmethylated glioblastoma or astrocytoma with a molecular signature of glioblastoma. The study is being conducted in Germany, Belgium and the Netherlands. CVGBM is administered as a monotherapy after surgical resection and completion of radiotherapy with or without chemotherapy. The study consists of two parts, a dose-escalation part (Part A) and a dose-expansion part (Part B). In the initiated Part A, patients will receive a total of seven intramuscular administrations of CVGBM at escalating doses in the range of 12 to 100 -microg on days 1, 8, 15, 29, 43, 57, and 71. In patients without disease progression, vaccinations can continue beyond day 71 every 6 weeks until one year after the first CVGBM vaccination, disease progression or undue toxicity. More information can be found at clinicaltrials.gov (NCT05938387). A first data readout is expected in the second half of 2024.

About CureVac

CureVac (Nasdaq: CVAC) is a global biopharmaceutical company in the field of messenger RNA (mRNA) technology, with more than 20 years of expertise in developing, optimizing, and manufacturing this versatile biological molecule for medical purposes. The principle of CureVac's proprietary technology is the use of optimized mRNA as a data carrier to instruct the human body to produce its own proteins capable of fighting a broad range of diseases. In July 2020, CureVac entered in a collaboration with GSK to jointly develop new products in prophylactic vaccines for infectious diseases based on CureVac's second-generation mRNA technology. This collaboration was later extended to the development of second-generation COVID-19 vaccine candidates, and modified mRNA vaccine technologies. Based on its proprietary technology, CureVac has built a deep clinical pipeline across the areas of prophylactic vaccines, cancer therapies, antibody therapies, and the treatment of rare diseases. CureVac N.V. has its headquarters in Tubingen, Germany, and has more than 1,100 employees across its sites in Germany, the Netherlands, Belgium, Switzerland and the U.S.
