TÜBINGEN, Germany/BOSTON, USA – May 30, 2023

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 first quarter of 2023 and provided a business update.

“During the first quarter of 2023, we continued to execute on our multipronged clinical development strategy in prophylactic vaccines with the initiation of a Phase 1/2 clinical study in seasonal flu, evaluating multivalent, modified mRNA vaccine candidates. In oncology, the first proof-of-principle clinical study to validate our second-generation mRNA backbone in patients with glioblastoma has been activated and is expected to start recruitment shortly,” said Alexander Zehnder, Chief Executive Officer at CureVac. “As we continue to make progress with our pipeline, we are also seeing progress in our efforts to have our intellectual property innovations recognized. Our scientists have pioneered fundamental breakthroughs in mRNA technology over the last two decades. These contributions have underpinned many develop­ments in the mRNA field and resulted in a broad IP portfolio that we intent to defend and further strengthen in pursuit of our mission to leverage our mRNA technology for the development of transformative medicines.”

“In the first quarter of 2023, we successfully raised $250 million in gross proceeds in a follow-on offering, extending our cash runway into 2025 and successfully diversifying our investor base with new healthcare-specialized shareholders that share the company’s vision” said Pierre Kemula, Chief Financial Officer of CureVac. “We continue to build the company and advance our pipeline based on our unique mRNA technology to bring new and better solutions to people and patients in need.”

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.

The flu clinical development program was broadened on May 8, 2023, when dosing of the first participant was announced in the Phase 1 part of a combined Phase 1/2 study of multivalent, modified mRNA seasonal flu vaccine candidates. The study evaluates flu vaccine candidates for safety, reactogenicity and immune responses. The first, Phase 1 part of the trial is being conducted in the U.S. and Belgium. The tested multivalent vaccine candidates address all four WHO-recommended flu strains and are compared to a licensed flu comparator vaccine.

Protection of Intellectual Property Rights

Over the last 23 years, CureVac has developed proprietary foundational technology related to mRNA design, delivery and manufacturing that has materially contributed to the development of safe and efficacious COVID-19 vaccines.

On May 19, CureVac announced the granting of its motion to transfer U.S. patent litigation initiated by Pfizer/BioNTech in late July 2022 from the federal district court of Massachusetts to the Eastern District of Virginia. The transfer is expected to significantly accelerate progress of the litigation, allowing for a likely 2024 trial date.

The motion to transfer the case is part of a broadened counterclaim CureVac filed on May 19, 2023, that alleges infringement of nine U.S. patents by the manufacture and sale of the SARS-CoV-2 vaccine Comirnaty®: 11,135,312; 11,149,278; 11,286,492; 11,345,920; 10,760,070; 11,241,493; 11,471,525; 11,576,966; and 11,596,686. This significantly expands the scope of the case beyond the three patents for which Pfizer/BioNTech had originally sought confirmation of non-infringement. These nine patents cover foundational and highly relevant separate innovations in mRNA vaccine design, formulation and manufacturing specific to SARS-CoV-2 vaccines.

Corresponding patent litigation in Germany has been ongoing since June 2022. One of the patents at issue (EP 1 857 122) was challenged in a nullity action by Pfizer/BioNTech in September 2022. A preliminary opinion issued in April 2023 by the German Federal Patent Court supports the validity of the patent. The German litigation, which originated with a filing by CureVac regarding four of its intellectual property rights, now also covers a fifth intellectual property right (EP 3 708 668 B1).

CureVac does not seek an injunction nor intend to take legal action that impedes the production, sale or distribution of Comirnaty® by BioNTech and its partner Pfizer. The development of safe and efficacious COVID-19 vaccines is based on decades of scientific research and innovation, supported by CureVac as the earliest pioneer in mRNA technology. Accordingly, CureVac’s intellectual property rights need to be acknowledged and respected in the form of fair compensation that enables reinvestment into the further advancement of mRNA technology and the ongoing development of new classes of life-saving medicines.

Financial Update for the First Quarter of 2023

Cash Position

Cash and cash equivalents amounted to €617.5 million at the end of March 2023, increasing from €495.8 million at the end of 2022. The increase was mainly driven by €219.8 million in net proceeds raised in a follow-on offering during February 2023. In the first three months of 2023, cash used in operations was mainly allocated to payments in connection with ongoing R&D activities and the purchase of raw materials.


Revenues amounted to €7.1 million for the first quarter of 2023, representing a decrease of €17.3 million, or 71%, from €24.4 million for the same period in 2022.

The decrease was primarily driven by lower revenues from the two GSK collaborations. For both GSK collaboration agreements, total revenues of €6.5 million were recognized for the three months ending March 31, 2023, compared to €23.7 million in the prior year period at which point an important part of the milestone related to starting the flu clinical trial in Panama was recognized.

Operating Result

Operating loss amounted to €60.4 million for the first quarter of 2023, representing an increase of €45.1 million, from €15.3 million for the same period in 2022.

The operating result was affected by several key drivers:

  • Cost of sales decreased primarily in relation to lower write-off of raw materials. In addition, the first quarter of 2022 was impacted by additional costs related to the termination of CMO activities for the first generation COVID-19 vaccine.
  • Research and development expenses increased primarily with enhanced activity in infectious disease and oncology R&D projects and development of the workforce. The first quarter of 2022 was positively impacted by €6.8 million related to the reversal of an outstanding CRO provision. Additionally, in the first quarter of 2022, Research and Development costs were positively impacted by a one-off net gain for a change in the contract termination provision resulting primarily in GSK taking over, from the Company, committed capacity at a CMO.
  • In the first quarter of 2022, other income was positively impacted by a one-off compensation from GSK amounting to €32.5 million for reimbursement of prepayments and production set-up activities at a CMO.

Financial Result (Finance Income and Expenses)

Net financial result for the first quarter of 2023, amounted to €3.0 million, or an increase of €2.9 million from €0.1 million for the same period in 2022. This was mainly driven by interest income on cash investments.

Pre-Tax Loss

Pre-tax loss was €57.4 million for the first quarter of 2023 compared to €15.2 million in the same period of 2022.
