\nSummit Therapeutics Inc. (NASDAQ: SMMT) (“Summit,” “we,” or the “Company”) today reports its financial results and provides an update on its operational progress for the first quarter ended March 31, 2025.\n<\/p>\n
Operational & Corporate Updates<\/b><\/p>\n
\nOperational progress continues with ivonescimab (SMT112), an investigational, potentially first-in-class bispecific antibody combining the effects of immunotherapy via a blockade of PD-1 with the anti-angiogenesis effects associated with blocking VEGF into a single molecule:\n<\/p>\n
- \n
- \nIn January 2023, we closed our Collaboration and License Agreement with Akeso Inc. (Akeso, HKEX Code: 9926.HK) for ivonescimab (SMT112), with which over 2,300 patients have been treated in clinical studies globally. Summit has rights to develop and commercialize ivonescimab in the United States, Canada, Europe, Japan, Latin America, including Mexico and all countries in Central America, South America, and the Caribbean, the Middle East, and Africa while Akeso retains development and commercialization rights for the rest of the world, including China.\n<\/li>\n
- \nSince in-licensing ivonescimab, we have begun our development for ivonescimab in non-small cell lung cancer (\u201cNSCLC\u201d), specifically launching Phase III clinical trials in the following proposed indications:<\/p>\n
- \n
- HARMONi<\/i>: Ivonescimab combined with chemotherapy in patients with epidermal growth factor receptor (EGFR)-mutated, locally advanced or metastatic non-squamous NSCLC who have progressed after treatment with a third-generation EGFR tyrosine kinase inhibitor (TKI)\n<\/li>\n
- HARMONi-3<\/i>: Ivonescimab combined with chemotherapy in first-line metastatic NSCLC patients\n<\/li>\n
- HARMONi<\/i>–7<\/i>: Ivonescimab monotherapy in first-line metastatic NSCLC patients with high PD-L1 expression\n<\/li>\n<\/ul>\n<\/li>\n
- \nIn October 2024, we completed enrollment in our HARMONi clinical trial. We expect to disclose topline results from HARMONi in mid-2025. Enrollment continues in HARMONi-3 and the initial patients have been enrolled in the US in HARMONi-7.\n<\/li>\n
- \nOn April 23, 2025, our partner, Akeso, announced that the HARMONi-6 Phase III clinical trial met its primary endpoint of progression-free survival (PFS) at a prespecified interim analysis conducted by an Independent Data Monitoring Committee. This trial evaluated ivonescimab combined with platinum-based chemotherapy against tislelizumab, a PD-1 inhibitor, with the same chemotherapy regimen in patients with locally advanced or metastatic squamous NSCLC, regardless of PD-L1 expression. Conducted in China by our partners at Akeso, the trial showed statistically significant and clinically meaningful improvement in PFS for ivonescimab plus chemotherapy. Akeso noted that no new safety signals were identified.<\/p>\n
- \n
- \nThis study is the first known Phase III trial in NSCLC to show significant improvement over a PD-(L)1 inhibitor combined with chemotherapy in a head-to-head setting. Following the success of Akeso\u2019s HARMONi-2 study, this is the second instance where ivonescimab-based regimens have demonstrated a significant PFS benefit in front-line treatment in NSCLC. The full data set for HARMONi-6 is planned to be presented at an upcoming major medical conference later this year.\n<\/li>\n<\/ul>\n<\/li>\n
- \nOn April 25, 2025, Akeso announced that ivonescimab was approved in China by the National Medical Products Administration (NMPA), the Chinese Health Authority, for a second indication based on the results of the HARMONi-2 trial. HARMONi-2 evaluated monotherapy ivonescimab against monotherapy pembrolizumab in patients with locally advanced or metastatic NSCLC whose tumors have positive PD-L1 expression. HARMONi-2 is a single region, multi-center, Phase III study conducted in China sponsored by Akeso with all relevant data exclusively generated, managed, and analyzed by Akeso.<\/p>\n
- \n
- \nAs a part of the review of the supplemental marketing application submitted by Akeso seeking a label expansion of ivonescimab in China, the NMPA requested that Akeso perform an interim analysis of overall survival (OS). Akeso announced that the results of this interim overall survival analysis included a clinically meaningful, strongly positive trend represented by a hazard ratio of 0.777. The analysis was conducted at 39% data maturity, with a nominal alpha level of 0.0001.\n<\/li>\n<\/ul>\n<\/li>\n
- \nIvonescimab clinical trial collaborations with leading organizations continue to progress and expand evaluating ivonescimab in solid tumor settings outside of metastatic non-small cell lung cancer.<\/p>\n
- \n
- \nAs part of our strategic collaboration with MD Anderson, two clinical trials sponsored by MD Anderson began enrolling this past quarter in cutaneous squamous cell carcinoma and glioblastoma.\n<\/li>\n
- \nWe continue to support investigator-sponsored trials (ISTs) beyond our work with MD Anderson; two ISTs have begun enrolling at the Memorial Sloan Kettering Cancer Center and the Dana Farber Cancer Institute.\n<\/li>\n
- \nAs we announced in February, our clinical trial collaboration with Pfizer will evaluate multiple antibody drug conjugates (ADCs) in combination with ivonescimab in unique solid tumor settings. The studies combining ivonescimab with Pfizer\u2019s vedotin ADCs are planned to begin later this year. We plan to review the data generated from these clinical trials as a part of our consideration for advancing our clinical development for ivonescimab beyond non-small cell lung cancer.\n<\/li>\n<\/ul>\n<\/li>\n
- \nIn March, we further strengthened our leadership team with the appointment of Robert LaCaze as Chief Commercial Officer. Prior to joining Summit, Mr. LaCaze has held senior positions at major pharmaceutical companies including Executive Vice President and Head of the Oncology Strategic Business Unit overseeing the global oncology franchise at Bayer Healthcare and Senior Vice President and Head of Global Oncology at Bristol-Myers Squibb. He is a seasoned biopharmaceutical executive with over 30 years of extensive leadership experience in commercial strategy and execution. He has a proven track record of launching multi-billion-dollar products, building and growing blockbuster drug franchises, and expanding market presence for various oncology products.\n<\/li>\n<\/ul>\n

Cash and Cash Equivalents & Short-term Investments<\/span><\/p>\n
- \n
- \nAggregate cash and cash equivalents and short-term investments were $361.3 million and $412.3 million at March 31, 2025 and December 31, 2024, respectively.\n<\/li>\n<\/ul>\n
GAAP and Non-GAAP Research and Development (R&D) Expenses<\/span><\/p>\n
- \n
- \nGAAP R&D expenses according to generally accepted accounting principles in the U.S. (\u201cGAAP\u201d) were $51.2 million for the first quarter of 2025, compared to $30.9 million for the same period of the prior year.\n<\/li>\n
- \nNon-GAAP R&D expenses were $47.1 million for the first quarter of 2025, compared to $28.5 million for the same period of the prior year.\n<\/li>\n<\/ul>\n
GAAP and Non-GAAP General and Administrative (G&A) Expenses<\/span><\/p>\n
- \n
- \nGAAP G&A expenses were $15.6 million for the first quarter of 2025, compared to $11.5 million for the same period of the prior year.\n<\/li>\n
- \nNon-GAAP G&A expenses were $8.6 million for the first quarter of 2025, compared to $4.4 million for the same period of the prior year.\n<\/li>\n<\/ul>\n

<\/b>Notes on our Non-GAAP Financial Information<\/b><\/p>\n\nNon-GAAP financial measures adjust GAAP financial measures for the items listed below. These Non-GAAP measures should be viewed in addition to, and not as a substitute for Summit’s reported GAAP results, and may be different from Non-GAAP measures used by other companies. In addition, these Non-GAAP measures are not based on any comprehensive set of accounting rules or principles. Summit management uses these non-GAAP measures for internal budgeting and forecasting purposes and to evaluate Summit\u2019s financial performance. Summit management believes the presentation of these Non-GAAP measures is useful to investors for comparing prior periods and analysing ongoing business trends and operating results.\n<\/p>\n
\nEach of non-GAAP Research and Development Expense, non-GAAP General and Administrative Expenses, non-GAAP Operating Expenses, Non-GAAP Net Loss and Non-GAAP EPS differ from GAAP in that such measures exclude the non-cash charges and costs associated with stock-based compensation.\n<\/p>\n
\nNote 1: Stock-based compensation is a non-cash charge and costs calculated for this expense can vary year-over-year depending on the stock price of awards on the date of grant as well as the timing of compensation award arrangements.\n<\/p>\n
\nNote 2: Beginning in the fourth quarter of 2024, the Company\u2019s non-GAAP financial measures will no longer exclude acquired in-process research and development expenses (\u201cIPR&D\u201d). Non-GAAP financial measures for the three months ended June 30, 2024 previously excluded $15.0 million of IPR&D which represented an upfront payment made to Akeso under an amendment to the Collaboration and License Agreement. Prior period amounts have been revised to conform to the current period presentation.\n<\/p>\n
Appendix: Glossary of Critical Terms Contained Herein<\/b><\/p>\n
Affinity<\/b> \u2013 Affinity is the strength of binding of a molecule, such as a protein or antibody, to another molecule, such as a ligand.\n<\/p>\n
Avidity<\/b> \u2013 Avidity is the accumulated strength of multiple binding interactions.\n<\/p>\n
Angiogenesis<\/b> \u2013 Angiogenesis is the development, formation, and maintenance of blood vessel structures. Without sufficient blood flow, tissue may experience hypoxia (insufficient oxygen) or lack of nutrition, which may cause cell death.1<\/sup><\/p>\n
Cooperative binding<\/b> \u2013 Cooperative binding occurs when the number of binding sites on the molecule that can be occupied by a specific ligand (e.g., protein) is impacted by the ligand\u2019s concentration. For example, this can be due to an affinity for the ligand that depends on the amount of ligand bound or the binding strength of the molecule to one ligand based on the concentration of another ligand, increasing the chance of another ligand binding to the compound.2<\/sup><\/p>\n
Immunotherapy<\/b> \u2013 Immunotherapy is a type of treatment, including cancer treatments, that help a person\u2019s immune system fight cancer. Examples include anti-PD-1 therapies.3<\/sup><\/p>\n
Intracranial<\/b> – Within the cranium or skull.\n<\/p>\n
PD-1<\/b> \u2013 Programmed cell Death protein 1 is a protein on the surface of T cells and other cells. PD-1 plays a key role in reducing the regulation of ineffective or harmful immune responses and maintaining immune tolerance. However, with respect to cancer tumor cells, PD-1 can act as a stopping mechanism (a brake or checkpoint) by binding to PD-L1 ligands that exist on tumor cells and preventing the T cells from targeting cancerous tumor cells.4<\/sup><\/p>\n
PD-L1<\/b> \u2013 Programmed cell Death Ligand 1 is expressed by cancerous tumor cells as an adaptive immune mechanism to escape anti-tumor responses, thus believed to suppress the immune system\u2019s response to the presence of cancer cells.5<\/sup><\/p>\n
PD-L1 TPS<\/b> \u2013 PD-L1 T<\/span>umor P<\/span>roportion S<\/span>core represents the percentage of tumor cells that express PD-L1 proteins.\n<\/p>\n
PFS <\/b>\u2013 Progression-Free Survival.\n<\/p>\n
RANO <\/b>\u2013R<\/span>esponse A<\/span>ssessment in N<\/span>euro-O<\/span>ncology, the standard for assessing the response of a brain or spinal cord tumor to therapy.\n<\/p>\n
SQ-NSCLC <\/b>\u2013 Non-small cell lung cancer tumors of squamous histology.\n<\/p>\n
T Cells<\/b> \u2013 T cells are a type of white blood cell that is a component of the immune system that, in general, fights against infection and harmful cells like tumor cells.6<\/sup><\/p>\n
Tetravalent<\/b> \u2013 A tetravalent molecule has four binding sites or regions.\n<\/p>\n
Tumor Microenvironment<\/b> \u2013 The tumor microenvironment is the ecosystem that surrounds a tumor inside the body. It includes immune cells, the extracellular matrix, blood vessels and other cells, like fibroblasts. A tumor and its microenvironment constantly interact and influence each other, either positively or negatively.7<\/sup><\/p>\n
VEGF <\/b>\u2013 Vascular Endothelial Growth Factor is a signaling protein that promotes angiogenesis.8<\/sup><\/p>\n
