"In the first quarter, we reported initial topline results from the Phase 1 clinical trial of KER-065 that met key objectives and yielded valuable insights. These findings position us well as we prepare to engage with regulators with the aim of advancing KER-065 to a Phase 2 clinical trial in the first quarter of 2026," said Jasbir S. Seehra, Ph.D., Chair and Chief Executive Officer. "As our Board of Directors continues its review process to evaluate strategic alternatives to enhance stockholder value for the Company, we remain focused on the execution of our strategy and advancing the development of our pipeline of novel therapeutics. We expect to report data in the second quarter of 2025 from the Phase 2 TROPOS trial evaluating cibotercept (KER-012) in patients with pulmonary arterial hypertension and we plan to evaluate the appropriate development strategy for cibotercept following that data readout."

First Quarter 2025 Financial Results

Keros reported a net income of $148.5 million in the first quarter of 2025 as compared to a net loss of $43.1 million in the first quarter of 2024. The increase of $191.6 million was largely due to revenue recognized related to Keros’ license agreement with Takeda Pharmaceuticals U.S.A., Inc., partially offset by increased research and development efforts as well as additional investments to support the achievement of Keros’ clinical and corporate goals.

Research and development expenses were $48.7 million for the first quarter of 2025 as compared to $38.3 million for the same period in 2024. The increase of $10.5 million was primarily due to additional research and development efforts, manufacturing activities and personnel expenses to support the advancement of Keros’ pipeline.

General and administrative expenses were $10.5 million for the first quarter of 2025 as compared to $10.3 million for the same period in 2024. The increase of $0.2 million was primarily due to an increase in other external expenses to support Keros’ organizational growth.

Keros’ cash and cash equivalents as of March 31, 2025 was $720.5 million compared to $559.9 million as of December 31, 2024. Based on current operating assumptions, Keros expects that its cash and cash equivalents as of March 31, 2025 will enable Keros to fund its operating expenses and capital expenditure requirements into 2029.

The review of full data, entitled: OVATION-2: A Randomized Phase I/II study Evaluating the Safety and Efficacy of IMNN-001 (IL-12 gene therapy) with Neo/Adjuvant Chemotherapy in Patients Newly- Diagnosed with Advanced Epithelial Ovarian Cancer, is scheduled for publication on June 3, 2025.

As previously announced, data from the OVATION 2 study will also be reviewed in an oral presentation during the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting on June 3, 2025 in Chicago, Illinois. Premal H. Thaker, M.D., Interim Chief of Gynecologic Oncology, David & Lynn Mutch Distinguished Professor of Obstetrics & Gynecology, Director of Gynecologic Oncology Clinical Research at Washington University School of Medicine, is lead author on the publication and will lead the discussion in the oral presentation at the ASCO (Free ASCO Whitepaper) meeting.

"We are very pleased that the data from our OVATION 2 study will be presented in the highly esteemed peer-reviewed journal Gynecologic Oncology and in an oral presentation at the ASCO (Free ASCO Whitepaper) meeting," said Stacy Lindborg, Ph.D., president and chief executive officer of IMUNON. "Having our data presented in two of the premier global platforms in gynecologic oncology underscores both the critical need to develop new therapies to treat ovarian cancer and the strength and potential of IMUNON’s TheraPlas platform technology."

About the Phase 2 OVATION 2 Study

OVATION 2 evaluated the dosing, safety, efficacy and biological activity of intraperitoneal administration of IMNN-001 in combination with neoadjuvant and adjuvant chemotherapy (NACT) of paclitaxel and carboplatin in patients newly diagnosed with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer. Treatment in the neoadjuvant period is designed to shrink the tumors as much as possible for optimal surgical removal after three cycles of chemotherapy. Following NACT, patients undergo interval debulking surgery, followed by three additional cycles of adjuvant chemotherapy to treat any residual tumor. This open-label study enrolled 112 patients who were randomized 1:1 and evaluated for safety and efficacy to compare NACT plus IMNN-001 versus standard-of-care NACT. In accordance with the study protocol, patients randomized to the IMNN-001 treatment arm could receive up to 17 weekly doses of 100 mg/m2 in addition to NACT. As a Phase 2 study, OVATION 2 was not powered for statistical significance. Additional endpoints included objective response rate, chemotherapy response score and surgical response.

About IMNN-001 Immunotherapy

Designed using IMUNON’s proprietary TheraPlas platform technology, IMNN-001 is an IL-12 DNA plasmid vector encased in a nanoparticle delivery system that enables cell transfection followed by persistent, local secretion of the IL-12 protein. IL-12 is one of the most active cytokines for the induction of potent anticancer immunity acting through the induction of T-lymphocyte and natural killer cell proliferation. IMUNON previously reported positive safety and encouraging Phase 1 results with IMNN-001 administered as monotherapy or as combination therapy in patients with advanced peritoneally metastasized primary or recurrent ovarian cancer and completed a Phase 1b dose-escalation trial (the OVATION 1 Study) of IMNN-001 in combination with carboplatin and paclitaxel in patients with newly diagnosed ovarian cancer. IMUNON previously reported positive results from the recently completed Phase 2 OVATION 2 Study, which assessed IMNN-001 (100 mg/m2 administered intraperitoneally weekly) plus neoadjuvant and adjuvant chemotherapy (NACT) of paclitaxel and carboplatin compared to standard-of-care NACT alone in 112 patients with newly diagnosed advanced ovarian cancer.

About Epithelial Ovarian Cancer

Epithelial ovarian cancer is the sixth deadliest malignancy among women in the U.S. There are approximately 20,000 new cases of ovarian cancer every year and approximately 70% are diagnosed in advanced Stage III/IV. Epithelial ovarian cancer is characterized by dissemination of tumors in the peritoneal cavity with a high risk of recurrence (75%, Stage III/IV) after surgery and chemotherapy. Since the five-year survival rates of patients with Stage III/IV disease at diagnosis are poor (41% and 20%, respectively), there remains a need for a therapy that not only reduces the recurrence rate, but also improves overall survival. The peritoneal cavity of advanced ovarian cancer patients contains the primary tumor environment and is an attractive target for a regional approach to immune modulation.

Financial Results

This compared to cash, cash equivalents and marketable securities of approximately $1.08 billion as of December 31, 2024 The decrease in the balance as of March 31, 2025 was primarily driven by net cash used in operations which was offset by $25.0 million in net proceeds from the sale of common stock shares through at-the-market financings during the quarter.

IDEAYA projects that the $1.05 billion in cash, cash equivalent and marketable securities balance as of March 31, 2025 will be sufficient to fund its planned operations into 2029 based on its current operating plan. We have updated our operating plan costs with further pipeline prioritization, including focusing: 1) the IDE161 clinical program on the combination study with DLL3 TOP1 ADC IDE849, 2) the IDE397 and PRMT5 mechanism clinical combination activities to wholly-owned PRMT5 inhibitor IDE892 (PRMT5MTA), and 3) the clinical dose escalation and expansion data for the IDE397 and Trodelvy combination in MTAP-deletion UC, to be utilized for the MTAP-deletion NSCLC indication clinical expansion activities.
