On May 8, 2025 Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, reported that the U.S. Food and Drug Administration (FDA) has approved AVMAPKI FAKZYNJA CO-PACK (avutometinib capsules; defactinib tablets) for the treatment of adult patients with KRAS-mutated recurrent low-grade serous ovarian cancer (LGSOC) who received prior systemic therapy (Press release, Verastem, MAY 8, 2025, View Source [SID1234652771]). AVMAPKI FAKZYNJA CO-PACK is the first and only FDA-approved medicine for this disease. This indication is approved under accelerated approval based on the tumor response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. AVMAPKI plus FAKZYNJA is only commercially available in the U.S. as an oral combination co-pack with the two prescription products, known as "AVMAPKI FAKZYNJA CO-PACK."

"Today’s approval of AVMAPKI FAKZYNJA CO-PACK for patients with KRAS-mutated recurrent low-grade serous ovarian cancer represents not only the first-ever FDA-approved treatment specifically for this rare cancer but also a new day for people living with this disease who have been in desperate need of new treatment options," said Dan Paterson, president and chief executive officer of Verastem Oncology. "We are very proud to bring two innovative medicines in one combination treatment to the LGSOC community. We thank the researchers, patients, and their families participating in our clinical trials, the patient advocacy community, the FDA, and everyone at Verastem for their dedication and commitment to helping us bring AVMAPKI FAKZYNJA CO-PACK to patients in the U.S."

The accelerated approval of AVMAPKI FAKZYNJA CO-PACK is based on the Phase 2 RAMP 201 clinical trial, which evaluated the combination of AVMAPKI and FAKZYNJA in adult patients with measurable KRAS-mutated recurrent LGSOC.

"Low-grade serous ovarian cancer is a rare and highly recurrent cancer with limited effective treatment options. This first-ever FDA approval in this disease was based on the primary analysis of the Phase 2 RAMP 201 trial, in which the combination of avutometinib and defactinib resulted in a significant overall response rate for patients with a KRAS mutation while being generally well tolerated," said Rachel Grisham, M.D., Section Head, Ovarian Cancer at Memorial Sloan Kettering Cancer Center in New York, NY and Global Lead Principal Investigator of GOG-3097/ENGOT-ov81/GTG-UK/RAMP 301. "The approval of avutometinib plus defactinib brings a much-needed therapeutic option to patients and establishes this combination as the new standard of care for women with recurrent low-grade serous ovarian cancer harboring a KRAS mutation. I look forward to progressing the confirmatory Phase 3 trial, RAMP 301, where we look to continue to support the ongoing body of research of this combination in women with and without a KRAS mutation."

"To see our early research in both the FRAME and RAMP 201 trial in recurrent low-grade serous ovarian cancer advance the combination of avutometinib and defactinib to now be the first-ever FDA-approved therapy for this disease is what gives us real hope when treating patients with rare or difficult-to-treat gynecological cancers," said Professor Susana Banerjee, M.B.B.S., M.A., Ph.D., F.R.C.P, Consultant Medical Oncologist at The Royal Marsden NHS Foundation Trust and Team Leader in Women’s Cancers at The Institute of Cancer Research, London and Global Lead Principal Investigator of ENGOTov60/GOG3052 /NCRI/RAMP201. "With this approval, we thank all of the patients and researchers who participated in this trial, and the low-grade serous ovarian cancer community for their contributions to help bring the first FDA-approved treatment for KRAS-mutated recurrent LSGOC and changing the treatment possibilities for RAS/MAPK-pathway-driven cancers. We now need to build on this milestone to bring this new treatment to patients around the world."

Prior to this approval, there were no FDA-approved treatments specifically for KRAS-mutated recurrent LGSOC, a rare and distinct ovarian cancer that differs from high-grade serous ovarian cancer in both its biology and how it responds to treatment.

"One of the most devastating aspects of my LGSOC diagnosis was learning there are no FDA-approved treatments for this rare cancer. While there were some treatment options at the time that I could try, I made it my mission to advocate for research specific to my disease," said Nicole Andrews, chair of the STAAR Low-Grade Serous Ovarian Cancer Foundation. "Today we’re celebrating a milestone with the first-ever FDA-approved treatment option specifically for patients with recurrent LGSOC with a KRAS mutation. The low-grade serous ovarian cancer community is hopeful and excited about the potential benefits of this treatment and the progress toward improving the diagnosis, awareness, and research for LGSOC."

AVMAPKI FAKZYNJA CO-PACK is the first treatment to receive regulatory approval anywhere in the world, specifically for KRAS-mutated recurrent LGSOC. The Company believes AVMAPKI FAKZYNJA CO-PACK is also the first-ever oral, novel/novel combination therapy approved in oncology. Verastem initiated a rolling new drug application (NDA) with the FDA in May 2024 and completed its NDA submission in October 2024. The FDA granted Priority Review, and the approval was received in advance of its Prescription Drug User Fee Act (PDUFA) action date of June 30, 2025. The FDA granted Breakthrough Therapy Designation for the treatment of patients with recurrent LGSOC after one or more prior lines of therapy, including platinum-based chemotherapy, in May 2021. Avutometinib alone or in combination with defactinib was also granted Orphan Drug Designation by the FDA for the treatment of LGSOC.

The AVMAPKI FAKZYNJA CO-PACK is expected to be available for adult patients with KRAS-mutated recurrent LGSOC in the U.S. in one week.

About the VISUALIZE Clinical Trial
The Phase 2B, multicenter, open-label VISUALIZE study (NCT06145048) was designed to evaluate the efficacy and safety of abenacianine for injection in patients undergoing surgery for proven or suspected cancer in the lung. Each of the 89 patients in the study received 0.32mg/kg abenacianine for injection 12 to 36 hours prior to surgery. Following an attempt to identify each tumor using standard surgical techniques, investigators used a commercially available near-infrared (NIR) endoscope to assess the presence of tumor tissue, which was then confirmed by pathology. The primary efficacy endpoint included localization of tumors intraoperatively, surgical margin assessment, and identification of additional cancers or positive lymph nodes that may not have been seen preoperatively.

About Abenacianine for Injection (VGT-309)
Abenacianine for injection is a tumor-targeted fluorescent imaging agent designed to enable a complete solution for optimal tumor visualization with open, minimally invasive and robotic-assisted surgical procedures. Abenacianine for injection is delivered to patients via a short intravenous infusion several hours to several days before surgery. Invented in Professor Matt Bogyo’s Lab at Stanford University School of Medicine, the molecule binds tightly (i.e., covalently) to cathepsins, a family of proteases that are overexpressed across a broad range of solid tumors. This approach, if successful, would provide distinct clinical advantages and position abenacianine for injection as an ideal tumor imaging agent. Abenacianine for injection’s imaging component is the near-infrared (NIR) dye indocyanine green (ICG), which is compatible with all commercially available NIR intraoperative imaging systems that support MIS technologies and is a preferred dye to minimize confounding background autofluorescence.

On May 8, 2025 Lisata Therapeutics, Inc.

"Lisata maintains momentum into 2025 despite a challenging market for small cap healthcare companies as we continue to make notable progress in both our clinical development portfolio and partnering initiatives," stated David J. Mazzo, Ph.D., President and Chief Executive Officer of Lisata. "Overall, our focus remains on evaluating certepetide in multiple clinical and preclinical studies across a variety of solid tumors and non-cancer indications. In January, positive results stemming from both Cohort A of the ASCEND trial as well as the iLSTA trial were presented at ASCO (Free ASCO Whitepaper)-GI and we maintain our forecast of a data-rich period for the remainder of 2025 and into 2026. Heading the list of anticipated results are those from Cohort B of the ASCEND trial as well as results from Catalent’s preclinical evaluation combining certepetide with their SMARTag antibody-drug conjugate (ADC) platform."

Dr. Mazzo added, "Based on concentrated efforts to manage our finances prudently, we now project having operational cash into the third quarter of 2026 as we finalize next steps in certepetide development, based on upcoming conversations with various regulatory agencies including the FDA, TGA and EMA."

Development Portfolio Highlights

Certepetide as a treatment for solid tumors in combination with other anti-cancer agents
Certepetide (formerly LSTA1) is a proprietary, internalizing RGD, or iRGD, (arginylglycylaspartic acid) cyclic peptide designed to activate the C-end rule active transport mechanism in a tumor specific manner, resulting in systemically co-administered anti-cancer agents more efficiently penetrating and accumulating in the tumor. Additionally, certepetide has been shown to modify the tumor microenvironment (TME), diminishing its immunosuppressive nature, enhancing cytotoxic T cell concentration in the TME and inhibiting the metastatic cascade. Lisata and its collaborators have amassed significant non-clinical data demonstrating enhanced efficacy of various existing and emerging anti-cancer therapies, including chemotherapies, immunotherapies, and RNA-based therapeutics in solid tumor models. In addition, to date, certepetide has also demonstrated favorable safety, tolerability, and clinical activity in completed and ongoing clinical trials designed to demonstrate its ability to enhance the effectiveness of standard-of-care (SoC) chemotherapy for pancreatic cancer as well as the combination of chemotherapy and immunotherapy in a variety of solid tumors. Certepetide has been awarded Fast Track designation (U.S.) and Orphan Drug Designation for pancreatic cancer (U.S. and E.U.) as well as Orphan Drug Designation for glioma, osteosarcoma, and cholangiocarcinoma (U.S.). Additionally, certepetide has received Rare Pediatric Disease Designation for osteosarcoma (U.S.). Currently, certepetide is the subject of multiple ongoing or planned preclinical and clinical studies being conducted globally across several solid tumor types in combination with a variety of anti-cancer regimens, including:

•ASCEND: Phase 2b double-blind, randomized (2:1 ratio), placebo-controlled trial evaluating two dosing regimens of certepetide in combination with SoC chemotherapy (gemcitabine/nab-paclitaxel) in patients with previously untreated metastatic pancreatic ductal adenocarcinoma (mPDAC). The trial is being conducted across 25 sites in Australia and New Zealand led by the Australasian Gastro-Intestinal Trials Group (AGITG) and coordinated by the National Health and Medical Research Council Clinical Trial Centre at the University of Sydney. Cohort A, with 95 patients receiving a single intravenous (IV) dose of certepetide 3.2 mg/kg or placebo in combination with SoC, completed enrollment in the third quarter of 2023. Preliminary Cohort A data presented at the 2025 ASCO (Free ASCO Whitepaper)-GI Symposium showed a positive trend in overall survival, including four complete responses in the certepetide-treated group compared to none in the placebo treated group. Data from Cohort B, with 63 patients receiving two IV doses of certepetide 3.2 mg/kg or placebo administered 4 hours apart in combination with SoC, is expected in the coming months with a final analysis of both cohorts available thereafter. Preliminary results from Cohort B data have been accepted for presentation at the ESMO (Free ESMO Whitepaper) Gastrointestinal Cancers Congress being held July 2-5, 2025.

•BOLSTER: Phase 2a double-blind, placebo-controlled, multi-center, randomized trial in the U.S. evaluating certepetide in combination with SoC chemotherapy in first- and second-line cholangiocarcinoma (CCA). The Company achieved complete enrollment in first-line CCA nearly six months ahead of plan, accelerating anticipated topline data readout to mid-2025. Based on this rapid enrollment rate and the pressing need to improve treatment outcomes in patients that have progressed after first-line CCA treatment, a second cohort was added to the BOLSTER trial evaluating certepetide in combination with SoC in subjects with second-line CCA. In September 2024, Lisata announced first patient treated in the second-line CCA cohort and recently decided to stop enrollment at approximately 20 patients to accelerate data read out and optimize capital allocation.

•CENDIFOX: Phase 1b/2a open-label trial in the U.S. evaluating certepetide in combination with neoadjuvant FOLFIRINOX based therapies in pancreatic, colon and appendiceal cancers. In December 2024, the Company announced enrollment completion in all three cohorts. The single-center study, conducted solely at the University of Kansas Cancer Center, was designed with a 3-cycle run-in period to ensure patients met specific criteria before receiving treatment. Of the 66 patients enrolled, 50 patients met the criteria and were treated with certepetide across three cohorts, including 24 with resectable or borderline resectable pancreatic cancer, 15 with high-grade colon or appendiceal cancer and peritoneal metastasis, and 11 with oligometastatic colon cancer. The trial is expected to provide Lisata with valuable pre- and post-treatment tumor tissue data for immune profiling, along with long-term patient outcome information. CENDIFOX data are expected in the coming months; however, given that this is an investigator-initiated study, the exact timing is not in Lisata’s control. The trial is funded by the University of Kansas Cancer Center and Lisata is supplying certepetide.
•Qilu Pharmaceutical, the licensee of certepetide in the Greater China territory, is currently evaluating certepetide in combination with gemcitabine and nab-paclitaxel as a treatment for first-line mPDAC. During the 2023 ASCO (Free ASCO Whitepaper) Annual Meeting, Qilu Pharmaceutical presented an abstract sharing preliminary data from the study which corroborated previously reported findings from the Phase 1b/2a trial of certepetide plus gemcitabine and nab-paclitaxel conducted in Australia in patients with first-line mPDAC. Qilu has completed enrollment in its Phase 2 trial and data are expected in the near future. Progression of Qilu’s certepetide development program into Phase 3 in China will trigger a $10 million milestone payment due to Lisata under the terms of the license agreement with Qilu.

•iLSTA: Phase 1b/2a randomized, single-blind, single-center, safety and pharmacodynamic trial in Australia, funded by WARPNINE Inc., evaluating certepetide in combination with SoC chemotherapy (nab-paclitaxel and gemcitabine) plus SoC immunotherapy (durvalumab) versus SoC alone in patients with locally advanced non-resectable PDAC. An interim analysis of the iLSTA trial, presented at the 2025 ASCO (Free ASCO Whitepaper) GI Symposium, showed preliminary results from the first 17 of the 30 targeted patients, corroborating preclinical data that certepetide enhances the effectiveness of immunotherapy treatment. With 27 of the 30 patients enrolled, enrollment remains on track to be completed by the first half of 2025.
•A Lisata-funded Phase 2a, double-blind, placebo-controlled, randomized, proof-of-concept study evaluating certepetide in combination with SoC temozolomide versus temozolomide alone in patients with newly diagnosed glioblastoma multiforme (GBM) is being conducted across multiple sites in Estonia and Latvia and is planned to also include a site in Lithuania. The study is targeted to enroll 30 patients with a randomization of 2:1 in favor of the certepetide treatment group. Enrollment completion is now expected in 2026.

•FORTIFIDE: A proposed Phase 1b/2a, double-blind, placebo-controlled, three-arm, randomized study in the U.S. evaluating the safety, tolerability, and efficacy of a 4-hour continuous infusion of certepetide in combination with SoC in subjects with first-line mPDAC. As part of this study, Lisata has engaged Haystack Oncology to use its MRD technology to measure circulating tumor DNA levels at multiple timepoints in patients throughout the study as an exploratory endpoint for analyzing the early therapeutic effect of certepetide. Initiation of the study remains on hold as the Company is investigating a potentially faster and more cost-effective alternative to achieve the study’s objective, which may become the preferred strategy.
Preclinically, Lisata has entered into multiple research collaborations, including a sponsored research agreement with the University of Cincinnati to assess certepetide in combination with bevacizumab (a VEGF inhibitor) in a preclinical murine model for the treatment of endometriosis. Lisata is also partnering with Valo Therapeutics (ValoTx) to investigate the benefits of combining certepetide with ValoTx’s platform technology, PeptiCRAd, an oncolytic virus, and a checkpoint inhibitor in a preclinical murine model for the treatment of melanoma.
Additionally, Lisata recently entered into a research license with Catalent, Inc. ("Catalent"), to evaluate the efficacy of certepetide in a preclinical setting with Catalent’s SMARTag ADC dual payload technology platform for the treatment of various difficult-to-treat diseases. Lisata also entered into an exclusive license and collaboration agreement with Kuva Labs, Inc. ("Kuva"), in which Lisata granted Kuva an exclusive license to explore the synergistic potential of certepetide as a targeting and delivery agent for Kuva’s NanoMark imaging technology in solid tumors.
First Quarter 2025 Financial Highlights
For the three months ended March 31, 2025, operating expenses totaled $5.8 million, compared to $6.6 million for the three months ended March 31, 2024, representing a decrease of $0.8 million or 11.4%.
Research and development expenses were approximately $2.6 million for the three months ended March 31, 2025, compared to $3.2 million for the three months ended March 31, 2024, representing a decrease of $0.6 million or 19.7%. This was primarily due to a reduction in clinical research organization expenses and site expenses associated with our Phase 2a proof-of-concept Bolster trial and lower spend on chemistry, manufacturing and controls.
General and administrative expenses were approximately $3.2 million for the three months ended March 31, 2025, compared to $3.4 million for the three months ended March 31, 2024, representing a decrease of approximately $0.1 million or 3.4%. This was primarily due to one-off settlement costs in the prior year partially offset by an increase in consulting expenses and severance costs in the current year.
Overall, net losses were $4.7 million for the three months ended March 31, 2025, compared to $5.4 million for the three months ended March 31, 2024.

Balance Sheet Highlights

As of March 31, 2025, Lisata had cash, cash equivalents, and marketable securities of approximately $25.8 million. Based on its existing and planned activities, the Company believes available funds will support current operations into the third quarter of 2026.

"Werewolf continues to build on our promising data and progress across our clinical-stage programs," said Daniel J. Hicklin, Ph.D., President and Chief Executive Officer of Werewolf. "We remain on track in our Phase 1/1b clinical trial evaluating WTX-124 to share interim data and meet with the FDA to discuss potential registrational pathways in the second half of this year. Additionally, in recognition of Skin Cancer Awareness month, Werewolf is launching an educational campaign in May to highlight the differentiation of Werewolf’s conditionally activated therapeutics and patient experiences to date in the WTX-124 clinical trial. I am also pleased to report that we recently initiated a Phase 1b/2 clinical trial of WTX-330 to explore antitumor activity and optimize the exposure of our IL-12 INDUKINE molecule in the tumor microenvironment. Finally, Werewolf has been making significant progress towards nominating its first INDUCER T cell engager development candidate in the second quarter of 2025, with preclinical data demonstrating that PREDATOR masking technology successfully silenced peripheral activity and prevented cytokine release. We believe that our proprietary PREDATOR masking and targeting technology distinctly positions us to build a robust pipeline of T cell engagers with potentially best-in-class potency and safety profiles, filling a gap in the current immuno-oncology landscape."
