Insights
Acrivon shows promising 35% response rate in previously treated endometrial cancer and early tumor shrinkage with second candidate ACR-2316.
Acrivon's Q1 update reveals compelling clinical data for their lead candidate ACR-368 in endometrial cancer patients who progressed after both anti-PD-1 therapy and platinum-based chemotherapy. The 35% confirmed overall response rate in biomarker-positive patients is particularly noteworthy, as it's more than double the response rate these patients achieved on their previous therapy. Even more impressive, patients whose cancer had merely relapsed (rather than being completely refractory) showed a 50% response rate with duration exceeding 10 months - remarkable for this heavily pretreated population.
The company's second clinical candidate, ACR-2316, also shows early promise. Tumor shrinkage of approximately 25% was observed at just the third dose level, well below the projected recommended Phase 2 dose. This suggests potential for even greater efficacy at higher doses. The safety profile appears clean with no dose-limiting toxicities through the first three cohorts.
The appointment of Dr. Mansoor Raza Mirza as CMO significantly strengthens Acrivon's clinical development capabilities. His experience successfully leading registrational trials in gynecological cancers will be invaluable as ACR-368 advances toward potential registration.

The clinical data for ACR-368 represents a potential significant advancement in endometrial cancer treatment. The
The preliminary activity of ACR-2316 at dose level 3 (below the anticipated effective dose) signals promising efficacy potential. Early signs of tumor shrinkage at this stage suggest significant upside as dosing escalates. The confirmation of target engagement through their AP3 platform validates their technological approach.
The appointment of Dr. Mirza as CMO adds considerable credibility to their clinical strategy. His experience with successful registrational trials in gynecological cancers aligns perfectly with Acrivon's lead program.
The company's focus on biomarker-selected patient populations through their AP3 platform demonstrates a precision medicine approach that historically has yielded higher success rates in oncology drug development, potentially de-risking their clinical programs.

WATERTOWN, Mass., May 14, 2025 (GLOBE NEWSWIRE) -- Acrivon Therapeutics, Inc. (“Acrivon” or “Acrivon Therapeutics”) (Nasdaq: ACRV), a clinical stage biotechnology company discovering and developing precision oncology medicines utilizing its proprietary Generative Phosphoproteomics AP3 (Acrivon Predictive Precision Proteomics) platform designed to interpret and quantify compound specific, drug-regulated pathway activity levels inside the intact cell in an unbiased and actionable manner, today reported financial results for the first quarter ended March 31, 2025 and reviewed recent business highlights.
“We made substantial progress in the first quarter in the advancement of our clinical pipeline and the expansion of our Generative Phosphoproteomics AP3 capabilities, as well as strengthening the executive team,” said Peter Blume-Jensen, M.D., Ph.D., chief executive officer, president, and founder of Acrivon. “At our corporate R&D event, we reported positive updated interim data from our ongoing ACR-368 Phase 2b study in endometrial cancer patients with large tumors and aggressive histopathologies – all of whom had progressed after prior platinum-based chemotherapy and anti-PD-1. With a significant unmet need for second-line treatment options and the potential for label expansion through a confirmatory trial in the front-line setting with ACR-368 used as switch maintenance, we remain very excited by the opportunities for this program. For our second clinical-stage asset, ACR-2316, we have observed tumor shrinkage (~
Recent Highlights
- Presented interim data (February 25, 2025) from the ongoing Phase 2b registrational-intent trial of ACR-368 in patients with heavily pretreated endometrial cancer who had all progressed on prior anti-PD-1 and chemotherapy
- Among the 20 OncoSignature-positive (BM+) patients, the confirmed overall response rate (cORR) was
35% , more than double that in the prior line of therapy, and the disease control rate (DCR) was80% - In the BM+ patients that had relapsed after the prior line of therapy, the cORR was
50% , mDOR was not yet reached (>10 months), and DCR was100% - In the BM+ patients with tumors refractory to last prior line of therapy, significant clinical activity was observed with a cORR of
33% and DCR of75%
- Among the 20 OncoSignature-positive (BM+) patients, the confirmed overall response rate (cORR) was
- Provided an overview of the expanded capabilities of the company’s Generative Phosphoproteomics AP3 platform highlighting the growing suite of powerful, internally-developed tools, including the AP3 Data Portal, designed to convert multimodal data into structured data for generative AI analyses, the AP3 Kinase Substrate Relationship Predictor, and the AP3 Interactome. These distinctive capabilities enable the company to go beyond the limitations of traditional drug discovery, as well as current AI-based target-centric drug discovery and rapidly design highly differentiated compounds with desirable pathway effects through intracellular protein network analyses and advance these agents into the clinic for streamlined development.
- Advanced to DL4 in the Phase 1 monotherapy clinical trial of ACR-2316, with encouraging observations at DLs 1-3:
- DL 1, 2, and 3 cleared without safety concerns or dose-limiting toxicities (DLTs) by the safety review committee, and DL4 is now enrolling
- Drug target engagement observed at DL1 and 2 using the company’s clinical mass-spectrometry-based AP3 profiling, with evidence of approximate dose proportionality based on plasma pharmacokinetic analyses

About Acrivon Therapeutics
Acrivon is a clinical stage biopharmaceutical company discovering and developing precision oncology medicines utilizing its proprietary Generative Phosphoproteomics AP3 platform. The platform allows the company to interpret and quantify compound specific, drug-regulated pathway activity levels inside the intact cell in an unbiased manner, yielding terabytes of proprietary data and delivering rapid, actionable insights. The Generative Phosphoproteomics AP3 platform is comprised of a growing suite of powerful, internally-developed tools, including the AP3 Data Portal, converting multimodal data into structured data for generative AI analyses, the AP3 Kinase Substrate Relationship Predictor and the AP3 Interactome. These distinctive capabilities enable the company to go beyond the limitations of traditional drug discovery, as well as current AI-based target-centric drug discovery, and rapidly design highly differentiated compounds with desirable pathway effects through intracellular protein network analyses and advance these agents into the clinic for streamlined development.
Acrivon is currently advancing its lead program, ACR-368 (also known as prexasertib), a selective small molecule inhibitor targeting CHK1 and CHK2 in a potentially registrational Phase 2 trial for endometrial cancer. The company has received Fast Track designation from the Food and Drug Administration, or FDA, for the investigation of ACR-368 as a monotherapy based on OncoSignature-predicted sensitivity in patients with endometrial cancer. The FDA has granted a Breakthrough Device designation for the ACR-368 OncoSignature assay for the identification of patients with endometrial cancer who may benefit from ACR-368 treatment.
In addition to ACR-368, Acrivon is also leveraging its proprietary Generative Phosphoproteomics AP3 platform for developing its co-crystallography-driven, internally discovered pipeline programs. These include ACR-2316, the company’s second clinical stage asset, a novel, potent, selective WEE1/PKMYT1 inhibitor designed for superior single-agent activity through strong activation of not only CDK1 and CDK2, but also of PLK1 to drive pro-apoptotic cell death, as observed in preclinical studies against benchmark inhibitors. The Phase 1 trial of ACR-2316 is advancing with enrollment in the first three dose-escalation cohorts completed. Drug target engagement was observed at DL1 and 2 using the company’s clinical mass-spectrometry-based AP3 profiling, with evidence of approximate dose proportionality based on plasma pharmacokinetic analyses, and initial clinical activity with tumor shrinkage observed at DL3. The company also has a preclinical cell cycle program with an undisclosed target.
