WATERTOWN, Mass., Sept. 09, 2024 (GLOBE NEWSWIRE) -- Acrivon Therapeutics, Inc. (“Acrivon” or “Acrivon Therapeutics”) (Nasdaq: ACRV), a clinical stage precision medicine company utilizing its Acrivon Predictive Precision Proteomics (AP3) platform for the discovery, design, and development of drug candidates through a mechanistic match to patients whose disease is predicted sensitive to the specific treatment, today announced that the company will host a virtual investor event to review ACR-368 clinical data that will be presented at a poster presentation at the European Society for Medical Oncology (ESMO) congress on September 14, 2024 in Barcelona, Spain, as well as other R&D updates. The poster presentation will contain updated data from the cohort of patients with endometrial cancer in the ongoing, registrational intent Phase 2b study of ACR-368.

“At our April 2024 R&D event we shared encouraging initial clinical data showing a confirmed response rate of 50% across ovarian and endometrial cancer patients, as well as initial validation of our response-predictive ACR-368 OncoSignature test,” said Peter Blume-Jensen, M.D., Ph.D., chief executive officer, president, and founder of Acrivon. “Enrollment is progressing ahead of schedule for patients with endometrial cancer, a new tumor type that we predicted to be particularly sensitive to ACR-368 with our AP3 platform, and hence we are accelerating this additional interim data disclosure at ESMO. We believe this ongoing registrational intent study for endometrial cancer represents the first potential approval opportunity for ACR-368. We continue enrollment in ovarian and bladder cancer cohorts, and are also enthusiastic about the potential of ACR-368 in other tumor types where it has shown activity, such as squamous cell cancer, and look forward to providing an update on those programs at a future date. In addition to ACR-368, we are also excited to share updates on our clinical candidate, ACR-2316, and the AP3 platform at the webcast on September 14.”

About Acrivon Therapeutics
Acrivon is a clinical stage biopharmaceutical company developing precision oncology medicines that it matches to patients whose tumors are predicted to be sensitive to each specific medicine by utilizing Acrivon’s proprietary proteomics-based patient responder identification platform, Acrivon Predictive Precision Proteomics, or AP3. The AP3 platform is engineered to measure compound-specific effects on the entire tumor cell protein signaling network and drug-induced resistance mechanisms in an unbiased manner. These distinctive capabilities enable AP3’s direct application for drug design optimization for monotherapy activity, the identification of rational drug combinations, and the creation of drug-specific proprietary OncoSignature companion diagnostics that are used to identify the patients most likely to benefit from Acrivon’s drug candidates. Acrivon is currently advancing its lead candidate, ACR-368 (also known as prexasertib), a selective small molecule inhibitor targeting CHK1 and CHK2 in a potentially registrational Phase 2 trial across multiple tumor types. The company has received Fast Track designation from the Food and Drug Administration, or FDA, for the investigation of ACR-368 as monotherapy based on OncoSignature-predicted sensitivity in patients with platinum-resistant ovarian or endometrial cancer. Acrivon’s ACR-368 OncoSignature test, which has not yet obtained regulatory approval, has been extensively evaluated in preclinical studies, including in two separate, blinded, prospectively-designed studies on pretreatment tumor biopsies collected from past third-party Phase 2 trials in patients with ovarian cancer treated with ACR-368.

The FDA has granted Breakthrough Device designation for the ACR-368 OncoSignature assay for the identification of ovarian cancer patients who may benefit from ACR-368 treatment. In addition to ACR-368, Acrivon is also leveraging its proprietary AP3 precision medicine platform for developing its co-crystallography-driven, internally-discovered preclinical stage pipeline programs. These include ACR-2316, a potent, selective WEE1/PKMYT1 inhibitor designed for superior single-agent activity as demonstrated in preclinical studies against benchmark inhibitors, and a cell cycle program with an undisclosed target.
