Acrivon Therapeutics Reports Second Quarter 2024 Financial Results and Business Highlights

WATERTOWN, Mass., Aug. 13, 2024 (GLOBE NEWSWIRE) -- Acrivon Therapeutics, Inc. (“Acrivon” or “Acrivon Therapeutics”) (Nasdaq: ACRV), a clinical stage precision medicine company utilizing its Acrivon Precision Predictive 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 reported financial results for the second quarter ended June 30, 2024 and reviewed business highlights.

“We continue to make significant progress on our mission to deliver on the unique and actionable capabilities of our AP3 platform by rapidly advancing a pipeline of differentiated therapies that address high unmet need cancers,” said Peter Blume-Jensen, M.D., Ph.D., chief executive officer, president, and founder of Acrivon. “We are planning to hold a webcast in September 2024 during the upcoming ESMO conference to update broadly on both clinical lead and pipeline programs as well as on our AP3 platform progress. For our lead asset ACR-368, we expect to share additional clinical data from our ongoing registrational-intent Phase 2b trial at ESMO, building on the initial positive clinical data that we reported in April of this year which showed an overall response rate of 50% in patients with gynecological cancers prospectively predicted sensitive to ACR-368 with our ACR-368 OncoSignature test. We also remain on track to initiate a Phase 1 clinical study with ACR-2316, our potent, selective WEE1/PKMYT1 inhibitor. ACR-2316 has been rationally designed, uniquely enabled by our AP3 platform, for superior single agent activity through robust activation of CDK1, CDK2, and PLK1, resulting in potent, apoptotic tumor cell death as demonstrated in our preclinical studies. Our AP3 platform, which leverages internally generated data and generative AI to deliver unique insights, is broadly applicable across disease areas and modalities and is already being applied to a new cell cycle program with an undisclosed target.”

Recent Highlights

• Presented data from the ongoing, registrational-intent, multicenter Phase 2 trial of ACR-368 in patients with locally advanced or metastatic, recurrent platinum-resistant ovarian cancer or endometrial adenocarcinoma (n=26; 10 OncoSignature-positive and 16 OncoSignature-negative; data as of April 1, 2024)
  • Reported a confirmed overall response rate (ORR), per RECIST 1.1, of 50% observed in the prospective cohort of OncoSignature-positive patients with gynecological cancer who were efficacy evaluable, including 60% ORR in endometrial cancer, a new tumor type predicted to be sensitive to ACR-368 by AP3-enabled indication screening
  • Demonstrated the ability of the AP3-based ACR-368 OncoSignature assay to prospectively predict ovarian and endometrial patients sensitive to ACR-368 monotherapy based on initial data that showed a clear segregation of RECIST responders in the OncoSignature-positive versus OncoSignature-negative arms (p-value = 0.0038)
  • In the OncoSignature-negative arm, initial clinical activity was observed in response to ACR-368 combined with ultra-low dose gemcitabine (ULDG), with 8 out of 16 patients achieving stable disease. ULDG was identified through AP3 profiling as a way to sensitize resistant ovarian cancer cells to ACR-368.
• Discovered ACR-2316 using biological structure-activity relationship (SAR) enabled by AP3 to overcome the limitations of single-target WEE1 and PKMYT1 inhibitors
  • ACR-2316 was designed by AP3 to have optimal properties including strong WEE1 inhibition and balanced PKMYT1 inhibition to elicit potent activation of CDK1, CDK2 and PLK1, resulting in powerful pro-apoptotic mitotic catastrophe and tumor cell death
  • The Phase 1 clinical study of ACR-2316 is on track to be initiated in 4Q 2024
• Executed an oversubscribed $130 million private placement financing at a premium, with support from high caliber new and key existing investors

Anticipated Upcoming Milestones

• Provide pipeline (ACR-368 and ACR-2316), AP3 platform, and corporate updates in 2H 2024, including updated ACR-368 clinical data at the upcoming ESMO conference, where the company will present on September 14, 2024 in the Gynecological Cancers poster session (presentation number P744). The poster will be accessible on our website the same day. The company plans on hosting a live webcast during ESMO to discuss and review the clinical data and provide other pipeline and platform updates.
• Initiate a Phase 1 clinical study of ACR-2316 in 4Q 2024 enriched for tumor types predicted to be sensitive to monotherapy through AP3-based indication finding
• Advance a new potential first-in-class drug discovery program for an undisclosed target towards development candidate nomination in 2025
  
  

Second Quarter 2024 Financial Results



Net loss for the quarter ended June 30, 2024 was $18.8 million compared to a net loss of $13.9 million for the same period in 2023.

Research and development expenses were $15.0 million for the quarter ended June 30, 2024 compared to $10.5 million for the same period in 2023. The difference was primarily due to the continued development of ACR-368, inclusive of progression of the ongoing clinical trial and achieved Akoya milestones, as well as increased personnel costs to support these development activities.

General and administrative expenses were $6.4 million for the quarter ended June 30, 2024 compared to $5.0 million for the same period in 2023. The difference was primarily due to increased personnel costs, inclusive of non-cash stock compensation expense.

As of June 30, 2024, the company had cash, cash equivalents and marketable securities of $220.4 million, which is expected to fund our operating expenses and capital expenditure requirements into the second half of 2026.

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 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.
