Exhibit 99.1
Acrivon Therapeutics Announces Positive ACR-368 Phase 2b Endometrial Cancer Clinical Data with EU Expansion to Accelerate Enrollment, Initial ACR-2316 Clinical Data, and ACR-6840, its Next AP3-Enabled Development Candidate, Targeting CDK11
Electronic data capture (EDC) extract from the ongoing ACR-368 registrational-intent Phase 2b monotherapy trial in OncoSignature-positive (BM+) subjects with endometrial cancer (EC) showed 39% overall response rate (ORR) and 44% in subjects with ≤2 prior lines of therapy*
Analysis of data from all-comer subjects with serous subtype and ≤2 prior lines of therapy, a high unmet need population, showed a confirmed ORR (cORR) of 52%, and within BM+ subjects cORR was 67%, consistent with higher BM levels across serous subjects
Arm 3 is enrolling up to 90 subjects with serous subtype and ≤2 prior lines of therapy, without requirement for a tumor biopsy, for treatment with ACR-368 plus ultra-low dose gemcitabine (ULDG) as a tumor sensitizer and enrollment completion expected in fourth quarter 2026
Based on preclinical AP3 data showing strong synergy between ACR-368 and anti-PD-L1, company has submitted a Phase 3 confirmatory protocol to the FDA for ACR-368 plus anti-PD-1 therapy in frontline EC subjects; global trial readiness expected mid-2026
Initial data from Phase 1 dose escalation (N=33) for ACR-2316, a potential first-in-class WEE1/PKMYT1 inhibitor, showed favorable tolerability; two weekly oral dosing regimens (160 mg QD, 3d on/4d off and 240 mg QD, 2d on/5d off) established with a bi-weekly regimen initiated
Tumor shrinkage was observed at ≥120 mg dose level in 9/20 subjects, including a confirmed PR in EC, and unconfirmed PRs in SCLC and sqNSCLC, two tumor types predicted sensitive by AP3, not previously shown sensitive to WEE1 inhibitors in development
ACR-6840, a potential first-in-class AP3-derived oral CDK11 inhibitor, nominated as next preclinical development candidate, with IND submission planned for fourth quarter 2026

WATERTOWN, Massachusetts, January 8, 2026 – Acrivon Therapeutics, Inc. (“Acrivon” or “Acrivon Therapeutics”) (Nasdaq: ACRV), a clinical stage biotechnology company discovering and developing precision medicines utilizing its proprietary Generative Phosphoproteomics AP3 (Acrivon Predictive Precision Proteomics) platform designed to interpret and quantify global compound-specific, drug-regulated effects in the intact cell which is deployed for rational drug design and predictive clinical development, today announced significant progress across its pipeline, including updates regarding the Phase 2 ACR-368 program, initial clinical data from
the ACR-2316 Phase 1 study, and the nomination of Acrivon’s next AP3-enabled preclinical development candidate, ACR-6840, a potential first-in-class, oral CDK11 inhibitor.
“We are pleased with tangible progress accelerating across multiple high-value opportunities,” said Peter Blume-Jensen, M.D., Ph.D., chief executive officer, president, and co-founder of Acrivon. “We are particularly excited by the observation from our ongoing ACR-368 Phase 2 trial that subjects with serous endometrial cancer with up to two prior lines of therapy are showing over 50% confirmed response rate. This provides an attractive opportunity for rapid Arm 3 enrollment without the need for a pretreatment biopsy, both in the US and more than 20 newly selected sites in major EU countries, with anticipated enrollment completion in 2026. Given the high response rate we have observed, and that we intend to give all patients ULDG as a sensitizer for ACR-368, we believe the data from our ongoing study provide for a highly compelling clinical profile in this high unmet need patient population.”
“About a third of all second- and third-line endometrial cancer cases are of serous subtype and represent a challenging patient population,” said Mansoor Raza Mirza, M.D., chief medical officer of Acrivon. “Moreover, incorporating feedback from a Type B meeting in June 2025, we have recently submitted our Phase 3 confirmatory study protocol to the FDA for ACR-368 in combination with anti-PD-1 therapy in frontline endometrial cancer patients, building on the strong synergy observed preclinically between these two agents.”
“We are also very encouraged by the initial clinical data for ACR-2316, including the favorable tolerability profile and observed tumor shrinkage across multiple AP3-prioritized tumor types, including partial responses in heavily pretreated subjects with endometrial cancer, SCLC and squamous NSCLC,” continued Dr. Blume-Jensen. “Finally, we continue to demonstrate the value of our AP3 platform with the nomination from our cell cycle program of ACR-6840, a potential first-in-class CDK11 inhibitor development candidate, with IND submission expected in the fourth quarter of 2026. We believe these achievements represent transformative progress toward delivering meaningful new precision medicine treatment options for cancer patients with high unmet need.”

About Acrivon Therapeutics
Acrivon is a clinical stage biopharmaceutical company discovering and developing precision 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 weekly dosing regimens established. Initial data has shown a favorable tolerability profile limited to transient, mechanism-based hematological adverse events, predominantly neutropenia and initial clinical activity across AP3-selected solid tumor types, including PRs in endometrial cancer, as well as SCLC and sqNSCLC, two tumor types which have not shown sensitivity to other clinical WEE1 or PKMYT1 inhibitors currently in development. In addition, the company is advancing ACR-6840, an internally discovered development candidate targeting CDK11.
