Acrivon (NASDAQ: ACRV) 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 registrational-intent Phase 2b 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. The company reported positive clinical data for ovarian and endometrial cancers in April 2024, and in September 2024 it reported additional positive clinical data for endometrial cancer, including a confirmed overall response rate of 62.5% (95% CI, 30.4 - 86.5) and further validation of its prospective OncoSignature selection of patients predicted sensitive to ACR-368 by showing segregation of responders in OncoSignature-positive versus OncoSignature-negative patients (p = 0.009). The median duration of treatment was not yet reached, but the duration on study was 6 months at the time of the data cut.

In addition to ACR-368, Acrivon is also leveraging its proprietary AP3 precision medicine 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 demonstrated in preclinical studies against benchmark inhibitors. In addition, the company has a preclinical cell cycle program with an undisclosed target.

Acrivon has developed AP3 Interactome, a proprietary, computational analytics platform driven by machine learning for integrated comprehensive analyses across all large, in-house AP3 phosphoproteomic drug profiling data sets to advance its in-house research programs.

Our global team operates out of two leading life science clusters, Watertown, MA and Medicon Village in Lund, Sweden.

Position Overview:

This position will apply technical expertise to support biomarker assays—primarily digital imaging, analysis and associated workflows, data analysis, scripting and LIMS—within our CLIA/CAP framework, and work closely with our biomarker platform team to advance our precision medicines in oncology.

Location:

This position will report to the CLIA Laboratory Director and be based at least 60% in our Watertown, MA facility, with no more than 40% in a home office.

Duties and Responsibilities:

• Execute validated slide scanning and quantitative image analysis protocols for high‑complexity tests, including IHC and multiplex immunofluorescence assays.
• Develop and execute validation plans for equipment and assay procedures including software and electronic workflow.
• Collaborate with cross-functional teams to develop image analysis algorithms, scripts and workflows to support clinical and research assay development.
• Lead all LIMS efforts including configurations, validations, document support and training.
• Provide technical guidance on laboratory automation, data tracking and workflow optimization.
• Assist with biostatistics for validation protocols and result analysis.
• Collaborate with Quality, Regulatory, and IT teams to maintain a compliant, efficient laboratory.
• Participate in proficiency testing and regulatory compliance.
• Adhere to the laboratory's quality control policies, document all quality control activities, instrument and procedural calibrations and maintenance performed.
• Follow the laboratory's established policies and procedures whenever test systems are not within the laboratory's established acceptable levels of performance.
• Be capable of identifying problems that may adversely affect test performance or reporting of test results and either must correct the problems or immediately notify the general supervisor, technical supervisor, or Laboratory Director.
• Document all corrective actions taken when test systems deviate from the laboratory's established performance specifications.
• Work on special projects as assigned by management.

Required Skills/Abilities:

• Minimum of master’s degree in computer science, medical technology, histology, biology, or related field.
• Minimum of 5 years of experience in clinical or research pathology laboratory.
• Expertise in digital pathology platforms including multispectral imaging systems.
• Familiarity with histology and IHC (including both bright field and fluorescence techniques).
• Proficiency in Python, RStudio, HTML and laboratory information systems.
• Familiarity with machine learning/AI applications
• Detail‑oriented, precise, and adept at working in regulated environments.
• Excellent communication, problem-solving, and leadership skills.
• Ability to participate constructively on cross-functional and diverse teams.
• Visual acuity for microscopic examination and computer use.
