Formycon AG’s FYB206 Study Termination: Market Implications

Formycon AG ((DE:FYB)) announced an update on their ongoing clinical study.

Formycon AG’s recent clinical study aimed to evaluate the efficacy, safety, and immunogenicity of FYB206, a biosimilar to Keytruda, in combination with chemotherapy for patients with metastatic non-squamous non-small cell lung cancer (NSCLC). The study, officially titled A Multicenter, Randomized, Double-blind Trial to Demonstrate Similar Efficacy, Safety, and Immunogenicity of FYB206 (Keytruda Biosimilar Candidate) in Comparison to Keytruda (Pembrolizumab) as an Add-on to Chemotherapy in Treatment-naïve Patients With Metastatic Non-squamous Non-small Cell Lung Cancer, sought to establish FYB206 as a viable alternative to Keytruda.

The intervention tested was FYB206, a biological treatment administered via IV infusion, designed to mimic the effects of Keytruda by aiding the immune system in targeting cancer cells. This biosimilar was assessed alongside chemotherapy to determine its effectiveness as an add-on treatment for NSCLC.

The study was designed as a Phase 3, randomized, parallel, triple-masked trial with the primary purpose of treatment. Participants, investigators, and outcome assessors were blinded to the treatment allocation to ensure unbiased results.

The study commenced on October 3, 2024, with the last update submitted on June 23, 2025. However, the study was terminated, which may impact Formycon AG’s market position and investor sentiment, as the successful development of a Keytruda biosimilar could have positioned the company as a significant player in the oncology market.

The termination of the study might affect Formycon AG’s stock performance, as investors often react to clinical trial outcomes. The competitive landscape in the biosimilar market remains challenging, with established players continuing to dominate.

The study is no longer ongoing, but further details can be accessed on the ClinicalTrials portal.
