Regeneron’s Gene Therapy Study: A Long-Term Look at Safety and Efficacy

Regeneron Pharmaceuticals ((REGN)) announced an update on their ongoing clinical study.

Study Overview: Regeneron Pharmaceuticals is launching a study titled A Long-Term Follow-up Protocol for Participants Treated With Gene Modified T Cells. The study aims to assess the long-term safety and efficacy of gene modified T cell therapy in adults, following Health Authorities’ guidance. This research is significant as it provides critical insights into the durability and safety of gene therapy, a cutting-edge treatment approach.

Intervention/Treatment: The study focuses on participants who have previously received gene modified T cell therapy. It is a non-interventional study, meaning no new treatments are administered. Instead, it involves long-term follow-up to monitor participants’ health outcomes.

Study Design: This observational study follows a cohort model with a prospective time perspective. Participants will undergo regular safety assessments, laboratory evaluations, and complete patient-reported outcome questionnaires to gather comprehensive data on the therapy’s long-term effects.

Study Timeline: The study is set to begin on August 7, 2025, with an estimated completion date yet to be determined. The most recent update was submitted on July 8, 2025. These dates are crucial for tracking the study’s progress and aligning investment strategies accordingly.

Market Implications: This study could influence Regeneron’s stock performance by reinforcing investor confidence in its gene therapy pipeline. As the biotechnology industry increasingly focuses on gene therapies, positive outcomes could enhance Regeneron’s competitive position. Investors should monitor updates closely as the study progresses.

The study is ongoing, with further details available on the ClinicalTrials portal.
