Replimune Group Inc. has received a substantial confidence boost from regulators, with the U.S. Food and Drug Administration accepting the company’s resubmitted application for its RP1 cancer immunotherapy candidate. This regulatory milestone has returned the biotechnology firm to investor focus after a period of uncertainty.
Regulatory Reversal Sparks Market Enthusiasm
Market analysts responded swiftly to the development. Wedbush Securities significantly upgraded its rating on Replimune from “Neutral” to “Outperform.” In a more dramatic move, Wedbush analyst Robert Driscoll elevated the price target from $4.00 to $18.00 – representing a substantial 350% increase. This adjustment reflects renewed confidence in the oncology-focused company’s prospects.
The regulatory landscape had appeared challenging earlier this year. In July 2025, Replimune received a Complete Response Letter from the FDA that raised significant concerns about trial design and data. Even a subsequent meeting in September failed to provide immediate clarity. The agency has now determined that the company’s revised submission, which included additional information, data analyses, and supporting documentation, adequately addresses previous deficiencies.
Key developments at a glance:
* FDA acceptance of RP1 resubmission for advanced melanoma
* Previous Complete Response Letter created regulatory uncertainty
* Wedbush upgrade with 350% higher price target
* FDA decision deadline set for April 10, 2026
* RP1 targets melanoma patients who failed anti-PD-1 therapy
Should investors sell immediately? Or is it worth buying Replimune?
Countdown to Critical FDA Decision
The regulatory agency has established a review timeline that culminates in a final decision by April 10, 2026. During this period, FDA officials will conduct a comprehensive evaluation of the submitted materials.
The RP1 treatment approach utilizes a genetically modified herpes simplex virus designed to selectively destroy tumor cells while triggering a systemic immune response against cancer. For advanced melanoma patients who have not responded to PD-1 inhibitor therapies, this investigational treatment could represent a significant advancement in treatment options.
The biotechnology sector now watches to see whether Replimune can convert this regulatory achievement into commercial success. With the latest regulatory hurdle cleared, the company has positioned itself for potential market advancement in the competitive oncology landscape.
