Nektar Therapeutics stock drops after trial results
Nektar Therapeutics' stock price fell by 8.69% as it hit a 20-day low, reflecting investor concerns following recent trial results.
The decline is attributed to the announcement of topline results from the Phase 2b REZOLVE-AA trial, which showed that while the investigational drug rezpegaldesleukin demonstrated significant efficacy in treating severe alopecia areata, the overall results did not meet the primary endpoint when including all patients. This has raised questions about the drug's future in the market, despite some positive outcomes noted when excluding certain patients.
Investors are closely monitoring Nektar's next steps, including plans to advance rezpegaldesleukin into Phase 3 trials in 2026. The mixed results from the trial may impact investor confidence and the company's ability to secure future funding.
