The purpose of this study is to assess the safety, tolerability, and efficacy of BMS-986158 alone and in combination with either Ruxolitinib or Fedratinib in participants with Dynamic International Prognostic Scoring System (DIPSS)-intermediate or high risk blood cancer. Part 1 consists of BMS-986158 in combination with either Ruxolitinib or Fedratinib and Part 2 consists of BMS-986158 in combination with either Ruxolitinib or Fedratinib and BMS-986158 alone.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Bristol-Myers Squibb (BMY) is the sponsoring company for this trial. BiotechSign currently grades this company F (27/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
