Intervention/exposure

Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Bomedemstat

Experimental: Ph 1/2a PMF: Bomedemstat 0.25 mg/kg/d - In the Phase 1/2a portion of the study, PMF participants received 0.25 mg/kg/d bomedemstat orally every day (qd) for 85 days during the Initial Treatment Period (ITP). Qualifying participants could continue to receive treatment for an additional 85 days during an Additional Treatment Period (ATP) as determined by the investigator. The ATP could repeat indefinitely in participants that continued to derive clinical benefit.

Experimental: Ph 1/2a PPV-MF: Bomedemstat 0.25 mg/kg/d - In the Phase 1/2a portion of the study, PPV-MF participants received 0.25 mg/kg/d bomedemstat orally qd for 85 days during the ITP. Qualifying participants could continue to receive treatment for an additional 85 days during an ATP as determined by the investigator. The ATP could repeat indefinitely in participants that continued to derive clinical benefit.

Experimental: Ph 1/2a PET-MF: Bomedemstat 0.25 mg/kg/d - In the Phase 1/2a portion of the study, PET-MF participants received 0.25 mg/kg/d bomedemstat orally qd for 85 days during the ITP. Qualifying participants could continue to receive treatment for an additional 85 days during an ATP as determined by the investigator. The ATP could repeat indefinitely in participants that continued to derive clinical benefit.

Experimental: Ph 2b PMF: Bomedemstat 0.5 mg/kg/d - In the Phase 2b portion of the study, PMF participants received 0.5 mg/kg/d bomedemstat orally qd for 169 days during the ITP. Qualifying participants could continue to receive treatment for an additional 169 days during an ATP as determined by the investigator. The ATP could repeat indefinitely in participants that continued to derive clinical benefit.

Experimental: Ph 2b PPV-MF: Bomedemstat 0.5 mg/kg/d - In the Phase 2b portion of the study, PPV-MF participants received 0.5 mg/kg/d bomedemstat orally qd for 169 days during the ITP. Qualifying participants could continue to receive treatment for an additional 169 days during an ATP as determined by the investigator. The ATP could repeat indefinitely in participants that continued to derive clinical benefit.

Experimental: Ph 2b PET-MF: Bomedemstat 0.5 mg/kg/d - In the Phase 2b portion of the study, PET-MF participants received 0.5 mg/kg/d bomedemstat orally qd for 169 days during the ITP. Qualifying participants could continue to receive treatment for an additional 169 days during an ATP as determined by the investigator. The ATP could repeat indefinitely in participants that continued to derive clinical benefit.

Experimental: Ph 2b PMF: Bomedemstat 0.6 mg/kg/d - In the Phase 2b portion of the study, PMF participants received 0.6 mg/kg/d bomedemstat orally qd for 169 days during the ITP. Qualifying participants could continue to receive treatment for an additional 169 days during an ATP as determined by the investigator. The ATP could repeat indefinitely in participants that continued to derive clinical benefit.

Experimental: Ph 2b PPV-MF: Bomedemstat 0.6 mg/kg/d - In the Phase 2b portion of the study, PPV-MF participants received 0.6 mg/kg/d bomedemstat orally qd for 169 days during the ITP. Qualifying participants could continue to receive treatment for an additional 169 days during an ATP as determined by the investigator. The ATP could repeat indefinitely in participants that continued to derive clinical benefit.

Experimental: Ph 2b PET-MF: Bomedemstat 0.6 mg/kg/d - In the Phase 2b portion of the study, PET-MF participants received 0.6 mg/kg/d bomedemstat orally qd for 169 days during the ITP. Qualifying participants could continue to receive treatment for an additional 169 days during an ATP as determined by the investigator. The ATP could repeat indefinitely in participants that continued to derive clinical benefit.
