Summary

The purpose of the study was to find out if the new drug sabatolimab when given in combination with azacitidine and venetoclax, was safe and had beneficial effects in participants with high or very high risk myelodysplastic syndrome (MDS) who were not suitable for treatment with intensive chemotherapy or a stem-cell transplant (HSCT).

Conditions

  • Myelodysplastic Syndrome (MDS)

Interventions

DRUG

sabatolimab

Sabatolimab was administered at a low dose (Safety run-in (Part 1) cohort 1) or a high dose (Safety run-in (Part 1) cohort 2) via i.v. infusion over 30 minutes on Day 8 of every treatment cycle. Cycle = 28 days

DRUG

azacitidine

A standard dose of azacitidine was given subcutaneously or intravenously every day for seven consecutive days on days 1-7 of a confirmed treatment cycle. In keeping with standard clinical practice, the alternative schedules for five consecutive days on days 1-5, followed by a two day break, then two consecutive days on days 8-9 was permitted (alternative schedule).

DRUG

venetoclax

Venetoclax film-coated tablets was administered at a dose of 400 mg orally or corresponding reduced dose for concomitant use with P-gp inhibitors or moderate or strong CYP3A4 inhibitors, once a day, from C1D1 to C1D14 during the treatment cycle. No ramp-up for venetoclax was necessary.
