Clinical Trial Summary

This is a single site, open-label, dose de-escalation, Phase 1 study of pegylated interferon alfa-2a administered after alloHCT in subjects with primary or secondary myelofibrosis. Part 1 of the study will assess the rate of dose-limiting toxicities (DLTs) during the DLT evaluation period and identify the Recommended Phase 2 Dose (RP2D). Once the RP2D is identified, 6 additional patients will be enrolled in the expansion cohort.

A washout period of prohibited medications for a period of at least five half-lives or as clinically indicated should occur before the start of treatment. - History of neuropsychiatric disease, autoimmune disease, or pancreatitis. - Presence of active interstitial lung disease or pneumonitis, bronchiolitis obliterans, pulmonary hypertension, ulcerative and hemorrhagic/ischemic colitis, and ophthalmologic disorders.

Outcome

Type Measure Description Time frame Safety issue
Primary Rate of dose-limiting toxicities (DLTs) during the DLT evaluation period To identify the Recommended Phase 2 Dose (RP2D) of pegylated interferon alfa-2a in subjects undergoing allogeneic hematopoietic cell transplantation for primary or secondary myelofibrosis Start of treatment to 86 days after treatment initiation
Secondary Assess the safety of pegylated interferon alfa-2a in the study population. Frequency of adverse events (AEs) and serious adverse events (SAEs) characterized by type, severity (as defined by the NIH CTCAE version 5.0), seriousness, duration, and relationship to study treatment. 3 years
Secondary Assess the tolerability of pegylated interferon alfa-2a in the study population. Frequency of adverse events (AEs) and serious adverse events (SAEs) characterized by type, severity (as defined by the NIH CTCAE version 5.0), seriousness, duration, and relationship to study treatment. 3 years
Secondary Assess the rate of treatment-related mortality in the study population. Rate of treatment-related mortality which is defined as proportion of deaths in patients who have received at least one dose of study therapy, which is attributed to complications from alloHCT or conditioning therapy (in the absence of myelofibrosis relapse) from 30 days after the end of conditioning therapy to one week after the last dose of study therapy. 3 years
Secondary Assess leukemia-free survival (LFS) in the study population. Rate of Leukemia-free survival (LFS) as defined from the day of allogeneic hematopoietic cell transplantation to the time documented disease relapse/progression (date of bone marrow blast count of 20% or greater or date of first peripheral blast count of 20% or greater that was subsequently confirmed to sustain for at least 8 weeks), initiation of non-protocol MF therapy, loss to follow-up, study end, or death from any cause, whichever comes first. 3 years
Secondary Assess the incidence of acute and/or chronic graft versus host disease (GVHD) in the study population Cumulative incidence of Glucksberg grade II, III, and IV acute GVHD and incidence of mild, moderate or severe chronic GVHD per NIH grading criteria. 3 years
Secondary Assess Objective Response Rate (ORR) in the study population. Response rates according to IWG-MRT including, CR, PR, CI, PD, SD, or Relapse. 3 Years
