Details and patient eligibility
About
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.

Female subjects of childbearing potential and male subjects with a sexual partner of childbearing potential must agree to use a highly effective method of contraception as described in Section 5.4.1.
Treatment Inclusion Criteria (Step 2)

-
Male subjects must agree to use a condom during intercourse for the duration of study therapy as described in Section 5.4.1.
