NCT05535764

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (6)

  • Assess the safety of pegylated interferon alfa-2a in the study population.

    3 years

  • Assess the tolerability of pegylated interferon alfa-2a in the study population.

    3 years

  • Assess the rate of treatment-related mortality in the study population.

    3 years

  • Assess leukemia-free survival (LFS) in the study population.

    3 years

  • Assess the incidence of acute and/or chronic graft versus host disease (GVHD) in the study population

    3 years

  • +1 more secondary outcomes

Study Arms (1)

Treatment: All Patients

EXPERIMENTAL

A 3+3 dose de-escalation design will be used to determine the recommended phase 2 dose,while ensuring the safety and tolerability of the treatment. In this trial, the dose determined to be the maximum tolerated dose will be the recommended phase 2 dose and will be utilized in the cohort expansion.

Drug: Pegylated interferon alpha2a

Interventions

PegINFa will be given once every 2 weeks by subcutaneous administration in the abdomen or thigh.

Treatment: All Patients

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female subject aged ≥ 18 years.
  • Diagnosis of primary or secondary myelofibrosis.
  • Eligible to undergo a myeloablative or reduced intensity conditioning regimen (MAC or RIC)
  • Eligible to undergo a standard of care bone marrow biopsy with aspirate as part of his or her routine pre-transplant work-up.
  • Peripheral blood stem cell (PBSC) graft
  • /10 HLA matched related or matched unrelated donor
  • ECOG performance status ≤ 2.
  • For female subjects: Negative pregnancy test or evidence of post-menopausal status. The post-menopausal status will be defined as having been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:
  • Women \< 50 years of age:
  • Amenorrheic for ≥ 12 months following cessation of exogenous hormonal treatments; and
  • Luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution; or
  • Underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
  • Women ≥ 50 years of age:
  • Amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments; or
  • Had radiation-induced menopause with last menses \>1 year ago; or
  • +30 more criteria

You may not qualify if:

  • Receiving other investigational agents concurrently
  • Prior systemic anti-cancer therapy or any investigational therapy within five half-lives prior to starting study treatment.
  • Prior radiotherapy within 6 weeks prior to the first dose of study treatment.
  • Major surgery within 6 weeks prior to starting study drug or patients who have not fully recovered from major surgery.
  • The diagnosis of another malignancy within ≤ 2 years before study enrollment, except for those considered to be adequately treated with no evidence of disease or symptoms and/or will not require therapy during the study duration (i.e., basal cell or squamous cell skin cancer, carcinoma in situ of the breast, bladder or of the cervix, or low-grade prostate cancer with Gleason Score ≤ 6).
  • Current evidence of uncontrolled, significant intercurrent illness including, but not limited to, the following conditions:
  • Graft-versus-host disease:
  • Acute or chronic
  • Cardiovascular disorders:
  • Congestive heart failure New York Heart Association Class III or IV, unstable angina pectoris, serious cardiac arrhythmias.
  • Stroke (including transient ischemic attack \[TIA\]), myocardial infarction (MI), or other ischemic events, or thromboembolic event (eg, deep venous thrombosis, pulmonary embolism) within 3 months before the first dose.
  • QTc prolongation defined as a QTcF \> 500 ms.
  • Known congenital long QT.
  • Left ventricular ejection fraction \< 55%.
  • Uncontrolled hypertension defined as ≥ 140/90 as assessed from the mean of three consecutive blood pressure measurements taken over 10 minutes.
  • +9 more criteria
