Brief Summary:
A multicenter, open-label, single arm, phase II study investigating the clinical efficacy of Fedratinib and Nivolumab combination in patients with myelofibrosis and resistance or suboptimal response to JAK-inhibitor treatment

Condition or disease Intervention/treatment Phase
Primary Myelofibrosis Secondary Myelofibrosis Drug: Fedratinib Oral Capsule [Inrebic] Drug: Nivolumab Phase 2

Detailed Description:
The FRACTION trial will evaluate the clinical efficacy of Fedratinib and Nivolumab combination therapy in patients with primary and secondary myelofibrosis based on the consensus criteria of the International Working Group for Myelofibrosis Research and treatment (IWG-MRT), extended by the criterion RBC-transfusion independence (RBC-TI).

Official Title: A Phase II Study of Fedratinib and Nivolumab Combination in Patients With Myelofibrosis and Resistance or Suboptimal Response to JAK-inhibitor Treatment
Actual Study Start Date : June 14, 2022
Estimated Primary Completion Date : December 31, 2025
Estimated Study Completion Date : June 30, 2026


Arm Intervention/treatment
Experimental: Experimental

Fedratinib (Cycle 1: Run-in-Phase with 400 mg QD for 4 weeks, Cycle 2-12: 400 mg QD, Dose modifications will be allowed based on observed toxicity to a 300 mg or a 200 mg daily dose) + Nivolumab (Cycle 2-12: 240 mg, i.v., q2w)

Patients will receive study treatment until loss of response, death or study discontinuation for other reasons.

Drug: Fedratinib Oral Capsule [Inrebic]
400 mg once daily p.o. from cycle 1-n, dose adjustment will be made according to the protocol

Drug: Nivolumab
240 mg every 2 weeks i.v. from cycle 2-n




Primary Outcome Measures :
  1. Best response rate within 12 treatment cycles [ Time Frame: 12 months after therapy start. ]
    Best response rate within 12 treatment cycles according to the IWG-MRT criteria (including complete remission, CR, partial remission, PR, clinical improvement, CI, stable disease, SD 1, and red cell transfusion (RCT) independency according to Gale et al.)


Secondary Outcome Measures :
  1. Safety: Incidence and severity of adverse events according to CTC criteria [ Time Frame: From informed consent until 100 days after last study drug ]
    Incidence and severity of adverse events according to CTC criteria

  2. Safety: Timing of adverse events according to CTC criteria [ Time Frame: From informed consent until 100 days after last study drug ]
    Timing of adverse events according to CTC criteria

  3. Safety: Incidence of Laboratory abnormalities [ Time Frame: From informed consent until 100 days after last study drug ]
    Incidence of laboratory abnormalities including timing and relatedness.

  4. Safety: leukemic transformation [ Time Frame: From informed consent until 100 days after last study drug ]
    Cumulative incidence of leukemic transformation

  5. Clinical benefit [ Time Frame: 3.5 years ]
    Proportion of patients with clinical benefit defined as stable disease (SD) plus hematologic improvement or stable disease (SD) plus improvement of MF-associated symptoms

  6. Efficacy: PFS [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 42 months ]
    Progression-free survival

  7. Efficacy: Duration of response [ Time Frame: 3.5 years ]
    Time from first response including RBC-TI, CI, PR and CR (Appendix III) to date of loss of response. Times of patients without loss of response are censored at last tumor assessment.

  8. Efficacy: Overall survival [ Time Frame: 3.5 years ]
    Time from study entry to the last date known to be alive or death. Survival times of patients alive at last follow-up are censored.

  9. Efficacy: Disease burden [ Time Frame: 3.5 years ]
    Change of disease burden assessed by allelic ratio of the respective driver mutation and of high-risk mutations by next-generation sequencing [NGS]
