Clinical Trial Summary

The purpose of this study is to investigate the safety, pharmacokinetics and preliminary efficacy of combination treatment of ruxolitinib with 5 novel compounds: siremadlin, crizanlizumab, sabatolimab, rineterkib and NIS793 in myelofibrosis (MF) subjects.

Description:

This open-label, multi-center, phase Ib/II platform study design consists of 3 parts. Part 1 is a phase Ib dose escalation and safety run-in for the 5 novel agents in combination with ruxolitinib to assess safety, tolerability and to confirm recommended Phase II dose. Dose escalation cohorts are treated with ruxoltinib + siremadlin or ruxolitinib + rineterkib. Safety run in cohorts are treated with either ruxolitinb + sabatolimab, ruxolitinb + crizanlizumab or ruxolitinib + NIS793 Parts 2 and 3 are phase II selection and expansion respectively, to assess preliminary efficacy of the combination treatments from Part 1 that are evaluated as safe and tolerable. The number of combination treatment arms opening in part 2 will depend on the results of Part 1. In Part 2, an interim analysis was planned to determine if combination treatment (s) can be expanded in Part 3.

In June 2022, Novartis decided to permanently halt the study enrollment in all ongoing parts (part 1 and part 2) and part 3 (expansion) will not be initiated. With protocol amendment 8, an extension treatment phase of 12 cycles is added in Part 1 to allow access to the combination treatment for ongoing subjects deriving clinical benefit. in consideration of the enrollment halt, Parts 2 and 3 objectives will not be pursued and Part 1 objectives are updated accordingly.

The MFSAF v4.0 questionnaire focuses on the 7 core symptoms of MF: fatigue, night sweats, pruritus, abdominal discomfort, pain under the ribs on the left side, early satiety and bone pain. Subjects record symptom severity at it worst for each of the 7 symptoms on an 11-point numeric rating scale, from 0 (absent) to 10 (worst imaginable). The Total Symptom Score (TSS) is the sum of all the scores for all 7 symptoms.

Subjects respond according to the past week recall period, with the exception of the first 5 questions that represent physical functioning and capture the subject's current status. Raw scores are linearly converted to a 0-100 scale. For functional and global health status/QoL higher scores indicate better QoL and level of functioning; for symptom scales, higher scores indicate greater level of symptoms or difficulties.
