Efficacy of AB1010 in Patients With Systemic Indolent Mastocytosis

December 8, 2018 updated by: AB Science

Phase IIa, Open-label, Randomized Study of Oral AB1010 in Patients With Systemic Indolent Mastocytosis With Handicap and Not Bearing Activating Point Mutations in the Phosphotransferase Domain of c-Kit Such as the Main Mutation Asp-816-Val (D816V)

This is a 12 weeks study aimed at assessing the safety and efficacy of 2 doses of AB1010 in patients suffering from indolent systemic mastocytosis with handicap.

Description

Inclusion Criteria:

  1. Patients with documented Indolent systemic mastocytosis with handicap (ISMwh) having at least 2 infiltrated* organs (skin and /or bone-marrow and/or internal organ).
  2. Bone-marrow, or skin or internal biopsy-documented mastocytosis and evaluable disease.
  3. The absence of an activating point mutation in the phosphotransferase domain of c-Kit such as D816V c-Kit mutation in at least one of the two infiltrated organs: bone marrow and/or skin and/or other tissue.

  4. Handicap defined as at least one of the following handicaps:

    • a number of flush per day ≥ 1 ,
    • a pruritus score ≥ 9 ,
    • a number of stools per day ≥ 4 ,
    • a Pollakyuria (on a per day basis) ≥ 8 ,
    • a QLQ-C30 score ≥ 83 ,
    • a Hamilton rating scale for depression ≥ 12

Exclusion Criteria:

  1. Performance status > 2 (ECOG).
  2. Inadequate organ function, except if the abnormalities are due to involvement by mast cells
