Myeloproliferative Neoplasms Clinical Trial

Trametinib in Treating Patients With Relapsed or Refractory Juvenile Myelomonocytic Leukemia

Summary

This phase II trial studies how well trametinib works in treating patients with juvenile myelomonocytic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Full Description

PRIMARY OBJECTIVE:

I. To determine the objective response rate to trametinib in children with recurrent or refractory juvenile myelomonocytic leukemia (JMML).

SECONDARY OBJECTIVES:

I. To further define and describe the toxicities of single agent trametinib in children with recurrent or refractory JMML.

II. To further characterize the pharmacokinetics of trametinib in children with recurrent or refractory JMML.

III. To prospectively evaluate mutant allele burden as a marker of disease activity in JMML.

IV. To measure the rate of complete responses in children with recurrent or refractory JMML.

V. To measure the duration of response among responders.

EXPLORATORY OBJECTIVE:

I. To describe the distribution of JMML diagnostic criteria in children with recurrent or refractory JMML.

OUTLINE:

Patients receive trametinib orally (PO) once daily (QD) on days 1-28 of each cycle. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo a bone marrow aspiration or biopsy at baseline, on day 28 of cycles 1 and 2, at all subsequent odd numbered cycles, and at end of treatment.

After completion of study treatment, patients are followed up annually for up to 5 years.

Biologic (anti-neoplastic agent): at least 7 days must have elapsed since completion of therapy with a biologic agent; for agents that have known adverse events occurring beyond 7 days after administration, this period prior to enrollment must be extended beyond the time during which adverse events are known to occur

Monoclonal antibodies:

At least 30 days after the completion of any type of immunotherapy, e.g. tumor vaccines
At least 3 half-lives must have elapsed since prior therapy that included a monoclonal antibody

Radiotherapy:

>= 2 weeks must have elapsed since local palliative external radiation therapy (XRT) (small port)
>= 6 months must have elapsed if prior craniospinal XRT was received, if >= 50% of the pelvis was irradiated, or if traumatic brain injury (TBI) was received
>= 4 weeks must have elapsed if other substantial bone marrow irradiation was given
Stem cell transplant or rescue without TBI: no evidence of active graft versus (vs.) host disease and >= 3 months must have elapsed since transplant; >= 4 weeks must have elapsed since any donor lymphocyte infusion
