Sponsor: Mayo Clinic
Collaborator: National Cancer Institute (NCI)
Information provided by: National Cancer Institute (NCI)
ClinicalTrials.gov Identifier: NCT00047190
  Purpose

RATIONALE: Tipifarnib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth.

PURPOSE: Phase II trial to study the effectiveness of tipifarnib in treating patients who have myelofibrosis with myeloid metaplasia.


Condition Intervention Phase
Chronic Myeloproliferative Disorders
Drug: tipifarnib
Phase II

Study Type: Interventional
Study Design: Treatment, Open Label
Official Title: A Phase II Trial of R115777 in Myelofibrosis With Myeloid Metaplasia (MMM)

Study Start Date: August 2002
Detailed Description:

OBJECTIVES:

  • Determine the response rate in patients with myelofibrosis with myeloid metaplasia treated with tipifarnib.
  • Determine the toxicity of this drug in these patients.
  • Determine the effect of this drug on disease-associated anemia, palpable splenomegaly, and hypercatabolic symptoms in these patients.
  • Determine the effect of this drug on the pathologic increase in circulating myeloid progenitors from baseline to after the first course in these patients.
  • Correlate response/relapse in these patients with in vitro myeloid colony sensitivity to this drug.
  • Determine the effect of this drug on bone marrow histologic features (osteosclerosis, reticulin fibrosis, and angiogenesis) in these patients.

OUTLINE: This is a multicenter study.

Patients receive oral tipifarnib twice daily on days 1-21. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months until disease progression and then every 6 months for up to 2 years.

PROJECTED ACCRUAL: A total of 18-35 patients will be accrued for this study within 15 months.
