  Purpose

The primary objective of this study is to determine the overall response rate to erlotinib in patients with polycythemia vera (PV). Response rate will be assessed by improvement in the complete blood count, ultrasound of the spleen, and JAK2 molecular status. It is purposed in this study to explore a possible molecular targeting of the driving mechanism of PV.

Primary Outcome Measures:
  • Overall response rate to include Complete Hematological response, Complete molecular response, partial hematological response, and minimal hematological response [ Time Frame: First assessment will be at day 15 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Toxicity, improvement in splenomegaly size, and a decrease of mutant JAK2V617F allele burden, measured by PCR [ Time Frame: First assessment at day 15, subsequent assessments at 28 day intervals ] [ Designated as safety issue: Yes ]

Enrollment: 6
Study Start Date: December 2009
Estimated Study Completion Date: December 2013
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: +JAK2V61F mutation
Patients with MPN diagnoses and polycythemia vera who also have a confirmed JAK2V617F mutation
 Drug: Erlotinib
Erlotinib supplied as tablets; oral dose of erlotinib of 150 mg daily to be continued for 16 weeks. Responders will continue for up to 12 months, non-responders will cease taking erlotinib
Other Names:
  • Tarceva
  • OSI-744

Detailed Description:

This is a phase II open-label study. Patients will be screened for MPN diagnoses and patients with Polycythemia vera proven to have JAK2V617F mutation will be given the option to enroll. Consenting patients will take erlotinib daily for 16 weeks. Blood work and pharmacokinetics will be drawn for serum level monitoring. Doses will be administered according to side effects or held. First assessment will be at day 15 wth subsequent assessments at 28 day intervals. Non-responders will be taken off the study and managed according to standard of care. Patients who do respond will continue taking the therapy for a total of 12 months. Observation will be for a total of 12 months after finishing treatment. In addition to the clinical aspect of this study, there will be correlative studies where molecular response will be checked and its correlation with clinical response.
