This Phase II study will investigate the antitumor activity in terms of ORR of tipifarnib in
subjects with relapsed or refractory PTCL. Up to 30 subjects may be enrolled in the study. A
two-stage study design will be used in order to minimize the number of study subjects
treated if tipifarnib were considered not sufficiently efficacious to grant further
development in this subject population. Tumor response assessments will be conducted
according to IWC and/or mSWAT criteria.
Tipifarnib will be administered po, bid daily for 21 day followed by 1 week of rest in
28-day cycles. In the absence of emerging unmanageable toxicity, subjects may continue
tipifarnib treatment for as long as the investigator considers that the treatment is
providing clinical benefit up to 12 months since the subject's enrolment. Treatment may
continue beyond 12 months upon agreement by the Investigator and Sponsor if there is
documented evidence of sustained clinical benefit.
Tumor assessments will be performed approximately every 8 weeks on cycles 2-6 and at least
once approximately every 12 weeks thereafter (Cycles 9, 12, 15, etc.), and will continue
until disease progression. Subjects who have experienced a complete response may be
considered for transplantation. Upon disease progression, all subjects will be followed
approximately every 12 weeks for survival and the use of subsequent therapy until either
death or 12 months after accrual of the last study subject, whichever occurs first. All
subjects will be followed-up for safety during treatment and up to approximately 30 days (30
+/- 7 days) after treatment discontinuation or until immediately before the initiation of
another anti-cancer therapy, whichever occurs first. Additional follow up may be implemented
until the subject recovers from any emergent treatment related toxicity or the adverse event
is considered irreversible by the investigator.
