Brief Summary:

This Phase II study consists of 2 parts: 1) pre-screening phase and 2) treatment phase.

The pre-screening phase will investigate the presence of HRAS mutations in subjects with a histologically or cytologically confirmed diagnosis of squamous non-small cell lung cancer (SQ-NSCLC). Subjects may participate in the pre-screening phase at initial diagnosis or following prior lines of therapy for SQ-NSCLC.

The treatment phase will investigate the antitumor activity in terms of ORR of tipifarnib in subjects with locally advanced squamous non-small cell lung cancer (SQ-NSCLC) with HRAS mutations and for whom there is no curative therapy available.

Condition or disease Intervention/treatment Phase
Non Small Cell Lung Cancer Drug: Tipifarnib Phase 2

Detailed Description:

Subject enrolment may proceed with information available on tumor HRAS status previously generated during the pre-screening phase, but all subjects must consent to provide tumor slides (or tumor tissue block) from a prior diagnostic biopsy for a retrospective testing of RAS gene status, including T81C polymorphism, and other potential biomarkers at a central facility.

Tipifarnib will be administered at a starting dose of 600 mg, po, bid daily on days 1-7 and 15-21 of 28-day treatment cycles. In the absence of unmanageable toxicities, subjects may continue to receive tipifarnib treatment for up to 24 months in the absence of disease progression and unmanageable toxicity. Treatment may continue beyond 24 months if there is documented evidence of continued clinical benefit.

Tumor assessments will be performed at screening and approximately every 8 weeks for the first 6 months (cycles 2, 4, 6) and then every 12 weeks (cycles 9, 12, 15, etc.) until disease progression, starting at the end of Cycle 2. Additional tumor assessments may be conducted if deemed necessary by the Investigator or for a confirmation of an objective response. Subjects who discontinue tipifarnib treatment for reasons other than disease progression must continue tumor assessments until disease progression, withdrawal of subject's consent to study procedures or initiation of another anticancer therapy.

Determination of objective tumor response will be performed by the Investigator according to the Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1. Electronic copies of tumor images may be de-identified of subject's personal information at the clinical sites and collected by the Sponsor to undergo an external independent radiological review if the sponsor deems it necessary for the final assessment of treatment efficacy. Subjects with a solitary site of disease who have experienced a response may be considered for surgical resection. Subjects with a best response of a partial response and residual disease after salvage surgery will be eligible to continue on study therapy. Information on the duration of response to the last prior therapy will be collected.

Upon disease progression, subjects will be followed approximately every 12 weeks for survival until either death or 24 months after accrual in the subject's study cohort has been completed, whichever occurs first. Information on subsequent anticancer therapy will be collected.

All subjects will be followed-up for safety during treatment and for approximately 30 additional days after treatment discontinuation (or until immediately before the administration of another anticancer treatment). Additional safety follow up may be conducted if unresolved toxicity is present at the End of Treatment visit.

Experimental: Experimental Arm
Tipifarnib 600 mg, po, bid daily on days 1-7 and 15-21 of 28-day treatment cycles for up to 24 months
Drug: Tipifarnib
Tipifarnib 600 mg will be administered until progression
Other Name: Zarnestra

Primary Outcome Measures :
  1. Overall Response Rate [ Time Frame: From the first dose until progression disease, assessed from the first dose until the first assessment at week 6 from the first dose ]
    To determine the antitumor activity in terms of objective response rate (ORR) of tipifarnib in subjects with locally advanced unresectable or metastatic, relapsed and/or refractory, squamous non-small cell lung cancer (SQ-NSCLC) with HRAS mutations

Secondary Outcome Measures :
  1. Frequency of HRAS mutations [ Time Frame: at the beginning of the study, day -7 to day 0 ]
    As there is a screening phase where HRAS mutations will be analyzed, the second outcome is to determine the frequency (%) of this mutation in the target population of this study

  2. Tolerability as Incidence of Treatment-Emergent Adverse Events of Tipifarnib [ Time Frame: from the first dose of treatment until 30 days after the last dose of treatment ]
    Adverse events will be collected in all the patients in order to now the tolerability of the treatment

Ages Eligible for Study:   Child, Adult, Older Adult
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Subject has a histologically or cytologically confirmed diagnosis of squamous non-small cell lung cancer (SQ-NSCLC) for which there is no curative therapy available.
  2. Subject has relapsed (progressive disease) or is refractory to one or more prior therapies. In the case of therapy received in the adjuvant or neo-adjuvant setting, relapse must have occurred within 12 months to be considered prior therapy. Subject may have received prior immunotherapy.
  3. Subject has a tumor that carries a missense HRAS mutation. HRAS status may have been assessed either in blood, primary tumor tissue, recurrent or metastatic disease.
  4. Subject has consented to provide tumor slides (or tumor tissue blocks) for biomarker evaluation. Before enrolment the site must confirm the availability of the tumor sample. If there is no sample available, the trial chair must be contacted for approval. If enrolment in the treatment portion of the study has taken place based on HRAS mutant status as assessed using a blood sample, tumor tissue must be sent before starting cycle 2 of treatment, and It will be used in part for confirmation of HRAS mutant tumor status. Confirmation of HRAS mutant status in tumor tissue is required for continuation of treatment. If HRAS mutation is not confirmed in tumor but is clearly positive in blood, the trial chair will be contacted for approval and the treatment could be maintained. All treated subjects will be evaluated for safety.

6. At least 2 weeks since the last systemic therapy regimen prior to enrolment. Subjects must have recovered to NCI CTCAE v. 4.03 < Grade 2 from all acute toxicities (excluding Grade 2 toxicities that are not considered a safety risk by the Sponsor and Investigator) or toxicity must be deemed irreversible by the Investigator.

7. At least 2 weeks since last radiotherapy. If radiation was localized to the only site of measurable disease, there must be documentation of disease progression of the irradiated site. Subjects must have recovered from all acute toxicities from radiotherapy. Subjects may be on a daily dose of corticosteroids (≤ 20mg prednisone or equivalent), as part of their management from prior radiotherapy.
