Study Details

Study Description

Brief Summary

This phase II trial studies how well ponatinib hydrochloride works in treating patients with stage III-IV lung cancer. Ponatinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Condition or Disease	Intervention/Treatment	Phase
Adenocarcinoma of the Lung; Extensive Stage Small Cell Lung Cancer; Limited Stage Small Cell Lung Cancer; Recurrent Non-small Cell Lung Cancer; Recurrent Small Cell Lung Cancer; Stage IIIA Non-small Cell Lung Cancer; Stage IIIB Non-small Cell Lung Cancer; Stage IV Non-small Cell Lung Cancer	Drug: Ponatinib	Phase 2

Detailed Description

This study will look at the safety and effectiveness of the investigational drug ponatinib in lung cancer. The investigators hope that ponatinib will work against tumors that have certain biomarkers. Therefore, the study will pre-screen patients for these certain biomarkers before enrolling them into the main treatment study. Different doses of ponatinib may be tested in this study.

Study Results

Participant Flow

Recruitment Details

This is a biomarker driven clinical trial with prescreening for 4 molecular cohorts based on ISH and SISH positivity- FGFR1 ISH+/SISH+, FGFR1 ISH+/SISH-, FGFR1 ISH-/SISH+, and FGFR1 ISH-/SISH-; with the provision of testing for RET rearrangement in the double negative cohort. From Sep2013 to Nov2017, 171 patient samples were prescreened and resulted in 122 samples that had both SISH and ISH scores reportable. 4 of those patients signed main consent and were enrolled to treatment with ponatinib.

Pre-assignment Detail

Tissue samples from patients were prescreened for markers. 171 samples were prescreened. Of these samples, biomarker results were obtained for 122 samples. Of the patients, from which these samples were derived, 4 patients were then enrolled on the study intervention, allocated to different arms based on their biomarker results. Unfortunately, due to poor tolerability and safety concerns regarding ponatinib after treating the first 4 patients, the trial stopped.

Limitations/Caveats

Due to poor tolerability and safety concerns regarding ponatinib after treating the first few patients, the study did not reach its accrual target (N~70) for the treatment portion of this study and could not confirm or refute the null hypothesis (needed a minimum of 12 patients treated). This study prescreened a more heterogeneous population. As a result, all four patients that were enrolled onto the ponatinib treatment arm had either squamous or poorly differentiated lung cancer.
