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 Details 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.

Hide Arm/Group Description

The pre-defined cutpoint for FGFR1 amplification (SISH+) was an average of at least four FGFR1 signals per nucleus (gene copy number) or FGFR1/CEP8 ratio ≥ 2.0.

mRNA in situ hybridization (ISH) was performed on formalin-fixed paraffin embedded (FFPE) tumor tissue using the RNA scope 2.0 assay system. ISH scores were generated and recorded using the following scoring system at 200 × magnification: 0, no staining; 1, one to 3 dots per tumor cell; 2, 4 to 10 dots per tumor cell; 3, more than 10 dots per cell or presence of dot clusters in ≥1% and < 10% tumor cells; 4, ≥ 10% tumor cells with dot clusters as per the RNA scope system scoring guidelines.18 The pre-defined cutpoint for FGFR1 ISH positivity was a score of 3 or 4 per this scoring system.

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.
