Trial Outcomes & Findings for Pilot Study of Sonidegib and Buparlisib in Treating Patients With Advanced or Metastatic Basal Cell Carcinoma (NCT NCT02303041)

NCT ID: NCT02303041

Last Updated: 2019-01-29

Results Overview

Response was assessed by the Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria, and reported as overall response rate (ORR), comprised of the sum of complete response (CR) rate and partial response (PR) rate. * Complete Response (CR) = Disappearance of all target lesions * Partial Response (PR) = ≥ 30% decrease in the sum of the longest diameter of target lesions * Overall Response (OR) = CR + PR

SECONDARY outcome

Timeframe: up to 12 weeks

Population: Most participants were not evaluable per protocol.

Response per the Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria was monitored for duration of response (DOR) * Complete Response (CR) = Disappearance of all target lesions * Partial Response (PR) = ≥ 30% decrease in the sum of the longest diameter of target lesions * Overall Response (OR) = CR + PR * Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions * Stable disease (SD) = Small changes that do not meet any of the above criteria

SECONDARY outcome

Timeframe: Baseline to 2 years

Population: The individual samples were not analyzed for the biomarkers due to the overall small sample size.

Immunostaining for the Gli-1; Gli-2; "Patched" (Ptch) ; "Suppressor of Fused" (SuFu); "Smoothened" (Smo)"; and phosphatidylinositol-3-kinase (PI3K) cellular biomarkers were to be contacted at baseline and after 12 weeks of treatment.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: up to 2 years post-treatment

Population: The individual samples were not analyzed for the biomarkers due to the overall small sample size, and thus the correlation of gene expression profile to therapeutic response was not conducted.

The gene expression profiles for Gli-1; Gli-2; "Patched" (Ptch) ; "Suppressor of Fused" (SuFu); "Smoothened" (Smo)"; and phosphatidylinositol-3-kinase (PI3K) were to be correlated to the clinical response to therapeutic therapy.
