Brief summary
The purpose of this study was to evaluate the efficacy of derazantinib monotherapy or derazantinib in combination with paclitaxel and ramucirumab in patients with gastric adenocarcinoma (GAC) i.e. with human epidermal growth factor receptor 2 (HER2)-negative adenocarcinoma of the stomach or gastro-esophageal junction harboring fibroblast growth factor receptor 2 (FGFR2) genetic aberrations (GA).
Detailed description
The study comprised two open-label substudies in patients with HER2-negative adenocarcinoma of the stomach or gastro-esophageal junction harboring FGFR2 gene translocations, FGFR2 gene amplifications, or FGFR1-3 mutations. In Substudy 1, GAC patients with specified FGFR GAs, after either first- or second-line treatment, and no approved treatment alternative were treated with derazantinib 300 mg once daily or 200 mg twice daily, with the aim of evaluating the safety, tolerability, and efficacy of derazantinib monotherapy in this patient population. In Substudy 2, GAC patients with specified FGFR GAs after standard first-line treatment, were treated with a derazantinib-paclitaxel-ramucirumab combination with the aim of evaluating the safety, tolerability, and efficacy of the combination therapy and determining the recommended phase 2 dose (RP2D). The study originally planned to include three substudies but was prematurely terminated for administrative reasons before the third substudy (including combination therapy with derazantinib plus atezolizumab) was initiated.
Interventions
Derazantinib was administered orally at a dose of 300 mg once daily as monotherapy in the Substudy 1 (Cohort 1.1).
Derazantinib was administered orally at a dose of 200 mg once daily in combination with paclitaxel and ramucirumab. Paclitaxel was administered intravenously at a dose of 80 mg/m² on days 1, 8, and 15 of a 28-day cycle in combination with ramucirumab. Ramucirumab was administered intravenously at a dose of 8 mg/kg every 2 weeks in combination with paclitaxel.

Recruitment details
From 6 Oct. 2020 to 10 Jun. 2022, 919 patients (pt.) had molecular pre-screening. 66 had clinical screening, and 47 were treated. In Substudy 2, pt. were allocated to 1 of 3 dose levels using a dose escalation scheme: Derazantinib at a dose of 200 mg once daily, 300 mg once daily, or 200 mg twice daily, all in combination with paclitaxel and ramucirumab. However, no pt. received the highest dose, therefore only the 200 and 300 mg once daily dose levels are presented in the results section.
