Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will have a dose escalation part (Phase 1b) and a randomized part (Phase 2). In Phase 1b, patients diagnosed with advanced HER2 positive gastric/gastroesophageal adenocarcinoma will be enrolled in a 3 + 3 design dose escalation manner to evaluate the safety, efficacy, PK/PD of AUR103 Calcium when administered in combination with Trastuzumab and CAPOX (capecitabine and oxaliplatin). Phase 2 is a randomization study. The primary objective of the phase 2 study is to assess the efficacy of AUR103 Calcium when administered in combination with Trastuzumab and CAPOX (capecitabine and oxaliplatin). The phase 2 of the study will be conducted after Phase 1b.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study (AUR103-201; BHARAT-2) will be conducted in patients with HER2-positive gastric or gastroesophageal (GE) junction adenocarcinoma, in the first-line setting. In the study Part 1 (Phase 1b), the safety and tolerability of AUR103 calcium will be evaluated in combination with Trastuzumab and CAPOX. In the study part 1 (Phase 1b), there will 3 cohorts; Cohort 1 patients will receive the study drug (AUR103 Calcium) at 200 mg BID dose along with standard doses of trastuzumab, and CAPOX (capecitabie and oxaliplatin), Cohort 2 patients will receive the study drug (AUR103 Calcium) at 300 mg BID dose along with standard doses of trastuzumab, and CAPOX, and Cohort 3 patients will receive the study drug (AUR103 Calcium) at 400 mg BID dose along with standard doses of trastuzumab, and CAPOX.

In the study Part 2 (Phase 2), the efficacy of AUR103 calcium in combination with Trastuzumab and CAPOX will be evaluated in HER2-positive gastric or gastroesophageal junction adenocarcinoma patients. The part 2 (Phase 2) of the study will be a randomized study which will start after part 1 (Phase 1b). In the study part 2 (Phase 2), there will either 1 or 2 treatment arm(s) and one control arm (Trastuzumab + CAPOX). The number treatment arms will be based on the phase 1b data. However, the treatment patients in the Phase 2 will receive the study drug along with Trastuzumab and CAPOX.

Allocation Method

NA

Intervention Model

PARALLEL

The Phase 1 of the study is a single-arm study, which will be conducted in a dose-escalation manner by following 3 + 3 traditional design. The Phase 2 of the study is a randomized study with either two or three groups with parallel study design. The number of groups in the Phase 2 part of the study will be decided based on the safety, PK and/or PD data from Phase 1.
