NCT06194877 | Terminated Phase 1 DMC FDA Drug

• 1 other identifier: BGB-3245-EGFR-001
• Study Type: interventional
• Target: 13
• Locations: 2 countries
• Sites: 5

Brief Summary

The primary objectives of Part 1 of this study are to:

• Assess the safety and tolerability of the combination of BGB-3245 and panitumumab in participants with advanced or metastatic colorectal cancer (CRC) with a known mutation status and tumor harboring an oncogenic mutation of v-Raf murine sarcoma viral oncogene homolog B; B-RAF proto-oncogene, serine/threonine kinase (BRAF), Kirsten rat sarcoma viral oncogene homolog (KRAS), or neuroblastoma RAS viral oncogene homolog (NRAS) with documented disease progression during or after at least 1 line of prior therapy.
• Determine the maximum tolerated dose (MTD) of BGB-3245 in combination with panitumumab and the recommended phase 2 dose (RP2D) of the combination. The primary objective of Part 2 of this study is to determine the objective response rate (ORR) as assessed by initial investigator review using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 with BGB-3245 and panitumumab combination treatment at the RP2D.

Study Arms (3)

Part 1: Dose Finding Part

EXPERIMENTAL

Participants with advanced or metastatic CRC and with known mutation status and tumor harboring an oncogenic mutation of BRAF, KRAS, or NRAS and with documented disease progression by RECIST during or after at least 1 line of prior therapy will be enrolled into 4 planned sequentially run cohorts. Participants will receive escalating doses of BGB-3245 in combination with panitumumab to establish the MTD and RP2D by assessing the safety, tolerability, preliminary antitumor activity, and pharmacokinetics (PK) for the combination of BGB-3245 with panitumumab.

Drug: BGB-3245; Drug: Panitumumab

Part 2: Dose Expansion Part, Group 1

EXPERIMENTAL

Participants with advanced or metastatic CRC that harbors KRAS or NRAS mutations who have been treated and had documented disease progression by RECIST criteria during or after at least 1 line of prior therapy. Participants will receive the RP2D of BGB-3245 in combination with panitumumab to further evaluate the safety, PK, and assess the preliminary antitumor activity of the RP2D of the BGB-3245 and panitumumab combination.

Drug: BGB-3245; Drug: Panitumumab

Part 2: Dose Expansion Part, Group 2

EXPERIMENTAL

Participants with advanced or metastatic pancreatic ductal adenocarcinoma (PDAC) that harbors KRAS mutations who have been treated and had documented disease progression by RECIST criteria during or after at least 1 line of prior therapy. Participants will receive the RP2D of BGB-3245 in combination with panitumumab to further evaluate the safety, PK, and assess the preliminary antitumor activity of the RP2D of the BGB-3245 and panitumumab combination.
