The safety, tolerability, and determination of the maximum tolerated dose (MTD) of the combination therapy were first evaluated for IAH0968 in combination with or without the CAPEOX regimen in unsystematically treated subjects with HER2-expressing advanced/metastatic colorectal or gastric cancers (including adenocarcinomas of the gastro-esophageal junction) or HER2-hypo-expressing advanced/metastatic solid tumors. The efficacy of IAH0968 in combination with the CAPEOX regimen versus trastuzumab in combination with the CAPEOX regimen in subjects with HER2-positive advanced/metastatic gastric cancer, including gastro-esophageal junction adenocarcinoma, was then assessed by progression-free survival (PFS) according to the Research and Evaluation Criteria for the Evaluation of Efficacy in Solid Tumors (RECIST) 1.1.

Phase Ib study: To determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT) and/or Phase II recommended dose (RP2D) of intravenous IAH0968 combined with GC for adult patients with HER2-positive advanced solid tumors who have failed standard treatment. Phase II study: Using the RP2D determined in the Phase Ib study, it is used as the first-line treatment for patients with HER2-positive advanced or metastatic cholangiocarcinoma (BTC) who have not received systemic treatment. According to RECIST 1.1, the effectiveness of IAH0968 combined with GC and placebo combined with GC is compared by objective remission rate (ORR).

Background:

IAH0968 is an afucosylated anti-epidermal growth factor receptor 2 (HER2) monoclonal antibody which improved the activity of antibody-dependent cellular cytotoxicity (ADCC) and superior anti-tumor efficacy.

Methods:

To determine the maximum tolerated dose (MTD) with dose-limiting toxicity (DLT), a single institution, phase Ia/Ib study was undertaken, using 3 + 3 design. The primary endpoints were safety, tolerability and preliminary clinical activity. Eighteen patients were evaluable for safety and fifteen patients were suitable for efficacy analysis. Dose escalations were 6 mg/kg (N = 2), 10 mg/kg (N = 7), 15 mg/kg (N = 5), and tolerable up to 20 mg/kg (N = 4).

Results:

Only one DLT was found at dosage 10 mg/kg, and no MTD was reached. The most common Grade 3 treatment-related adverse events (TRAEs) were hypokalemia (5.6%), supraventricular tachycardia (5.6%), interval extension of QTC (5.6%), and infusion reaction (5.6%). Grade 4 TRAE was arrhythmia (5.6%). No serious TRAE or Grade 5 was reported. 22.2% of patients had a TRAE leading to dose adjustment and 16.7% of patients had a TRAE resulting in discontinuation of IAH0968. After a median follow-up of 9.7 months (range, 3.7 - 22.0), the objective response rate (ORR) was 13.3% (2/15), the disease control rate (DCR) was 53.3% (8/15), and median progression-free survival (mPFS) was 4.2 months (95% CI: 1.4 - 7.7), and the median duration of disease control (DDC) was 6.3 months (95% CI: 2.9–not reached), with 4/15 responses ongoing.

Conclusions:

In HER2-positive heavily pretreated metastatic patients, IAH0968 demonstrated promising clinical activity with durable responses and tolerable safety profiles.

Clinical trial registration:

ClinicalTrials.gov, identifier NCT04934514.
