Title:
ACE-Breast-02 Pivotal Phase 3 Study of Ambrx’s ARX788 for the Treatment of HER2 Positive Metastatic Breast Cancer Achieves Positive Results
Published date:
03/01/2023
Excerpt:
Ambrx Biopharma Inc...announced today that it has been informed by its partner, NovoCodex Biopharmaceuticals, Inc. (NovoCodex), that an interim analysis for ACE-Breast-02, a randomized Phase 3 breast cancer clinical trial investigating Ambrx’s ARX788, an anti-HER2 antibody drug conjugate (ADC), has met its pre-specified interim primary efficacy endpoint with statistical significance, demonstrating a greater progression free survival (PFS) benefit compared to the active control.

Excerpt:
ARX788-1711 (NCT03255070) was a phase 1 dose-escalation study of ARX788 monotherapy in pts with advanced solid tumors with HER2 expression….The disease control rate (confirmed complete or partial response + stable disease) was 81.8% and 76.7%, for HER2-pos and HER2-low BC, respectively. Six of 9 pts with confirmed responses had a duration of response greater than 5 months...

PD18-09 ACE-Breast-03: Efficacy and safety of ARX788 in patients with HER2+ metastatic breast cancer previously treated with T-DM1
Published date:
11/22/2022
Excerpt:
ACE-Breast-03 (NCT04829604) is an ongoing global, phase 2, single-arm study evaluating ARX788 in patients with HER2+ mBC...The confirmed ORR was 57.1% (4/7 pts) and an unconfirmed ORR of 71.4% (5/7 pts) as one pt experienced an unconfirmed response with PR after 2 cycles. The disease control rate (DCR) was 100% (7/7 pts)…. In this small cohort of patients previously treated with T-DM1, ARX788 had a manageable AE profile and demonstrated promising clinical activity (confirmed ORR 57%; DCR 100%).

Phase I Trial of a Novel Anti-HER2 Antibody-drug Conjugate, ARX788, for the Treatment of HER2-positive Metastatic Breast Cancer
Published date:
05/26/2022
Excerpt:
At 1.5 mg/kg Q3W, the recommended phase II dose, the objective response rate was 65.5% (19/29, 95% confidence interval [CI], 45.7-82.1), the disease control rate was 100% (95% CI, 81.2-100), and the median progression-free survival was 17.02 months (95% CI, 10.09 to not reached)....ARX788 demonstrated a manageable safety profile with promising preliminary signs of activity in HER2-positive MBC patients who progressed on prior anti-HER2 therapies.

PD8-04: Safety and anti-tumor activity of ARX788 in HER2-positive metastatic breast cancer patients whose disease is resistant/refractory to HER2 targeted agents (trastuzumab, ADCs, TKIs, and bispecific antibodies): ACE-Breast-01 trial results
Published date:
10/09/2021
Excerpt:
Nineteen patients showed clinical response in the 1.5 mg/kg Q3W cohort, with the confirmed objective response rate of 66% (19/29, exact 95% CI, 45.7% to 82.1%), with median duration of response of 14.4 months [95% CI (9.0, NA)]. The disease control rate (CR + PR + SD) among the 29 patients treated was 100%....At the 1.5 mg/kg dose level, ARX788 had robust anti-tumor activity in patients whose disease was resistant/refractory to other HER2 targeted therapies and was generally well tolerated with low systemic toxicity.

Title:
ARX788, a novel anti-HER2 antibody-drug conjugate, shows anti-tumor effects in preclinical models of trastuzumab emtansine-resistant HER2-positive breast cancer and gastric cancer
Published date:
03/31/2020
Excerpt:
ARX788 was effective in T-DM1-resistant in vitro and in vivo models of HER2-positive breast cancer and gastric cancer. ARX788 showed a pronounced growth inhibitory effect on all five HER2-positive cell lines tested, of which two gastric cancer cell lines had acquired resistance to T-DM1. ARX788 evoked more apoptotic events compared to T-DM1. Mice treated with ARX788 survived longer than those treated with T-DM1.
