Primary results from JUPITER, a phase 2 basket trial of combination therapy with trastuzumab and pertuzumab in patients with HER2-amplified solid tumors.
Published date:
05/26/2022
Excerpt:
Between April 2019 and June 2020, 42 pts were consented, and 40 pts were treated. Median age was 62 (range, 21-86) and 60% were females. The most common diagnosis was biliary tract cancer (20%), followed by salivary ductal carcinoma (12.5%) and endometrial cancer (12.5%). At data cutoff (1 Sep 2021), ORR by BICR was 22.5% (95%CI: 10.8%-38.5%). ORR assessed by the investigator was 25% (95%CI: 12.7%-41.2%). Combination therapy with trastuzumab and pertuzumab was well tolerated and showed promising efficacy for the patients with HER2-amplified solid tumors determined by NGS.
