Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Pembrolizumab
Treatment: Drugs - Belzutifan
Treatment: Drugs - Lenvatinib

Experimental: Arm 1: Pembrolizumab + Belzutifan + Lenvatinib - Participants will receive pembrolizumab 400 mg PLUS belzutifan 120 mg PLUS lenvatinib 20 mg (For HCC: 8 mg \[body weight \<60kg\] or 12 mg \[body weight = 60 kg\]). Pembrolizumab will be administered via intravenous (IV) infusion once every 6 weeks (Q6W) for a maximum of 18 doses (approximately 2 years). Belzutifan and lenvatinib will be administered orally once daily (QD) until progressive disease or discontinuation.

Experimental: Arm 2: Pembrolizumab + Lenvatinib - Participants with IO resistant ESCC will receive pembrolizumab 400 mg PLUS lenvatinib 20 mg. Pembrolizumab will be administered via intravenous (IV) infusion once every 6 weeks (Q6W) for a maximum of 18 doses (approximately 2 years). Lenvatinib will be administered orally once daily (QD) until progressive disease or discontinuation.


Treatment: Drugs: Pembrolizumab
Pembrolizumab 400 mg administered Q6W via IV infusion

Treatment: Drugs: Belzutifan
Belzutifan 120 mg administered QD via oral tablet

Treatment: Drugs: Lenvatinib
Lenvantinib dose for HCC is 8 mg QD for body weight \<60 kg and 12 mg QD for body weight = 60 kg administered via oral capsule. For all other tumors, the lenvatinib dose is 20 mg QD administered via oral capsule
