Trial Summary

What is the purpose of this trial?

This trial tests a new drug, GS-4528, alone or with an immune therapy in people with advanced solid tumors. The goal is to see if it is safe and to find the best dose. The combination aims to help the immune system fight cancer more effectively.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications, but it does prohibit any anti-cancer therapy within a certain time before starting the study. It's best to discuss your current medications with the trial team to understand any specific requirements.

What data supports the effectiveness of the drug Zimberelimab for solid cancers?

Research on similar treatments, like the bispecific antibody MEDI5752 targeting PD-1 and CTLA4, shows that targeting immune checkpoints can lead to durable responses in various tumor types, suggesting potential effectiveness for Zimberelimab, which also targets immune checkpoints.12345

What makes the drug zimberelimab unique for treating solid cancers?

Zimberelimab is unique because it is a fully human monoclonal antibody that targets the PD-1 receptor, which is involved in preventing the immune system from attacking cancer cells. This mechanism is similar to other PD-1 inhibitors but zimberelimab's fully human design may reduce the risk of immune-related side effects compared to other treatments.678910

Treatment Details

Interventions

  • GS-4528
Trial OverviewThe study is testing GS-4528 alone and combined with an Anti-PD-1 Monoclonal Antibody to see if they're safe and tolerable for treating solid tumors. It aims to find the highest dose patients can take without severe side effects (MTD/MAD) and recommend a Phase 2 dose (RP2D).

Findings from Research

The anti-PD-L1 antibody ZKAB001 demonstrated a manageable safety profile in a Phase I/II study involving 21 patients with localized high-grade osteosarcoma, with the most common side effects being thyroiditis (76.2%) and dermatitis (42.9%).
Preliminary efficacy results indicated a promising 24-month event-free survival rate of 71.4% and a 100% overall survival rate, particularly benefiting patients with PD-L1 positive or MSI-H subtypes.

The phase I trial of MEDI5752, a bispecific antibody that targets both PD-1 and CTLA4, shows that the drug is well tolerated by patients.
Preliminary results indicate that MEDI5752 is active in treating various tumor types, with durable responses observed, suggesting potential effectiveness in cancer therapy.

FS118, a bispecific antibody targeting LAG-3 and PD-L1, was well tolerated in a phase 1 study with 43 patients who had advanced cancer resistant to anti-PD-(L)1 therapy, showing no serious adverse events or dose-limiting toxicities.
The study demonstrated a disease control rate of 46.5%, with a higher rate of 54.8% in patients receiving doses of 1 mg/kg or greater, indicating potential efficacy in this difficult-to-treat population.
