Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A Phase 1 Open-label Dose Escalation Trial of BDB018 in Monotherapy and in Combination with Pembrolizumab in Subjects with Advanced Solid Tumors

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This clinical trial is a study of an experimental drug called BDB018. BDB018 is a next-generation Toll-like receptor (TLR) 7/8 agonist that activates the immune system.

The primary objectives of this study are to evaluate the safety and tolerability of BDB018 in monotherapy and in combination with pembrolizumab (Keytruda) in subjects with unresectable or metastatic solid tumors that have relapsed or are refractory to standard treatment or for which there is no approved therapy.

This is a multi-center, open-label, dose escalation/dose expansion Phase 1 study of BDB018 in monotherapy and in combination with pembrolizumab.

The study will be conducted in two separate but independent parts: a dose escalation part with BDB018 in monotherapy and in combination with pembrolizumab and a dose expansion part of BDB018 in combination with pembrolizumab.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

BDB018 in Monotherapy

A single subject will be enrolled at each dose level in the single agent arm.

Then dosage escalation will follow a traditional 3+3 dose escalation design.

Each successive group of patients will be enrolled at an incrementally higher dosage until the Maximum Tolerable Dose (MTD) or Recommended Phase 2 Dose (RP2D) of single agent BDB018 is reached.

Group Type EXPERIMENTAL

BDB018

Intervention Type DRUG

BDB018 is an immunotherapy agent.

BDB018 in Combination with Pembrolizumab

In the combination arm of the study, a standard 3+3 dose escalation design will be utilized for all dose levels.

When the MTD or RP2D of single agent BDB018 is reached, the first dose level cohort of the combination arm will begin. Once the MTD or RP2D in combination has been determined, approximately twenty additional subjects will be enrolled in the expansion phase of the study.

Group Type EXPERIMENTAL

BDB018

Intervention Type DRUG

BDB018 is an immunotherapy agent.

Pembrolizumab

Intervention Type DRUG

Pembrolizumab is a potent humanized monoclonal antibody with high specificity of binding to the PD 1 receptor. Pembrolizumab has an acceptable preclinical safety profile and is approved as an IV therapy for a variety of advanced malignancies.
