Brief Summary

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

The purpose of this study is to test the safety and tolerability of 2141-V11 in people who have cancer that does not respond to standard treatment and who have skin lesions (skin tumors) associated with their cancer. The study will also test how the body processes and responds to 2141-V11, and if the study drug has cancer fighting activity in people. The study drug activates a naturally occurring protein called CD40. By activating CD40, cells of the immune system are better able to identify and kill cancer cells.

We are testing if injection of 2141-V11 into metastasis to the skin will be safe and well tolerated, and may result in immune activation in patients with solid tumors that have metastasis to the skin.

Detailed Description

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

This is a Phase 1 open label, dose-escalation study evaluating the safety, pharmacokinetics, pharmacodynamics, immunogenicity, and efficacy of the Fc-engineered variant 2141-V11 in patients with previously treated relapsed or refractory solid tumors and locally advanced or metastatic solid tumors to the skin amenable to intratumoral injection.

There are two parts to the study: a dose-finding stage (Part I), and a dose expansion stage (Part II). Both Part I and Part II of the study will include patients with locally advanced or metastatic cancers of the skin which are not amenable to standard treatment.

A traditional 3 + 3 dose escalation design will be used (Part I). Successive cohorts of participants (3 participants/cohort) will be started on a fixed dose intratumoral injection of 2141V11 at the dose assigned to their cohort. The study drug, 2141-V11, will be dosed once every 3 weeks. The study drug is administered in cycles.

The first group of study participants in Part I will receive the lowest dose of study drug. The next group of study participants will receive the next higher dose. This dosing scheme continues until the maximum tolerated dose is determined. The maximum tolerated dose (MTD) will be defined as 1 dose level below the dose in which DLTs are observed in \>33% of the participants.

Participants in Part II of the study will receive the MTD determined from Part 1 (dose escalation) of the study. Part II participants in the study will also receive two vaccinations (KLH and tetanus) to allow monitoring of their immune function.

Participants in both Part I and II can continue to receive cycles of study drug at their assigned dose if they do not experience progression of disease, a serious adverse event, and the study is ongoing.

* Platelets \> 75,000/mm3
* Hemoglobin \> 8 g/dl
* Creatinine clearance \> 40 ml/min for the dose-escalation phase, \>25 ml/min in dose expansion phase (if safety data from dose escalation indicate this is possible)
* AST/ALT \< 3 x ULN
* Bilirubin \< 1.5 x ULN (except for participants with Gilbert's Syndrome or of non-hepatic origin)
7. Patients must have refractory or relapsed disease and have must have exhausted all standard-of-care therapy for their disease
8. Must be at least 4 weeks since treatment with checkpoint inhibitors or other antibody-based therapy or investigational agents
9. Must be at least 2 weeks since chemotherapy, targeted small molecule therapy, cytokine therapy, or radiation therapy, and be recovered from any clinically significant toxicity experienced during treatment.
