Clinical Trials

Objective: To determine the Overall Response Rate (ORR) to Imprime PGG + pembrolizumab in subjects with advanced melanoma or metastatic TNBC

Safety: To characterize the safety of Imprime PGG + pembrolizumab given in combination

Hypothesis: Restore (for melanoma) or enhance (for TNBC) sensitivity to checkpoint inhibitors (CPI) by appropriate and effective stimulation of the subject's innate and adaptive immune systems in those subjects who have failed 1st line therapy

The study will incorporate Simon's optimal 2-stage design with sample size fixed at 12 subjects each in Stage 1 for advanced melanoma and for Triple Negative Breast Cancer (TNBC) subjects. The safety criterion of ≤ 4 (or ≤ 33%) subjects with Grade 3/4 adverse events in Cycle 1 within either tumor type must be met in order to proceed to Stage 2. The starting dose is 4 mg/kg for Imprime PGG. In the event there are a total of > 4 (or > 33%) of subjects with Grade 3/4 adverse events in Cycle 1, the dose of Imprime PGG will be reduced to 2 mg/kg, and Stage 1 will be repeated at a dose of 2 mg/kg with an additional cohort of n=12 subjects. For the dose that meets the safety criterion in Stage 1, at least 1 response in melanoma subjects and 2 responses in TNBC subjects amongst the 12 subjects within each tumor type must be observed in order to proceed to Stage 2.

Stage 2 will enroll an additional 17 subjects with melanoma, and 30 subjects with TNBC. For the dose that meets the Stage 1 safety criterion, success will be declared if at least 4 amongst the total of up to 29 subjects with melanoma, and 13 amongst the total of up to 42 subjects with TNBC achieve an objective response.

This phase Ib/II trial studies how well dendritic cell therapy after cryosurgery in combination with pembrolizumab works in treating patients with stage III-IV melanoma that cannot be removed by surgery. Vaccines made from a person's white blood cells mixed with tumor proteins may help the body build an effective immune response to kill tumor cells. Cryosurgery, also known as cryoablation or cryotherapy, kills tumor cells by freezing them. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells. Giving dendritic cell therapy after cryosurgery in combination with pembrolizumab may work better in treating patients with melanoma.

The purpose of this study is to find out more about the side effects of rovalpituzumab tesirine (SC16LD6.5) and what doses of rovalpituzumab tesirine (SC16LD6.5) are safe for people with specific delta-like protein 3-expressing cancers.

This is a multicenter, open-label, first-in-human Phase 1 study evaluating the anti-TIM-3 (T cell immunoglobulin and mucin containing protein-3) antibody TSR-022, as a monotherapy and in combination with an anti-PD-1 antibody, in patients with advanced solid tumors who have limited available treatment options. The study will be conducted in 2 parts: dose escalation and cohort expansion.

This is a Phase 1 multi-center study to evaluate the clinical safety and immune response of ID-LV305 when injected intradermally in patients with advanced cancer. ID-LV305 is a novel immunotherapy agent designed to target dendritic cells and stimulate the body's immune system to fight the spread and growth of cancer for patients whose tumors express the NY-ESO-1 protein. Patients with melanoma, sarcoma, ovarian cancer, or non-small cell lung cancer that express NY-ESO-1 may be considered for the trial. Selected sites will be evaluating ID-LV305 with pembrolizumab for patients with melanoma who have inadequately responded to anti-PD-1 therapy.

The purpose of this study is to evaluate the safety, tolerability and effectiveness of HBI-8000 when combined with a standard dose and regimen of nivolumab.

The purpose of this early phase I pilot trial studies how well vemurafenib, cobimetinib, and atezolizumab work in treating participants with high-risk stage III melanoma. Vemurafenib and cobimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as atezolizumab, may interfere with the ability of tumor cells to grow and spread. Giving vemurafenib, cobimetinib, and atezolizumab may work better in treating high-risk stage III melanoma.

The purpose of the study is to comply with the Pediatric Investigation Plan requirements of Ipilimumab

This pilot clinical trial studies vaccine therapy and resiquimod in treating patients with stage II-IV melanoma that has been removed by surgery. Vaccines made from peptides may help the body build an effective immune response to kill tumor cell tumor cells. Biological therapies, such as resiquimod, may stimulate the immune system in different ways and stop tumor cells from growing. It is not yet known whether Gag:267-274 peptide vaccine and resiquimod are more effective when given together or separately.

This study will be done in 6 parts. In Part A the dose of intravenous (IV) pembrolizumab (MK-3475) will be escalated to find the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) for participants with a histologically or cytologically confirmed diagnosis of any type of carcinoma or melanoma (MEL). Part B of the study will explore the safety, tolerability, and efficacy of the drug in participants with advanced or metastatic MEL and compare every 2 week to every 3 week dosing. Part C of the study will explore the safety, tolerability, and efficacy of the drug in participants with non-small cell lung carcinoma (NSCLC) that is locally advanced or metastatic. Part D of the study will explore the low and high doses of study drug identified in Parts A and B in participants with advanced or metastatic MEL. Part E (closed with Amendment 7) will explore low, medium, and high doses of study drug in combination with standard chemotherapy in participants with locally advanced or metastatic NSCLC. Part F will explore low and high doses of study drug in treatment-naive and previously-treated participants with NSCLC with programmed cell death 1 ligand (PD-L1) gene expression. In Parts D and F and some of Part B participants will be randomized to one dose level. The primary hypotheses are the following: that pembrolizumab has acceptable safety and tolerability; and that pembrolizumab shows a clinically meaningful response rate (RR) or disease-control rate (DCR) in participants with melanoma (ipilimumab-refractory or not), and a clinically meaningful RR in participants with NSCLC, especially a clinically meaningful RR in those participants with either cancer, whose tumors express PD-L1.
