Phase I/II Trial Investigating the Safety, Tolerability, Pharmacokinetics, Immune and Clinical Activity of SX-682 in Combination With BinTrafusp Alfa (M7824 or TGF-beta "Trap"/PD-L1) With CV301 TRICOM in Advanced Solid Tumors (STAT)
Background:
Combination immunotherapy techniques are being explored to improve responses and enhance benefits in people with cancer. Researchers want to see if this type of treatment can help people with advanced solid tumors.
Objective:
To find a safe dose of SX-682 in combined treatment with Bintrafusp alfa and BN-CV301 vaccines and to see if this treatment will cause tumors to shrink.
Eligibility:
Adults age 18 and older with metastatic cancer may be eligible for the first part of the trial. Adults age 18 and older with metastatic triple negative breast cancer or p16 negative head and neck squamous cell cancer, and who are not candidates for curative surgery may be eligible for the second part of the trial.
Design:
Participants will be screened under a separate protocol.
Participants may have tumor biopsies. They will have physical exams. Their symptoms and medicines will be reviewed. They will have blood tests. They will have electrocardiograms to evaluate their heart.
Participants will have imaging scans of the chest, abdomen, and pelvis. They may have a procedure where a small tube with a tiny video camera is put into the nose to look at the throat if they have head and neck cancers.
Participants will get bintrafusp alfa through an intravenous catheter. For this, a small tube is put into an arm vein. They will get BN-CV301 vaccines as injections in the arm or thigh. They will take SX-682 by mouth twice a day. They will take the study drugs up to 2 years. They will keep a medicine diary.
Participants will have study visits every 2 weeks. They will have 1 or 2 follow-up visits within 30 days after they stop treatment. Then they will be monitored by phone or email for 2 years.

Detailed Description
Background:
- Combination immunotherapy approaches are being actively explored to further improve responses, enhance clinical benefit, and overcome resistance to Programmed Cell Death Ligand 1 (PD(L)-1) agents in cancer participants.
- Interleukin-8 (IL-8) is a pro-inflammatory chemokine produced by various cell types. Overexpression of IL-8 and/or its receptors C-X-C motif chemokine receptor 1 (CXCR1) and C-X-C motif chemokine receptor 2 (CXCR2), is commonly seen in many human cancers including breast, cervical, melanoma and prostate.
- SX-682 is an oral, small molecule inhibitor of the CXCR1/2 chemokine receptors that are believed involved in myeloid-derived suppressor cells (MDSC)-recruitment to tumor and other pro-tumoral mechanisms.
- Bintrafusp alfa (M7824 or MSB0011359C) is a bifunctional protein composed of the extracellular domain of the Transforming Growth Factor Beta Receptor 2 (TGF-BetaRII) receptor (TGF-Beta 'trap') fused to a human immunoglobulin G1 (IgG1). Preclinical data shows bintrafusp alfa treatment increases T-cell trafficking, antigen specific cluster of differentiation 8 (CD8+) T-cell lysis and natural killer (NK) cell activation.
- CV301 is a poxviral-based vaccine comprised of recombinant Modified vaccinia Ankara (MVA-BN-CV301, prime) and recombinant fowlpox (FPV-CV301, boost). CV301 contains transgenes encoding two (2) tumor-associated antigens (TAA), mucin 1 (MUC1) and carcinoembryonic antigen (CEA), as well as three costimulatory molecules (B7.1, intercellular adhesion molecule 1 (ICAM-1) and lymphocyte function-associated antigen 3 (LFA-3), designated TRICOM). A recent phase 1 clinical trial demonstrated that antigen-specific T cells to MUC1 and CEA, as well as to a cascade antigen, brachyury, were generated in most participants.
- Preclinical studies performed in LTIB with SX-682, M7824 and a CEA-based vaccine showed a significant reduction in tumor growth as well as a significant increase in tumor infiltration with cluster of differentiation 4 (CD4+) and CD8+ T cells.
Objectives:
Arm 1 (Sequential Dose Escalation):
- To evaluate the safety and tolerability of single agent SX-682 given for 2 weeks preceding M7824 and CV301.
- To determine the maximum tolerated dose (MTD) of SX-682 given for 2 weeks preceding M7824 and the CV301 vaccines in participants with advanced or metastatic solid tumors. If the MTD is not reached the study will be focused to describe the safety and tolerability of SX-682 followed by M7824 and CV301 vaccines.
Arm 2 (Combination Dose Escalation):
--To determine the recommended phase 2 dose (RP2D) of SX-682 given concurrently with M7824 and the CV301 vaccines in participants with advanced or metastatic solid tumors. If the MTD is not reached the study will be focused to describe the safety and tolerability of the drug combination.
Arm 3 (Expansion):
- To evaluate preliminary efficacy based on Objective Response Rate (ORR), in each disease separately in two cohorts: Triple Negative Breast Cancer (TNBC) and Human papilloma virus (HPV) negative head and neck squamous cell carcinoma (HNSCC).
Eligibility:
- Age >= 18 years old
- Arms 1 and 2 (Dose-Escalation Cohort): Subjects with cytologically or histologically confirmed locally advanced or metastatic solid tumors.
Arm 3 (Expansion Cohorts):
- Triple Negative Breast Cancer (TNBC): Subjects with cytologically or histologically confirmed locally advanced or metastatic Triple Negative Breast Cancer that has progressed on at least one prior treatment in the advanced or in the metastatic setting.
- Human papilloma virus (HPV) negative head and neck squamous cell carcinoma (HNSCC): Subjects with cytologically or histologically confirmed locally advanced or metastatic, HPV negative head and neck squamous cell cancer (p16 negative for oropharyngeal) that has progressed on at least one prior treatment involving a platinum drug or cetuximab in advanced or in the metastatic setting.
- Prior first line systemic therapy is required unless there is no standard treatment available, the participant cannot tolerate standard first line treatment, or the participant declines standard treatment after appropriate counseling has been provided.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1
- Adequate renal, hepatic, and hematologic function
- Subjects in Arms 1 and 2 may have disease that is measurable or non-measurable but evaluable disease (e.g. present on bone scan, rising tumor markers, non-measurable by Response Evaluation Criteria in Solid Tumors (RECIST) but visible on computed tomography (CT) scan). Participants with third space fluid (for example pleural effusions) as only site of disease will not be eligible. Subjects in Arm 3 must have measurable disease according to RECIST 1.1
Design:
- Arm 1 is a phase I, open-label, 3+3 sequential dose escalation trial with short term, 2-week SX-682 monotherapy, sequentially followed by treatment with M7824 and the CV301 vaccine series in advanced solid tumors (every 2 weeks (Q2W) dosing schedule) for the duration of treatment.
- Arm 2 is a phase I, open-label, 3+3 combination dose escalation trial with concurrently administered SX-682, M7824 and CV301 in advanced solid tumors (Q2W dosing schedule).
- Arm 3 has two expansion cohorts. Following identification of the MTD or recommended phase 2 dose (R2PD) for the combination of SX-682, M7824 and CV301 vaccine given concurrently, disease-specific phase 2 expansion cohorts will open in 1) advanced/metastatic triple negative breast cancer and 2) advanced/metastatic, platinum-refractory HPV negative head and neck squamous cell carcinoma.

- Participants with heart failure (New York Heart Association [NYHA] class III or IV) or cerebrovascular accident within one year or acute myocardial infarction within one year.
- Participants unwilling to accept blood products or blood transfusions as medically indicated. As there is a risk of severe bleeding with M7824, participants must be willing to receive blood transfusions if medically necessary for their own safety
- Any other condition, which would, in the opinion of the Principal Investigator indicated the subject is a poor candidate for the clinical trial or would jeopardize the subject or the integrity of the data obtained.
- Pregnant women are excluded from this study because study drugs potential for teratogenic or abortifacient effects are unknown. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with study drugs, breastfeeding should be discontinued if the mother is treated with study drugs.
