VX15/2503 in Combination With Ipilimumab or Nivolumab in Patients With Head and Neck Cancer

What this study is about

This phase I trial studies how well anti-semaphorin 4D (SEMA4D) monoclonal antibody VX15/2503 (VX15/2503) with or without ipilimumab and/or nivolumab work in treating patients with stage I-IVA head and neck squamous cell cancer. Monoclonal antibodies, such as VX15/2503, ipilimumab, and nivolumab, may interfere with the ability of tumor cells to grow and spread.

Primary outcome measures

Change in immune profile in the tumor microenvironment

Time frame: Baseline up to 4-8 weeks after surgery

Specimens from surgical resection will be collected under the guidance of the collaborating pathologist and tissue procurement staff at the time of surgery to capture tissue in excess of that needed for clinical staging and diagnostic purposes. Tumor specimens will be fixed in 10% formalin, embedded in paraffin and biomarkers related to activated HNSCC stroma will be assessed via immunohistochemical analysis.

Change in circulating percentage of immune suppressor subsets in peripheral blood

Time frame: Baseline up to 4-8 weeks after surgery

Blood samples will be collected and peripheral blood mononuclear cells will be isolated from these samples and stored in -80°C freezers until analysis. Multi-parameter flow cytometry will be utilized to phenotype immune effector cells. The impact of treatment on the circulating percentage of immune suppressor subsets that may serve as predictors of response to immune checkpoint inhibition. All data will be expressed as the percentage of total circulating peripheral blood cells with each respective phenotype.

Phenotypic shifts in T lymphocyte subsets in peripheral blood

Time frame: Baseline up to 4-8 weeks after surgery

Blood samples will be collected and peripheral blood mononuclear cells will be isolated from these samples and stored in -80°C freezers until analysis. Blood will be analyzed by multi-parameter flow cytometry to identify systemic phenotypic shifts mediated by VX15/2503 in combination with immune checkpoint inhibition.

Who can participate

This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Inclusion criteria

  • Total bilirubin ≤ 1.5 x the upper limit of normal (ULN)
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 x ULN
  • Albumin ≥ 3.0 g/dL
  • Serum creatinine ≤ 1.5 x ULN
  • Calculated creatinine clearance of ≤ 50 mL/min
  • International normalized ratio (INR) ≤ 1.5. Anticoagulation is allowed only with low molecular weight heparin (LMWH). Patient receiving LMW heparin on stable therapeutic dose for more than 2 weeks or with factor Xa level \< 1.1 units/mL (U/mL) are allowed on the trial
  • Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures
  • Ability to understand and willingness to sign a written informed consent document
  • Female subjects of childbearing potential must agree to use adequate contraception (e.g., hormonal or barrier method of birth control; abstinence) for the duration of study treatment and 3 months after completion
  • Male subjects must agree to use adequate contraception (e.g., condoms; abstinence) for the duration of study treatment and 3 months after completion
  • Female subjects of childbearing age must have a negative serum pregnancy test at study entry

Exclusion criteria

  • Poor venous access for study drug administration
  • Nasopharynx cancer, cancer of unknown primary, sinonasal cancer
  • Determined not to be a surgical candidate due to medical co-morbidities
  • Treatment with chronic immunosuppressants (e.g., cyclosporine following transplantation)
  • Prior organ allograft or allogeneic bone marrow transplantation
  • Subjects with any active autoimmune disease or history of known or suspected autoimmune disease except for subjects with vitiligo, resolved childhood asthma/atopy, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll
  • Subjects with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses \> 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease
  • Women who are pregnant or lactating
  • Uncontrolled intercurrent illness including, but not limited to, human immunodeficiency virus (HIV)-positive subjects receiving combination antiretroviral therapy, ongoing or active infection, symptomatic congestive heart failure (New York Heart Association \[NYHA\] class III or IV), unstable angina pectoris, ventricular arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Other medications, or severe acute/chronic medical or psychiatric condition, or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the subject inappropriate for entry into this study
  • Clinical evidence of bleeding diathesis or coagulopathy
  • Prior invasive malignancy (except non-melanomatous skin cancer, low or intermediate risk prostate cancer, or in situ carcinoma fully resected) unless disease free for a minimum of one year
  • Patients that have had prior treatment for HNSCC are not eligible
  • Active bacterial or fungal infections requiring systemic treatment within 7 days of treatment
  • Use of other investigational drugs (drugs not marked for any indication) within 28 days or at least 5 half-lives (whichever is longer) before study drug administration
  • History of severe hypersensitivity reactions to other monoclonal antibodies
  • Non-oncology vaccines within 28 days prior to or after any dose of ipilimumab
  • No archival tissue available pre-study treatment, and repeat biopsy not feasible

Frequently asked questions

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
