A Study of Combination Immunotherapies in Patients Who Have Previously Received Treatment with Immune Checkpoint Inhibitors (QUILT-3.055)

About the Study

Immune checkpoint inhibitors are immunotherapy drugs that allow the immune system to find and destroy cancer cells.

This study will use a combination of immunotherapies in people who's cancer got worse after treatment with a PD-1 or PD-L1 immune checkpoint inhibitor.

Type of Study

This is an open-label study. All participants will receive study drugs and all will know which medications they are receiving. Participants will be assigned to one of five groups based on cancer type and response to prior treatment. 

What the Study Entails

All patients in Groups 1-4 will receive treatment with an immune checkpoint inhibitor plus the novel immunotherapy agent N-803 for up to 17 cycles, where each cycle is six weeks in duration.

Some patients in Groups 1-4 whose cancer grows while on study may roll over into Group 5. Group 5 participants will receive treatment with an immune checkpoint inhibitor, the new immunotherapy agents N-803 and PD-L1 t-haNK cellular therapy for up to an additional 17 cycles, where each cycle is six weeks in duration.

Radiologic evaluation will occur at the end of each treatment cycle.

Treatment will continue for up to 2 years, or until the patient experiences progressive disease or an adverse event keeps the participant from continuing in the study.

This Study is Open To:

Men or women age 18 years or older are eligible to participate if they meet criteria as defined in any one of the following groups:

  • unresectable or metastatic MSI-H or dMMR solid tumors (MMR is caused by mutations in genes that fix DNA damage in cells and common in people with Lynch syndrome) disease progression on or after taking nivolumab as a single agent or in combo with ipilimumab, or disease progression on or after taking pembrolizumab
  • metastatic melanoma disease progression on or after taking pembrolizumab, or taking nivolumab (single-agent), in combo with ipilimumab, or as a subsequent therapy
  • people with the following cancers who had progression or recurrence after treatment with an immune checkpoint inhibitor may also qualify:
    • lung cancer: metastatic squamous or nonsquamous non-small-cell lung carcinoma (NSCLC), metastatic small-cell lung carcinoma (SCLC)
    • locally advanced or metastatic urothelial (urinary) cancer
    • recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) disease
    • metastatic Merkel cell carcinoma (MCC, a type of skin cancer)
    • advanced renal (kidney) cell carcinoma
    • recurrent locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma disease
    • progression, recurrent or metastatic cervical cancer, hepatocellular (liver-related) cancer 
This Study is Not Open To:

Patients may not participate if they have:  

  • Central nervous system (CNS) metastases (contact the study team or visit clinicaltrials.gov to review exceptions)
  • Severe cardiac dysfunction
  • Autoimmune disease requiring active treatment
  • Inflammation of the tissue that surrounds the lung's air sacs, blood vessels and airways, and/or immune mediated pneumonitis (inflammation of lung tissue).
  • HIV-positive
  • Active systemic infection requiring non-oral antibiotic therapy
  • Hepatitis C or Hepatitis B
  • Have had previous malignancies (except non-melanoma skin cancers, in situ bladder cancer, in situ gastric or in situ colon cancers, in situ cervical cancers/dysplasia or breast carcinoma in situ) unless a complete remission was achieved at least 1 year prior to study entry. This exclusion does not apply to patients enrolling in cohort 5.
