Testing the Effectiveness of Two Immunotherapy Drugs (Nivolumab and Ipilimumab) With One Anti-cancer Targeted Drug (Cabozantinib) for Rare Genitourinary Tumors
Recruiting now Phase 2 NCT03866382
Run by National Cancer Institute (NCI) · for 18 and older · All sexes
What this study is about
This phase II trial studies how well cabozantinib works in combination with nivolumab and ipilimumab in treating patients with rare genitourinary (GU) tumors that has spread from where it first started (primary site) to other places in the body. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib, nivolumab, and ipilimumab may work better in treating patients with genitourinary tumors that have no treatment options compared to giving cabozantinib, nivolumab, or ipilimumab alone.
Who can join (things the study team will check)
✅ You may be able to join if…
- Metastatic disease defined as new or progressive lesions on cross-sectional imaging or bone scan. Patients must have at least:
- One measurable site of disease as per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1
- One bone lesion on bone scan (tec99 or sodium fluoride [NaF] PET/CT, CT or MRI) for the bone-only cohort.
- Histologically confirmed diagnosis of one of the following metastatic cohorts:
- Small cell/ neuroendocrine carcinoma of the bladder (Cohort A)- All urothelial carcinomas with any amount of neuroendocrine differentiation (including small cell differentiation) will be included. If the tumor is purely neuroendocrine, metastasis from another site of origin should be clinically excluded
- Adenocarcinoma of the bladder, or urachal adenocarcinoma, or bladder/urethra clear cell adenocarcinoma (Cohort B) - must be pure (per World Health Organization [WHO] definition), (i.e. urothelial carcinoma with glandular differentiation is not considered a pure adenocarcinoma
- Squamous cell carcinoma of the bladder (Cohort C) - must be pure (i.e. urothelial carcinoma with squamous differentiation is not considered a pure squamous cell carcinoma)
- Plasmacytoid urothelial carcinoma (Cohort D) - Tumor should show predominantly > or equal ~ 50% plasmacytoid histology (including all types of discohesive growth, such as tumors with signet-ring and/or rhabdoid features as well)
- Any penile cancer (Cohort E)
- Sarcomatoid renal cell carcinoma (Cohort F) - Tumor should be predominantly sarcomatoid ~ 50% (including rhabdoid differentiation) is also unclassified renal cell carcinomas (RCCs): all (assuming they are high grade with metastasis) malignant angiomyolipomas are allowed
- Other miscellaneous histologic variants of the urothelial carcinoma, such as, but not limited to (Cohort G) : Micropapillary (Tumor should show predominantly > or equal 50% micropapillary architecture), giant cell, lipid-rich, clear cell and nested variants (Tumor should predominantly > or equal 50% show these features), large cell neuroendocrine carcinoma, lymphoepithelioma-like carcinoma and mixed patterns will be considered, as well as small cell neuroendocrine prostate cancer (Only treatment-naïve primary small cell of prostate with any amount of small cell component allowed. Post-treatment small cell prostatic carcinomas are not allowed), Malignant testicular Sertoli or Leydig cell tumors, and papillary and chromophobe RCC
- Note: Translocation positive renal cell carcinoma patients are eligible. However, AREN1721 should be considered before this trial
- Sarcomatoid urothelial carcinoma (Cohort H) - Tumor should show predominantly ~ 50% sarcomatoid differentiation
- Renal medullary carcinoma (Cohort I) - Per World Health Organization (WHO) definition, ideally confirmed with immunostains
- Bone-only metastatic GU tumors (non-prostate) (Cohort J) - All genitourinary histologies, except prostate are eligible
- Renal Collecting Duct Carcinoma (Cohort K) - Per WHO definition (medullary involvement, predominant tubular morphology, desmoplastic stromal reaction, high grade cytology, infiltrative growth pattern, and absence of other renal cell carcinoma subtype or urothelial carcinoma)
- Urethra carcinoma (Cohort L) - May be of any histology but if urothelial carcinoma then must be isolated to the urethra and not have metachronous or synchronous urothelial carcinoma of the bladder
- H\&E slides from diagnostic tumor tissue for retrospective central pathology review
- Patients may have received up to 2 systemic anti-cancer treatments or be treatment naive. Patients with small cell carcinoma should have received a platinum-based combination regimen either as neoadjuvant, adjuvant or first-line treatment). Patients in the bone-only cohort may be urothelial carcinoma histology but must receive standard cisplatin-based chemotherapy (if cisplatin-eligible)
- Age >= 18 years
- Patients must be able to swallow oral formulation of the tablets
- Karnofsky performance status >= 80%
- Absolute neutrophil count (ANC) >= 1,000/mcL
- Platelet count >= 75,000/mcL
- Total bilirubin =< 1.5 x upper limit of normal (ULN). For subjects with known Gilbert's disease or similar syndrome with slow conjugation of bilirubin, total bilirubin =< 3.0 mg/dL
- Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 3.0 x institutional upper limit of normal (ULN) (or =< 5 x ULN for patients with liver metastases or Gilbert's disease)
- Creatinine =< 1.5 x upper limit of normal (ULN) OR creatinine clearance >= 40 mL/min/1.73 m\^2 (calculated using the Chronic Kidney Disease Epidemiology [CKD-EPI] equation or Cockcroft-Gault formula) for patients with creatinine levels above institutional normal
- Hemoglobin >= 9 g/dL (transfusion of packed red blood cells [PRBCs] allowed)
- Serum albumin >= 3.2 g/dL
- Lipase and amylase =< 2.0 x ULN and no radiologic (on baseline anatomical imaging) or clinical evidence of pancreatitis
- Prior treatment with MET or VEGFR inhibitors is allowed. However, prior cabozantinib will not be allowed. Also, patients that have received both prior MET or VEGF and prior PD-1/PD-L1/CTLA-4 (sequentially or in combination) are also not allowed
- No prior treatment with any therapy on the PD-1/PD-L1 axis or anti- CTLA-4/CTLA-4 inhibitors with the exception of patients with "urothelial carcinoma" histology (cohorts D, H, J, L)
- Human immunodeficiency virus (HIV)-positive patients are eligible if on stable dose of highly active antiretroviral therapy (HAART), no clinically significant drug-drug interactions are anticipated with the current HAART regimen, CD4 counts are greater than 350 and viral load is undetectable
- Patients with rheumatoid arthritis and other rheumatologic arthropathies, Sjogren's syndrome and psoriasis controlled with topical medication only and patients with positive serology, such as antinuclear antibodies (ANA), anti-thyroid antibodies etc. are eligible but should be considered for rheumatologic evaluation for the presence of target organ involvement and potential need for systemic treatment
- Patients with vitiligo, endocrine deficiencies including thyroiditis managed with replacement hormones or medications (e.g. thyroiditis managed with propylthiouracil [PTU] or methimazole) including physiologic oral corticosteroids are eligible
- Patients who have evidence of active or acute diverticulitis, intra-abdominal abscess, and gastrointestinal (GI) obstruction, within 12 months are not eligible
- Women of childbearing potential must have a negative pregnancy test =< 7 days prior to registration
- Women of childbearing potential include women who have experienced menarche and who have not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or are not postmenopausal. Post menopause is defined as amenorrhea >= 12 consecutive months. Note: women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, ovarian suppression or any other reversible reason
