Cabozantinib and Pembrolizumab as First Line Therapy in Treating Patients with Cisplatin-Ineligible Metastatic, Locally Advanced, or Unresectable Urothelial Cancer

Status: Active

Description

This phase II trial studies the side effects and best dose of cabozantinib when given together with pembrolizumab and how well it works as first line therapy in treating patients with cisplatin-ineligible urothelial cancer that has spread to nearby tissue or lymph nodes or has spread to other places in the body (locally advanced) or cannot be removed by surgery (unresectable). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, 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 and pembrolizumab may work better in treating patients with cisplatin-ineligible metastatic, locally advanced or unresectable urothelial cancer.

Systemic treatment with radionuclides within 6 weeks before the first dose of study treatment. Subjects with clinically relevant ongoing complications from prior radiation therapy are not eligible
  • Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least 4 weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability

Uncontrolled hypertension needs to be determined based on persistently high blood pressure readings over more than 24 hours and should NOT be based on the blood pressure readings from one clinic visit. Blood pressure readings done at home or by primary care providers are acceptable. If a blood pressure reading on the day of screening is high, but there are documented acceptable (=< 150 mm Hg systolic and =< 100 mm Hg diastolic) blood pressure readings prior to or after the screening visit (with or without the use of anti-hypertensive medications), patient will not be considered to have uncontrolled hypertension * Stroke (including transient ischemic attack [TIA]), myocardial infarction (MI), or other ischemic event, or thromboembolic event (eg, deep venous thrombosis, pulmonary embolism) within 6 months before first dose * Class 3 congestive heart failure

  • Other severe acute or chronic medical conditions including immune colitis, inflammatory bowel disease, immune pneumonitis, pulmonary fibrosis or psychiatric conditions including recent (within the past year) or active suicidal ideation or behavior; or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study
  • Major surgery (e.g., GI surgery, removal or biopsy of brain metastasis) within 8 weeks before first dose of study treatment; complete wound healing from major surgery must have occurred 1 month before first dose and from minor surgery (e.g., simple excision, tooth extraction) at least 10 days before first dose; subjects with clinically relevant ongoing complications from prior surgery are not eligible
  • Corrected QT interval calculated by the Fridericia formula (QTcF) > 500 ms per electrocardiogram (ECG) within 28 days before first dose of study treatment * Note: If a single ECG shows a QTcF with an absolute value > 500 ms, two additional ECGs at intervals of approximately 3 minutes must be performed after the initial ECG, and the average of these three consecutive results for QTcF will be used to determine eligibility

Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, intranasal, inhaled, topical steroids, or local steroid injection) is not considered an exclusion
  • Active autoimmune disease that might deteriorate significantly when receiving an immunostimulatory agent per treating physician’s clinical judgment. Subjects with diabetes type I, vitiligo, psoriasis, or hypo- or hyperthyroid diseases not requiring immunosuppressive treatment are eligible

Trial Objectives and Outline

PRIMARY OBJECTIVE:

I. To evaluate measurable disease overall response rate (ORR).

SECONDARY OBJECTIVES:

I. To evaluate progression-free survival (PFS) at 6 months (PFS6).

II. To evaluate overall survival (OS).

III. To evaluate toxicities associate with the combination treatment.

EXPLORATORY OBJECTIVES:

I. To evaluate molecular markers for pharmacodynamic pathways associated with response.

II. To evaluate ORR and PFS6 using immune specific disease assessment criteria.

OUTLINE:

Patients receives cabozantinib orally (PO) daily on days 1-21 and pembrolizumab intravenously (IV) over 30 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Treatment may continue beyond initial radiographic or clinical disease progression as long as the patient is deriving clinical benefit per physician discretion.

After completion of study treatment, patients are followed up to 6 months.
