About
This is a single arm open-label phase 1 study evaluating the safety and efficacy of escalating doses of CBM588 in combination with nivolumab and ipilimumab. A standard 3+3 dose escalation schema will be used initially to assess the maximum tolerated dose (MTD) followed by a dose expansion of 10 patients at the MTD to further evaluate safety and efficacy.
Full description
This protocol is a phase I open-label, single institution, dose escalation study designed to evaluate the safety, tolerability, and to determine the maximum tolerated dose (MTD) or recommended phase II dose (RP2D) of CBM588 in combination with nivolumab and ipilimumab in patients with previously untreated advanced or metastatic renal cell carcinoma.
The dose escalation phase of the trial will be conducted using a standard 3+3 dose-escalation design to determine the MTD or RP2D. In addition to prespecified dose escalation levels of CBM588, which will be given twice a day continuously, all patients will receive standard of care treatment with nivolumab (3 mg/kg IV every 3 weeks for 4 cycles, followed by 480 IV every 4 weeks) and ipilimumab (1 mg/kg IV q3wks for 4 cycles. At each dose level 3-6 patients will be enrolled based on the decision rule of 3+3 dose-escalation design. Initially, 3 patients are enrolled into the starting dose cohort. If no dose limiting toxicity (DLT) is observed in any of these subjects, the trial proceeds to enroll subjects into the next higher dose cohort. If one subject develops a dose limiting toxicity (DLT) at a specific dose, an additional three subjects are enrolled into that same dose cohort. Development of DLTs in more than 1 of 6 subjects in a specific dose cohort suggests that the MTD has been exceeded, and no further dose escalation is pursued.
Once the MTD is determined, a dose expansion phase will be conducted by enrolling 10 additional patients at the MTD to further evaluate that dose for safety and clinical efficacy endpoints.

Inclusion criteria
Informed Consent and Willingness to Participate
Documented informed consent of the participant and/or legally authorized representative. Agreement to allow the use of archival tissue from diagnostic tumor biopsies Age Criteria, Performance status ECOG ≤ 2 Age ≥ 18 years Nature of Illness and Illness Related Criteria Histologically confirmed renal cell carcinoma with clear cell renal cell carcinoma component or sarcomatoid component. Advanced (not amenable to curative surgery or radiation therapy) or metastatic (AJCC Stage IV) renal cell carcinoma with intermediate- or poor-risk disease by IMDC criteria
No prior systemic therapy for RCC with the following exception:
i. One prior adjuvant or neoadjuvant therapy for completely resectable RCC if recurrence occurred at least 6 months after the last dose of adjuvant or neoadjuvant therapy.
Measurable disease by RECIST 1.1 Fully recovered from the acute toxic effects (except alopecia) to ≤ Grade 1 to prior anti-cancer therapy Clinical Laboratory and Organ Function Criteria Absolute neutrophil count (ANC) ≥ 1500/µL without granulocyte colony-stimulating factor support. White blood cell count ≥ 2500/µL. Platelets ≥ 100,000/µL without transfusion. Hemoglobin ≥ 8 g/dL Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) ≤ 3 x upper limit of normal (ULN). ALP ≤ 5 x ULN with documented bone metastases. Total bilirubin ≤ 1.5 x ULN (for subjects with Gilbert's disease ≤ 3 x ULN). Serum albumin ≥ 2.8 g/dl. (PT)/INR or partial thromboplastin time (PTT) test < 1.3 x the laboratory ULN Serum calculated creatinine clearance ≥ 50mL/min using the Cockcroft-Gault equation: i. Males: (140 - age) x weight (kg)/(serum creatinine [mg/dL] × 72) ii. Females: [(140 - age) x weight (kg)/(serum creatinine [mg/dL] × 72)] × 0.85 Contraception Sexually active fertile subjects and their partners must agree to use medically accepted methods of contraception (e.g., barrier methods, including male condom, female condom, or diaphragm with spermicidal gel) during the course of the study and for 5 months after the last dose of nivolumab for women with childbearing potential, and 7 months after the last dose of nivolumab for men. Female subjects of childbearing potential must not be pregnant at screening. Female subjects are considered to be of childbearing potential unless one of the following criteria is met: documented permanent sterilization (hysterectomy, bilateral salpingectomy, or bilateral oophorectomy) or documented postmenopausal status (defined as 12 months of amenorrhea in a woman > 45 years-of-age in the absence of other biological or physiological causes. In addition, females < 55 years-of-age must have a serum follicle stimulating (FSH) level > 40 mIU/mL to confirm menopause).

Other illnesses or conditions History of allergic reactions attributed to compounds of similar chemical or biologic composition to study agent Active interstitial lung disease (ILD)/pneumonitis or history of ILD/pneumonitis requiring treatment with systemic steroids Known medical condition (e.g., a condition associated with diarrhea or acute diverticulitis) that, in the investigator's opinion, would increase the risk associated with study participation or study drug administration or interfere with the interpretation of safety results.
