Secondary Outcome Measures :
- Best overall objective response rate [ Time Frame: up to 2 years from the start of treatment ]Best overall objective response rate, defined as Partial Response (PR) and Complete Response (CR) per RECIST 1.1.
- Progression Free Survival (PFS) [ Time Frame: up to 2 years from the start of treatment or to time of disease progression ]PFS, defined as the time from start of study drug administration to the date of the first documentation of disease progression or death from any cause, whichever occurs first.
- Overall Survival (OS) [ Time Frame: up to 2 years from the start of treatment or to time of death ]OS, defined as the time from start of study drug administration to date of death from any cause.
- Duration of brain metastasis response [ Time Frame: up to 2 years from the start of treatment ]Duration of brain metastasis response, defined as the time from response to the time of the first documentation of intracranial disease progression.
- Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of melanoma or RCC and untreated metastatic brain disease will be enrolled in this study.
Male participants: A male participant must agree to use a contraception as detailed in the protocol during the treatment period and for at least 120 days after the last dose of study treatment and refrain from donating sperm during this period.
Female participants: A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:
- Not a woman of childbearing potential (WOCBP) OR
- A WOCBP who agrees to follow the contraceptive guidance per protocol during the treatment period and for at least 120 days after the last dose of study treatment.
- The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.
- Have histologic or cytologic confirmation from any body site of metastatic melanoma irrespective of BRAF mutation status or renal cell carcinoma irrespective of histologic subtype.
- Patients who have had prior resection or biopsy of a CNS and/or extracranial metastasis will be required to provide a formalin-fixed, paraffin embedded (FFPE) specimen from tumor taken at the time of surgery, if available. Fresh biopsies of a metastatic lesion should be performed if clinically able.
Note: Participants are not required to have new or repeat brain metastasis biopsies for enrollment on the trial.
Note: For those who have never had CNS brain metastasis biopsies, tissue of an accessible extracranial lesion will be obtained pre-treatment, unless deemed not possible by the treating physician and upon discussion with PI. In this case, archival extracranial metastatic tissue will be suitable.
- Have at least one brain metastasis that is at least 5 mm AND twice the MRI slice thickness, but less than or equal to 3 cm, which is asymptomatic, has not been previously radiated, and is not requiring immediate local therapy or steroids. Lesions situated in a previously irradiated area are considered allowed if measurable per the aforementioned criteria and if progression has been demonstrated. Patients with any lesion(s) >3 cm can be enrolled provided the following: (1) the lesion must receive local treatment prior to initiation of study drugs (either by stereotactic radiosurgery or resection), (2) the patient is not symptomatic from the lesion(s) once local therapy has been administered, and (3) at least one additional, non-treated lesion between 5 mm and 3 cm is still present.
- Prior treatment for either the Melanoma or RCC cohorts may include: Patients must have received at least 2 doses of an anti-PD-1/PD-L1 drug at some point in their treatment course. Any number of prior treatments including PD-1/PD-L1 inhibitors are allowed. Anti-PD-1/PD-L1 does not have to be the most recent therapy. Patients with melanoma who developed brain metastasis within 6 months of the last dose of adjuvant anti-PD-1 can be enrolled.
- Life expectancy of at least 3 months.
- A history of radiotherapy for brain metastases is allowed up to 1 week before study treatment provided that neurologic sequelae are resolved, and that measurable untreated target lesion(s) remain.
- Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. Evaluation of ECOG is to be performed within 7 days prior to the date of allocation.
- Adequately controlled blood pressure (BP) with or without antihypertensive medications, defined as a systolic BP ≤150 or a diastolic BP ≤90 mmHg at screening and on Cycle 1 Day 1.
Note: Eligibility of a participant that is receiving ≥3 antihypertensive medications prior to study entry will require PI approval.
- Have adequate organ function as defined in the protocol. Specimens must be collected within 10 days prior to the start of study treatment.
- Symptomatic melanoma or RCC brain metastases at the time of therapy initiation.
- Active use of corticosteroids to control CNS symptoms, unless steroid requirement has been decreasing and currently on ≤10 mg of prednisone or its equivalent without CNS symptoms for 7 days or more.
- Overt hemorrhage from CNS metastases.
- Presence of leptomeningeal disease.
- Unable to undergo MRI imaging (either due to such conditions as inability to lie flat for the scan duration, incompatible medical devices at risk for malfunction, and foreign metal objects that pose a safety risk for imaging).
- A WOCBP who has a positive urine pregnancy test within 72 hours prior to allocation. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
- Has received anti-cancer therapy including investigational agents within 14 days prior to allocation or less than 4 weeks from prior immunomodulating antibody (excluding anti-PD1/PD-L1).
Note: Participants must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline. Participants with ≤Grade 2 neuropathy, rash, and/or alopecia may be eligible.
Note: If participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment.
- Has received prior CNS radiotherapy within 1 week of start of study treatment. Participants must have recovered from all radiation-related toxicities and not require corticosteroids.
- Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed.
- Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study treatment.
Note: Participants who have entered the follow-up phase of an investigational study may participate as long as it has been 4 weeks after the last dose of the previous investigational agent.
- Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in doses exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.
- Has a known additional malignancy that is progressing or is requiring active treatment.
- Has active autoimmune disease that has required systemic treatment in the past 3 months or a documented history of clinical severe autoimmune disease, or a syndrome that requires chronic systemic steroids or immunosuppressive agents. Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency with prednisone < 10 mg or the equivalent, etc.) is not considered a form of systemic treatment. Subjects with thyroid disease or vitiligo will not be excluded from the study.
