• Major surgery within 4 weeks prior to initiation of study treatment.
• Received the last dose of anticancer therapy = 28 days prior to the first dose of study drug.
• All toxicities NCI CTCAE Grade =2 attributed to prior anti-cancer therapy other than alopecia, vitiligo, and neuropathy.
• Any concurrent chemotherapy, IP, biologic, or hormonal therapy for cancer treatment.
• History of allogenic organ transplantation.
• Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, checkpoint inhibitor-induced immune mediated reaction or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.]).
• Patient with uncontrolled intercurrent illness including, but not limited to, uncontrolled infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, significant muscle disorders or psychiatric illness/social situations that would limit compliance with study requirements.
• History of known additional primary malignancies.
• History of leptomeningeal carcinomatosis.
• Brain metastases or spinal cord compression.
• History of active primary immunodeficiency.
• Infection with Tuberculosis, HIV or hepatitis B or C at screening.
• Current or prior use of immunosuppressive medication within 14 days before the first dose of treatment.
• Receipt of live attenuated vaccine within 30 days prior to the first dose of IP.
• Pregnant or breastfeeding women.
• Has a history of allergy to study treatments or any of its components of the study.
• Prior randomization or treatment in a previous durvalumab and/or SNDX-6532 clinical study regardless of treatment arm assignment.
• Patient has clinically significant heart disease.
• Any other sound medical, psychiatric, and/or social reason as determined by the Investigator.
• Unwilling or unable to follow the study schedule for any reason.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective Response Rate (ORR) Per mRECIST (Modified RECIST)	ORR is defined as the number of patients achieving a complete response (CR) or partial response (PR) based on the Response Evaluation Criteria in Solid Tumors (mRECIST) at any time during the study. CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions, progressive disease (PD) is >20% increase in sum of diameters of target lesions, stable disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions. Estimation based on the Kaplan-Meier curve.	8 months
Primary	Number of Participants Experiencing Study Drug-related Toxicities	Number of participants who experience treatment related adverse events = grade 3 as defined by CTCAE 5.0.	up to 1 year
Secondary	Overall Survival (OS)	OS will be measured from date of first dose until death or end of followup (OS will be censored on the date the subject was last known to be alive for subjects without documentation of death at the time of analysis). Estimation based on the Kaplan-Meier curve.	4 years
Secondary	Progression-free Survival (PFS) Per mRECIST	PFS is defined as the number of months from the date of treatment to disease recurrence [disease recurrence (DR) progressive disease (PD) or relapse from complete response (CR) as assessed using mRECIST criteria] or death due to any cause. Per mRECIST criteria, CR = disappearance of all target lesions, Partial Response (PR) is =>30% decrease in sum of diameters of target lesions, Progressive Disease (PD) is >20% increase in sum of diameters of target lesions, Stable Disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions.	4 years
Secondary	Duration of Response (DOR)	Number of weeks from the start date of PR or CR (whichever response is recorded first) and subsequently confirmed to the first date that recurrent or progressive disease or death is documented. Per mRECIST, CR = disappearance of any intratumoral arterial enhancement in all target lesions, PR is =>30% decrease in sum of diameters of target lesions.	4 years
