Summary

This is a Phase 3, multi-center, randomized, open-label, controlled study designed to evaluate the safety and efficacy of cabozantinib given in combination with atezolizumab versus a second novel hormonal therapy (NHT) in men with metastatic castration-resistant prostate cancer (mCRPC) who have previously been treated with one, and only one, NHT for their prostate cancer disease.

Description

The primary objective of this study is to evaluate the efficacy of cabozantinib (XL184) in combination with atezolizumab versus a second NHT (abiraterone or enzalutamide) in subjects with mCRPC who have previously been treated with one, and only one, NHT (e.g. abiraterone, apalutamide, darolutamide, or enzalutamide) to treat metastatic castration-sensitive prostate cancer (mCSPC), non-metastatic CRPC (M0 CRPC), or mCRPC, and who have measurable extrapelvic disease. The multiple primary efficacy endpoints comparing the experimental arm and control arm are Duration of Progression Free Survival (PFS) per RECIST 1.1 by Blinded Independent Radiology Committee (BIRC) and Duration of Overall Survival (OS). The secondary efficacy endpoint is Objective Response Rate (ORR) per RECIST 1.1 per BIRC.

Eligibility		Yes	No	Not Sure
Inclusion Criteria
	Men with histologically or cytologically confirmed adenocarcinoma of the prostate
	Prior treatment with one, and only one, NHT (eg, abiraterone, apalutamide, darolutamide, or enzalutamide) for castration-sensitive locally advanced (T3 or T4) or mCSPC, M0 CRPC, or mCRPC
	Surgical or medical castration, with serum testosterone 50 ng/dL ( 1.73 nmol/L) at screening
	Measurable (extrapelvic soft tissue) metastatic disease per Investigator assessment defined by at least one of the following: measurable visceral disease (eg, adrenal, kidney, liver, lung, pancreas, spleen) per RECIST 1.1; OR measurable extrapelvic adenopathy (ie, adenopathy above the aortic bifurcation)
	Progressive disease at study entry as defined by specific criteria for prostate specific antigen (PSA) progression OR soft tissue disease progression in the opinion of the Investigator (Note: subjects with bone disease progression alone are not eligible)
	Age 18 years old or meeting country definition of adult, whichever is older, on the day of consent
	ECOG performance status of 0 or 1
	Recovery to baseline or Grade 1 per Common Terminology Criteria for Adverse Events (CTCAE) v5 from toxicities related to any prior treatments, unless AE(s) are clinically nonsignificant and/or stable on supportive therapy in the opinion of the Investigator
	Adequate organ and marrow function based upon specific laboratory assessments obtained within 21 days prior to randomization
	Understanding and ability to comply with protocol requirements
Exclusion Criteria
	Any prior nonhormonal therapy initiated for the treatment of mCRPC
	Receipt of abiraterone within 1 week; cyproterone within 10 days; or flutamide, nilutamide, bicalutamide, enzalutamide, or other androgen-receptor inhibitors within 2 weeks before randomization
	Radiation therapy within 4 weeks (2 weeks for bone metastases) prior to randomization (subjects with clinically relevant ongoing complications from prior radiation therapy are not eligible)
	Known brain metastases or cranial epidural disease unless adequately treated and clinically stable at least 4 weeks prior to randomization
	Symptomatic or impending spinal cord compression or cauda equina syndrome
	Concomitant anticoagulation with oral anticoagulants (some specific exceptions apply)
	Administration of a live, attenuated vaccine within 30 days prior to randomization
	Systematic treatment with, or any condition requiring, either corticosteroids (>10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days prior to randomization
	Uncontrolled, significant intercurrent or recent illness
	Major surgery within 4 weeks prior to randomization
	Corrected QT interval calculated by the Fridericia formula (QTcF) > 480 ms per ECG within 21 days before randomization
	Inability or unwillingness to swallow pills or receive IV administration
	Previously identified allergy or hypersensitivity to components of the study treatment formulations or history of severe infusion-related reactions to monoclonal antibodies
	Any other active malignancy at time of randomization or diagnosis of another malignancy within 2 years prior to randomization that requires active treatment (some exceptions apply such as locally curable cancers that have apparently been cured)
