The thorium-227 dose will be escalated in a step-wise fashion to the MTD, according to a predefined dose escalation scheme. The total antibody dose of 50 mg will be evaluated first; on the basis of emerging clinical data, doses within the range of 20-100 mg may be investigated.

The thorium-227 dose will be escalated in a step-wise fashion to the MTD, according to a predefined dose escalation scheme. In addition, Darolutamide oral dosing at the approved dose of twice daily 600 mg will be initiated 14 days prior to the first BAY2315497 Injection dose on Day 1 of the first cycle. Daily darolutamide dosing will continue throughout the entire BAY2315497 Injection treatment period until withdrawal criteria from study treatment period are met.

The thorium-227 and total antibody doses, as well as the treatment regimen, will be selected for expansion on the basis of the safety, PK and overall benefit risk profile of BAY2315497 Injection, observed in the course of the dose escalation.

BAY 2315497 Injection comprises 3 components: the PSMA-specific monoclonal antibody (mAb), the mAb-chelator conjugate, and the thorium-227 labeled mAb-chelator conjugate. BAY 2315497 Injection will be administered on Day 1 of each treatment cycle.

600 mg (2 X 300 mg tablets), twice daily with food, equivalent to a total daily dose of 1200 mg.

Darolutamide(BAY1841788)

The study medication (BAY 2315497 Injection) is a thorium-227 labeled immuno-conjugate, specific for the prostate-specific membrane antigen (PSMA), which will be evaluated in patients with metastatic castration resistant prostate cancer. In this study, this investigational medication will be administered to patients for the first time. The primary objective of the study is to define the safety and tolerability profile and Maximal Tolerated Dose (MTD) of BAY2315497 Injection alone, or in combination with darolutamide. The secondary objectives are to determine the recommended dose for further clinical development of BAY2315497 Injection alone, or in combination with darolutamide and to investigate how the study drug is distributed and cleared from the body.

Study to Evaluate the Safety, Tolerability,Pharmacokinetics, and Antitumor Activity of a Thorium-227 Labeled Antibody-chelator Conjugate Alone and in Combination With Darolutamide, in Patients With Metastatic Castration Resistant Prostate Cancer

A Phase 1, Open-label, First-in-human, Multi-center, Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Anti-tumor Activity of a Thorium-227 Labeled Antibody-chelator Conjugate, BAY 2315497 Injection Alone, and in Combination With Darolutamide (BAY 1841788), in Patients With Metastatic Castration Resistant Prostate Cancer

Availability of this study's data will later be determined according to Bayer's commitment to the EFPIA/PhRMA "Principles for responsible clinical trial data sharing". This pertains to scope, timepoint and process of data access. As such, Bayer commits to sharing upon request from qualified researchers patient-level clinical trial data, study-level clinical trial data, and protocols from clinical trials in patients for medicines and indications approved in the US and EU as necessary for conducting legitimate research. This applies to data on new medicines and indications that have been approved by the EU and US regulatory agencies on or after January 01, 2014.

Interested researchers can use www.vivli.org to request access to anonymized patient-level data and supporting documents from clinical studies to conduct research. Information on the Bayer criteria for listing studies and other relevant information is provided in the member section of the portal.

The maximum dose at which the incidence of DLTs occurring during Cycle 1 is below 30%.

The dose / regimen recommended for further clinical development will be defined after evaluation of the safety, PK and overall clinical data, collected in cycle 1 and subsequent cycles, in the dose escalation and dose expansion parts of the study.
