Clinical Trial Summary

This is the first study where BAY2010112 is given to humans. Patients with castration resistant prostate cancer will be treated. Every patient will receive drug treatment, there is no placebo group. Patients will receive different dosages of BAY2010112 to determine the safety, tolerability and maximum tolerated dose (MTD) of BAY2010112.

The study will also assess the pharmacokinetics and the clinical efficacy of BAY2010112.

BAY2010112 will be given daily as subcutaneous injection or as continuous intravenous infusion. Treatment will be stopped if the tumor continues to grow, if side effects, which the patient cannot tolerate, occur or if the patient decides to exit treatment.

• Total serum testosterone should be less than 50 ng/ml or 1.7 nmol/L

• Evidence of progressive disease, defined as one or more (Prostate Cancer Working Group 2 (PCWG2) criteria):

• PSA level of at least 2 ng/ml that has risen on at least 2 successive occasions at least 1 week apart

• Nodal (in lymph nodes >/= 2cm) or visceral progression as defined by Response Evaluation Criteria in Solid Tumors (RECIST)

• Confirmed history or current autoimmune disease or other diseases resulting in permanent immunosuppression or requiring permanent immunosuppressive therapy

• Prior radiotherapy (local palliative radiotherapy is permitted)

• History of allergic reactions to monoclonal antibody therapy

• History of clinical significant cardiac disease: including unstable angina, acute myocardial infarction within 6 months prior to first study treatment, congestive heart failure =New York Heart Association (NYHA) Class III), and arrhythmia requiring therapy except for beta-blockers, calcium channel blockers and digoxin or uncontrolled hypertension, despite optimal medical management

• Clinically relevant findings in the electrocardiogram (ECG) such as a second- or third-degree AV block, prolongation of the QRS complex over 120 msec or of the QT interval corrected for heart rate (QTc)-interval over 450 msec

• Current evidence or history of uncured (i.a. any absolute risk of latent infection) of hepatitis B or C or human immunodeficiency virus (HIV) infection

• Chronic systemic corticosteroid therapy or any other immunosuppressive therapies should have been stopped at screening start

• Seizure disorder requiring therapy (such as steroids or anti-epileptics)

• Subjects unable to inject the study drug subcutaneously for intended s.c. application

• Non-suitable for a central venous access for intended c.i.v. administration

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of participants with Adverse Events as a Measure of Safety and Tolerability		Up to 2 years or longer if indicated
Primary	Maximum Tolerated Dose (MTD)	MTD is measured by adverse event profile at the end of Cycle 1. MTD will be the highest dose level achieved during dose escalation where the incidence of dose-limiting toxicities (DLTs) is below 20%	Up to 2 years or longer if indicated
Secondary	Maximum drug concentration (Cmax) of BAY2010112 in serum after single and multiple doses administration		Cycle 1 Day1 and 15; (1 Cycle is 21 days long)
Secondary	Area under the concentration versus time curve (AUC) from zero to infinity after single (first) and multiple doses of BAY2010112		Cycle 1 (1 Cycle is 21 days long)
Secondary	Tumor response	Tumor response is measured by measurable lesions	Up to 2 years or longer if indicated
Secondary	Prostate-specific antigen (PSA) response	PSA response is measured by maximum decline in PSA that occurs at any point after treatment	Up to 2 years or longer if indicated
