The primary objective of the trial is to evaluate the clinical anti-tumor activity of EMD 525797 administered as 1-hour intravenous infusion every 3 weeks in terms of progression free survival (PFS) time in subjects with asymptomatic or mildly symptomatic metastatic castrate-resistant prostate cancer (mCRPC).

EMD 525797 in Subjects With Asymptomatic or Mildly Symptomatic Metastatic Castrate-resistant Prostate Cancer

A Randomized, Double-blind, Placebo-controlled, Multicenter Phase II Trial Investigating Two Doses of EMD 525797 in Subjects With Asymptomatic or Mildly Symptomatic Metastatic Castrate-resistant Prostate Cancer (mCRPC)

PFS was defined as time from randomization until the first documented sign of objective radiographic disease progression (ORDP) or death from any cause. Death was considered as an event only if it was reported within 12 weeks after last tumor assessment without progression. ORDP was defined as: Bone lesion progression (2 or more new bone lesions compared to baseline) assessed with bone scintigraphy. Assessment was based on Response Evaluation Criteria in Solid Tumors version 1.0 (RECIST v1.0) modified as per Prostate Cancer Working Group 2 (PCWG-2); Soft-tissue lesion progression assessed with CT scans according to RECIST v1.0 modified as per PCWG-2; Presence of skeletal events defined as cord compression/fracture documented via a scheduled or unscheduled radiographic assessment triggered by increased pain or other signs and/or symptoms, based on the investigator's discretion; Non-radiological events, including emergency bone irradiation and surgery, were not investigated.

Overall Survival was defined as the time from the date of randomization to the date of death from any cause.

Time to tumor progression was defined as the time from the date of randomization to the date of ORDP. ORDP was defined as: Bone lesion progression (2 or more new bone lesions compared to baseline) assessed with bone scintigraphy, which had to be confirmed by bone scintigraphy 6 weeks later if subjects remained asymptomatic or mildly symptomatic. Assessments were to be based on RECIST v1.0 modified according to PCWG-2; Soft-tissue lesion progression assessed with CT scans according to RECIST v1.0 modified as per PCWG-2; Presence of skeletal events defined as cord compression or fracture documented via a scheduled or unscheduled radiographic assessment triggered by increased pain or other signs and/or symptoms, based on the investigator's discretion; Non-radiological events, including emergency bone irradiation and surgery, were not investigated.

Presence of tumor response in soft tissue lesions was defined as the presence of at least 1 confirmed complete response (CR) or confirmed partial response (PR) in soft tissue lesions, documented by computed tomography (CT) scans. Presence of DC in soft tissue lesions was defined as the presence of at least 1 confirmed CR or confirmed PR or stable disease (SD) lasting at least 12 weeks after randomization. Tumor response assessments were based on RECIST v1.0 modified according to the PCWG-2. The response was evaluated for subjects with measurable disease at baseline. According to RECIST v1.0, CR=disappearance of all target and non-target lesions; PR=at least 30% decrease in the sum of the longest diameter of target lesions and non-complete response/non-progressive disease in non-target lesions.

New bone lesions were evaluated by bone scintigraphy for subjects with bone lesions at baseline.

Presence of DC in bone lesions was defined as the appearance of less than 2 new bone lesions, documented by bone scintigraphy.

Bone and soft tissue lesions composite tumor response was defined as the presence of both a confirmed CR or PR, documented by CT scans, and a DC in bone lesions, documented by bone scintigraphy. CR was defined as disappearance of all target and non-target lesions and PR was defined as at least 30% decrease in the sum of the longest diameter of target lesions and non-complete response/non-progressive disease in non-target lesions. Presence of DC in bone lesions was defined as the appearance of less than 2 new bone lesions.

Presence of skeletal related events was defined as cord compression or fracture documented via a scheduled or unscheduled radiographic assessment triggered by increased pain or other signs and/or symptoms at the investigator discretion. Non-radiological events, including emergency bone irradiation and surgery, were not investigated.

PSA response was defined as a decrease greater than 50 percent (%) in PSA value from baseline for 2 consecutive evaluations greater than or equal to (\>=) 3 Weeks apart.

An AE was defined as any new untoward medical occurrences/worsening of pre-existing medical condition without regard to possibility of causal relationship. A serious adverse event was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect. TEAEs were defined as those AEs that started between first dose of study drug and up to 50 days after last dose.

The apparent total body clearance of drug following intravenous administration (CL); The apparent total body clearance of drug at steady state following intravenous administration (CLss).

The apparent volume of distribution during the terminal phase following intravenous administration (V). The estimate of the apparent volume of distribution at steady state following intravenous administration (Vss).

An Open-label, Randomized, Controlled, Multicenter, Phase I/II Trial Investigating 2 EMD 525797 Doses in Combination With Cetuximab and Irinotecan Versus Cetuximab and Irinotecan Alone, as Second-line Treatment for Subjects With K-ras Wild Type Metastatic Colorectal Cancer (mCRC)

DLT was defined as any Grade 4 hematologic toxicity or Grade 3/4 non-hematologic toxicity assessed as related to trial treatment by the Investigator and/or Sponsor and confirmed by the safety monitoring committee (SMC) to be relevant to the combination treatment within the first cycle of therapy. Any Grade 3 or 4 non haematological toxicity, any Grade 4 hematological toxicity, treatment related deaths within the first 2 weeks of therapy. Toxicities excluded from DLT: alopecia, rash, nausea, vomiting and hypomagnesemia of Grade 3 or 4 severity, Grade 4 neutropenia or leukopenia lasting for =\< 5 days and not associated with fever; Single laboratory values out of normal range without any clinical correlation and resolve within 7 days; Grade 3 or 4 diarrhoea without adequate supportive care. Adequate supportive care has been administered and Grade 4 diarrhea persists (investigator decision); isolated Grade 4 lymphocytopenia and thrombocytopenia without clinical correlation.

PFS was defined as the time from the randomization date to first documented sign of objective radio-graphic disease progression (PD) as per Response Evaluation Criteria In Solid Tumors version 1. (RECIST 1.0) or death from any cause if reported within 12 weeks from the last tumor assessment. PD per RECIST v 1.0 was defined as at least 20% increase in the sum of the longest diameter of target lesions, taking as the reference the smallest sum of longest diameters recorded since treatment started, or unequivocal progression of existing non-target lesion or appearance of new lesions. Subjects who did not progress or died at the time of analyses, or subjects who died without previously radio-graphically documented PD and death was observed after more than 12 weeks of last tumor assessment without progression, these subjects were censored at their last tumor assessment date or date of randomization, whichever occurred last.

OS was defined as the time from the date of randomization to the date of death from any cause. For subjects who were still alive at the analysis cut off date or lost to follow up, survival was censored at the last recorded date the subject was known to be alive or at the analysis cut off date, whichever occurred first.

TTP was defined as the time from the date of randomization to the date of objective radiographic disease progression (PD). PD per RECIST v 1.0 was defined as at least 20% increase in the sum of the longest diameter of target lesions, taking as the reference the smallest sum of longest diameters recorded since treatment started, or unequivocal progression of existing non-target lesion or appearance of new lesions. For subjects who did not progress or who were without any post baseline tumor assessment, TTP was censored at their last tumor assessment date, or at the randomization date, whichever occurred last.

Tumor response was defined as the presence of at least 1 confirmed complete response (CR) or confirmed partial response (PR) as judged by RECIST version 1.0. CR was defined for target lesions (TLs) as the disappearance of all lesions, and for non-target lesions (NTLs) as the disappearance of all non-target non-measurable lesions and/or normalization of serum levels of tumor markers. PR was defined for TLs as at least a 30 percent (%) decrease from baseline (BL) in the sum of longest diameter (SLD) of TLs.

TTF was defined as the time from randomization to treatment discontinuation for any reason. For subjects on drug at the analysis cut off date or lost to follow up, TTF was censored at the trial discontinuation date or at the analysis cut off date, whichever occurred first.

Wolfgang Uhl, Dr, Dipl. Chem., Physician

This study is intended to test an experimental new drug called, EMD 525797 (Study Drug). This drug is not yet approved for sale and has only been tested in a small number of people to date (prior to this study starting another research study was carried out involving 37 healthy volunteers receiving the Study Drug). Until more is known about this Study Drug, it can only be used in research studies.

This research study is planned to answer important questions about how the Study Drug is tolerated and how it may work in patients with prostate cancer with bone metastases.

This is a small study which is expected to include 24 patients, and will be conducted in approximately 3 hospitals in Germany and 1 hospital in Brussels, Belgium. The study will last until the last patient has had their last study visit which is expected to be about 18 months in total.

A Study to Determine the Safety, Tolerability, Pharmacokinetics and Dynamic Effects of Different Doses of the Study Drug EMD 525797 in Prostate Cancer

Phase I, Open-label Study to Investigate Safety, Tolerability, PK, and PD of EMD 525797 After Single and Repeated Dosing at Different Dose Levels in Subjects With Hormone-resistant Prostate Cancer With Bone Mets and Progressive Disease Following Prior CTX

DLT was defined using National Cancer Institute Common Toxicity Criteria for Adverse Events Version 3.0 as any Grade 3 or 4 hematological or non-hematological toxicity occurring at any dose level until the end of Week 6, and suspected to be reasonably related to the investigational product by the Investigator and/or Sponsor except for allergic/ hypersensitivity reactions and any Grade 3/4 out-of-range laboratory values without any clinical correlate, which were reversible within 7 days.

An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. Treatment-emergent are events between first dose of study drug that were absent before treatment or that worsened relative to pre-treatment state. TEAEs include both Serious TEAEs and non-serious TEAEs.Treatment-related are events which had causal relationship to study drug as assessed by the Investigator and were suspected to be reasonably related to the study drug.

Area under the serum concentration-time curve from time zero to the last sampling time at which the concentration is at or above lower limit of quantification (LLQ). AUC0-t was calculated according to the mixed log linear trapezoidal rule.

Clearance of a drug was a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Total body clearance of drug from serum, calculated as CL = dose/AUC0-inf. Where AUC0-inf is area under the serum concentration time curve from time zero to infinity, calculated as AUC0 t + AUCextra. AUCextra represents an extrapolated value obtained by Clast/λz, where Clast is the calculated serum concentration at the last sampling time point at which the measured serum concentration is at or above lower limit of quantification (LLQ) and λz is elimination rate constant.

Volume of distribution was defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired serum concentration of a drug. Apparent volume of distribution during the terminal phase, calculated as = Dose/(AUC0-inf \*λz) after first infusion. Where 'λz' is the terminal phase rate constant calculated by a linear regression of the log-linear concentration-time curve. Where AUC0-inf is area under the serum concentration time curve from time zero to infinity, calculated as AUC0 t + AUCextra. AUCextra represents an extrapolated value obtained by Clast/λz, where Clast is the calculated serum concentration at the last sampling time point at which the measured serum concentration is at or above lower limit of quantification (LLQ) and λz is elimination rate constant.

Ctrough is the concentration prior to study drug administration.

Terminal half-life is the time measured for the concentration to decrease by one half. Terminal half-life is calculated by dividing the natural logarithm to the base e (Log e) multiplied by (\*) 2/ λz, where 'λz' is the terminal phase rate constant calculated by a linear regression of the log-linear concentration-time curve.

Elimination rate constant obtained from linear regression of the terminal phase of the log transformed concentration-time data.

Observed minimum serum concentration determined directly from the serum concentration-time profile of each subject.

The average serum concentration at steady state, calculated as Cav = AUCtau/tau, where tau is the dosing interval (336 hours).

Area under the concentration-time curve from time zero up to time Tau, where Tau is the dosing interval (168 hours).

Area under the concentration-time curve from time zero up to time Tau, where Tau is the dosing interval (336 hours).

Area under the serum concentration time curve from time zero to infinity, calculated as AUC0 t + AUCextra. AUCextra represents an extrapolated value obtained by Clast/λz, where Clast is the calculated serum concentration at the last sampling time point at which the measured serum concentration is at or above LLQ and λz is elimination rate constant.

The peak trough fluctuation over one dosing interval at steady state, calculated as PTF (%) = ( \[ Cmax - Cmin \] / Cav )\*100

Mean residence time of drug in the body calculated as: AUMC0-inf / AUC0-inf, where AUMC0-inf is the area under the first moment curve from time zero to infinity. Where AUC0-inf is area under the serum concentration time curve from time zero to infinity, calculated as AUC0 t + AUCextra. AUCextra represents an extrapolated value obtained by Clast/λz, where Clast is the calculated serum concentration at the last sampling time point at which the measured serum concentration is at or above lower limit of quantification (LLQ) and λz is elimination rate constant.

Apparent volume of distribution at steady-state was reported. Apparent volume of distribution was defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired serum concentration of a drug.

Accumulation ratio for Cmax was calculated as Cmax, after third dose/Cmax, after first dose.

Accumulation ratio for AUC, calculated as area under the serum concentration-time curve within one complete dosing interval at third dose divided by area under the serum concentration-time curve within one complete dosing interval at first dose.

Number of subjects with BOR in each category (complete response \[CR\], partial response \[PR\], stable disease \[SD\], progressive disease \[PD\]) according to Response Evaluation Criteria in Solid Tumors (RECIST Version 1.0) was reported. CR: defined as disappearance of all target and all non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR: defined as at least a 30% decrease in sum of longest diameter of target lesions, taking as reference the baseline sum of longest diameter. PD:defined as at least a 20% increase in sum of longest diameter of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study) or unequivocal progression of existing non-target lesions. SD: defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of longest diameter while on study.

PFS PCWG1 criteria: time from the day treatment is initiated up to progression (for subject's whose prostate specific antigen \[PSA\] level did not decrease after baseline, progression defined as 50% PSA increase relative to baseline; for subject's whose PSA decreased after baseline, progression defined as 50% PSA increase relative to nadir \[smallest PSA value post-baseline\]. Progression was confirmed if progression criterion was met in next 2 assessments as well.) PFS PCWG2 criteria: time from study entry to disease progression or death. Progression was defined as first appearance of progression according to PSA (for subject's whose PSA decreased after baseline, progression was defined as 25% PSA increase relative to nadir. Progression was confirmed if another assessment measured at least 3 weeks later met the criterion as well; for subject's whose PSA did not decrease after baseline, progression was defined as 25% PSA increase relative to baseline assessed 12 weeks after baseline).

TTP was calculated as the time between the date of imaging for the earliest visit where progressive disease was detected and the first dose date plus 1 day. Participants without event are censored on the date of last tumor assessment.

ECOG performance status measured to assess subject's performance status on a scale of 0 to 4, where 0=Fully active, able to carry on all pre-disease activities without restriction; 1=Restricted in physically strenuous activity, ambulatory and able to carry out light or sedentary work; 2=Ambulatory (\>50% of waking hours), capable of all self-care, unable to carry out any work activities; 3=Capable of only limited self-care, confined to bed/chair \>50% of waking hours; 4=Completely disabled, cannot carry on any self-care, totally confined to bed/chair. ECOG performance status was reported in terms of number of subjects with Baseline value vs. worst post-baseline value (i.e. highest score) combination.

BPI-sf is an 11-item self-report questionnaire that is designed to assess the severity and impact of pain on daily functions. BPI-sf has 4 questions that assess pain intensity (worst, least, average, right now) and 7 questions that assess impact of pain on daily functions (general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life). Each question is answered on a scale ranging from 0 to 10;'0=No pain and 10=Pain as bad as you can imagine'.Total score is reported as average of individual questions ranges from 0 to 10, with lower scores being indicative of less pain or pain interference.Data was not available for "EMD 525797 250 mg" arm for FUP Weeks 15, 19, 23, 27, 31, 35, 39, 43, 47, 51, 55, 59, 63, 67, 71, 75 and "EMD 525797 1000 mg" arm for FUP Weeks 47, 51, 55, 59, 63, 67, 71 and "EMD 525797 1500 mg arm" for FUP Weeks 35, 39, 43, 47, 51, 55, 59, 63, 67, 71, 75 respectively as no subjects were evaluable at the specified FUP visits.
