MSB0011359C (M7824) in Metastatic or Locally Advanced Solid Tumors

Adverse event (AE): 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. Serious AE: 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. TEAE: AE with onset after start of treatment or with onset date before the treatment start date but worsening after the treatment start date. TEAEs included both serious and non-serious TEAEs.

Treatment-related TEAEs are any untoward medical occurrence in a participant who received study drug with causal relationship with the investigational product as assessed by the investigator. Related TEAEs were events with relationship missing, unknown or yes. Number of participants With treatment-related TEAEs, treatment-related serious TEAEs and treatment-related TEAE leading to death were reported.

AEs were graded according to severity using NCI-CTCAE Version 4.03. Severity of TEAEs were graded as Grade 1: mild (not causing any significant problem, dose adjustment not required), Grade 2: moderate (caused problem that does not interfere significantly with usual activities or the clinical status, dose adjustment needed due to adverse event), Grade 3: Severe (caused problem that interferes significantly with usual activities or the clinical status, study drug stopped due to adverse event), Grade 4: Life-threatening, Grade 5: Death. Number of Participants with TEAEs and Related TEAEs Based on Severity having Grade greater than or equal to (>=) 3 and Grade >=4 were reported.

A DLT was defined as any grade >= 3 Adverse Event (AE) suspected to be related to IMP by the Investigator and / or Sponsor occurring in the DLT evaluation period confirmed by the Safety Monitoring Committee (SMC) to be relevant for the IMP treatment. According to the NCI-CTCAE, v4.03, occurring in the DLT evaluation period and assessed to be related to study treatment by the Investigator and / or Sponsor confirmed by the safety monitoring committee to be relevant for the study treatment.

BOR according to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 and as adjudicated by the Independent Endpoint Review Committee (IRC). BOR is defined as sum of complete response and partial response (CR+PR). For target lesions (TLs), CR was defined as the disappearance of all TLs; PR was defined as at least a 30% decrease in the sum of largest diameter (SLD) of the TLs, taking as a reference the baseline SLD.

DCR is defined as the percentage of participants with a confirmed CR+PR+SD+ Non-CR/non-PD at any time as per RANO criteria. A responder is a participant with a Complete Response (CR) or Partial Response (PR), and a non-responder is a participant with Stable Disease (SD) or Progressive Disease (PD) assessed by the RANO criteria. CR is no T1 gadolinium enhancing disease, no new lesions, or corticosteroids, and stable or decreasing T2-weighted-Fluid-Attenuated Inversion Recovery (T2/FLAIR). PR is ≥50% decrease in T1 gadolinium enhancing disease, no new lesions, stable or decreasing T2/FLAIR or corticosteroids, and stable or increasing clinical status. SD is <50% decrease in T1 gadolinium enhancing disease but < 25% increase, no new lesions, stable or decreasing T2/FLAIR or corticosteroids, and stable or increase in clinical status. PD is ≥25% increase in T1 gadolinium enhancing disease.

Cmax was obtained directly from the concentration versus time curve.

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

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.

Ctrough is the plasma concentration of a drug prior to administration.

CL is defined as the time it takes for the study drug to be completely removed from the body's plasma.

The detection of antibodies to M7824 was performed using a validated immunoassay method with tiered testing of screening, confirmatory and titration. Number of participants with positive ADA of M7824 were reported.

BOR according to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 and as adjudicated by the Investigator. BOR is defined as sum of complete response and partial response (CR+PR). For target lesions (TLs), CR was defined as the disappearance of all TLs; PR was defined as at least a 30% decrease in the sum of largest diameter (SLD) of the TLs, taking as a reference the baseline SLD.

An Adverse Event (AE) was defined as any new untoward medical occurrences/worsening of pre-existing medical condition without regard to possibility of causal relationship. TEAEs were defined as events with onset date or worsening during the on-treatment period. 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. Any TEAE included participants with both serious and non-serious AEs.

Treatment-related TEAEs are any untoward medical occurrence in a participant who received study drug with causal relationship with the investigational product as assessed by the investigator. Related TEAEs were events with relationship missing, unknown or yes. Number of participants with treatment-related TEAEs, treatment-related serious TEAEs and treatment-related TEAE leading to death were reported.

AEs were graded according to severity using NCI-CTCAE Version 4.03. Severity of TEAEs were graded as Grade 1: mild (not causing any significant problem, dose adjustment not required), Grade 2: moderate (caused problem that does not interfere significantly with usual activities or the clinical status, dose adjustment needed due to adverse event), Grade 3: Severe (caused problem that interferes significantly with usual activities or the clinical status, study drug stopped due to adverse event), Grade 4: Life-threatening, Grade 5: Death. Number of Participants with TEAEs and Related TEAEs Based on Severity having Grade >= 3 and Grade >=4 TEAEs were reported.
