MSB0011359C (M7824) in Metastatic or Locally Advanced Solid Tumors

Study Overview
=================
Brief Summary
-----------------
The main purpose of this Phase I study is to test MSB0011359C (M7824) at different dose levels to see if it is safe and well tolerated when given once every 2 weeks. Phase I means the study drug has not previously been given to humans or has only been given to a limited number of people, although it has been extensively studied in animals. Based on this information, it is hoped to find out which dose could be best for the treatment of patients. There are two parts of this research study: a dose-escalation part and an expansion part. Dose escalation means that the first people taking part in the study will receive low doses of the study drug, and as more people take part, the additional participants will receive a higher dose. This is done to find the safest dose for the study drug. Expansion means that after the dose-escalation part of the study has looked at the safety and effectiveness of different doses, many more people will be invited to take part in the study and will receive the study drug at the safest dose. Additional purposes of the study are to find out whether the study drug has anti-cancer effects and how the study drug is processed by the body.

Detailed Description
-----------------
This is a Phase I, open-label, dose-escalation trial with consecutive parallel-group expansion in selected solid tumor indications. The current trial is composed of a standard dose escalation 3 + 3 cohort design, for which 3 to 6 subjects will be enrolled at each dose level depending on the occurrence of dose limiting toxicities (DLTs), followed by a consecutive parallel-group expansion in selected solid tumor indications. Cohorts of 3 subjects with metastatic or locally advanced solid tumors, for which no standard effective therapy exists or standard therapy has failed, will receive MSB0011359C (M7824) at escalating dose levels. After determination of the Maximum tolerated dose (MTD), enrollment in several expansion cohorts will be opened to determine the safety, pharmacokinetic (PK) / Pharmacodynamic, and clinical activity of MSB0011359C (M7824). Subjects who have experienced a confirmed complete response (CR) should continue treatment through the end of 12 months, although additional treatment is possible. In the case of progressive disease (PD), subjects should continue treatment through their next tumor assessment. Additional indications will be planned based on emerging data in the field.

Adequate hematological, hepatic and renal function as defined in the protocol Effective contraception for both male and female subjects if the risk of conception exists Other protocol-defined inclusion criteria could apply. Exclusion Criteria: Concurrent treatment with non-permitted drugs and other interventions Anticancer treatment within 28 days before the start of trial treatment, for example cyto reductive therapy, radiotherapy (with the exception of palliative radiotherapy delivered in a normal organ-spearing technique), immune therapy, or cytokine therapy Major surgery within 28 days before the start of trial treatment (prior diagnostic biopsy is permitted) Systemic therapy with immunosuppressive agents within 7 days before the start of trial treatment; or use of any investigational drug within 28 days before the start of trial treatment Previous malignant disease (other than the target malignancy to be investigated in this trial) within the last 3 years. Subjects with history of cervical carcinoma in situ, superficial or non invasive bladder cancer or basal cell or squamous cell cancer in situ previously treated with curative intent are NOT excluded. Subjects with other localized malignancies treated with curative intent need to be discussed with the Medical Monitor. Rapidly progressive disease which, in the opinion of the Investigator, may predispose to inability to tolerate treatment or trial procedures Subjects with active central nervous system (CNS) metastases causing clinical symptoms or metastases that require therapeutic intervention are excluded Receipt of any organ transplantation, including allogeneic stem-cell transplantation, but with the exception of transplants that do not require immunosuppression (eg, corneal transplant, hair transplant) Other protocol-defined exclusion criteria could apply

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dose-escalation Part: Number of Subjects With Treatment Emergent Adverse Events (TEAEs) | An Adverse Event (AE) is defined as any new untoward medical occurrences/worsening of pre-existing medical condition without regard to possibility of causal relationship. Serious Adverse Event (SAE) is 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. AEs (SAEs and non-SAEs) will be considered TEAEs when emerging on treatment period defined as the time from the first trial drug administration up to 10 weeks after the last drug administration date. | Up to 10 weeks after last treatment | 
| Dose-escalation Part: Number of Subjects With Treatment-Related AEs | Treatment related AEs are any untoward medical occurrence in a subject who received study drug with causal relationship with the investigational product as assessed by the investigator. AEs will be assessed according to severity; mild (not causing any significant problem, dose adjustment not required), moderate (caused problem that does not interfere significantly with usual activities or the clinical status, dose adjustment needed due to adverse event) and severe (caused problem that interferes significantly with usual activities or the clinical status, study drug stopped due to adverse event). | Up to 10 weeks after last treatment | 
| Dose-escalation Part: Number of Treatment Emergent Adverse Events (TEAEs) and Related TEAEs by Severity |  | Up to 10 weeks after last treatment | 
| Dose-escalation Part: Duration of Treatment Emergent Adverse Events (TEAEs) and Related TEAEs |  | Up to 10 weeks after last treatment | 
| Dose-escalation Part: Number of Subjects With Dose Limiting Toxicities (DLT) | A DLT is defined as any grade greater than or equal to (>=) 3 AE suspected to be related to investigational medicinal product (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. | Up to Week 3 | 
| Dose-expansion Part: Best Overall Response (BOR) as Assessed by Independent Endpoint Review Committee (IRC) | BOR according to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 and as adjudicated by the Independent Endpoint Review Committee (IRC).The BOR per IRC adjudication will be determined according to RECIST 1.1 and modified immune related response criteria (irRC), respectively. 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. Overall immune-related complete response: Complete disappearance of all lesions (whether measurable or not) and no new lesions. All measurable lymph nodes also must have a reduction in short axis to 10 mm or less. Overall immune-related partial response (irPR): Sum of the longest diameters of target and new measurable lesions decreases >= 30 percent (%). | Date of randomization up to Week 52 | 
| Dose-expansion Part: Disease Control Rate According to Response Assessment in Neuro-Oncology (RANO) as Adjudicated by the IRC for Subjects With Glioblastoma | The primary efficacy endpoint for the dose expansion part of the trial is the confirmed BOR according to RECIST 1.1 as adjudicated by the Independent Endpoint Review Committee (IRC) and will be evaluated by confirmed objective response rate (ORR). For glioblastoma, the primary endpoint will be disease control according to RANO as adjudicated by the IRC. | Up to Week 52 |
