A Trial of Tisotumab Vedotin in Japanese Subjects With Advanced Solid Malignancies

Study Overview
=================
Brief Summary
-----------------
Open Label Phase 1/2 Trial of Tisotumab Vedotin in Japanese Subjects with Advanced Solid Malignancies

Detailed Description
-----------------
Part 1 of this trial will determine the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) and the safety profile of tisotumab vedotin in subjects with solid malignancies. Part 2 of this trial will enroll subjects with cervical cancer to provide further data on the safety, tolerability, PK and anti-tumor activity

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dose Escalation and Dose Expansion: Incidence of drug-related Adverse Events (AEs) and Serious Adverse Events (SAEs) by CTCAE v5.0 [Safety] |  | Throughout the trial - until 90 days after last dose of tisotumab vedotin | 
| Dose Escalation and Dose Expansion: Incidence of Dose Limiting Toxicities (DLTs), AEs, SAEs, adverse events leading to discontinuation, deaths and clinical laboratory test abnormalities [Tolerability] |  | Throughout the trial - until 90 days after last dose of tisotumab vedotin | 
| Dose Escalation: maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) of tisotumab vedotin |  | Up to 21 days after the first dose of tisotumab vedotin (each cycle is 21 days) | 
| Dose Escalation and Dose Expansion Pharmacokinetics of tisotumab vedotin: Maximum concentration (Cmax) after dosing |  | Up to approximately 42 days after initial dose of tisotumab vedotin | 
| Dose Escalation and Dose Expansion Pharmacokinetics of tisotumab vedotin: Area under the plasma concentration-time curve from time 0 to the last measurable concentration (AUC(0-t)) |  | Up to approximately 42 days after initial dose of tisotumab vedotin | 
| Dose Escalation and Dose Expansion Pharmacokinetics of tisotumab vedotin : Rate at which the drug is removed from the body (CL) |  | Up to approximately 42 days after initial dose of tisotumab vedotin | 
| Dose Escalation and Dose Expansion Pharmacokinetics of tisotumab vedotin: Elimination half-life of the drug (T½) |  | Up to approximately 42 days after initial dose of tisotumab vedotin | 
| Dose Escalation and Dose Expansion Pharmacokinetics of tisotumab vedotin: Time after dosing at which the maximum drug concentration was observed (Tmax) |  | Up to approximately 42 days after initial dose of tisotumab vedotin | 
| Dose Escalation and Dose Expansion: Assess immunogenicity of tisotumab vedotin by measuring and assessing Anti-drug Antibody (ADA) | Summarized by descriptive statistics by trial part and dose | Throughout and at the end of trial (up to 90 days after last dose of tisotumab vedotin) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dose Escalation and Dose Expansion: Evaluate antitumor activity of tisotumab vedotin by assessing Objective Response Rate (ORR) (based on RECIST 1.1) | ORR defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) | Up to approximately 6 months after the first dose of tisotumab vedotin | 
| Dose Escalation and Dose Expansion: Evaluate antitumor activity of tisotumab vedotin by assessing Duration of Response (DOR) (based on RECIST 1.1) | The DOR for a responder is defined as the time from the participant's initial objective response to the first date of either disease progression or death, whichever occurs first. | Up to approximately 6 months after the first dose of tisotumab vedotin | 
| Dose Escalation and Dose Expansion: Evaluate antitumor activity of tisotumab vedotin by assessing Time to Response (TTR) (based on RECIST 1.1) | TTR for a responder is defined as the time from the start of treatment with study drug to the first objective tumor response observed. | Up to approximately 6 months after the first dose of tisotumab vedotin |
