Time frame: 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]

Time frame: 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

Time frame: 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

Time frame: 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))

Time frame: Up to approximately 42 days after initial dose of tisotumab vedotin

Summarized by descriptive statistics by trial part and dose

Time frame: Throughout and at the end of trial (up to 90 days after last dose of tisotumab vedotin)

Secondary Outcomes

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)

Time frame: 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.

Time frame: 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.

Time frame: Up to approximately 6 months after the first dose of tisotumab vedotin

Tisotumab vedotin in Japanese patients with recurrent/metastatic cervical cancer: Results from the innovaTV 206 study

AbstractNew treatments, particularly second‐line options, are needed to improve outcomes for patients with recurrent/metastatic cervical cancer (r/mCC). Tisotumab vedotin (TV) is an antibody–drug conjugate directed to tissue factor, a transmembrane protein commonly expressed in cancer cells, to deliver cytotoxic monomethyl auristatin E. This single‐arm, open‐label phase 1/2 trial evaluated the consistency of safety and efficacy outcomes of TV in Japanese patients with r/mCC to bridge the current findings with those reported in previous trials in non‐Japanese patients in the United States and Europe. In part 1 (dose escalation; N = 6), patients with advanced solid tumors received TV 1.5 or 2.0 mg/kg once every 3 weeks to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). Part 2 (dose expansion; N = 17) evaluated the RP2D in r/mCC patients with 1–2 prior lines of therapy. In part 1, no dose‐limiting toxicities were observed, the MTD was not reached, and TV 2.0 mg/kg was established as the RP2D. In part 2, the most common treatment‐emergent adverse events were anemia (58.8%), nausea (58.8%), alopecia (47.1%), epistaxis (47.1%), and diarrhea (35.3%); adverse events of special interest were bleeding (76.5%), ocular events (35.3%), and peripheral neuropathy (17.6%), and were mostly grade 1/2. In part 2, confirmed objective response rate was 29.4%, median duration of response was 7.1 months, and median time to response was 1.2 months. In Japanese patients with r/mCC, TV demonstrated a manageable and tolerable safety, pharmacokinetics, and efficacy profile consistent with that observed in non‐Japanese patients.
