A Study of Weekly Tisotumab Vedotin for Patients With Platinum-Resistant Ovarian Cancer With Safety Run-in (innovaTV 208)

Inclusion Criteria:

   - Histologic documentation of epithelial ovarian cancer, primary peritoneal cancer, or
   fallopian tube cancer

   - Safety run-in only: PROC. Patients may have received more than 1 prior systemic
   treatment regimen in the PROC setting.

   - Part A and Part B only: Patients with PROC who have received 1 to 3 anticancer lines
   of therapy overall, including at least 1 line of therapy containing bevacizumab or
   biosimilar.

      - Adjuvant ± neoadjuvant are considered 1 line of therapy.

      - Patients may have received a PARP inhibitor or an immuno-oncology (IO) agent; any
      of these regimens are to be considered a line of therapy for the purposes of this
      study if not used as maintenance therapy.

      - Maintenance therapy (including bevacizumab, PARP inhibitors and IOs) will be
      considered part of the preceding line of therapy and not to be counted as a new
      line of therapy.

      - Any chemotherapy regimen change due to toxicity in the absence of disease
      progression is considered as part of the same line of therapy.

      - Hormonal therapy will be not be counted towards the lines of therapy.

   - Measurable disease according to RECIST v1.1 as assessed by the investigator

   - An Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0 or 1

   - Life expectancy of at least 3 months

   - Able to provide fresh or archival tissue for biomarker analysis

Exclusion Criteria:

   - Primary platinum-refractory disease, defined as disease progression within 2 months of
   completion of first line platinum-based therapy

   - Patients with clinical symptoms or signs of gastrointestinal obstruction with the past
   6 months or who currently require parenteral nutrition

   - Hematological: Known past or current coagulation defects leading to an increased risk
   of bleeding, diffuse alveolar hemorrhage from vasculitis, known bleeding diathesis,
   ongoing major bleeding, or trauma with increased risk of life-threatening bleeding
   within 8 weeks of trial entry

   - Cardiovascular: Clinically significant cardiac disease including uncontrolled
   hypertension, unstable angina, acute myocardial infarction with 6 months of screening,
   serious cardiac arrhythmia requiring medication, medical history of congestive heart
   failure, or medical history of decreased cardiac ejection fraction of <45%

   - Ophthalmological: Active ocular surface disease at baseline or prior episode of
   cicatricial conjunctivitis or Stevens Johnson syndrome

   - Prior treatment with MMAE-derived drugs

   - Inflammatory bowel disease including Crohn's disease and ulcerative colitis

   - Ongoing, acute, or chronic inflammatory skin disease

   - Uncontrolled tumor-related pain

   - Inflammatory lung disease requiring chronic medical therapy

   - Grade 3 or higher pulmonary disease unrelated to underlying malignancy

   - Uncontrolled pleural or pericardial effusions

   - Grade >1 peripheral neuropathy
