Patient case: 46-year-old female with papillary thyroid carcinoma; genetic feature: NTRK1

Clinical trial: Lenvatinib and Weekly Paclitaxel for Patients With Recurrent Endometrial or Ovarian Cancer

Summary: This phase I trial studies the side effects and best dose of lenvatinib mesylate when given together with paclitaxel in treating patients with endometrial, ovarian, fallopian tube, or primary peritoneal cancer that has come back or grown. Lenvatinib mesylate may stop the growth of tumor cells by blocking a protein needed for cell growth and may block the growth of new blood vessels necessary for tumor growth. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving lenvatinib mesylate and paclitaxel together may work better in treating patients with endometrial, ovarian, fallopian tube, or primary peritoneal cancer.

Detailed description: PRIMARY OBJECTIVES:
  I. To determine the recommended phase II dose (RPTD) of combination lenvatinib mesylate (lenvatinib) and weekly paclitaxel in patients with recurrent endometrial, epithelial ovarian, primary peritoneal, or fallopian tube carcinoma.
  SECONDARY OBJECTIVES:
  I. To determine the safety and tolerability of combination lenvatinib and weekly paclitaxel in patients with recurrent endometrial, epithelial ovarian, primary peritoneal, or fallopian tube carcinoma.
  II. To explore the objective antitumor activity (complete and partial response) of combination lenvatinib and weekly paclitaxel as measured by Response Evaluation Criteria in Solid Tumors (RECIST) criteria.
  III. To measure the progression free survival. IV. To evaluate the pharmacokinetics of combination paclitaxel and lenvatinib.
  OUTLINE: This is a dose -escalation study of lenvatinib mesylate.
  Patients receive paclitaxel intravenously (IV) over 1 hour on days 1, 8, and 15 and lenvatinib mesylate orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
  After completion of study treatment, patients are followed up every 3 months for 2 years and then every 3 months for 3 years.

Eligibility: Inclusion Criteria:
  -  Women with histologically confirmed endometrial cancer, epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer (all histological subtypes)who have disease progression after treatment with available therapies that are known to confer clinical benefit or who are intolerant to prior treatment
  -  Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as ≥ 20 mm with conventional techniques or as ≥10 mm with spiral computerized tomography (CT) scan, magnetic resonance imaging (MRI), or calipers by clinical exam
  -  Patients must have received prior treatment with a platinum containing regimen and may have received an unlimited number of prior regimens (including prior taxanes)
  -  Patients with ovarian, Fallopian tube or primary peritoneal cancer must be platinum resistant (progression < 6 months after completion of a platinum containing regimen)
  -  Patients may have received prior targeted therapy such as bevacizumab
