Brief Summary:
A Phase 2 Study Evaluating the Efficacy and Safety of DKN-01 as a Monotherapy or in Combination with Paclitaxel in Patients With Recurrent Epithelial Endometrial Cancer, Epithelial Ovarian Cancer, or Carcinosarcoma

Condition or disease Intervention/treatment Phase
Endometrial Cancer Uterine Cancer Ovarian Cancer Carcinosarcoma Drug: Paclitaxel Drug: 300mg DKN-01 Drug: 600mg DKN-01 Phase 2

Detailed Description:

This study employs a "basket" design to concurrently investigate DKN-01 as monotherapy and in combination with paclitaxel in patients with recurrent epithelial endometrial cancer (EEC), epithelial ovarian cancer (EOC), or carcinosarcoma (malignant mixed Mullerian tumor [MMMT]. Thus, 6 distinct patient groups are being independently investigated:

  1. 300mg DKN-01 monotherapy in recurrent EEC (Group 1)
  2. 300mg DKN-01+paclitaxel in recurrent EEC (Group 2)
  3. 300mg DKN-01 monotherapy in recurrent EOC (Group 3)
  4. 300mg DKN-01+paclitaxel in recurrent EOC (Group 4)
  5. 600mg DKN-01 monotherapy in recurrent carcinosarcoma (MMMT) (Group 5)
  6. 600mg DKN-01+paclitaxel in recurrent carcinosarcoma (MMMT) (Group 6)
