Ideal for: Efficacy studies with PDX tumor heterogeneity, mechanisms of chemotherapy (platinum) resistance, clinical trial design and co-clinical trials, cancer initiating cell studies (CIC)
Epithelial ovarian cancer is the most lethal gynecologic malignancy. Recurrence and resistance to standard platinum-based chemotherapy results in poor survival. This published collection of 31 Ovarian and 21 Endometrial PDX models, include different ethnic backgrounds, RNA-seq and mouse data, display varying sensitivities to platinum-based therapies has been utilized in the discovery of key characteristics and potential interventions. The large majority of the tumors tested also correlate with the patient’s platinum response therapies, presenting an opportune collection for both efficacy studies in discovery and clinical trial design (1-3).

PDX collection products & services

  • Xenograft efficacy studies, including collection of blood, tissues and tumor for ADME, PK/PD and analysis.
  • Co-clinical trials for trial design and patient selection
  • OncoRats off-the-shelf for engraftment at the customers facility

In one example, the ovarian PDX model collection has been used to identify Wnt/β-catenin as a novel driver of platinum resistance by maintaining stem-like properties. Targeted inhibition of this pathway overcame platinum resistance by eliminating CICs.

Enabling Case Study: PDX tumor kinetics and response to platinum

PDX tumor, Hera-OV07, generated from a patient who was deemed platinum-resistant, was inherently resistant to platinum-based therapies compared to Hera-OV03, which was isolated from a patient who was platinum-sensitive.
