This stratification ensures a more targeted and robust analysis of the primary and secondary endpoints of the study.
Preliminary results from the Phase II RAMP-201 study showed an overall response rate (ORR) of 44% in patients with KRAS mutations, compared to 17% in those with wild-type. These figures highlight the importance of KRAS mutation as a predictive biomarker for treatment response, thus justifying the use of the xT CDx assay to optimize treatment protocols. According to Dr. John Hayslip, Chief Medical Officer at Verastem, “Collaborating with Tempus to assess KRAS mutation status using the xT assay has been a key element of the RAMP-201 clinical trial.”
What are the benefits for patients with LGSOC due to this collaboration
Patients with recurrent low-grade serous ovarian cancer who have a KRAS mutation directly benefit from this collaboration. The accelerated approval by the FDA of the combined treatment of avutometinib and defactinib is based on promising Phase II results, which demonstrated increased efficacy in patients with KRAS mutation. This new therapeutic option provides a significant alternative to traditional treatments, which are often limited in effectiveness for this specific type of cancer.
The companion diagnostic developed through this partnership allows for greater personalization of treatments, ensuring that patients receive therapies tailored to their specific genetic profiles. Professor Susana Banerjee, a consulting medical oncologist at the Royal Marsden NHS Foundation Trust, stated at the 2024 annual meeting of the International Gynaecologic Cancer Society (IGCS) that the observed response rate is “significant” and that this therapy could become the new standard of care for the treatment of recurrent LGSOC.
