Researchers associated with SEngine Precision Medicine, a precision oncology company that matches patients to medicines based on their own tumor samples, have published a new case report showing a patient's remarkable response to an off-label therapy identified by its PARIS Test.
Despite standard-of-care chemotherapy and two surgeries, the patient's low-grade serous ovarian cancer (LGSOC) was progressing and her prognosis was terminal. But by testing a range of therapies in organoids grown from the patient's own tumor sample, SEngine's PARIS Test identified as a top candidate ibrutinib, a BTK inhibitor approved only for certain leukemias and lymphomas and with no prior clinical evidence of efficacy in ovarian cancer.
Ibrutinib monotherapy led to cessation of opioid-based pain management, the patient's exit from hospice care, and 15 months of stable disease.
The PARIS Test, a unique Clinical Laboratory Improvement Amendments (CLIA)-certified drug sensitivity assay, consists of 3D organoids derived from a patient's tumor. Because no two cancers are identical, SEngine screens an array of drugs from a library of 240 small molecule drugs in the organoids, and develops a personalized report that scores therapies to maximize efficacy and minimize toxicity.
The patient has since continued treatment with two additional PARIS Test-prioritized therapies that are approved only for certain lung cancers. In total, her personalized treatment course has led to over two years of stable disease, compared with a median progression-free survival of 7.2 months for patients with recurrent LGSOC.
Said Dr. Carla Grandori, CEO of SEngine. "We first received a sample of her tumor following an unsuccessful surgery to remove a gastrointestinal obstruction, at a time when she was unable to eat and in hospice care. Her remarkable turnaround reaffirms the power of our approach, and further, helped us identify a cohort of ovarian cancer patients likely to respond to similar precision treatments."

Tests can be ordered using your tumor sample, directly from their website.
Holy cow. 80% success against cancer. That’s incredible.
