Dr. Cheryl Ho is a medical oncologist at Vancouver Cancer Centre. She is one of two study chairs for the clinical trial “Study of Molecular Response Adaptive Immuno-Chemotherapy in Patients with NSCLC” (NCT04093167).
This trial explores the impact of pembrolizumab (Keytruda®), a checkpoint immunotherapy that blocks the PD-1 pathway in patients with non-small cell lung cancer (NSCLC). Lung cancer is the most common cancer worldwide, impacting 2.1 million people and causing an estimated 1.7 million deaths, with NSCLC comprising approximately 85–90% of all cases. The United States reported an estimated 228,000 new lung cancer cases and 142,000 deaths in 2019 alone. When most lung cancer patients become symptomatic and are diagnosed, the disease has already advanced to a stage where surgery, chemotherapy, and radiation are only minimally effective.
Dr. Ho and others investigators are seeking to determine if circulating tumor DNA (ctDNA), a biomarker that can be obtained non-invasively through the blood, can help doctors detect treatment responses in patients sooner than conventional imaging can. Oncologists could then use this information to identity patients resistant to immunotherapy more quickly, and thus allow patients to receive alternative therapies in a more timely fashion.
Additional investigators working on this trial include:
- Adrian Sacher, M.D., Princess Margaret Cancer Centre
- Andrea Fung, M.D., Ph.D., Kingston Health Sciences Centre
- Garth Nicholas, M.D., The Ottawa Hospital Research Institute
- Peter Ellis, M.D., Juravinski Cancer Centre at Hamilton Health Sciences
- Valsamo (Elsa) Anagnostou, M.D., Johns Hopkins University (study chair)
