ORYZON announces first patient dosed in NCI-sponsored Phase I/II clinical trial of iadademstat plus immune checkpoint inhibitors in 1L extensive stage Small Cell Lung Cancer
Oryzon Genomics has launched a clinical trial in the U.S. to evaluate for the first time the combination of its epigenetic inhibitor iadademstat with immunotherapy in patients with metastatic small cell lung cancer, in collaboration with the National Cancer Institute.
Oryzon Genomics S.A., (ISIN Code: ES0167733015, ORY), a clinical-stage biopharmaceutical company leveraging epigenetics to develop therapies in diseases with strong unmet medical need, announced today that the first patient has been dosed in a Phase I/II trial of iadademstat, Oryzon’s potent and selective LSD1 inhibitor, in combination with immune checkpoint inhibitors (ICI) in first line small cell lung cancer (SCLC) patients with extensive disease, sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health. This is the first clinical trial testing the combination of iadademstat with ICI.
The trial (NCT06287775), titled “A Phase I Dose Finding and Phase II Randomized Trial of Iadademstat Combined With Immune Checkpoint Inhibition Maintenance After Initial Chemoimmunotherapy in Patients With Extensive-Stage Small Cell Lung Cancer”, will evaluate the safety, tolerability, dose finding and efficacy of iadademstat in combination with an ICI, either atezolizumab or durvalumab, in patients with extensive stage SCLC who have initially received standard of care chemotherapy and immunotherapy. This Phase I/II clinical study is conducted and sponsored by the NCI, with Dr. Charles Rudin, from the Memorial Sloan Kettering Cancer Center (MSKCC) as the Principal Investigator. The trial will be conducted at a number of prestigious cancer centers in the US, including the MSKCC, the JHU Sidney Kimmel Comprehensive Cancer Center and many others. The trial plans to enroll 45-50 patients and will be carried out under a Cooperative Research and Development Agreement (CRADA) that Oryzon has in place with the NCI.
Dr. Carlos Buesa, Oryzon’s CEO, stated: “We are very excited to have the first patient dosed in this study. The biology underlying iadademstat’s ability to make SCLC cells visible to the immune system and to boost significantly the number and the activation of cytotoxic CD8+ T cells is fascinating. Moreover, prior analyses of several Phase III trials in SCLC indicate that low LSD1 expression is a key factor in determining patients' likelihood of responding and surviving. If this trial confirms the preliminary findings reported by researchers at MSKCC and others, it would reinforce the rationale for this combination as a therapeutic option for this critically underserved patient population. In the event of positive results, the company could also initiate a complementary trialto generate additional data in support of a potential accelerated registration strategy.”
