Aldeyra Therapeutics Announces Positive Mesothelioma Investigator-Sponsored Clinical Trial Results Presented at The International Association for The Study of Lung Cancer 19th World Conference on Lung Cancer
LEXINGTON, Mass., Sept. 25, 2018
LEXINGTON, Mass., Sept. 25, 2018 /PRNewswire/ -- Aldeyra Therapeutics, Inc. (Aldeyra) (NASDAQ: ALDX), a biotechnology company devoted to development of next-generation medicines to improve the lives of patients with immune-mediated diseases, today announced positive top-line results from the MESO-2 investigator-sponsored Phase 1/2 clinical trial of ADX-1612 (ganetespib) in patients with pleural malignant mesothelioma. ADX-1612, when combined with standard pemetrexed and platinum therapy, resulted in partial response rates that exceeded historical standard of care. ADX-1612 is a selective inhibitor of heat shock protein 90 (Hsp90), a molecular chaperone that controls the folding and activation of client proteins involved in DNA repair and cell division. Results will be announced at a presentation at the International Association for the Study of Lung Cancer (ASLC) 19th World Conference on Lung Cancer (Abstract #11921) on September 25, 2018.
"The MESO-2 results are highly encouraging. Addition of ADX-1612 to pemetrexed and either cisplatin or carboplatin achieved an overall response rate of 61%, the highest seen to date for addition of a novel agent to front-line chemotherapy" said Professor Dean Fennell MD PhD, Chief Investigator of the Cancer Research UK MESO-2 clinical trial. "Hsp90 inhibition could represent a new advance for the treatment of mesothelioma."
The MESO-2 investigator-sponsored dose escalation clinical trial was designed to assess the safety, tolerability, and efficacy of ADX-1612 in combination with standard pemetrexed and platinum therapy, using either cisplatin or carboplatin. Twenty-seven patients with pleural malignant mesothelioma were enrolled at a single site in the UK and divided into one of three cohorts receiving 100, 150, or 200mg/m2 of ADX-1612 on days 1 and 15 every 21 days. Of 23 evaluable patients, 22 patients (96%) manifested stable disease or clinical response, and one patient (4%) with non-epithelial histology progressed, as measured by via RECIST (Response Evaluation Criteria in Solid Tumors) criteria. The overall response rate was 61%, relative to historical standard of care response rates of 20 to 40%. The response rate in patients with epithelial histology was 76%. In seven patients, reduction of tumor burden was greater than 50%. One patient remained progression-free after 37 months. ADX-1612 was observed to be well-tolerated, and dose-limiting toxicity was observed in three patients, all of whom were enrolled in the highest dose group.
"Malignant mesothelioma has no known cure, a poor prognosis, and a treatment landscape that has not changed in over a decade," stated Todd C. Brady, M.D., Ph.D., President and CEO of Aldeyra. "Based on the strength of the MESO-2 investigator-sponsored trial results relative to the unmet medical need in mesothelioma, we look forward to meeting with regulatory authorities to discuss these results."
ADX-1612 (ganetespib) is a selective inhibitor of heat shock protein 90 (Hsp90), a molecular chaperone that controls the folding and activation of client proteins involved in DNA repair and cell division. Aldeyra is developing ADX-1612 for the treatment of lymphoproliferative immune diseases and cancers in combination with DNA-damaging agents.
Malignant pleural mesothelioma is a rare, aggressive cancer that develops in the pleura, a thin layer of tissue surrounding the lungs. Approximately 3,000 people are diagnosed each year in the United States. Response rates to chemotherapy are generally less than 40%, and five-year survival rates are less than 20%.
