FDA Halts Phase I Trial of PPI-2458 in Non-Hodgkin's Lymphoma Patients
In support of its Investigational New Drug application, the Company had completed and submitted to the FDA results from preclinical studies evaluating the safety of PPI-2458 through 28-days of treatment. These studies showed no evidence of any unexpected safety issues. The FDA's decision was related to a preliminary finding in a recently completed three-month animal safety study. The findings of this study were not available at the time that the clinical study was initiated. The finding consisted of a neuropathological abnormality in some of the animals tested, similar to findings reported in connection with other approved products. The Company will further explore this finding, with input from leading experts as appropriate, to assess its potential implications and prepare a plan for the FDA.
"We remain committed to the development of PPI-2458 for non-Hodgkin's lymphoma, as well as additional evaluation of its activity in other cancers, and will work diligently with the FDA to agree upon an acceptable path forward that will optimize the safest possible use of this novel therapeutic agent," said Marc B. Garnick, M.D., Executive Vice President and Chief Medical Officer of PRAECIS.
