Should l Buy OMER?
Omeros announced the completion of its initial study in nonhuman primates evaluating the efficacy and safety of its OncotoX-AML cancer therapeutic platform. Omeros' OncotoX-AML therapeutic is first targeting acute myeloid leukemia, an aggressive and highly fatal bone marrow and blood cancer. The effectiveness of current AML treatments, such as chemotherapeutics and antibody-drug conjugates, are limited by substantial side effects. Administration of only one course of OncotoX-AML treatment to immunocompetent primates demonstrated the desired pharmacologic response, specifically marked, selective, reversible, and dose-related reduction in myeloid progenitor cells - the cells that can mutate and lead to AML - by up to 99%. OncotoX-AML was well tolerated, without causing broader or lasting hematologic changes while preserving hematopoietic stem cells. There were no observed safety signals or meaningful changes in blood chemistry values often seen with current AML treatments.
