The US Food and Drug Administration (FDA) has granted fast track designation to two hematology drugs: the monoclonal antibody MOR208 to treat relapsed or refractory diffuse large B-cell lymphoma (DLBCL) and the antifibrotic agent PRM-151 to treat myelofibrosis (MF).
The FDA’s fast track program aims to expedite the development and review of drugs that have the potential to fill an unmet medical need in serious or life-threatening conditions.
MOR208
MOR208 is a humanized monoclonal antibody targeting CD19. It is under development by MorphoSys AG to treat B-cell malignancies. The program is in phase 2 clinical development in chronic lymphocytic leukemia (CLL), acute lymphoblastic leukemia (ALL), and non-Hodgkin lymphoma.
Preclinical research with MOR208 revealed that it can trigger natural killer cell-mediated lysis of ALL cells. The drug had lytic activity against ALL cells from both adult and pediatric patients.
In a phase 1 study, MOR208 exhibited preliminary efficacy in patients with high-risk, heavily pretreated CLL, prompting responses in 67% of patients. Researchers said toxicity was acceptable, but infusion reactions were common.
“First results of our ongoing phase 2 trial, which we will present at this year’s ASH conference in December, have helped to identify diffuse large B-cell lymphoma as a valuable development opportunity for MOR208,” said Arndt Schottelius, chief development officer of MorphoSys AG.
“We are therefore delighted to have received the fast track designation for further development of MOR208 in DLBCL. The more frequent interactions with the FDA that this enables will help us to expedite the development of MOR208 in this particular subset of non-Hodgkin’s lymphoma patients.”
PRM-151
PRM-151 is a recombinant form of an endogenous human protein, pentraxin-2, that is specifically active at the site of tissue damage. PRM-151 is an agonist that acts as a monocyte/macrophage differentiation factor to prevent and potentially reverse fibrosis.
The drug has shown broad anti-fibrotic activity in preclinical models of fibrotic disease, including pulmonary fibrosis, acute and chronic nephropathy, liver fibrosis, and age-related macular degeneration.
PRM-151 has orphan designation in the US for MF and in both the US and European Union for the treatment of idiopathic pulmonary fibrosis.
The FDA’s fast track designation for PRM-151 covers primary MF, post-polycythemia vera MF, and post-essential thrombocythemia MF.
“This designation validates our perspective that there is a clear and compelling need for a novel mechanism for the treatment of myelofibrosis that specifically targets the underlying fibrotic processes of the disease,” said Beth Tréhu, MD, FACP, chief medical officer of Promedior Inc., the company developing PRM-151.
“We will continue to work expeditiously to advance this program through the clinic and look forward to presenting the full data set from the first stage of our phase 2 study later this year.”
Preliminary data from the phase 2 study of PRM-151 demonstrated benefits across all clinically relevant measures of MF, including decreases in bone marrow fibrosis, symptom responses, improvements in hemoglobin and platelets, and reductions in spleen size.
The drug also appeared to be well-tolerated and did not prompt myelosuppression.
