SUMMERLIN, Nev., Dec. 14, 2021 /PRNewswire/ -- Secura Bio, Inc. (Secura Bio) - (www.securabio.com), an integrated pharmaceutical company dedicated to the worldwide development and commercialization of impactful oncology therapies, today announced that new data for the treatment of relapsed or refractory(r/r) PTCL patients with COPIKTRA were presented at the 63rd annual meeting of the American Society of Hematology (ASH) in Atlanta, Georgia.
Jonathan Brammer M.D. of The Ohio State University James Comprehensive Cancer Center presented the interim analysis of the phase 2 PRIMO trial of r/r PTCL patients treated with single-agent COPIKTRA 75mg BID for the first two months followed by 25mg BID until progression or unacceptable toxicity. 78 of a planned 125 patients were included in this analysis with a minimum follow-up of 6 months. The trial is ongoing, with completion expected in 2022.
The interim results include an ORR by IRC assessment of 50% (39/78 pts) and a CR of 32.1% (25/78) with a median duration of response of 233 days (range, 1-420+). Patients had a median of 3 (range, 1-7) prior therapeutic regimens and included the following PTCL subtypes: PTCL NOS (53.8%), ALCL (14.1%), AITL (26.0%) and Other (0.5%). 18% of patients remain on therapy, 47.4% discontinued due to PD, 6.4% discontinued for stem cell transplant, and 19.2% discontinued due to unacceptable toxicity.
Overall, the safety profile was consistent with previous studies; in this analysis the most frequent > Grade 3 adverse events seen were neutropenia (38.5%), ALT/AST increased (24.4%/ 21.8%), rash (7.7%), lymphocyte count decreased (7.7%), and sepsis (6.4%). ALT and/or AST elevations were the most common AEs leading to treatment discontinuations (N=12, 15.4%).
"Patients with r/r PTCL usually relapse quickly and have limited treatment options, and the data from the PRIMO trial show very promising activity and even a remarkable number of complete responses. Importantly, these responses are better than current standard of care options" said Dr. Brammer.
"We are encouraged to see such robust responses in a significant number of patients who are suffering with these aggressive forms of lymphoma" said David Cohan M.D., Chief Medical Officer at Secura Bio. "We will continue to develop COPIKTRA for the treatment of the r/r population, and we have also expanded our clinical research program to include earlier lines of therapy for various T-cell lymphomas."

About COPIKTRA (duvelisib)
COPIKTRA is an oral inhibitor of phosphoinositide 3-kinase (PI3K), and the first United States FDA approved dual inhibitor of PI3K-delta and PI3K-gamma, two enzymes known to help support the growth and survival of malignant cells. PI3K signaling may lead to the proliferation of malignant cells and is thought to play a role in the formation and maintenance of a supportive tumor microenvironment. COPIKTRA is indicated in the United States for the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) after at least two prior therapies. COPIKTRA is also being developed for the treatment of peripheral T-cell lymphoma (PTCL), for which it has received Fast Track designation in the United States. COPIKTRA is being investigated in combination with other agents across several types of solid and hematologic malignancies, through investigator-sponsored studies.
