Juno Therapeutics, Inc. (NASDAQ:JUNO) along with partner Celgene Corporation (NASDAQ:CELG) announced additional data from a phase I study (TRANSCEND) on its lead pipeline candidate, JCAR017 (lisocabtagene maraleucel), for treatment of patients with relapsed or refractory (r/r) aggressive non-Hodgkin lymphoma (“NHL”). Results were presented at the 59th annual meeting of American Society of Hematology.

Notably, JCAR017 is a next-generation chimeric antigen receptor and high-affinity T cell (CAR-T) receptor product that targets CD19.

The company presented separate data from the TRANSCEND study for the full group of patients enrolled as well as the core group i.e. a high-risk patient population.

Finds from the multi-center TRANSCEND trial demonstrated that at dose level 2, 74% of patients with the aforementioned indication showed an overall response rate (ORR) and 68% complete response (“CR”) rate at three months in core group. Additionally, 50% of patients showed CR at six months.

These figures are better than the previous data of 66% ORR and 50% CR reported in June. Moreover, the safety profile of JCAR017 remains impressive with only 1% of patients experiencing severe cytokine release syndrome and 15% experiencing severe neurotoxicity.

It is interesting to note that Juno’s shares dropped almost 15% following the news release probably as investors expected better response rates. However, shares of Juno have significantly gained 166.5% of its value so far this year, comparing favorably with the industry ’s increase of 3%.
