After issuing an ultimatum earlier this year regarding its development efforts for allogeneic CAR-NK cell therapy NKX019 in non-Hodgkin lymphoma (NHL), Nkarta said Thursday that the candidate has officially not passed muster. The drugmaker disclosed in its third-quarter earnings report that, after reviewing Phase I data from a compressed dosing cohort, it will end development of NKX019 in NHL and prioritise its work in autoimmune diseases. Nkarta first revealed its intentions to shift its pipeline priorities away from oncology and into autoimmunity in March, joining a wave of other cell therapy developers encouraged by early data hinting at the potential for CD19-directed CAR-Ts to treat lupus. At the time, the company detailed plans to launch a Phase I trial of NKX019 in lupus — which has since dosed the first patient — and said that development of the cell therapy in NHL was "contingent on favourable outcomes" from the compressed dosing cohort. NKX019 seems to have fallen short of the mark in NHL, but that hasn't dampened Nkarta's autoimmune aspirations. "Safety and accessibility are paramount in autoimmune disease, and we believe that an off-the-shelf, engineered NK cell therapy has the greatest potential to help patients," said CEO Paul Hastings, adding that the company believes "NKX019 has potential to transform patient care" in the disease space.While the candidate didn't get a mention in Nkarta's earnings release, NKX101 appears to be the company's only remaining clinical cancer asset, according to its online pipeline and ClinicalTrials.gov. The NKG2D-directed cell therapy is in a Phase I study for relapsed or refractory acute myeloid leukaemia and myelodysplastic syndrome. Enrollment is closed, and follow-up is ongoing.
