Two California companies – Nkarta Inc. and Poseida Therapeutics Inc. – scored impressive IPOs but with decidedly different post-pricing performance, as Wall Street showed its enthusiasm for the former’s natural killer (NK) cell research by pushing shares (NASDAQ:NKTX) up 166%, to close July 10 at $47.90, an increase of $29.90.

Nearly a week after filing for a $115 million IPO that it had put off for more than a year, and two months after dosing the first patient in its phase I trial in metastatic castration-resistant prostate cancer, Poseida Therapeutics Inc. has closed on a $110 million series D to continue its CAR T-cell therapy programs.
