What is this Case About: Caribou Biosciences, Inc. (CRBU) Made False and Misleading Statements in Connection with its IPO Regarding the Viability of its Drug Candidate
According to the complaint, the registration statement filed in connection with the IPO was materially false and misleading because it failed to disclose that CB-010’s treatment effect was not as durable as defendants had led investors to believe, and accordingly, CB-010’s clinical and commercial prospects were overstated.
On June 10, 2022, Caribou issued a press release reporting “[p]ositive” data from the ANTLER Phase 1 clinical trial. Among other results, Caribou reported that “[a]t 6 months following the single dose of CB-010, [only] 40% of patients remained in CR [complete response] (2 of 5 patients) as of the May 13, 2022 data cutoff date”, prompting investor concern over the durability of the CB-010 treatment. On this news, Caribou’s stock price fell $1.78 per share, or 20.41%, to close at $6.94 per share on June 10, 2022.
Then, on December 12, 2022, Caribou issued a press release “report[ing] new 12-month clinical data from cohort 1 in the ongoing ANTLER Phase 1 trial, which [purportedly] show[ed] long-term durability following a single infusion of CB-010 at the initial dose level 1 (40x106 CAR-T cells).” Among other results, Caribou reported that “3 of 6 patients maintained a durable CR at 6 months” and “2 of 6 patients maintain a long-term CR at the 12 month scan and remain on the trial”, thereby confirming investor fears that the CB-010 treatment lacked significant durability. On this news, Caribou’s stock price fell $0.81 per share, or 9.03%, to close at $8.16 per share on December 12, 2022.
