Caribou Biosciences

Partnership since March 2021


In March 2021, LLS made an equity investment in Caribou Biosciences to support "A Phase 1, Multicenter, Open-Label Study of CB-010, a CRISPR-Edited Allogeneic Anti-CD19 CAR-T Cell Therapy in Patients With Relapsed/Refractory B Cell Non-Hodgkin Lymphoma (ANTLER)."

Caribou is a leading clinical-stage biotechnology company, co-founded by CRISPR pioneer and Nobel Prize winner Jennifer Doudna, Ph.D., using next-generation CRISPR genome-editing technology to develop “off-the-shelf” (allogeneic) CAR therapies for hard-to-treat blood cancers. Off-the-shelf therapies use donor cells instead of reengineering a patient’s own cells. This approach could make treatment less costly and immediately available to patients with rapidly progressing disease.

CRISPR genome editing uses easily designed, modular biological tools to make DNA changes in living cells. CRISPR systems occasionally edit unintended genomic sites, known as off-target editing, which may lead to harmful effects on cellular function. In response to this challenge, Caribou has developed chRDNAs (pronounced “chardonnays”) that direct substantially more precise genome editing to provide substantial advantages in genome editing specificity and efficiency to enhance persistence and drive clinical durability in multiple malignancies.

CB-010, Caribou’s lead allogeneic CAR-T cell program, targets CD19 and is being evaluated in a Phase 1 clinical trial for patients with relapsed/refractory B cell non-Hodgkin lymphoma (NCT04637763). It is the first clinical-stage allogeneic CAR-T cell therapy in which PD-1 was genetically disrupted in the CAR-T genome, leading to more durable anti-tumor activity in pre-clinical studies. CB-011, Caribou’s second allogeneic CAR-T cell therapy, targets BCMA for the treatment of relapsed/refractory multiple myeloma and is immunologically cloaked for enhanced persistence. CB-012, Caribou’s third allogeneic CAR-T cell therapy, targets CD371 for the treatment of relapsed/refractory acute myeloid leukemia.

  • July 27, 2021 - announced  the closing of its previously announced initial public offering of 19,000,000 shares of common stock, at a price to the public of $16.00 per share. The aggregate gross proceeds to Caribou from the offering were approximately $304.0 million.
  • July 12, 2021 – announced  that the first patient has been dosed in its open-label, multicenter ANTLER phase 1 clinical trial (NCT04637763) to evaluate the company’s lead product candidate, CB-010, in patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL). CB-010 is an allogeneic anti-CD19 CAR-T cell therapy derived from healthy donor T cells that have been engineered using Caribou’s chRDNA technology to reduce the risk of graft versus host disease (GvHD) and knock out PD-1 to boost the persistence of CAR-T cell antitumor activity. 
  • March 3, 2021 – announced the successful completion of an oversubscribed $115 million Series C financing. Proceeds from the financing will be used to further develop the Company’s proprietary, next-generation CRISPR technology platform and to advance the Company’s pipeline of wholly-owned allogeneic immune cell therapies for oncology with best-in-class potential.
