The primary era of cell therapies demonstrated how a affected person’s personal immune cells might be engineered into tumor-hunting most cancers killers. Caribou Biosciences is among the many biotech corporations creating next-generation cell therapies that might provide manufacturing and therapeutic benefits over their predecessors.
Caribou’s story, and maybe its pedigree (Jennifer Doudna, a Nobel prize winner for her CRISPR analysis, is a co-founder) captured sturdy investor curiosity that enabled the clinical-stage biotech to upsize its IPO. The Berkeley, California-based firm initially deliberate to supply 17 million shares within the vary of $14 and $16 every. Late Thursday, it boosted the deal’s dimension to 19 million shares provided on the prime of the projected value vary, elevating $304 million. Caribou’s shares started buying and selling on the Nasdaq Friday below the inventory image “CRBU.”
A rising variety of biotech corporations are pursuing allogeneic cell therapies, “off-the-shelf” therapies that may be made upfront from donor cells, then saved till wanted. These therapies may provide velocity benefits, saving on the time required to fabricate a CAR-T remedy, which is produced by engineering a affected person’s personal T cells in a principally handbook course of that may take weeks. However Caribou contends that genome enhancing applied sciences utilized in allogeneic cell remedy analysis have limitations in relation to the a number of exact genomic edits which can be wanted to make sure the persistence of a cell’s therapeutic impact.
Caribou calls its know-how chRDNA (pronounced chardonnay), which is brief for CRISPR hybrid RNA-DNA. The corporate says that in preclinical analysis, this know-how has demonstrated higher specificity and effectivity, enabling a number of exact genomic edits with “considerably decrease” ranges of off-target edits. Caribou’s preliminary focus is creating allogeneic cell therapies that deal with each blood cancers and stable tumors. The corporate is pursuing CD19 and B cell maturation antigen (BCMA), cell floor targets which were validated by earlier cell therapies, in addition to further targets. However in contrast to the earlier era of cell therapies, Caribou says its cells may provide benefits.

Lead Caribou therapeutic candidate CB-010 is a CAR-T remedy that, like first era CAR-T, targets the CD19 protein expressed on blood most cancers cells. Nevertheless, Caribou’s CAR-T is made through the use of the corporate’s know-how to take away the PD-1 protein from the cell’s floor. The corporate stated within the submitting that knocking out this protein improves the persistence of the cell’s antitumor exercise by disrupting a pathway that results in speedy exhaustion of the T cell. CB-010 is at present being evaluated in a Part 1 research that started on the finish of 2020, enrolling sufferers with B cell non-Hodgkin lymphoma. Preliminary knowledge are anticipated subsequent 12 months.
Caribou’s subsequent product candidate, CB-011, is an allogeneic CAR-T cell remedy that targets the protein BCMA. The corporate makes use of its know-how to include an “immune cloaking strategy” that removes one protein and inserts a transgene. Doing so is meant to blunt the rejection of the cell remedy by a affected person’s T cells and pure killer cells, which in flip allows the cell remedy to have extra sturdy exercise in opposition to tumors. This program is in preclinical improvement for a number of myeloma. A submitting in search of FDA permission to start scientific trials is predicted to be prepared subsequent 12 months.
A 3rd program, CB-012, is an allogeneic armored CAR-T cell remedy for acute myeloid leukemia that targets CD371. Caribou stated that this protein is enticing goal for AML as a result of it’s expressed on myeloid most cancers cells however absent on hematopoietic stem cells. Caribou expects to file an investigational new drug utility in 2023.
Since its founding in 2011, Caribou stated it raised $150.1 million earlier than the IPO. Its largest shareholder is President and CEO Rachel Haurwitz, with a 6.3% post-IPO stake, in response to the prospectus. The biggest institutional shareholder is F-Prime Capital, which owns 6.07% of the corporate after the IPO.
In February, Caribou started a partnership with AbbVie that paid the biotech $30 million up entrance. The alliance requires the corporate to make use of its know-how to develop two allogeneic CAR-T therapies. Caribou may earn as much as $150 million in milestone funds for every program, plus as much as $200 million in business milestones for every program. Within the submitting, Caribou stated that it could search further collaborators.
As of June 30, Caribou reported having about $129.6 million in money. That sum, mixed with its IPO haul, can be deployed all through the corporate’s pipeline. Caribou plans to spend $90 million for Part 1 testing of CB-010 by the reporting of preliminary knowledge, in response to the submitting. One other $80 million is put aside for the preclinical analysis supporting investigational new drug purposes and the potential begin of scientific testing of CB-011 and CB-012. The corporate plans to spend about $55 million on analysis and improvement of its platform for making pure killer cells from induced pluripotent stem cells, in addition to discovery-stage analysis that might spawn further packages.
