Latest CIRM TRAN1 awards focus on CAR-based cell therapy to treat cancer

Earlier this week the CIRM ICOC Board awarded $14.5 million to fund three translational stage research projects (TRAN1), whose goal is to support early development activities necessary for advancement to a clinical study or broad end use of a potential therapy. Although all three projects have their distinct area of focus, they all utilize CAR-based cell therapy to treat a certain type of cancer. This approach involves obtaining T cells, which are an immune system cell that can destroy foreign or abnormal cells, and modifying them with a chimeric antigen receptor (CAR). This enables the newly created CAR-engineered cells to identify specific tumor signals and destroy the cancer. In the sections below we will take a deeper look at each one of these recently approved projects.

TRAN1-12245

$2,663,144 was awarded to the University of California, San Francisco (UCSF) to develop specialized CAR-T cells that are able to recognize and destroy tumor cells in glioblastoma, an aggressive type of cancer that occurs in the brain and spinal cord. The specialized CAR-T cells have been created such that they are able to detect two specific signals expressed in glioblastoma. Hideho Okada, M.D., Ph.D. and his team at UCSF will test the therapy in mice with human glioblastoma grafts. They will be looking at preclinical safety and if the CAR-T cell therapy is able to produce a desired or intended result.

TRAN1-12250

$5,949,651 was awarded to the University of California, Los Angeles (UCLA) to develop specialized CAR-engineered cells from human blood stem cells to treat multiple myeloma, a type of blood cancer. Lili Yang, Ph.D. and her team have developed a method using human blood stem cells to create invariant natural killer T (iNKT) cells, a special kind of T cell with unique features that can more effectively attack tumor cells using multiple mechanisms and migrate to and infiltrate tumor sites. After being modified with CAR, the newly created CAR-iNKT cells are able to target a specific signal present in multiple myeloma. The team will test the therapy in mice with human multiple myeloma. They will be looking at preclinical safety and if the CAR-iNKT cells are able to produce a desired or intended result.

TRAN1-12258

Another $5,904,462 was awarded to UCLA to develop specialized CAR-T cells to treat melanoma, a form of skin cancer. Cristina Puig-Saus, Ph.D. and her team will use naïve/memory progenitor T cells (TNM), a subset of T cells enriched with stem cells and memory T cells, an immune cell that remains long after an infection has been eliminated. After modification with CAR, the newly created CAR-TNM cells will target a specific signal present in melanoma. The team will test the therapy in mice with human melanoma. They will be looking at preclinical safety and if the CAR-TNM cells are able to produce a desired or intended result.

CIRM Board Approves Two New Discovery Research Projects for COVID-19

This past Friday the governing Board of the California Institute for Regenerative Medicine (CIRM) approved two new discovery research project as part of the $5 million in emergency funding for COVID-19 related projects.  This brings the number of COVID-19 projects CIRM is supporting to 17, including three clinical trials.

$249,974 was awarded to Dr. Karen Christman at UC San Diego to develop a treatment for Acute Respiratory Distress Syndrome (ARDS), a life-threatening lung injury that occurs when fluid leaks into the lungs and is prevalent in COVID-19 patients.  Dr. Christman and her team will develop extracellular matrix (ECM) hydrogels, a kind of structure that provides support to surrounding cells.  The goal is to develop a treatment that can be delivered directly to site of injury, where the ECM would recruit stem cells, treat lung inflammation, and promote lung healing.

$250,000 was awarded to Dr. Lili Yang at UCLA to develop a treatment for COVID-19.  Dr. Yang and her team will use blood stem cells to create invariant natural killer T (iNKT) cells, a powerful kind of immune cell with the potential to clear virus infection and mitigate harmful inflammation.  The goal is to develop these iNKT cells as an off the shelf therapy to treat patients with COVID-19.

These awards are part of CIRM’s Quest Awards Program (DISC2), which promotes promising new technologies that could be translated to enable broad use and improve patient care.

“The harmful lung inflammation caused by COVID-19 can be dangerous and life threatening,” says Maria T. Millan, M.D., the President and CEO of CIRM. “Early stage discovery projects like the ones approved today are vital in developing treatments for patients severely affected by the novel coronavirus.”

Earlier in the week the Board also approved changes to both DISC2 and clinical trial stage projects (CLIN2). These were in recognition of the Agency’s remaining budget and operational timeline and the need to launch the awards as quickly as possible.

For DISC2 awards the changes include:

  • Award limit of $250,000
  • Maximum award duration of 12 months
  • Initiate projects within 30 days of approval
  • All proposals must provide a statement describing how their overall study plan and design has considered the influence of race, ethnicity, sex and gender diversity.
  • All proposals should discuss the limitations, advantages, and/or challenges in developing a product or tools that addresses the unmet medical needs of California’s diverse population, including underserved communities.

Under the CLIN2 awards, to help projects carry out a clinical trial, the changes include:

  • Adjust award limit to the following:
Applicant typePhase 1, Phase 1/2, Feasability Award CapPhase 2 Award CapPhase 3 Award Cap
Non-profit$9M$11.25M$7.5M
For-profit$6M$11.25M$7.5M
  • Adjust the award duration to not exceed 3 years with award completion no later than November 2023
  • Initiate projects within 30 days of approval
  • All proposals must include a written plan in the application for outreach and study participation by underserved and disproportionately affected populations. Priority will be given to projects with the highest quality plans in this regard.

The changes outlined above for CLIN2 awards do not apply to sickle cell disease projects expected to be funded under the CIRM/NHLBI Cure Sickle Cell Disease joint Initiative.
