# Off-the-shelf engineered NK cells for the treatment of AML > **NIH NIH R01** · UNIVERSITY OF TX MD ANDERSON CAN CTR · 2020 · $162,000 ## Abstract ABSTRACT The coronavirus (COVID-19) pandemic has spread rapidly and globally to infect over 3 million individuals, with no effective therapeutic options for patients with serious and life-threatening complications. The impact of this infection is likely to be especially serious in patients undergoing hematopoietic stem cell transplant (HSCT), in particular umbilical cord blood transplant (CBT) recipients or those receiving chimeric antigen receptor (CAR) T or NK cell therapies, given their immunocompromised state, presence of medical comorbidities, and concerns for higher infection-related severity and mortality. Our team has developed robust clinical banks of HLA-typed GMP-grade viral-specific T lymphocytes (VSTs) targeting cytomegalovirus (CMV), BK virus (BKV) and adenovirus. We have treated over 100 HSCT recipients, 49% of whom had received CB or haploidentical transplants, with these partially HLA-matched and off-the-shelf VSTs on FDA-approved clinical protocols with a >80% response rate and no toxicity. We have successfully applied this platform to establish the protocols for the manufacture of GMP-grade COVID-19 specific T cells. We propose to generate a biobank of COVID-19 specific T cells from donors who have recovered from COVID-19 infections using IRB-approved protocols (MDACC Lab02-0630) in the MDACC GMP Facility. We will then conduct a phase I/II clinical trial to evaluate the safety, feasibility and antiviral activity of third-party, off-the-shelf, most closely HLA-matched COVID-19 specific T cells in HSCT including CBT/haploidentical transplant or cell therapy recipients with severe COVID-19 infections (Aim 1). To expedite the approval of this trial for our patients, we recently amended another VST protocol to include treatment with COVID-19 specific T cells (MDACC #2017-0350, IND 17761). One of the most severe manifestations of the COVID-19 viral infection is acute respiratory distress syndrome (ARDS), often requiring mechanical ventilation and high dose corticosteroid therapy due to respiratory failure. Indeed, there is increasing evidence that the use of corticosteroids may reduce mortality in patients with COVID- 19 related ARDS, especially if administered early in the treatment algorithm. However, COVID-19 specific T-cell therapy is not an option in such patients as corticosteroids induce apoptosis of adoptively transferred T cells, thus, significantly limiting the efficacy of this approach. To address this challenge, our group has developed an efficient and novel strategy to inactivate the glucocorticoid receptor (GR) in viral-specific T cells, using CRISPR- Cas9 gene editing of the Nuclear Receptor Subfamily 3 Group C Member1 gene (NR3C1- the gene encoding the GR). In Aim 2 of this proposal, we will perform the IND-enabling studies for the production of GMP-grade NR3C1 knockout COVID-19 specific T-cells in preparation for a subsequent phase 1 trial, to be funded through alternative sources. Given our track-record of generatin... ## Key facts - **NIH application ID:** 10162818 - **Project number:** 3R01CA211044-04S1 - **Recipient organization:** UNIVERSITY OF TX MD ANDERSON CAN CTR - **Principal Investigator:** Katy Rezvani - **Activity code:** R01 (R01, R21, SBIR, etc.) - **Funding institute:** NIH - **Fiscal year:** 2020 - **Award amount:** $162,000 - **Award type:** 3 - **Project period:** 2020-07-01 → 2021-06-30 ## Primary source NIH RePORTER: https://reporter.nih.gov/project-details/10162818 ## Citation > US National Institutes of Health, RePORTER application 10162818, Off-the-shelf engineered NK cells for the treatment of AML (3R01CA211044-04S1).
