Mesothelioma, Treatment Landscape, and Macrophage-Solid Tumor Dynamics

Mesothelioma is one of the deadliest solid cancers with few treatment options, all of which have limited efficacy. People who are most at risk to develop mesothelioma generally have had long-term exposure to asbestos (e.g., construction workers, pipe fitters, and shipyard workers). It takes many years for mesothelioma to develop; it can appear 30 years after asbestos exposure. Immune checkpoint inhibitors targeting CTLA4 and PD1 are FDA-approved as first-line treatments for patients with unresectable malignant pleural mesothelioma.

In mesothelioma and in some other solid cancers, tumor cells, as part of their defense mechanisms, facilitate the recruitment of macrophages which become "pro-tumor" tumor associated macrophages (TAMs) rather than "anti-tumor" macrophages. The TAMs typically form a physical layer on top of the solid tumor, and induce immunosuppression in the solid tumor microenvironment. This in-turn promotes tumor growth and metastasis and makes it very difficult for the immune system or any anti-cancer drug to efficiently attack the cancerous cells. Allocetra is a cell therapy in development that is targeted at these TAMs, and its proposed mechanism of action is to change the balance of macrophage populations to skew towards anti-tumor macrophages and away from pro-tumor macrophages.

The Mesothelioma Model

To test the potential effect of cell therapy-induced macrophage reprogramming on difficult-to-treat solid tumors, Enlivex ran preclinical studies in which five groups of mice were implanted with mesothelioma cancer cells. The difference between the groups was the treatment given, which started on day 12 after the cancer’s initial growth period.

Results from multiple studies strongly support the potential of AllocetraTM to assist in the process of macrophage reprogramming in the solid tumor microenvironment and significantly change survival outcomes. As expected, only 1/16 (6%) of the untreated mice remained alive at day 42 (that one last remaining mouse died on day 65), compared with up to 25% survival for the mice in the group that was treated with the anti-CTLA4 immune checkpoint inhibitor. Surprisingly, AllocetraTM as a stand-alone treatment provided comparable survival rates as anti-CTLA4 monotherapy, with a 28.5% survival rate and a delayed cancer growth rate observed. Notably, the synergistic effect of treating with both drugs resulted in up to 100% survival with complete disappearance of the cancer. The effect was correlated with the AllocetraTM treatment dose. A lower dose of AllocetraTM provided slightly lower survival and cancer complete remission rates (67% complete remission for the low-dose treatment vs. up to 100% for the higher dose). The following chart provides a visual guide to the progressions/regression of the mesothelioma cancer in the different groups, as recorded for study mesothelioma AB12 137:

Across multiple studies of the AB12 mesothelioma model, anti-CTLA4 therapy significantly improved survival duration from mean 34±9 to 44.9 ±20 days (p<0.05). Allocetra as a stand-alone therapy improved survival duration to 52.3 ±20 days (p<0.02). The synergistic effect of the combination therapy of anti-CTLA4 + AllocetraTM improved survival duration to 86.7±20 days (p<0.0001) with complete cancer remission in 60-100% of mice, depending on the dose administered.

Prof. Dror Mevorach, Chief Scientific Officer of Enlivex, stated: "This reproducible and statistically significant data strongly support Allocetra’s proposed therapeutic mechanism of action of reprogramming macrophages in solid tumors. We believe that, in contrast to CAR-T, CAR-NK and other anti-cancer cell therapies directed at tumor antigens, AllocetraTM restores macrophage homeostasis in the tumor environment via reprogramming of pro-tumor macrophages. This may ultimately allow immune checkpoint inhibitors to be exponentially more effective."

Oren Hershkovitz, Ph.D., CEO of Enlivex, added: "Based on these results, Enlivex is planning to initiate a series of clinical trials during 2022 that are designed to evaluate Allocetra in combination with FDA-approved immune checkpoint inhibitor therapies in patients with advanced-stage solid tumors. To date, we have infused AllocetraTM in dozens of hospitalized patients in fragile condition resulting from sepsis and COVID-19-related organ dysfunction. We believe that the proposed differentiated mechanism of action of AllocetraTM, together with the safety and tolerability it has demonstrated in these prior studies, as well as the encouraging efficacy results of our preclinical solid tumor models, highlight an intriguing opportunity for Enlivex to provide another layer of life-saving therapy for patients who have few available options."

ABOUT ALLOCETRA

Allocetra is being developed as a universal, off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. Diseases such as solid cancers, sepsis, and many others reprogram macrophages out of their homeostatic state. These non-homeostatic macrophages contribute significantly to the severity of the respective diseases. By restoring macrophage homeostasis, Allocetra has the potential to provide a novel immunotherapeutic mechanism of action for life-threatening clinical indications that are defined as "unmet medical needs", as a stand-alone therapy or in combination with leading therapeutic agents.

About CTX001
CTX001 is an investigational, autologous, ex vivo CRISPR/Cas9 gene-edited therapy that is being evaluated for patients suffering from TDT or severe SCD, in which a patient’s hematopoietic stem cells are edited to produce high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is a form of the oxygen-carrying hemoglobin that is naturally present at birth, which then switches to the adult form of hemoglobin. The elevation of HbF by CTX001 has the potential to alleviate or eliminate transfusion requirements for patients with TDT and reduce or eliminate painful and debilitating sickle crises for patients with SCD. Earlier results from these ongoing trials were published as a Brief Report in The New England Journal of Medicine in January of 2021.

Based on progress in this program to date, CTX001 has been granted Regenerative Medicine Advanced Therapy (RMAT), Fast Track, Orphan Drug, and Rare Pediatric Disease designations from the U.S. Food and Drug Administration (FDA) for both TDT and SCD.

"We continue to focus on execution and build on the utility of ARCUS as a premier genome editing platform to develop novel treatments for cancer and genetic diseases. We believe the differentiated attributes of ARCUS enable a high degree of specificity, minimal levels of off-target editing and maximum versatility, including gene insertion. These qualities underpin our organic strategy and attract accomplished partners that extend our reach to more patients with serious diseases while also providing capital to advance our core development priorities," said Michael Amoroso, Chief Executive Officer at Precision BioSciences. "As our programs continue to mature, we will remain nimble and follow the data to prudently manage our portfolio. This will allow us to hone in on the most impactful approaches to develop potential allogeneic CAR T product candidates and pursue optimal strategies for delivery to various tissues for gene editing in vivo."

"As we look ahead, we plan to provide an update across our allogeneic CAR T programs in June 2022 as data matures. On the research front, we have initiated IND-enabling studies for PBGENE-PH1 delivered by LNP as we target advancing three wholly owned in vivo gene editing programs towards IND or CTA applications over the next three years," Mr. Amoroso continued.

Recent Developments and Upcoming Milestones:

Ex Vivo Allogeneic CAR T Portfolio:

PBCAR0191: PBCAR0191 is the Company’s lead investigational anti-CD19 allogeneic CAR T candidate being evaluated in a Phase 1/2a clinical trial of adult subjects with relapsed or refractory (R/R) non-Hodgkin lymphoma (NHL). In December 2021, Precision announced a Phase 1 data update, in which a 100% overall response rate (6/6) and a 66% complete response rate (4/6) was observed among patients that previously received an autologous CAR T therapy and progressed. Precision prioritized enrollment of this high unmet need patient population as a potential path for PBCAR0191, and the Company plans to provide a program update on PBCAR0191 in June 2022.
PBCAR19B: PBCAR19B is a novel, immune-evading stealth cell candidate employing a single-gene edit to knock-down beta-2 microglobulin and insert an HLA-E transgene. We believe PBCAR19B is the first CAR T cell candidate in the clinic designed to evade rejection by host T cells and natural killer (NK) cells. Precision initiated a clinical trial of PBCAR19B in patients with NHL in mid-2021 and plans to commence dosing in the third quarter of 2022 at the next dose level with clinical trial material from an optimized manufacturing process. The Company plans to provide a program update on PBCAR19B in June 2022.
PBCAR269A: PBCAR269A is an investigational allogeneic CAR T cell candidate targeting B-cell maturation antigen (BCMA) for R/R multiple myeloma. Precision is evaluating PBCAR269A in a Phase 1/2a study in combination with nirogacestat, a gamma secretase inhibitor developed by SpringWorks Therapeutics. The first patient was dosed in the combination arm in June 2021, and Precision expects to provide a program update on PBCAR269A in June 2022.
In Vivo Gene Editing Portfolio:

Over the next three years, Precision expects that three of its wholly owned preclinical in vivo programs will advance to IND or CTA. This includes:

PBGENE-PCSK9: In 2021, Precision initiated a collaboration with iECURE, pursuant to which Precision’s PBGENE-PCSK9 candidate is expected to advance through preclinical activities as well as a Phase 1 study in familial hypercholesterolemia. A CTA filing is expected as early as the end of 2022.
PBGENE-PH1: Precision has initiated IND-enabling activities for its PBGENE-PH1 candidate designed to knock out the well-validated HAO1 gene as a potential one-time treatment for primary hyperoxaluria type 1 (PH1). In the first quarter of 2022, the Company initiated a non-human primate study for PBGENE-PH1 delivered by LNP and expects to submit an IND or CTA in 2023.
PBGENE-HBV: Precision’s gene editing program for chronic Hepatitis B applies ARCUS to knock out persistent covalently closed circular DNA (cccDNA) and inactivate integrated hepatitis B genomes, potentially achieving durable HBV S-antigen (HBsAg) loss and viral persistence. Precision plans to pursue clinical development of its PBGENE-HBV candidate using LNP delivery and expects to submit an IND/CTA in 2024.
Precision continues its in vivo gene editing collaboration with Lilly and is applying ARCUS nucleases for three initial targets, including Duchenne muscular dystrophy in muscle, a central nervous system directed target and a liver directed target. In addition, Precision continues to engage discussions with potential biotech collaborators to leverage the unique attributes of ARCUS, such as gene insertion, for a variety of disease targets.

As announced on May 2, 2022, preclinical data on Precision’s wholly owned PH1 and HBV programs will be presented at the upcoming American Society of Gene and Cell Therapy (ASGCT) (Free ASGCT Whitepaper) meeting, May 16-19, 2022.

The decrease of $5.6 million was primarily due to decreases of $2.7 million in external development costs, including clinical research organization and clinical manufacturing organization costs, associated with our PBCAR0191, PBCAR269A, PBCAR20A and PBCAR19B clinical trials, as well as decreases of $1.1 million in sublicensing royalty payable to Duke on the Lilly upfront payment that was received in 2021 and $1.4 million in employee-related costs due to reduced headcount driven by the separation of Elo in 2021.

General and Administrative Expenses: General and administrative expenses were $10.7 million for the quarter ended March 31, 2022, as compared to $9.5 million for the same period in 2021. The increase of $1.2 million was primarily due to costs required to meet our growing infrastructure needs, including an increase of $1.3 million in general and administrative employee-related costs associated with increased wages, share-based compensation, relocation and recruiting costs for key management personnel.
