The three abstracts cover pioneering research being conducted by Enara Bio in collaboration with leading immunology and MR1 research groups at Monash University and the University of Oxford towards the identification and validation of cancer-specific MR1 ligands and the development of MR1-targeted T-cell receptor cell therapies (TCR-T).

MR1 is an unconventional antigen-presenting molecule that presents metabolites to the immune system in the context of cancer and infection. The monomorphic nature of MR1 strongly suggests that therapies based on MR1-displayed antigens could be effective across the entire human population. These unique properties make MR1 a promising target for off-the-shelf, HLA-independent, TCR-based immunotherapies for solid tumors.

The first presentation, from Enara scientists, highlights the progress the Company is making with its lead autologous MR1-targeting TCR-T program. The two other presentations, led by scientists from Jamie Rossjohn’s and Tony Purcell’s groups at the Monash Biomedicine Discovery Institute (BDI), and Nicola Ternette’s group at the University of Oxford’s Nuffield Department of Medicine, describe novel immunopeptidomic and metabolomic methods to identify and characterize the cancer-specific MR1 ligandome.

Joe Dukes, Vice President, Head of Research at Enara Bio, commented: "We are very pleased to be presenting important abstracts at the upcoming CD1-MR1 EMBO meeting, which showcase the continued developments we are making in partnership with our world-class collaborators to advance the next generation of cancer immunotherapies designed to treat a broad patient population. We have made remarkable progress in our mission to characterize unconventional immunotherapy targets, such as ligands presented by MR1, which we hope will enable development of a pipeline of product candidates that can be advanced into clinical development."

Details of the poster presentations (which will be available on the Company website at the time of the meeting) are as follows:

"The first quarter of 2022 marked the beginning of a data-rich year for Surface, starting with the presentation of preclinical and translational SRF388 data at AACR (Free AACR Whitepaper) in April," said Rob Ross, M.D., chief executive officer. "We are actively developing two novel antibodies in Phase 2 studies, SRF388 and SRF617, and our runway now provides us with 12 months of cash beyond data readouts for up to six different indications and combination studies across the programs. We look forward to presenting our next update on SRF388, the only antibody targeting IL-27 in the clinic, at ASCO (Free ASCO Whitepaper), and we remain on track to share new clinical data for SRF617 in the second half of this year."

First Quarter and Subsequent Corporate Highlights

During the first quarter, Surface raised net proceeds of approximately $21 million through the company’s existing At-the-Market (ATM) facility with participation based on unsolicited interest received from EcoR1 and Octagon Capital Advisors.

At the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2022, Surface presented SRF388 preclinical and translational data supporting the recommended Phase 2 monotherapy dose selection of 10 mg/kg administered intravenously every four weeks. This dose is being studied in dedicated expansion cohorts of treatment-refractory clear cell renal cell carcinoma (ccRCC), non-small-cell lung cancer (NSCLC), and hepatocellular carcinoma (HCC).

In March, Surface announced that the first patient had been dosed by GlaxoSmithKline (GSK) in a Phase 1 study evaluating GSK4381562 in patients with solid tumors. GSK4381562 is a fully human IgG1 antibody targeting PVRIG, an inhibitory protein on the TIGIT/DNAM/TACTILE axis that is expressed on natural killer cells (NK cells) and T cells. As a result, Surface is entitled to a $30 million milestone payment and is eligible to receive an additional $700 million in potential future milestone payments, and tiered royalties on global net sales.

In March, the company announced the appointment of Theresa Boni, J.D., as general counsel and senior vice president, legal. Ms. Boni brings more than 20 years of legal experience spanning the biopharmaceutical and medical device industries.
SRF388 Clinical Trial Progress and Updates

In April 2022, Surface announced the initiation of two Phase 2 clinical studies evaluating SRF388, a potential first-in-class antibody against IL-27. The initiations include the first patient dosed in a Phase 2 monotherapy clinical study in treatment-refractory NSCLC patients and the first patient dosed in the lead-in to a randomized Phase 2 clinical study in combination with atezolizumab and bevacizumab in patients with HCC who have not received prior systemic treatment (first-line).

With respect to the design of the SRF388 randomized Phase 2 study in first-line HCC, the company will expand the open-label lead-in from six patients, as originally planned, to approximately 30 patients. Management believes this expanded lead-in will provide more robust safety and efficacy data to inform the start of the randomized stage and could elucidate important biomarkers to support enriched patient selection. Data from the lead-in are anticipated in the first half of 2023.

New clinical data on SRF388 will be presented in an oral session at the 2022 ASCO (Free ASCO Whitepaper) Annual Meeting. The session, entitled "First-in-human study of SRF388, a first-in-class IL-27 targeting antibody, as monotherapy and in combination with pembrolizumab in patients with advanced solid tumors," will be held Saturday, June 4, 2022, from 1:15 pm – 4:15 pm CDT.
Selected Anticipated Near-term Corporate Milestones

The company remains on track to provide a clinical data update on SRF617, a fully human antibody designed to inhibit CD39, in the second half of 2022.

Surface anticipates filing an Investigational New Drug application for SRF114, a fully human IgG1 anti-CCR8 antibody, in the second half of 2022.

"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.

The decrease of $13.0 million in revenue during the quarter ended March 31, 2022 was primarily the result of a $10.3 million decrease in revenue recognized under the Servier Agreement subsequent to full satisfaction of the performance obligation under the execution of the Program Purchase Agreement in April 2021, a $2.1 million decrease in revenue recognized under the Lilly Agreement, and a $0.6 million decrease in revenue recognized from an agriculture partnering collaboration.

Research and Development Expenses: Research and development expenses were $20.0 million for the quarter ended March 31, 2022, as compared to $25.6 million for the same period in 2021. 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.
