Updated clinical data from Phase 2 studies evaluating SRF388 in both liver and lung cancer expected in the second quarter of 2023

Projected cash runway guidance remains unchanged with funding into the third quarter of 2024

CAMBRIDGE, Mass., May 04, 2023 (GLOBE NEWSWIRE) -- Surface Oncology (Nasdaq: SURF), a clinical-stage immuno-oncology company developing next-generation immunotherapies that target the tumor microenvironment, today reported financial results and corporate highlights for the first quarter 2023, as well as anticipated near-term milestones.

“We remain highly encouraged by the progress of our two clinical programs, SRF388 a potential first-in-class IL-27 inhibitor, and SRF114, a potentially best-in-class anti-CCR8 antibody, both of which have been enrolling well,” said Rob Ross, M.D., chief executive officer of Surface. “At the recent AACR Annual Meeting, we presented compelling new SRF114 preclinical data which indicate that therapeutic depletion of CCR8 positive tumor infiltrating Tregs results in robust anti-tumorigenic activity across multiple tumor models. With respect to SRF388 and our ongoing Phase 2 trials in liver and lung cancer, we look forward to providing a clinical data update in both indications later in the second quarter.”

First Quarter and Subsequent Corporate Highlights

In April 2023, Surface presented new preclinical data on SRF114, a fully human anti-CCR8 antibody, at the American Association for Cancer Research (AACR) Annual Meeting 2023 in Orlando. A poster presentation highlighted new in vivo data showing SRF114 promotes a pro-inflammatory tumor microenvironment resulting in robust antitumor activity in checkpoint inhibition-resistant and checkpoint inhibition-susceptible tumor models. The poster also demonstrated that anti-CCR8 therapy resulted in the depletion of Treg cells selectively in tumor tissue and anti-CCR8 and anti-PD-1 combination therapy increased tumor immune cell infiltration, cytokine production and improved overall survival in a checkpoint inhibitor-resistant melanoma model.
In January 2023, Surface announced the first patient had been dosed in a Phase 1/2 study evaluating SRF114 as a monotherapy in patients with advanced solid tumors. The dose escalation portion of the study is ongoing and will enroll up to 30 patients evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of SRF114.

Selected Anticipated Near-term Corporate Milestones

In the second quarter, Surface expects to share updated clinical data from the ongoing Phase 2 studies investigating SRF388 as a monotherapy in lung cancer and in combination therapy in liver cancer.
Initial safety and efficacy data from the ongoing SRF114 Phase 1/2 clinical study are anticipated in 2024.

Financial Results

As of March 31, 2023, cash, cash equivalents and marketable securities were $102.1 million, compared to $124.8 million on December 31, 2022.

General and administrative (G&A) expenses were $5.9 million for the first quarter ended March 31, 2023, compared to $6.5 million for the same period in 2022. The decrease primarily relates to personnel-related costs from reduced headcount and a reduction in professional fees. G&A expenses included $1.0 million in stock-based compensation expense for the first quarter ended March 31, 2023.

Research and development (R&D) expenses were $13.8 million for the first quarter ended March 31, 2023, compared to $16.6 million for the same period in 2022. This decrease was primarily driven by a reduction in manufacturing costs for our SRF388 program and the strategic decision to pause the SRF617 program as part of our corporate restructuring in November 2022. R&D expenses included $0.6 million in stock-based compensation expense for the first quarter ended March 31, 2023.

For the first quarter ended March 31, 2023, net loss was $19.7 million, or basic and diluted net loss per share of $0.33. Net income was $6.2 million for the same period in 2022, or basic net income per share of $0.13 and diluted net income per share of $0.13.

Surface Oncology continues to project that current cash and cash equivalents are sufficient to fund the company into the third quarter of 2024.

About SRF388

SRF388 is a fully human anti-IL-27 antibody designed to inhibit the activity of this immunosuppressive cytokine. Surface Oncology has identified particular tumor types, including liver and lung cancer, where IL-27 appears to play an important role in the immunosuppressive tumor microenvironment and may contribute to resistance to treatment with checkpoint inhibitors. SRF388 targets the rate-limiting p28 subunit of IL-27, and preclinical studies have shown that treatment with SRF388 blocks the immunosuppressive biologic effects of IL-27, resulting in immune cell activation in combination with other cancer therapies including anti-PD-1 therapy, as well as potent anti-tumor effects as a monotherapy. Furthermore, Surface Oncology has identified a potential biomarker associated with IL-27 that may be useful in helping to identify patients most likely to respond to SRF388. In November 2020, Surface announced that SRF388 was granted Orphan Drug designation and Fast Track designation for the treatment of refractory hepatocellular carcinoma from the FDA.

About SRF114

SRF114 is a fully human, afucosylated anti-CCR8 antibody designed to preferentially deplete CCR8+ Treg cells within the tumor microenvironment. In preclinical studies, Surface Oncology has shown that SRF114 induces antibody-dependent cellular cytotoxicity (ADCC) and/or antibody-dependent cellular phagocytosis (ADCP) pathways to deplete intratumoral Treg cells. In addition, SRF114 reduced tumor growth in murine models. These findings support the advancement of SRF114 as a therapeutic candidate that holds the potential to drive anti-tumor immunity in patients.

About Surface Oncology

Surface Oncology is an immuno-oncology company developing next-generation antibody therapies focused on the tumor microenvironment. Its pipeline includes two wholly-owned programs; SRF388, a Phase 2 program which targets IL-27, and SRF114, a Phase 1 program, which selectively depletes regulatory T cells in the tumor microenvironment via targeting CCR8. In addition, Surface has two partnerships with major pharmaceutical companies: a collaboration with Novartis targeting CD73 (NZV930; Phase 1) and a collaboration with GlaxoSmithKline targeting PVRIG (GSK4381562, formerly SRF813; Phase 1). Surface’s novel, investigational cancer immunotherapies are designed to achieve a clinically meaningful and sustained anti-tumor response and may be used alone or in combination with other therapies.
