"We look forward to ERAS-007 being evaluated in this trial, based in part on ERAS-007’s ability in preclinical studies to robustly shut down oncogenic signaling," said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. "This trial not only helps to broaden the therapeutic development of ERAS-007, but also complements the patient subgroups within our ongoing HERKULES-2 and HERKULES-3 master protocols. Additionally, it may provide proof-of-concept data supporting the addition of ERAS-007 as a treatment option to overcome RAS/MAPK resistance with KRAS G12C inhibitors. We look forward to potentially partnering with the team to explore the therapeutic potential of this combination."

Ryan Corcoran, M.D., Ph.D., Director of the Gastrointestinal Cancer Center Program at Massachusetts General Hospital and Associate Professor of Medicine at Harvard Medical School, added, "While adaptive feedback mechanisms can overwhelm MEK inhibitors, ERK inhibitors potentially can overcome drug resistance mechanisms that involve reactivation of RAS/MAPK pathway signaling. We look forward to evaluating whether the ERK1/2 inhibitor ERAS-007 has the potential to overcome feedback mechanisms and help address the limited efficacy of single agent KRAS G12C inhibitors."

A Phase 1b clinical proof-of-concept trial will evaluate ERAS-007 in combination with a KRAS G12C inhibitor in patients with NSCLC and CRC harboring a KRAS G12C mutation. Additional preclinical and clinical laboratory research will be conducted to further understand the activity and safety of this combination in these patient populations. The trial will be led by principal investigators Scott Kopetz, M.D., Ph.D., Professor of Gastrointestinal Medical Oncology at The University of Texas MD Anderson Cancer Center, Dr. Corcoran, and Pasi Janne, M.D., Ph.D., Professor of Medicine at Harvard Medical School. Drs. Corcoran and Kopetz recently received a grant from Stand Up To Cancer (SU2C).

About ERAS-007
ERAS-007 is a potential best-in-class ERK1/2 inhibitor being investigated alone or in combination with different inhibitors targeting upstream nodes of the MAPK pathway as part of Erasca’s MAPKlamp strategy. The extracellular signal-regulated kinases (ERK), ERK1 and ERK2, belong to a family of serine-threonine kinases that regulate cellular signaling and comprise the terminal node of the RAS/MAPK pathway. The broad therapeutic potential of ERAS-007 is being investigated initially across four HERKULES clinical trials that span multiple tumor types and include both monotherapy and combinations with approved and investigational agents, such as RTK, SHP2, RAS, RAF, and/or cell cycle inhibitors. HERKULES-1 is a Phase 1b/2 clinical trial for ERAS-007 as a single agent and in combination with the SHP2 inhibitor ERAS-601 in advanced solid tumors. HERKULES-2 is a Phase 1b/2 clinical trial for ERAS-007 in combination with various agents in patients with non-small cell lung cancer. HERKULES-3 is a Phase 1b/2 clinical trial for ERAS-007 in combination with various agents in patients with gastrointestinal cancers. HERKULES-4 is a Phase 1b/2 clinical trial for ERAS-007 in combination with various agents in patients with hematologic malignancies.

The multicenter ACTIVATE study is designed to evaluate the efficacy, safety, tolerability, PK, and pharmacodynamics of etigilimab, in combination with nivolumab, with dosing every two weeks.

As of the cut off date of April 20, 2022, there were 38 efficacy-evaluable subjects with a minimum of 1 staging scan or documented clinical progression. Treatment of etigilimab in combination with nivolumab has shown preliminary efficacy across multiple tumor types with 2 complete responses (CRs), 4 partial responses (PRs), and 10 stable disease (SDs) for an overall response rate (ORR) of 15.8% and disease control rate (DCR) of 42.1% in heavily pre-treated, CPI-naïve subjects. Additionally, 7 subjects with clinical benefit remained on study treatment for ≥ 18 weeks. Clinical benefit was noted in tumor types not typically responsive to immune checkpoint inhibitor monotherapy. The combination of etigilimab and nivolumab has been safe and well tolerated, with no new treatment-related SAEs or safety signals observed to-date.

"We are very pleased with these updated results from the ACTIVATE study and look forward to sharing our findings at ASCO (Free ASCO Whitepaper)," said Dr. Suba Krishnan, Senior Vice President, Clinical Development of Mereo. "We are encouraged by the results reported as of the cut-off date, especially the early efficacy noted in cervical cancer, where we have seen two complete responses and two cases of stable disease among five subjects, and in uveal melanoma subjects in the rare tumor cohort, where we saw one partial response and two stable disease with over 20 weeks on study treatment. While these early data are encouraging for our differentiated clinical strategy, we will continue to monitor emerging clinical data on other anti-TIGIT therapeutics as we determine the most appropriate path forward for etigilimab."

Updated Capital Allocation and Portfolio Prioritization Plan
Mereo also announced the outcome of a review to update its capital allocation strategy, including general and administrative and other costs, and portfolio prioritization in light of current market conditions and recent industry clinical data announcements. This review was undertaken with the aim of maximizing shareholder value. Based on these initiatives, the Company now expects its current cash runway will be extended from "into" 2024 to late 2024.

The portfolio, in order of development stage, is as follows:

Setrusumab for Osteogenesis Imperfecta (OI): As planned, Mereo will target its investment toward the activities required in support of the EU and UK territories and the ongoing collaboration with Ultragenyx Pharmaceutical, Inc. The Phase 2/3 in 5-25 year olds has been initiated by Ultragenyx and an update on the Phase 2 is expected before the end of 2022.
Alvelestat for Alpha-1-Anti-Trypsin Deficiency (AATD): Mereo recently announced positive top-line data from the Phase 2 study of alvelestat in AATD. The Company intends to complete further analysis of the Phase 2 data during 2H 2022 and will evaluate further options for the program once it has completed an end-of-Phase 2 meeting with the FDA (intended by end of 2022) and an EMA scientific advisory meeting (thereafter). As previously planned, no additional clinical development expense will be incurred for this program from the current cash resources.
Etigilimab in Oncology: Mereo intends to complete enrollment in the Phase 1b part of the previously planned Phase 1b/2 study in Q3 2022. The Company will then evaluate further options based on the Phase 1b data and external factors, including clinical data from other anti-TIGIT programs.
Mereo will continue to explore a range of additional financing options for its programs, including partnerships, which may include retention of certain rights and/or territories, as well as non-dilutive financing.

"We conducted this strategic review over the last few months in light of current market conditions and emerging external clinical data, to focus the Company’s resources on our lead programs," said Dr. Denise Scots-Knight, Chief Executive Officer of Mereo. "As a result of our updated capital allocation plan, our current cash balance of $111.4 million (as of March 31, 2022) will now support our operating runway into late 2024. We believe this puts Mereo in a stronger position to maximize shareholder value and deliver on multiple milestones over the next two years as we focus on our mission of developing transformative therapies."

In the Phase 2 expansion portion of the ongoing Phase 1-2 study of ST101, 14 GBM patients have been enrolled to date. Of these 14 patients, one patient has a confirmed PR after 18 weeks of therapy, seven patients have not reached the first on-study assessment, and six patients progressed. In both the Phase 1 and Phase 2 portions of the ongoing study, ST101 has demonstrated a favorable safety profile, with manageable mild-moderate infusion related reactions as the most common adverse event. Based on the confirmed PR announced today, Sapience intends to expand the recurrent GBM cohort to enroll additional patients.

"ST101 is showing promising results in GBM with a PR, which we have confirmed with repeat scans per mRANO and using an independent radiology reviewer. The tumor shrinkage we are seeing is especially encouraging given the significant unmet medical need in this disease and its poor prognosis," said Fabio Iwamoto, Principal Investigator at Columbia University. "Our team at Columbia is thrilled to be a part of this work and to deliver meaningful therapeutic benefit to cancer patients."

Dr. Alice Bexon, Sapience’s Chief Medical Officer, added, "The confirmed response in GBM is very exciting news, which along with the continuing clinical benefit we are seeing from some of the Phase 1 patients, suggests that ST101 could make a major contribution to the treatment of cancer. Based on its novel mechanism of action, ST101 is the first in a new class of peptide therapeutics, and we look forward to advancing our Phase 2 study."

Data from the ST101 Phase 1 study will be presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting on Sunday, June 5th, 2022, Abstract #3014.

About ST101 and the Phase 1-2 Study

ST101, a first-in-class antagonist of C/EBPβ, is currently being evaluated in the Phase 2 portion of an ongoing Phase 1-2 clinical study in patients with advanced unresectable and metastatic solid tumors (NCT04478279). ST101-101 is an open-label, two-part, Phase 1-2 dose-finding study designed to determine the safety, tolerability, PK, PD, and proof-of-concept efficacy of ST101 in patients with advanced solid tumors. The study consists of two phases: Phase 1 dose escalation/regimen exploration and Phase 2 expansion. In the ongoing dose escalation study, ST101 has demonstrated clinical proof-of-concept with a durable RECIST 1.1-confirmed partial response (PR) in a patient with cutaneous melanoma and evidence of long-lasting stable disease in several additional patients. In the ongoing Phase 2 dose expansion part of the study, ST101 has demonstrated clinical proof-of-concept with a confirmed partial response in a patient with recurrent GBM. Sapience is actively enrolling patients with GBM, metastatic cutaneous melanoma, locally advanced or metastatic hormone-receptor positive breast cancer and castration-resistant prostate cancer. ST101 has been granted Fast Track designation for recurrent GBM and advanced cutaneous melanoma in patients who have disease progression on or after anti-PD-1/anti-PD-L1 therapy, as well as orphan designations from the FDA for advanced melanoma, glioma and AML, and from the European Commission for the treatment of glioma.
