Locust Walk Acquisition Corp.’s Stockholders Approve Business Combination with eFFECTOR Therapeutics to Create Next-Generation Oncology Company Developing New Class of Cancer Therapies

SAN DIEGO, Aug. 24, 2021 (GLOBE NEWSWIRE) — Locust Walk Acquisition Corp. (NASDAQ: LWAC) (“LWAC” or the “Company”), a special purpose acquisition company, announced today that the Company’s stockholders have approved all proposals related to the previously announced business combination (the “Business Combination”) with eFFECTOR Therapeutics, Inc. (“eFFECTOR”) at a special meeting of stockholders held on August 24, 2021. Approximately 93.2% of the votes cast at the meeting on the Business Combination proposal, representing approximately 71.7% of LWAC’s outstanding shares, voted to approve the Business Combination.

LWAC stockholders also voted overwhelmingly to approve the other proposals at the special meeting.

The Business Combination is expected to close on or about Wednesday, August 25, 2021. Upon closing, the combined company expects that its common stock and public warrants will commence trading on Nasdaq under the new trading symbols “EFTR” and “EFTRW,” respectively, starting on or about Thursday, August 26, 2021.

LWAC received elections to redeem approximately 17.0 million of its outstanding shares, which will leave approximately $5.2 million in its trust account. Combined with the $60.7 million in expected gross proceeds from a concurrent private placement, there will be approximately $65.9 million of total cash proceeds from the transaction. As a result, eFFECTOR has waived the requirement that the total cash proceeds equal or exceed $100.0 million. There will be approximately $53.5 million of net cash available to the combined company from the transaction, after deducting transaction fees and expenses.

eFFECTOR expects that the net cash following the transaction will allow it to readout topline data from the ongoing Phase 2b KICKSTART trial evaluating tomivosertib in combination with pembrolizumab in patients with metastatic non-small cell lung cancer (“NSCLC”), as well as readout initial overall response rate (“ORR”) data from the ongoing Phase 2a dose expansion cohorts evaluating zotatifin in patients with certain biomarker-positive solid tumors, including ER+ breast cancer and KRAS-mutant NSCLC.

About Locust Walk Acquisition Corp.
Locust Walk Acquisition Corp. (NASDAQ: LWAC) is a blank-check company formed for the purpose of entering a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization, or other similar business combination with one or more businesses or entities.

eFFECTOR is a clinical-stage biopharmaceutical company focused on pioneering the development of a new class of oncology drugs referred to as selective translation regulator inhibitors (STRIs). eFFECTOR’s STRI product candidates target the eIF4F complex and its activating kinase, mitogen-activated protein kinase 1/2 (MNK 1/2). The eIF4F complex is a central node where two of the most frequently mutated signaling pathways in cancer, the PI3K-AKT and RAS-MEK pathways, converge to activate the translation of select mRNA into proteins that are frequent culprits in key disease-driving processes. Each of eFFECTOR’s product candidates is designed to act on a single protein that drives the expression of multiple functionally related proteins, including oncoproteins and immunosuppressive proteins in T cells, that together control tumor growth, survival and immune evasion. eFFECTOR’s lead product candidate, tomivosertib, is a MNK 1/2 inhibitor currently being evaluated in KICKSTART, a randomized, double-blind, placebo-controlled Phase 2b trial of tomivosertib in combination with pembrolizumab in patients with metastatic NSCLC. Zotatifin, eFFECTOR’s inhibitor of eIF4A, is currently being evaluated in Phase 2a expansion cohorts in certain biomarker-positive solid tumors, including ER+ breast cancer and KRAS-mutant NSCLC. eFFECTOR has a global collaboration with Pfizer to develop inhibitors of a third target, eIF4E. In addition to the company’s oncology focus, zotatifin is being evaluated as a potential host-directed anti-viral therapy in patients with mild to moderate COVID-19 in collaboration with the University of California, San Francisco, under a $5 million grant sponsored by the Defense Advanced Research Projects Agency.
