Locust Walk Acquisition Corp.
PROPOSED BUSINESS COMBINATION: eFFECTOR Therapeutics, Inc.
ENTERPRISE VALUE: $419 million
ANTICIPATED SYMBOL: EFTR
Locust Walk Acquisition Corp. proposes to combine with eFFECTOR Therapeutics, Inc., a biopharmaceutical company focused on pioneering the development of selective translation regulation inhibitors (STRIs) for the treatment of cancer.
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 messenger RNA 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. KICKSTART, a randomized, double-blind, placebo controlled Phase 2b trial of tomivorsertib in NSCLC in combination with pembrolizumab is currently open for enrollment. Zotatifin, eFFECTOR’s inhibitor of eIF4A, is currently in the dose-escalation portion of a Phase 1/2 trial, with Phase 2a expansion cohorts expected to initiate in the second half of 2021. eFFECTOR has a global collaboration with Pfizer to develop inhibitors of a third target, eIF4E. eFFECTOR plans to evaluate zotatifin as a potential host-directed anti-viral therapy in patients with mild to moderate COVID in collaboration with University of California, San Francisco, under a $5 million grant sponsored by the Defense Advanced Research Projects Agency.
Proceeds from the transaction are expected to provide eFFECTOR with the capital to further develop its pipeline, advancing it through multiple clinical milestones, including the following:
- Report topline data from the randomized Phase 2b KICKSTART clinical trial of eFFECTOR’s lead product candidate, tomivorsertib, an oral small-molecule inhibitor of mitogen-activated protein kinases 1 and 2 (MNK) 1/2, in combination with pembrolizumab in metastatic non-small cell lung cancer (NSCLC), both in the frontline extension and frontline settings; this study is open for enrollment.
- Initiate multiple Phase 2a expansion cohorts for zotatifin, a small-molecule inhibitor of eIF4A, in patients with breast cancer and NSCLC in the second half of 2021.
- Support expansion of both tomivosertib and zotatifin into additional indications.
TRANSACTION
- Upon the closing of the business combination, and assuming no redemptions of shares of LWAC by its public stockholders, eFFECTOR would be expected to have cash resources of approximately $210 million (less any redemptions), and a total enterprise valuation of $419 million.
- The transaction includes up to $175 million in trust at LWAC (less any redemptions by existing LWAC stockholders) and a concurrent, fully committed $60 million PIPE financing of common stock issued at $10.00 per share from new and existing leading healthcare investors including founding Series A investors Abingworth, SR One, The Column Group and U.S. Venture Partners, as well as Altitude Life Science Ventures, Sectoral Asset Management, Pfizer Ventures, Alexandria Venture Investments, BioMed Ventures and Osage University Partners.
