eFFECTOR Therapeutics Reports Second Quarter 2023 Financial Results and Provides Corporate Update
Positive data update from Phase 2 expansion cohort evaluating zotatifin combined with fulvestrant and abemaciclib (ZFA triplet) in estrogen receptor-positive (ER+) metastatic breast cancer (mBC) presented at the American Society of Clinical Oncology (ASCO) Annual Meeting 2023
Continued progress in dose-escalation study with zotatifin in combination with fulvestrant in ER+ mBC,
with data anticipated in the second half of 2023

SOLANA BEACH, Calif. and REDWOOD CITY, Calif., Aug. 08, 2023 (GLOBE NEWSWIRE) -- eFFECTOR Therapeutics, Inc. (NASDAQ: EFTR), a leader in the development of selective translation regulator inhibitors (STRIs) for the treatment of cancer, today reported financial results for the second quarter ended June 30, 2023 and provided a corporate update.
“It was another productive quarter for eFFECTOR as we made considerable progress on all fronts,” remarked Steve Worland, Ph.D., president and chief executive officer of eFFECTOR. “The data presented at ASCO was a significant milestone for the zotatifin program, with substantially greater activity observed with the ZFA triplet than we would have expected in such heavily pretreated patients with just fulvestrant and abemaciclib. While still immature, we are encouraged by the emerging PFS data for the ZFA triplet and look forward to disclosing mature PFS data along with further dose escalation data later this year. We are now focusing on defining our registrational path for zotatifin in ER+ mBC and believe that the drug can be positioned as a second line therapy in multiple patient segments, with and without defined resistance mutations.”
“The randomized Phase 2b KICKSTART clinical trial of tomivosertib combined with pembrolizumab for the treatment of non-small cell lung cancer (NSCLC) continues to progress, with an anticipated data readout in the second half of 2023,” continued Dr. Worland. “In addition, we are thrilled to welcome Dr. Gary Chiang back to eFFECTOR as the Vice President of Translational Science, as we continue to build up internal expertise to support both tomivosertib and zotatifin development programs. Lastly, we bolstered our balance sheet by raising over
Pipeline Highlights
Tomivosertib (eFT508): eFFECTOR’s wholly owned, highly selective MNK inhibitor designed to enhance anti-tumor immune activity by activating T cells, delaying their exhaustion, and expanding the pool of central memory T cells:
- Enrollment continues in Phase 2b KICKSTART trial in NSCLC. eFFECTOR’s KICKSTART trial is continuing to enroll patients with PD-L1 expression ≥
50% who will receive tomivosertib or placebo in combination with pembrolizumab as their initial therapy for metastatic disease. Topline data are anticipated in the second half of 2023.
Zotatifin (eFT226): eFFECTOR’s wholly-owned, potent and selective inhibitor of mRNA helicase eIF4A designed to downregulate expression of key oncoproteins and cell cycle proteins that drive tumor growth and resistance:
- Positive clinical data for ZFA triplet in ER+ breast cancer was presented at ASCO Annual Meeting 2023 in June, with partial responses seen in
26% of patients. New interim data were presented on the fully enrolled expansion cohort of patients (n=20) who received the ZFA triplet with zotatifin dosed at 0.07 mg/kg on Days 1 and 8 of 21-day cycles. Patients were heavily pre-treated, having received a median of four prior lines of therapy for metastatic disease. Five out of 19 (26% ) RECIST-evaluable patients achieved a partial response (PR), including four confirmed and one unconfirmed. All five patients who achieved a PR had previously progressed on prior CDK4/6 and fulvestrant treatments, and all five had received one or more prior lines of chemotherapy. Efficacy results exceeded our expectations for fulvestrant and abemaciclib (FA doublet) in such heavily pre-treated patients after CDK4/6, endocrine and/or chemotherapies. The ZFA triplet was generally well tolerated, with three patients discontinuing due to adverse events (AEs) of any cause, and the large majority of AEs being Grade 1 or 2. Mature PFS data from the ZFA cohort is anticipated in the second half of 2023.
- On track to report topline data from dose escalation in the second half of 2023. Favorable safety results generated to date have allowed resumption of dose escalation to determine the recommended Phase 2 dose of zotatifin combined with fulvestrant (ZF doublet). Topline data from dose escalation are anticipated in the second half of 2023.
- Collaboration with Stanford Medicine on investigator-initiated randomized Phase 2 study in patients with ER+ breast cancer. This trial, being led by Jennifer Caswell-Jin, M.D., Assistant Professor of Medicine at Stanford Medicine, is bringing to the clinic the science of integrative subgroups of breast cancer, building on work done by Christian Curtis, Ph.D., Professor of Medicine, Genetics, and Biomedical Data Science, and Director of Artificial Intelligence and Cancer Genomics at Stanford Medicine. Zotatifin will be tested in specific genomically-defined subgroups, including standard risk patients as well as high-risk patients carrying specific markers predictive of relapse.
Business Highlights
$16.2 million in gross proceeds raised from two registered direct financings, extending cash runway into second quarter of 2024. eFFECTOR completed two registered direct financings during the second quarter of 2023. The first financing closed on May 31, 2023, and included the sale of an aggregate of 11,450,382 shares of common stock (or common stock equivalents in lieu thereof), at a purchase price of$0.65 5 per share (or common stock equivalent in lieu thereof), and unregistered warrants to purchase up to an aggregate of 11,450,382 shares of common stock with an exercise price of$0.53 per share. The second financing closed on June 8, 2023, and included the sale of an aggregate of 7,764,445 shares of common stock (or common stock equivalents in lieu thereof), at a purchase price of$1.12 5 per share (or common stock equivalent in lieu thereof), and unregistered warrants to purchase up to an aggregate of 7,764,445 shares of common stock with an exercise price of$1.00 per share. With the completion of the two financings, eFFECTOR has extended the previously anticipated cash runway from first quarter of 2024 into the second quarter of 2024.

About eFFECTOR Therapeutics
eFFECTOR is a clinical-stage biopharmaceutical company pioneering the development of a new class of oncology drugs referred to as STRIs. eFFECTOR’s STRI product candidates target the eIF4F complex and its activating kinase, mitogen-activated protein kinase interacting kinase (MNK). 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 a network of 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 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 non-small cell lung cancer (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.
