The ZFA triplet program showed promising results with a 7.4 month mPFS in heavily pre-treated patients, indicating potential effectiveness in cancer treatment.
The results from the KICKSTART trial were disappointing, leading to a shift in focus and strategy for eFFECTOR Therapeutics.
Despite positive results in the ZFA triplet program, there were still zotatifin-related treatment-emergent adverse events leading to patient discontinuation in some cases.

Dose escalation of zotatifin in the ZFA triplet ongoing at 0.14 mg/kg, with RP2D expected in H2 2024

SOLANA BEACH, Calif. and REDWOOD CITY, Calif., May 09, 2024 (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 first quarter ended March 31, 2024, and provided a corporate update.
“We had a productive first quarter marked by continued progress in the zotatifin program, including successful completion of the ZF doublet dose escalation, and ongoing assessment of increasing doses in the ZFA triplet,” said Steve Worland, Ph.D., president and chief executive officer of eFFECTOR. “We are highly encouraged with the safety profile and activity already reported for the ZFA triplet, in particular the 7.4 month mPFS in heavily pre-treated patients, and look forward to finalizing the dose and schedule in the second half of 2024. We believe the zotatifin program is well positioned to move into a randomized trial later this year.”
Dr. Worland continued: “While we were disappointed in the results from the KICKSTART trial, our commitment to maximizing the value of all assets in our pipeline remains unchanged. Our focus is now further sharpened towards advancing zotatifin through development as efficiently as possible. As part of our strategy to leverage external interest in our clinical programs to conserve capital, we will continue investigator-sponsored trials of zotatifin in ER+ breast cancer in a pre-operative setting and tomivosertib in acute myeloid leukemia (AML). Additionally, with the completion of the registered direct financing in January 2024, extending our cash runway into the first quarter of 2025, we can continue progressing with these planned zotatifin development activities and the initiated ISTs.”
Pipeline Highlights
Zotatifin (eFT226): eFFECTOR’s wholly-owned potent and selective inhibitor of mRNA helicase eIF4A designed to downregulate the expression of key oncoproteins and cell cycle proteins that drive tumor growth and resistance:
- Dose escalation now focused on the ZFA triplet. Based on favorable safety and tolerability results observed in more than 50 patients who received zotatifin at the initial RP2D of 0.07 mg/kg on Days 1 and 8 of a 21-day cycle, as monotherapy, combined with fulvestrant (ZF doublet) or combined with fulvestrant and abemaciclib (ZFA triplet), dose escalation was resumed using a more convenient schedule of zotatifin dosed every other week (Q2W). In the first quarter of 2024, dose escalation of the ZF doublet concluded with the determination of 0.2 mg/kg zotatifin Q2W as the new RP2D for the doublet, which is projected to provide approximately twice the overall zotatifin exposure compared to the initial RP2D. Determination of the RP2D for the ZFA triplet is ongoing, with dosing currently at 0.14 mg/kg and determination of the RP2D anticipated in the second half of 2024. The company looks forward to finalizing the dose and schedule for zotatifin in the ZFA triplet and interacting with the FDA prior to initiating a randomized, potentially registrational, trial in ER+ breast cancer.
- Positive interim Phase 2 data including mPFS of 7.4 months in the ZFA triplet expansion cohort reported at the 2023 San Antonio Breast Cancer Symposium (SABCS®). In the ZFA triplet cohort, wherein patients with a median of four prior lines of therapy for metastatic disease received 0.07 mg/kg zotatifin dosed on Days 1 and 8 of a 21-day cycle, combined with fulvestrant and abemaciclib, the mPFS was 7.4 months (
95% confidence intervals 2.8 to non-estimable). As previously reported, five of 19 (26% ) RECIST-evaluable patients had partial responses, including four confirmed and one unconfirmed. The ZFA triplet continued to be generally well tolerated, with the majority of zotatifin-related treatment-emergent adverse events (TEAEs) being Grade 1 or 2. The most common zotatifin-related TEAEs were nausea, vomiting, and fatigue, all of which were Grade 1 or 2. The most common Grade 3 or higher zotatifin-related TEAEs were anemia and blood creatinine phosphokinase increase, each in two of 20 (10% ) patients. Four of 20 (20% ) patients discontinued treatment due to adverse events of any cause.
- Ongoing patient enrollment in randomized Phase 2 investigator sponsored trial (IST) in ER+ breast cancer. The study is being conducted as part of a collaboration with Stanford Medicine in which zotatifin is being tested in specific genomically-defined subgroups, including standard-risk patients as well as high-risk patients carrying specific markers predictive of relapse. The trial is led by Jennifer Caswell-Jin, M.D., Assistant Professor of Medicine at Stanford Medicine, and brings 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.
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:
- Phase 1 investigator-initiated dose escalation trial in patients with relapsed/refractory Acute Myeloid Leukemia (AML) in collaboration with Northwestern University. Currently enrolling patients, the trial is designed to capitalize on previously published results that showed preclinical activity of tomivosertib in AML models. Once the appropriate dose for tomivosertib in AML is identified, the company hopes to expand the trial to test tomivosertib in combination with venetoclax and azacytidine. The study is led by Shira Dinner, M.D., Associate Professor of Medicine (Hematology and Oncology) at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University.
- Topline results from Phase 2b KICKSTART trial in NSCLC reported in April 2024. The hazard ratio for progression free survival, based on 36 events, was 0.62 (
95% confidence intervals 0.3 and 1.3) using a stratified COX proportional hazards model, with a two-sided p-value for PFS of 0.21, which did not meet the pre-specified threshold of 0.2. Based on the totality of the data available as of the primary analysis, the company does not see an obvious path forward to continue developing tomivosertib in frontline NSCLC.

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. Zotatifin, eFFECTOR’s inhibitor of eIF4A, is currently being evaluated in a Phase 2a expansion cohort in combination with fulvestrant and abemaciclib in ER+ breast cancer. Tomivosertib, eFFECTOR’s MNK inhibitor, is currently being evaluated in an investigator-sponsored trial in AML. eFFECTOR has a global collaboration with Pfizer to develop inhibitors of a third target, eIF4E.
