"Patients with platinum-resistant ovarian cancer have a poor prognosis, and treatment options remain extremely limited, highlighting a substantial unmet need for new therapies," said Jeffrey Stafford, Ph.D., CEO of 858 Therapeutics. "We are pleased that the FDA has granted Fast Track designation to ETX-19477 and we are committed to working closely with the FDA to accelerate its development. This designation was based on preclinical data and emerging clinical data from our ongoing Phase 1/2 trial of ETX-19477, including anti-tumor activity at tolerable doses."

FDA Fast Track status is designed to facilitate the development and expedite the review of new therapies that are intended to treat serious conditions with unmet medical need. Under the Fast Track designation, the ETX-19477 development program will have access to more frequent interactions with the FDA and may be eligible for accelerated approval and/or priority review if certain criteria are met.

ETX-19477 is being evaluated in an ongoing Phase 1/2, open-label, multicenter study in patients with advanced solid tumors, designed to assess safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity. The trial is currently enrolling patients in Phase 1 backfill cohorts at multiple dose levels and enriching for select solid tumors harboring BRCA mutations, including HGSOC.

About ETX-19477

Poly(ADP-ribose) glycohydrolase (PARG) is an enzyme that catalyzes the removal of poly-ADP-ribose (PAR) chains from proteins during the DNA damage response. PARG inhibition leads to selective cell death in tumors with underlying replication fork defects, including BRCAm tumors, through a mechanism distinct from PARP inhibition. ETX-19477 is an oral, potent, and selective PARG inhibitor that shows robust preclinical activity in mouse models of ovarian, breast, and gastric cancers. 858 Therapeutics is evaluating ETX-19477 in a Phase 1/2 study in patients with advanced solid tumors at multiple sites in the U.S. For more information on the Phase 1/2 study, please visit: View Source

Additionally, after successfully clearing the second dose cohort, the Phase 1 trial evaluating the Company’s epidermal growth factor receptor (EGFR)-targeted antibody-drug conjugate (ADC) ALX2004 for the treatment of EGFR-expressing solid tumors has begun enrolling patients in the third dose cohort at 4mg/kg. No dose-limiting toxicities were observed in the prior two dose cohorts.

"We are extremely pleased with the progress we are making on these clinical trials," said Jason Lettmann, Chief Executive Officer at ALX Oncology. "We believe both evorpacept and ALX2004 have the potential to fill significant gaps in the standard of care for many types of cancer."

Evorpacept is the first CD47 inhibitor to show substantial tumor response and a well-tolerated safety profile in a randomized trial. Data from this prior gastric cancer trial, ASPEN-06, show that evorpacept demonstrated benefit across all efficacy parameters in patients with HER2-positive disease and high CD47 expression levels. Research has demonstrated that increased CD47 expression is correlated with poor patient outcomes in many tumor types, including breast cancer.

The Phase 2 ASPEN-09-Breast clinical trial (NCT07007559) is a single-arm, open-label, multicenter study evaluating evorpacept plus trastuzumab and physicians’ choice of chemotherapy in 80 patients with HER2-positive breast cancer previously treated with ENHERTU (fam-trastuzumab deruxtecan-nxki), which was recently approved as first-line therapy. The trial will utilize participants’ CD47 expression levels as a biomarker to assess responses.

The primary endpoint of the trial is overall response rate (ORR) in patients who are confirmed HER2 positive by circulating tumor DNA (ctDNA). Key secondary endpoints are ORR in the HER2 ctDNA+ subpopulation by level of CD47 expression, clinical benefit rate (CBR), duration of response (DOR), progression-free survival (PFS) and overall survival (OS), and safety. ORR in the HER2 ctDNA-negative subpopulation is an exploratory endpoint. ALX Oncology anticipates sharing interim data from the trial in Q3 2026.

The ALX2004 Phase 1 clinical trial (NCT07085091) is a first-in-human, open-label, multicenter trial evaluating ALX2004 in participants with advanced or metastatic select EGFR-expressing solid tumors. The study consists of a Phase 1a dose escalation portion followed by optional dose exploration, and a Phase 1b dose expansion. The dose escalation portion of the trial is enrolling patients with previously treated advanced or metastatic non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), esophageal squamous cell carcinoma (ESCC) and colorectal cancer (CRC).

"Preclinical data suggest that ALX2004 has the potential to overcome the toxicity challenges associated with earlier generation EGFR-targeted ADCs," said Lettmann. "It is encouraging that, after clearing the second dose cohort in our Phase 1 trial at 2mg/kg, we are able to double the dosage to 4mg/kg in the third cohort."

ALX Oncology expects to provide an initial safety update from the Phase 1 ALX2004 trial during 1H 2026.

The company also announced the submission of an IND for HWK-016, its MUC16-targeted ADC, to the FDA in December 2025. A Phase 1 trial is anticipated to start recruiting this quarter and is expected to initially evaluate activity in two high MUC16-expressing gynecologic cancers, ovarian and endometrial.

Both next-generation ADC programs leverage Whitehawk’s advanced ADC technology platform consisting of a highly stable yet cleavable linker that delivers a DNA Topoisomerase I (TOP1) inhibitor payload. Whitehawk expects to report initial clinical data from these trials in early 2027.

"These are important regulatory and execution milestones, underscoring the strength of our preclinical data and our ability to advance multiple programs in parallel," said Dave Lennon, PhD, President and CEO of Whitehawk Therapeutics. "At Whitehawk, we are taking a unique approach to the development of next-generation ADCs, combining validated tumor biology with a differentiated ADC architecture. Our platform’s design features are intended to maximize tumor targeting while minimizing off-target toxicity, enabled by highly selective antibodies, a stabilizing bioconjugation strategy that includes carbon-bridge cysteine re-pairing, and controlled delivery of a potent TOP1 inhibitor payload. As our lead programs enter the clinic, our focus will be on efficient clinical execution to generate data that validates this approach with meaningful outcomes for patients."

About HWK-007
HWK-007 is a differentiated next-generation ADC targeting Protein Tyrosine Kinase 7 (PTK7). PTK7 is an oncofetal transmembrane pseudokinase that drives early embryonic development, has restricted expression in adult tissues and frequent overexpression in a wide range of cancers. PTK7 is the third most highly expressed tumor marker among clinically validated and emerging ADC targets, present in ~70% of tumors. There are no approved PTK7-directed ADCs.

HWK-007-101 is a Phase 1, multicenter, open-label study in adult participants that will employ a sequential dose-escalation and expansion design to evaluate the safety, pharmacokinetics and preliminary antitumor activity of HWK-007 in participants with advanced or metastatic solid tumors that are refractory to standard therapies.

About HWK-016
HWK-016 is a differentiated next-generation ADC targeting the membrane-bound portion of Mucin 16 (MUC16). MUC16 is a glycoprotein with low level of expression in normal adult tissues, and broad overexpression in gynecological tumors including ovarian, cervical and endometrial. In ovarian cancer, for example, MUC16 is present at rates up to 3-10 times higher than clinically validated and emerging ADC targets.

Shed MUC16 (CA125) is a validated biomarker for cancer screening and disease monitoring in gynecologic cancers. When ADCs bind to this cleaved portion of the MUC16 protein in circulation, it is cleared from the patient systemically rather than reaching the tumor. HWK-016 is designed to overcome this by directly targeting the membrane-bound, non-shed portion of MUC16.

HWK-016-101 is a planned Phase 1, multicenter, open-label study in adult participants that will employ a sequential dose-escalation and expansion design to evaluate the safety, tolerability, pharmacokinetics and preliminary antitumor activity of HWK-016 in participants with advanced or metastatic solid tumors that are refractory to standard therapies.
