FDA Clears Abivertinib for Phase 2 Safety and Efficacy Study in Hospitalized Patients With Moderate to Severe COVID-19


SAN DIEGO, July 17, 2020 — ACEA Therapeutics, Inc. today announced that on July 16, 2020, the FDA cleared the IND to initiate a Phase 2 trial of Abivertinib in patients with COVID-19 who have moderate to severe pulmonary symptoms. The Trial, A Phase 2, Double Blinded, Randomized Study of the Efficacy and Safety of STI-5656 (Abivertinib Maleate) With Standard of Care Versus Standard of Care in Subjects Hospitalized With COVID-19 (NCT04440007), will be initially conducted in centers in the USA.

Abivertinib is a novel small molecule tyrosine kinase inhibitor (TKI) that selectively targets both mutant forms of the epidermal growth factor receptor (EGFR) and Bruton’s tyrosine kinase (BTK). ACEA announced an exclusive license of abibvertinib to Sorrento across all indications outside of China on 21MAY2020. ACEA will continue developing abivertinib all indications in China.

Abivertinib irreversibly binds to the BTK receptor, preventing the phosphorylation of the receptor.  Due to this effect, it has shown potent immunomodulatory activities by inhibiting key pro-inflammatory cytokine production, including IL-1beta, IL-6 and TNF-alpha. These cytokines are associated with COVID disease progression and poor outcomes in patients with acute respiratory distress syndrome (ARDS).

Since abivertinib targets multiple cytokines simultaneously, we anticipate the effects with Abivertinib will be incremental to the initial findings of others which primarily reduce IL-6, and the clinical benefits more pronounced given the broader range of anti-cytokine activity.

Abivertinib has been studied in over 600 patients worldwide in various oncologic indications, including one registration trial in non-small cell lung cancer.  Most treatment-related AEs were grade 1 or 2, the most common of which were transaminase elevations and diarrhea, which are generally considered common for TKIs.  Other common treatment-related AEs included anemia, neutropenia and thrombocytopenia, and all generally considered typical AEs with long-term use of TKIs.  No unexpected AEs were reported.
