Atossa Therapeutics Reports Second Quarter 2026 Financial Results and Provides a Corporate Update
SEATTLE, WASHINGTON, August 7, 2026 — Atossa Therapeutics, Inc. (Nasdaq: ATOS) (Atossa or the Company), a clinical-stage biopharmaceutical company developing novel therapies in oncology and other areas of high unmet clinical need, today announced its financial results and provided an update on recent corporate developments for the second quarter ended June 30, 2026.
“During the quarter, we executed well across the business,” stated Dr. Steven Quay, M.D., Ph.D., Atossa Therapeutics’ President and Chief Executive Officer. “We continued to advance the scientific rationale for (Z)-endoxifen’s potential in rare pediatric diseases, such as Duchenne Muscular Dystrophy and McCune-Albright Syndrome, while also strengthening its clinical and scientific foundation in breast cancer, all through new data presented at important industry conferences, including ASCO and AACR, as well as publications in well-regarded peer-reviewed journals, Degenerative Neurological and Neuromuscular Disease and npj Breast Cancer.”
Dr. Quay continued, “These accomplishments, together with additional capital from our registered direct offering, underscore the breadth of potential we see for (Z)-endoxifen, and investors’ support in our ability to continue advancing our programs.”
Second Quarter 2026 & Recent Highlights
Rare Diseases
• Atossa Participated at the 2026 American Association for Cancer Research (AACR) Special Conference in Cancer Research: Cancer Evolution
o In a poster presentation titled, “Dual estrogen receptor and PKC-β signaling modulation by (Z)-Endoxifen: A mechanism-driven therapeutic strategy for estrogen-driven pathology in McCune-Albright Syndrome,” the Company discussed a dual mechanism of action for (Z)-endoxifen in estrogen-driven pathology relevant to McCune-Albright Syndrome-associated Peripheral Precocious Puberty (MAS-PPP).
o The dual mechanism includes the blockade of estrogen receptor (ER)-mediated transcription downstream of autonomous estrogen production and suppression of PKC-β/AKT-associated proliferative and cell-cycle signaling.
o This multi-pathway profile may address a key therapeutic gap in MAS-PPP, where estrogen suppression alone may not fully mitigate downstream proliferative signaling.
o The Company previously received Rare Pediatric Disease (RPD) designation for (Z)-endoxifen from the U.S. Food and Drug Administration (FDA) for (Z)-endoxifen for the treatment of McCune-Albright Syndrome (MAS).
• The Company Announced Acceptance of Manuscript Highlighting the Utrophin-Modulation Potential of (Z)-Endoxifen in Duchenne Muscular Dystrophy (DMD)
o A paper details how (Z)-endoxifen may support the expression of utrophin, a paralog of dystrophin. (Z)-Endoxifen therefore represents a potential dystrophin mutation-agnostic treatment for DMD. The paper citation is: Remmel HL, Hammer SS, Blackburn SM, Quay SC. (Z)-Endoxifen as a Potential Modulator of Utrophin Pathways in Duchenne Muscular Dystrophy: A Mechanistic and Transcriptomic Perspective. Degener Neurol Neuromuscular Dis. 2026;16:574524 https://doi.org/10.2147/DNND.S574524
o The results support further investigation of (Z)-endoxifen in dystrophin-deficient models, as well as biomarker development. These data also build upon the Company’s previously published manuscript, “A Hypothesized Therapeutic Role of (Z)-Endoxifen in Duchenne Muscular Dystrophy,” also published in Degenerative Neurological and Neuromuscular Disease.
o The Company previously received Orphan Drug Designation (ODD) and RPD designation for (Z)-endoxifen from the FDA for the treatment of DMD.
Oncology
• The Company Published Manuscript Highlighting the Anti-cancer Activity of (Z)-Endoxifen-related Compounds
o In the peer-reviewed journal, npj Breast Cancer, the Company published an article titled, “Novel (Z)-endoxifen-related new chemical entities exhibit potent anti-cancer activity in ERα+ breast cancer.”
o The investigators evaluated five previously uncharacterized compounds generated during the synthesis of (Z)-endoxifen, alongside (Z)-endoxifen in a broad panel of laboratory assays, as well as in combination with the CDK4/6 inhibitor abemaciclib.
o The publication reported anti-estrogenic and anti-cancer activity across multiple ER-positive (ER+) breast cancer models, including models harboring clinically relevant activating mutations in ESR1.
o In certain experimental settings and models, selected compounds combined with abemaciclib demonstrated additive to synergistic activity that was comparable to or greater than the activity observed with abemaciclib plus (Z)-endoxifen.
o The authors concluded that select compounds warrant further in vivo safety evaluation, as well as efficacy studies, including as potential second- or third-line approaches for recurrent disease.
