SHAOXING, China, May 9, 2026 /PRNewswire/ -- Recently, the novel oral BET inhibitor NHWD-870 HCI, independently developed by Zhejiang Wenda Pharmaceutical Technology Co., Ltd., officially received Breakthrough Therapy Designation from the China National Medical Products Administration (NMPA) for the proposed indication of advanced thoracic midline (NUT) carcinoma in patients who have failed prior chemotherapy. This milestone progress brings new targeted therapy hope to NUT carcinoma patients, a disease with extremely high malignancy and a very poor prognosis.

NUT carcinoma is a rare, poorly differentiated carcinoma characterized by NUTM1 gene rearrangement. The disease progresses rapidly, with a median survival of only approximately 6.5 months. It commonly occurs in the lungs, head, and neck regions, and the median age of onset is only 23.6 years. Due to the lack of specificity in clinical manifestations and insufficient awareness among the public, the rates of misdiagnosis and missed diagnosis are extremely high, and most patients are already at an advanced stage at the time of diagnosis. Currently, no effective targeted drug for NUT carcinoma has been approved globally, and the treatment landscape is extremely dire.

The granting of Breakthrough Therapy Designation to NHWD-870 HCI is primarily based on the significant efficacy and survival benefits demonstrated in its Phase II clinical study. As of December 27, 2025, a total of 40 evaluable subjects with advanced NUT carcinoma were enrolled in the study. The data showed that the drug exhibited positive anti-tumor activity across different lesion sites: the objective response rate (ORR) in 20 patients with advanced thoracic NUT carcinoma reached as high as 45.00%; the median overall survival (mOS) for advanced thoracic NUT carcinoma patients and for all subjects both reached 9.33 months, representing a significant extension compared with standard chemotherapy regimens. Currently, some patients are still receiving ongoing treatment and close follow-up. In addition, preliminary safety data showed that the drug was generally well tolerated and held high potential for clinical application.

This Breakthrough Therapy Designation is of great significance for NUT carcinoma patients and represents a leapfrog advance in the field. For patients, it means that the regulatory review process for NHWD-870 HCI will be accelerated and the drug will reach the market sooner, enabling patients with advanced NUT carcinoma to receive targeted therapy earlier and escape the dilemma of having no effective drug, thereby significantly prolonging survival and improving quality of life. On the clinical level, the development and designation of this drug fill the gap in targeted treatment for NUT carcinoma and provide clinicians with a completely new treatment option. This not only drives the transformation of NUT carcinoma treatment from "symptomatic treatment" to "precision targeted therapy" but also provides valuable clinical experience for the future development of similar drugs.

Mr. Nenghui Wang, Founder of Wenda Pharma, stated: "We are delighted that our product has received Breakthrough Therapy Designation. This progress highlights China's growing capabilities in innovative drug development for rare cancers. NHWD-870 not only brings hope to NUT carcinoma patients but also offers new avenues for exploring treatments for other rare malignancies."

Professor YIN Mingzhu, Director of the Midline (NUT) Carcinoma Specialty at the Affiliated Three Gorges Hospital of Chongqing University, noted, "NUT carcinoma once plunged countless patients and doctors into despair. The Breakthrough Therapy Designation for NHWD-870 is an important achievement integrating medical research and clinical practice. In the future, with the accelerated market entry of this drug, the treatment landscape of NUT carcinoma is expected to be completely transformed, injecting new momentum into the cause of rare disease diagnosis and treatment in our country."

Founded in 2013 and headquartered in Shaoxing City, China. Wenda Pharma is a company dedicated to pioneering, innovative, and high-quality drug discovery. The company focuses its research in the areas of oncology, immunology, and neurodegenerative diseases, with multiple Chinese and global patent applications and grants in these fields. Several of the company's drug candidates are currently in Phase I, II, and III clinical trials.

The NHWD-870 program, targeting the rare NUT carcinoma, has successfully completed Phase II clinical trials and holds the potential to become a "First-in-Class" oral small-molecule BET inhibitor, offering patients the hope of extended survival. Additionally, the Company's WD-890 TYK2 (JH2) inhibitor—indicated for moderate-to-severe plaque psoriasis—has entered Phase III clinical trials, while Phase II trials for the systemic lupus erythematosus (SLE) indication are also set to commence shortly. WD-910, a therapeutic candidate targeting neurodegenerative diseases, is poised to enter Phase II clinical trials in China, which just completed phase I clinical trial in Australia, its 100% blood-brain barrier penetration capability positions it as a potential "Best-in-Class" drug candidate. Wenda Pharma boasts a rich and innovative pipeline targeting numerous refractory and incurable diseases, striving to provide patients with more effective, safe, and cost-effective innovative medicines.

Die Weltgesundheitsorganisation (WHO) kommt mit ihrem zentralen Pandemie-Abkommen langsamer voran als geplant. Die Mitgliedstaaten haben sich in Genf darauf verständigt, die Verhandlungen über den sogenannten PABS-Mechanismus – den Annex zu „Pathogen Access and Benefit Sharing“ – zu verlängern. Eigentlich sollte bis Anfang Mai ein Kompromiss vorliegen, der auf der 77. Weltgesundheitsversammlung Ende Mai in Genf beschlossen werden sollte. Stattdessen soll die Versammlung nun formell darüber entscheiden, die Gespräche fortzuführen und den Abschluss erst in den kommenden Jahren ins Visier zu nehmen.

Im Kern geht es um die Frage, wie Daten über neue Krankheitserreger und Informationen zu Impfstoffen, Diagnostika und Therapien bei künftigen Pandemien ausgetauscht werden sollen – und wie die daraus entstehenden Vorteile fair geteilt werden. Der PABS-Mechanismus gilt als Herzstück des internationalen Pandemie-Abkommens, das die WHO-Mitgliedstaaten bereits im Mai 2023 grundsätzlich gebilligt hatten. Die technischen und politisch sensiblen Details des Systems waren damals bewusst ausgeklammert worden, um zunächst eine Grundsatzeinigung zu ermöglichen.

Die Verhandlungsfronten verlaufen vor allem zwischen wohlhabenden Staaten und Entwicklungsländern, die tief gespalten sind, wenn es um die Ausgestaltung des Zugangs zu Erregerproben und die Verteilung von daraus entstehenden Nutzen wie Impfstoffen geht. Länder des Globalen Südens drängen auf verbindliche Zusagen für einen gerechteren Zugang zu medizinischen Gegenmitteln, während Industrienationen und ihre Pharmaunternehmen auf verlässliche Regeln für Datennutzung und geistige Eigentumsrechte achten. WHO-Generaldirektor Tedros Adhanom Ghebreyesus sprach dennoch von „realem Fortschritt“ beim PABS-Anhang und zeigte sich zuversichtlich, dass Differenzen mit weiteren Gesprächen überbrückt werden können.

Die Ergebnisse der jüngsten Verhandlungsrunde der zwischenstaatlichen Arbeitsgruppe (IGWG) zum Pandemieabkommen sollen der 79. Weltgesundheitsversammlung vorgelegt werden. Angesichts des zusätzlichen Gesprächsbedarfs soll die Versammlung laut WHO darüber entscheiden, das Mandat der Arbeitsgruppe auf Basis der bereits verabschiedeten Resolution WHA78.1 zu verlängern und die Resultate spätestens zur Versammlung im Mai 2027, möglicherweise bereits bei einer Sondersitzung 2026, vorzulegen. Tedros mahnte die Staaten, die offenen Fragen mit „Dringlichkeit“ anzugehen: Die nächste Pandemie sei keine Frage des Ob, sondern des Wann. Erst mit einem abgeschlossenen PABS-Anhang können Länder das Pandemie-Abkommen vollständig unterzeichnen und ratifizieren.
