The article outlines a significant clinical trial phase and partnership that could lead to commercialization, directly affecting DNTH's stock through market confidence and projected revenues.
Why Long Term?
With concrete clinical trial timelines and expected results in 2026, investors should see long-term growth potential similar to other biotech stocks like Moderna, which ramped up during key trial phases.
Leads Biolabs and Dianthus Therapeutics Launch Phase 1 Trial of LBL-047 (DNTH212)
Nanjing Leads Biolabs Co., Ltd. (9887.HK) in partnership with Dianthus Therapeutics, Inc. (Nasdaq: DNTH), has announced the successful dosing of the first subject in their Phase 1 clinical trial of LBL-047 (DNTH212). This investigational bifunctional fusion protein is being evaluated for its potential as a first-line biologic therapy for autoimmune disorders, including systemic lupus erythematosus (SLE). The study shows promise for addressing unmet medical needs in immunotherapy.
Overview of the Phase 1 Trial
The Phase 1 trial, designed as a two-part, double-blind, randomized, placebo-controlled, dose-escalation study, aims to assess the safety, tolerability, and pharmacokinetics/pharmacodynamics (PK/PD) of LBL-047 in both healthy volunteers and patients with SLE.
- Part A involves healthy volunteers, led by Professor Meng Xianmin at Shanghai Public Health Clinical Center.
- Part B focuses on patients with SLE, overseen by Professors Ye Shuang and Chen Sheng at Renji Hospital, Shanghai Jiaotong University School of Medicine.
Results from the healthy volunteer segment are anticipated in the second half of 2026, while updates on prioritized indications will be provided by Dianthus in the first half of the same year.
The Mechanism Behind LBL-047 (DNTH212)
LBL-047 (DNTH212) is engineered to target both the innate and adaptive immune systems, specifically focusing on plasmacytoid dendritic cells (pDCs) via BDCA2 to diminish Type 1 interferon production. This dual-targeting approach also inhibits B-cell activating factor (BAFF) and APRIL, thereby controlling B-cell function. This mechanism positions LBL-047 as a leading candidate among biologic therapies for autoimmune conditions.
Key features of LBL-047 (DNTH212) include:
- First-class anti-BDCA2/TACI fusion protein with potential for advanced efficacy.
- Optimized for patient-friendly subcutaneous self-administration.
- Dosing frequency of every four weeks (Q4W) or less.
Strategic Partnership Goals
On October 16, 2025, Leads Biolabs and Dianthus entered into an exclusive global licensing agreement for LBL-047 (DNTH212), with a potential total deal value of up to $1 billion. Under this partnership, Dianthus has secured global rights to research, develop, manufacture, and commercialize LBL-047 (DNTH212) outside of Greater China. This collaboration aims to maximize both the clinical and commercial potential of the drug.
Expert Insights on LBL-047 (DNTH212)
Dr. Charles Cai, Chief Medical Officer at Leads Biolabs, expressed optimism regarding the trial, stating, “We are pleased to announce the successful dosing of the first subject in our Phase 1 trial of LBL-047. By simultaneously targeting multiple pathways, LBL-047 is designed to address the limitations of single-target therapies.”
Dr. Simrat Randhawa, Head of Research & Development at Dianthus Therapeutics, added, “Initiating this Phase 1 study is the first step to realizing the anticipated outcomes of targeting multiple dysfunctional pathways in autoimmune diseases.”
