Mabwell's Breakthrough Monoclonal Antibody 9MW3811 Approved for Clinical Trials Targeting Pathological Scarring

Mabwell's Anti-IL-11 Monoclonal Antibody 9MW3811

Mabwell, a leading innovative biopharmaceutical firm, has taken a significant step forward in the battle against pathological scarring. This novel anti-IL-11 monoclonal antibody, known as 9MW3811, has recently received approval from the China National Medical Products Administration (NMPA) to initiate a Phase II clinical trial. This positions 9MW3811 as the world's first therapeutic targeting interleukin-11 (IL-11) to advance into clinical testing for this specific indication.

Understanding the Significance of 9MW3811

IL-11, a key cytokine involved in both chronic inflammation and fibrosis, plays a major role across various organs such as the lungs, skin, kidneys, and liver. Mabwell's 9MW3811 is a humanized monoclonal antibody that has been developed to specifically bind to IL-11, providing a powerful means to inhibit the erroneous activation of the IL-11/IL-11Rα signaling pathway. This inhibition is crucial in preventing the pathological progression of diseases related to fibrosis.

Advantages of 9MW3811

One standout feature of 9MW3811 is its high target affinity, along with an impressive capability to block signaling pathways associated with IL-11. Further enhancing its therapeutic profile, 9MW3811 boasts a long half-life of over one month, making it particularly effective for chronic conditions that necessitate sustained treatment.

Preclinical studies have indicated that 9MW3811 excels in a variety of models, particularly in treating pulmonary fibrosis. Additionally, its potential extends to other fibrosis-related scenarios such as hypertrophic scars and abnormal endometrial bleeding. Notably, research using human-derived keloid animal models has demonstrated the ability of 9MW3811 to substantially diminish skin fibrosis and reduce scar volumes.

Following successful Phase I trials conducted in Australia and China involving healthy volunteers, which confirmed the safety and lengthy half-life of the treatment, 9MW3811 is on a path to reaching patients who suffer from advanced malignant tumors and idiopathic pulmonary fibrosis (IPF). The Phase II trials focusing on pathological scarring are anticipated to commence by the end of 2025.

Implications for Aging and Chronic Conditions

The relevance of IL-11 extends into the realm of aging-related diseases. A recent article in Nature (2024) points out the connection between IL-11 and the emergence of age-related diseases. With this in mind, Mabwell has partnered with CALICO Life Sciences, a division of Alphabet that specializes in innovative anti-aging therapies, granting an exclusive license for 9MW3811. Beyond its applications in fibrotic diseases affecting multiple organs (including IPF, thyroid eye disease, skin fibrosis, and more), 9MW3811 shows promising potential in addressing conditions associated with cellular senescence, age-related frailty, and even healthspan extension.

The Challenge of Pathological Scarring

Pathological scarring, which comprises hypertrophic scars, keloids, and contracture scars, is profoundly influenced by IL-11-mediated transformations of fibroblasts into myofibroblasts. This process is accompanied by an increase in extracellular matrix components and α-smooth muscle actin (α-SMA), as documented in the study "CD39 Fibroblasts Enhance Myofibroblast Activation by Promoting IL-11 Secretion in Hypertrophic Scars" published in the Journal of Investigative Dermatology (2022). Effective targeting of IL-11 can lead to reduced numbers of α-SMA positive fibroblasts, ultimately halting the progression of scarring.

According to estimates from Frost & Sullivan, there are around 25 million individuals suffering from pathological scars globally, with approximately 7.4 million in China alone. This number is projected to exceed 10 million by 2030, underscoring the significant clinical and market value of therapies aimed at IL-11.

Conclusion

Mabwell is committed to innovating in the field of biopharmaceuticals with its overarching mission: "Explore Life, Benefit Health.” With the advancement of 9MW3811, the company aims to pave the way for transformative treatments in the management of pathological scarring and related chronic conditions.
