Transcenta Shows Promising Results with Osemitamab for Cancer

Transcenta Reveals Encouraging Results for Osemitamab

Transcenta Holding Limited (HKEX: 06628), a biopharmaceutical company dedicated to innovative antibody-based therapeutics, announced remarkable efficacy outcomes from its ongoing trials involving Osemitamab (TST001) in combination with Nivolumab and CAPOX in patients suffering from advanced gastric or gastroesophageal junction (G/GEJ) cancer. The findings were presented at a prominent medical congress, signaling a notable step forward in cancer treatment.

Impressive Efficacy Data from Cohort G

Recent data unveiled a confirmed Objective Response Rate (ORR) of 68% and a median Progression-Free Survival (PFS) of 14.2 months among patients exhibiting high or medium levels of CLDN18.2 expression. This update follows earlier encouraging data discussed at another major conference earlier this year.

The updated study outcomes relied on a cohort of 66 patients with known CLDN18.2 and PD-L1 scores, showcasing a significant mPFS of 14.2 months for participants showing H/M CLDN18.2 expression levels. A clear advantage was seen in this patient population compared to those with very low or absent CLDN18.2 expression, demonstrating the promising applicability of this treatment framework.

Exploration of Triple Combination Therapy

This trial was significant as it strategically evaluated the safety and efficacy of a triple combination therapy, examining how Osemitamab (TST001) interacts with Nivolumab and CAPOX for first-line treatment in advanced G/GEJ cancers. Notably, the study included patients whose profiles were HER2 negative or unknown and unfit for surgical intervention.

Strong Mechanism of Action

The encouraging data supports the synergistic nature of Osemitamab and immune checkpoint inhibitors, revealing a unique interaction where CLDN18.2 targeting antibodies can influence PD-L1 expression in tumor cells. This interaction further extends T-cell infiltration in gastric cancer cells, promoting an enhanced response to the combined treatment.

Manageable Safety Profile Observed

Across the study, treatment-related adverse events were encountered, primarily mild to moderate in nature, including hypoalbuminemia and nausea. This manageable profile emphasizes the potential for widespread application of this therapy amongst patients.

Clinical Evidence and Future Directions

As of the data cutoff, ongoing improvements in OS were observed, supporting the methodology and underscoring the promise reflected in the studied cohort. Notably, the survival rates and response metrics cement the potential role of Osemitamab in transforming treatment modalities for advanced G/GEJ cancer diagnoses.

Transcenta aims to continue its promising trajectory of growth and innovation, expanding its portfolio and clinical trials through technology platforms designed to enhance the effectiveness of its therapeutic agents.
