Leveraging their proprietary Fleximer platform, Mersana is rewriting the rules for immunoconjugate therapies by creating precisely targeted and highly tailored drugs. This platform allows for the custom design of ADCs with specific properties that overcome current limitations and enhance the drug's effectiveness against particular cancers, while minimizing side effects.
Mersana's lead product candidate, Upifitamab Rilsodotin (UpRi), utilizes the Dolaflexin platform and targets the NaPi2b protein, primarily for the treatment of platinum-resistant ovarian cancer. Although the UPLIFT clinical trial did not meet its primary endpoint, the company is conducting in-depth analyses to understand the results and potential future steps for UpRi.
Among its pipeline, Mersana's early-stage programs include XMT-1660, a Dolasynthen ADC targeting B7-H4, and XMT-2056, a STING agonist ADC developed using the Immunosynthen platform, which targets a novel epitope of human epidermal growth factor receptor 2 (HER2). Mersana is advancing XMT-1660 in its Phase 1 clinical trial, with plans to initiate dose expansion in 2024. For XMT-2056, Mersana has resumed enrollment in its Phase 1 clinical trial following the lifting of a clinical hold by the FDA.
Mersana collaborates with multiple partners, such as Janssen Biotech and Merck KGaA, to advance their ADC pipelines using Mersana’s innovative platforms. Additionally, the company continues to strengthen its financial position, reporting substantial cash reserves to support its operations into 2026.
