Broadening our impact

Radioligand therapies have the opportunity to fundamentally transform the way we treat cancer, becoming a new standard of care that combines the precision of targeted therapies with the power of radiation to yield highly effective treatments that limit unwanted side effects. Maximizing the full potential of radioligand therapies for a broad range of cancers starts with identifying the right targets.

DLL3

Our lead program targets DLL3, a cell-surface protein widely expressed across a range of cancers, with limited expression on healthy cells. This selective expression makes DLL3 an ideal target for treating these aggressive cancers, which today have poor survival rates.

Targeting DLL3 offers potential to address indications such as small cell lung cancer, gastroenteropancreatic neuroendocrine tumors, neuroendocrine prostate cancer, and large cell neuroendocrine carcinoma

B7-H3

Our second program targets B7-H3, which is highly expressed across many types of cancer and correlates with poor patient survival and prognosis. B7-H3 has been shown to promote tumor cell proliferation and metastases and help tumor cells evade the immune system.

Targeting B7-H3 brings additional pan-tumor targeting potential to Mariana Oncology’s pipeline

Discovery programs

Our selection of novel targets and innovative approach to designing compounds and radioligand therapies fuel a robust portfolio of early-stage programs, each with the potential to address a broad range of cancers. Lead candidates are engineered for selective target binding, tumor penetration, and rapid clearance of unbound molecules for treatments with high impact on tumors and minimal unwanted side effects.

In addition to targeting DLL3 and B7-H3, Mariana Oncology is advancing a robust portfolio of early-stage programs each with the potential to address a broad range of cancers

We're strategically pursuing cancer targets that unlock the full potential of radioligand therapy. By taking an innovative, tailored approach to drug design and development for each high-impact target, we aim to precisely deliver radiation where it matters most, expanding the therapeutic reach of radioligand therapies across multiple cancer types of unmet need.”
