About Cyana Therapeutics

Cyana Therapeutics is a precision immuno-oncology company developing drugs to treat solid tumors. Our lead compound (CY-3132) is a small molecule inhibitor of an enzyme called ENPP1, which is upregulated on the surface of many tumor cells. ENPP1 activity allows tumor cells to evade the immune system, and tumors expressing high levels of ENPP1 are often resistant to current cancer treatments. By blocking ENPP1 activity, CY-3132 restores cancer cell immune signaling, activating the body's ability to recognize and eliminate cancer cells.

The Role of ENPP1 in Tumor Cell Immune Evasion

The ENPP1 enzyme is part of the cGAS-STING pathway, which controls immune signaling in the body. High ENPP1 expression level on tumor cells allows the tumor to evade the body's immune system. ENPP1 expression on tumor cells has been correlated with low survival rates in cancer patients.

Blocking ENPP1 in tumor cell lines and animal models increases survival and improves response to cancer treatments by turning “cold” tumors into “hot” tumors that the body can recognize and target.

Comparison of tumor cell immune evasion versus treatment with CY-3132. Left: ENPP1 degrades tumor signals, suppressing immune activation. Right: CY-3132 blocks ENPP1, allowing immune cells to recognize and eliminate cancer.

Solid Tumor Types with High ENPP1 Expression

High expression of ENPP1 is seen in multiple solid tumor types, including:

  • Liver
  • Pancreatic
  • Breast
  • Colorectal
  • Glioblastoma
  • Sarcoma
  • Lung
  • Kidney
  • Head & Neck
  • Stomach
  • Esophageal
  • Bladder
  • Bile Duct
  • Uterine
  • Ovarian
  • Cervical
  • Melanoma
  • Thymoma
  • Lymphoid
  • Adrenocortical
  • Thyroid
  • Adrenal
  • Testicular
  • Prostate

Advancing ENPP1 inhibitors for cancer immunotherapy

Cyana Therapeutics pipeline: CY-3132 (SC Injection) targeting ENPP1 for Oncology in IND-Enabling with Phase 1 in 2026; CY-3292 (Oral) targeting ENPP1 for Rare Disease in Lead Optimization.
IND Open

Lead Program: CY-3132

CY-3132 is a small molecule inhibitor of ENPP1 for the treatment of solid tumors. By blocking ENPP1 activity, CY-3132 transforms tumor cells from immune evading to immune activating. CY-3132 has been tested in many solid tumor cell lines and animal models that have traditionally been resistant to treatment, including breast cancer, colorectal cancer, pancreatic cancer and lung cancer.

Status
IND open
Phase 1a/1b clinical trial planned for 2026 in patients with refractory solid tumors
Trial will evaluate CY-3132 as a standalone therapy and in combination with a checkpoint inhibitor (nivolumab)
Next Milestone
Phase 1a/1b safety and efficacy data (overall survival, progression-free survival, objective response rate)
