Synthetically Engineered Bacteria for the Treatment of Solid Tumors

Saltikva® completed a Phase 2 clinical trial in Stage 4 pancreatic cancer, increasing median overall survival by 75% and progression-free survival by 162%* versus the historical standard of care.

* Patients receiving >5 doses of Saltikva vs. historical FFX controls. Median OS 20.3 vs 11.6 mo; PFS 15.0 vs 5.7 mo.

Mechanism

From oral dose to tumor cell death.

Saltikva® is a synthetically engineered agent built on a Salmonella chassis, designed for efficacy and safety. Scroll to follow the seven steps of its proposed mechanism, based on preclinical studies.

  1. Step 01 · Oral Administration

    Saltikva® is orally administered as a liquid suspension.

  2. Step 02 · Migration

    Saltikva® migrates from the gut directly to solid tumors.

  3. Step 03 · Homing

    They gather and grow inside solid tumors.

  4. Step 04 · Replication

    Saltikva® replicates and produces active human IL-2 inside the tumor, designed to limit systemic exposure.

  5. Step 05 · Activate

    Saltikva® stimulates the immune system to impart a tumor cell kill and also likely competes with the tumor for nutrients.

  6. Step 06 · Contact

    An NK cell touches a tumor cell’s surface and releases toxic granules at the point of contact.

  7. Step 07 · Tumor Kill

    A multifactorial approach imparts a tumor cell kill.

Why Saltikva®

Saltikva® is an orally administered investigational cancer therapy. No serious adverse event has been attributed to Saltikva® in clinical studies to date, and it has shown anti-cancer activity in multiple preclinical and clinical studies.
