A Platform for Tumor-Specific Immune Cytokines (TsIC)

Our mission is to revolutionize cancer treatment with breakthrough Tumor-Specific Immune Cytokines, turning the promise of total tumor clearance and lifelong immune protection from a laboratory concept into clinical reality.

CytoCan Platform

Innovative Technologies

Novel platform technologies for producing immune cytokines that target cancer cells or the tumor microenvironment, designed to induce tumor-specific immunity and eliminate tumors.

MISSION

CytoCan is devoted to developing life-changing Tumor-specific Immune Cytokines (TsICs) to help patients fight cancer. We envision a near future where tumors can be completely eliminated by TsICs, and patients can be protected by immunity specific to cancer.

PLATFORM

We have developed a novel modular platform technology for producing immune cytokines that target cancer cells or the tumor microenvironment (TME). By precisely delivering immune cytokines to specific components of the TME, such as PD-1+ T cells, we aim to stimulate these T cells with TsICs to eliminate cancer cells while minimizing the risk of unintended systemic side effects.

INNOVATION

Probiokine: A proprietary platform anchored by a humanized IgG-binding domain. Functional antibody-like proteins can be expressed in bacteria or probiotic strains.

PD-1-Targeting Cytokines: Our technology integrates an optimized PD-1 antibody, precisely binding PD-1 epitopes and carrying potency-optimized cytokines.

PRECISION

We identify unmet medical needs and address difficult-to-treat cancers by designing targeted immune cytokines to eliminate cancer cells. By delivering these treatments specifically to tumor microenvironments, this new class of therapies maximizes tumor-killing efficacy while minimizing systemic and unintended side effects.

Next-Gen PD-1 Inhibitors

Our TsICs represent the next generation of PD-1 inhibitors. They not only block the PD-1/PD-L1 interaction but also deliver immunocytokines with optimized activity to the tumor microenvironment to enable selective activation of effector T cells.

Preclinical Success

In preclinical studies, our PD-1-targeted pipeline candidates have demonstrated complete responses in animal tumor models, achieving complete remission of drug-resistant tumors.

About CytoCan

CytoCan is an innovative biopharmaceutical company focused on the research and development of tumor-specific immune cytokines (TsIC). Its core pipeline product is a recombinant TsIC targeting PD-1, positioned as the next generation of PD-1 inhibitor, specifically designed for cancer patients with PD-1 resistance.

By targeting PD-1, this product not only blocks the PD-1/PD-L1 interaction but also delivers immunocytokines with optimized activity to the tumor microenvironment (TME) to enable the selective activation of effector T cells. By integrating these three mechanisms of action, this TsIC has achieved complete remission of drug-resistant tumors in mouse models and is expected to overcome the clinical limitations of current PD-1 inhibitors in the future.

The company is currently advancing Investigational New Drug (IND) application preparations, with plans to submit dual IND applications in China and the United States within 18 months.

Frequently Asked Questions

What are Tumor-Specific Immune Cytokines (TsICs)?

TsICs are engineered fusion proteins that combine tumor-targeting antibodies with immune-stimulating cytokines. They deliver immune activation directly to the tumor microenvironment, enhancing anti-tumor responses while reducing systemic toxicity.

How does CytoCan’s PD-1 TsIC differ from existing PD-1 inhibitors?

Unlike traditional PD-1 inhibitors that only block immune checkpoints, our TsICs block PD-1 while simultaneously delivering optimized cytokines to re-activate T cells directly within the tumor, offering a triple mechanism of action.

What cancers are being targeted?

Our lead programs focus on PD-1 inhibitor-resistant solid tumors, HER2-positive breast and gastric cancers, and other EGFR- and TROP2-expressing malignancies.
