TL;DR
Leads Biolabs has filed an Investigational New Drug (IND) application for its PD-L1/4-1BB bispecific antibody, aiming to treat metastatic colorectal cancer. This marks a significant step toward clinical trials and potential new therapy options.
Leads Biolabs has officially submitted an IND application for its PD-L1/4-1BB bispecific antibody, aiming to initiate clinical trials for metastatic colorectal cancer. This development advances the company’s gastrointestinal oncology portfolio and marks a key milestone in its immunotherapy pipeline.
The IND submission was announced by Leads Biolabs on March 2024, signaling the company’s readiness to begin human testing of its novel bispecific antibody. The therapy combines targeting of PD-L1, an immune checkpoint, with 4-1BB, a co-stimulatory receptor, to potentially enhance anti-tumor immune responses.
According to the company, this bispecific antibody is designed to improve efficacy over existing monotherapies by simultaneously engaging immune checkpoints and co-stimulatory pathways, which could offer a new treatment avenue for patients with metastatic colorectal cancer resistant to current therapies.
While the IND approval is a significant step, the company has not yet disclosed specific trial timelines or detailed clinical development plans. The submission is under review by regulatory authorities, and approval to proceed with human trials remains pending.
Potential Impact on Colorectal Cancer Treatment Landscape
This IND application represents a critical step toward introducing a novel immunotherapy for metastatic colorectal cancer, a disease with limited effective treatment options. If clinical trials demonstrate safety and efficacy, this bispecific antibody could become part of the next generation of cancer immunotherapies, potentially improving patient outcomes and expanding therapeutic options.
The approach of combining immune checkpoint blockade with co-stimulatory activation is gaining interest in oncology, and Leads Biolabs’ progress indicates growing industry confidence in bispecific antibody strategies to overcome resistance seen with current treatments.

Advancement of Bispecific Antibodies in Oncology Trials
Leads Biolabs’ IND submission follows a broader industry trend of developing bispecific antibodies targeting immune pathways, which aim to enhance anti-tumor immune responses. The company’s focus on gastrointestinal cancers aligns with its existing pipeline and research focus.
Previously, the company has made progress in preclinical models, demonstrating promising immune activation and tumor suppression. The IND filing signals a transition from preclinical to clinical development, a crucial milestone in drug development.
Regulatory agencies like the FDA typically review IND applications within 30 days, after which the company can initiate clinical trials if approved. The outcome of this review remains pending at this stage.
“The IND submission marks a significant milestone in our commitment to developing innovative immunotherapies for metastatic colorectal cancer.”
