Cancer treatment has been revolutionized by antibody drug conjugates (ADCs) as they’ve offered patients therapy that targets mainly cancer cells while avoiding the systemic release of cancer-killing toxic payloads, like systemic chemotherapy, throughout the body. Linkers play a critical role in the function of ADCs as they help to attach the cytotoxic payload to the antibody, stabilize the molecule during circulation, and release the toxic payload specifically into the target tissue¹. Multilink is a new cleavable linker platform that allows the loading of multiple drug payloads on an antibody. Degraducer is a powerful, bifunctional, inhibitor technology that enables selective protein degradation and prolonged therapeutic effects. Combining these advanced biotechnology solutions offers the unique opportunity to produce new types of antibody conjugates with dual molecular targeting. These antibody Degraducer conjugates could extend the range of therapeutic antibody conjugates available for the treatment of various cancers.

"We hope this plan to achieve a pre-clinical, proof-of-concept for antibody Degraducer conjugates will boost the efficacy, precision and safety of antibody-based therapies and lead to clinically meaningful solutions while providing improved life quality for cancer patients," expressed Cedric Sager, CEO of Debiopharm Research & Manufacturing, "We are thrilled to collaborate with Ubix Therapeutics to understand more about the potential synergies of combining their Degraducer technology with our Multilink platform."

"We’re excited to explore Antibody Degraducer Conjugates (ADeC) with Debiopharm. In particular, we’re pleased to take the opportunity to combine our Degraducer technology, having superior efficacy and high selectivity, with Debiopharm’s Multilink technology, having lots of advantages especially excellent potency through multiple loading capability. We believe that this collaboration will open up new opportunities to develop advanced cancer therapy." said BK Seo, CEO of Ubix Therapeutics.

About Multilink
Multilink is a new cleavable linker platform suited for multidrug attachment and compatible with any conjugation technology to produce ADCs with high DAR (drug-to-antibody ratio), allowing the loading of multiple payloads on an antibody for an enhanced therapeutic effect. This highly effective and well-tolerated linker platform is available for use of other specialty biotech or pharmaceutical companies to generate a proprietary, clinical-stage ADCs.

About Degraducer
Degraducer is a technology that utilizes the ubiquitin-proteasome system (UPS), an intracellular degradation system. Degraducer is a powerful inhibitor technology that enables target protein degradation and consequent therapeutic effects by placing a disease-related target protein nearby E3 ligase, which can then initiate the protein degradation system.

Pancreatic cancer is currently the third leading cause of cancer-related death in the U.S., with an overall five-year survival rate of just 10 percent. Roughly 63 percent of patients die within the first year of a pancreatic cancer diagnosis, underscoring the urgent need for new and more effective treatment options.

The new experimental treatment arm tests FibroGen’s pamrevlumab in combination with standard of care chemotherapy treatments for pancreatic cancer, Gemcitabine and Abraxane. The combination therapy is offered to patients with metastatic pancreatic cancer as either a first- or second-line treatment option, marking the first experimental treatment arm to be offered as a first-line treatment in PanCAN’s innovative Precision Promise trial. With this addition, a newly diagnosed patient enrolling in Precision Promise has the opportunity to be randomized onto an experimental therapy as their first-line treatment, and then onto another experimental therapy as their second-line treatment if they maintain eligibility when the first treatment becomes no longer effective.

"By partnering with FibroGen to bring a first-line experimental treatment arm into Precision Promise, we are expanding options for the patients enrolling in this trial," said Anne-Marie Duliege, MD, PanCAN’s Chief Medical Officer. "It is one of PanCAN’s major objectives to continue to bring innovative, experimental drugs like FibroGen’s pamrevlumab into this study in order to accelerate drug development and hopefully bring new therapies to market faster. Pancreatic cancer patients can’t afford to wait."

FibroGen’s pamrevlumab is a first-in-class antibody that inhibits the activity of connective tissue growth factor (CTGF), which, in cancer, is characterized by promotion of tumor growth. Pamrevlumab is in Phase 3 clinical development for the treatment of locally advanced unresectable pancreatic cancer (LAPC).

"We are inspired by the mission of the Pancreatic Cancer Action Network and are excited to partner with them," said Mark Eisner, M.D, M.P.H, Chief Medical Officer, FibroGen. "We share PanCAN’s goal of accelerating the development of new treatment options for pancreatic cancer patients."

PanCAN’s Precision Promise aims to revolutionize the clinical development paradigm in pancreatic cancer by enabling a faster, more efficient, and patient-centric approach to developing new treatment options and improving outcomes for pancreatic cancer patients.The novel clinical trial platform requires fewer patients to understand if a potential new therapy is working and can accelerate late stage development by up to two years. The statistical design of Precision Promise was led by renowned statistician Dr. Donald Berry (Berry Consulting), designer of the I-SPY breast cancer trials.

Precision Promise is currently open and enrolling at 15 Clinical Trial Consortium sites nationwide and PanCAN expects to add five additional sites in early 2022. In selecting the additional sites, PanCAN has set strict criteria to identify not only institutions with strong pancreatic cancer programs, but also institutions that represent new geographic areas and serve a diverse patient population in order to expand access for typically underserved communities.
