Beyond Anti-Body Drug Conjugates – A New Enhance Approach 

September 13, 2023

 

Elucida Oncology is founded on the CDOT technology, which utilizes ultra-small silica spheroids functionalized with targeting molecules and drug payloads through cleavable linkers. This technology enables precise tumor targeting, deep penetration, and renal clearance. 

Lead Program (ELU001): ELU001 is their primary program, a folate receptor alpha targeted CDC. It exhibits promise in a wide range of tumor types, including those with varying levels of antigen expression, making it highly versatile. 

Advantages Over ADCs: 

  • Potency: CDOT drug conjugates (CDCs) are more potent than traditional ADCs due to higher drug payload per particle. 

  • Tumor Penetration: CDCs penetrate tumors effectively, including brain metastases, which is challenging for ADCs. 

  • Safety Profile: CDCs have a differentiated safety profile with no off-target toxicities common in ADCs. 

  • Biodistribution: CDCs exhibit a favorable biodistribution pattern, minimizing contact with healthy tissues. 

  • Frequency of Administration: CDCs may require less frequent administration due to their prolonged tumor retention. 

  • Clinical Progress: Elucida Oncology has made significant clinical progress, advancing into dose expansion cohorts in ovarian and endometrial cancer. They have also explored effectiveness in liquid tumors and demonstrated promising results in various preclinical and clinical models, including brain metastasis and pediatric AML. 

Market Potential

Elucida Oncology's technology has the potential to address a substantial portion of the ovarian cancer market, including patients with varying levels of folate receptor alpha expression. Their CDCs offer a differentiated therapeutic approach with improved efficacy and safety, potentially capturing a significant market share and creating substantial value in the oncology space. 

Development of ELU001 Safety Profile

The company initially observed promising results in laboratory bio-distribution studies, which showed no accumulation of ELU001 in healthy tissues. This was followed by PK and bio-distribution studies in humans, reaffirming the absence of accumulation in healthy tissues. During the dose-ranging work involving over 35 patients, the company closely monitored for these specific toxicities and found no cause for concern. They plan to continue treating expansion cohorts while collecting safety data, aiming for both efficacy and a differentiated safety profile. 

Overcoming Challenges in ELU001 Development

One significant challenge has been achieving progress with a small, talented team in a nimble manner. Staying focused and disciplined has been crucial. Despite the desire to explore various avenues, the company aims to demonstrate the potential of its technology fully. Elucida Oncology has successfully advanced ELU001 to patient expansion cohorts in a relatively short time by maintaining focus, determination, and teamwork 

Strategic Collaborations and Partnerships 

Elucida Oncology has collaborated with a top-tier pharmaceutical company that recognized the potential of their technology. They are working on different drug molecules and mechanisms to enhance cancer treatment. The company is also open to various transaction types and collaborations to develop ELU-001 further. Additionally, they have partnerships with companies utilizing different molecules for targeting cancer cells in combination with their particles. 

Global Expansion Goals and Entry into China Market

Elucida is open to regional transactions, including those in China and Asia. The company's primary focus is on advancing ELU-001 to demonstrate the capabilities of its platform fully. They believe that the technology's toxicity advantage will extend to other targets and payloads, making it well-positioned for strategic deals and value creation.
