Curing ovarian cancer through autoantibody-based therapy

Introduction

Ovarian cancer (OC) is a malignant tumor with poor prognosis and limited treatment options, responsible for 4.4% of cancer-related mortality in women. There is an urgent need for innovative therapeutic approaches for OC.

Antibody Drug Conjugates (ADCs)

Antibody drug conjugates (ADCs) represent one of the most promising therapeutic approaches, but their efficacy has been hindered by the identification of suitable tumor-associated antigens. For example, ADCs targeting MUC16, the best diagnostic marker for OC, have thus far failed in clinical trials due to shedding of MUC16 from the tumor.

Breakthrough Discovery

Our breakthrough lies in the identification and characterization of a MUC16-specific autoantibody clone – 2B5, which specifically targets the non-shed and highly conserved epitope of MUC16 that stays associated with the tumor. This consequently dramatically increases the efficacy of the cytotoxic payload delivery to the tumor and overcomes limitations of similar ADCs that have failed in the past.

Potential Impact

By directly and selectively targeting MUC16 on OC while sparing healthy tissues, our ADC has the potential to revolutionize OC therapy by finally offering a precise and effective ADC cancer treatment.

Project Objectives

Thus, for this PoC, we aim to demonstrate the effectiveness of our 2B5-based ADC as a leading candidate for OC therapy in humans.

Development Goals

In order to increase its therapeutic and commercial potential, the 2B5-based ADC will be developed further to:

1. Identify the most suitable payload.
2. Validate its tumor-killing efficacy in pre-clinical animal models, which will be developed in the framework of this project.

Timeline and Outcomes

By the end of this PoC, we aim to be ready to develop our 2B5-ADC to human grade towards phase 1 clinical trials.

Business Strategy

Simultaneously, we will define the innovation's commercial feasibility and business model and will validate the business opportunities and go-to-market strategies with relevant stakeholders.

Intellectual Property

Furthermore, we have already initiated the process of patenting our innovation and aim to finalize it during the PoC.
