Elevating the standard of care in neuroblastoma

Safer therapies start with tumour specificity.

Our Mission

OGD2 Pharma is developing a next generation of biotherapies designed to substantially improve tolerability and efficacy in cancer treatment.

Our approach targets O-acetylated GD2 (OAcGD2), a tumour-restricted antigen enabling more selective therapeutic strategies. We are advancing a focused pipeline in high-risk neuroblastoma and other solid tumour cancers with high unmet medical needs.

The Unmet Need

Effective treatment should not come at the expense of quality of life – especially in paediatric care.

Neuroblastoma is an aggressive paediatric cancer arising from immature nerve cells. Current immunotherapies have significantly improved survival outcomes but remain difficult to tolerate. Many children experience severe pain and neurological side effects, which can limit dosing and increase overall treatment burden.

Our Approach

OAcGD2: A breakthrough in tumour targeting

What is OAcGD2?

O-acetylated GD2 (OAcGD2) is a tumour-restricted variant of the clinically validated GD2 target. Unlike GD2, it is not detected in healthy peripheral nerve tissue but remains strongly expressed on tumour cells.

Our innovation

We have developed a proprietary antibody that selectively targets OAcGD2, with no cross-reactivity to GD2. This enables precise tumour targeting while sparing healthy tissues and reducing treatment burden for patients.

OAcGD2 vs GD2-targeting antibody therapies

OAcGD2-targeting (our approach):

GD2-targeting (conventional approach)

Elevating the standard of care in neuroblastoma

Eliminates the pain burden

Improves tolerability

Enhances the survival potential

Promises improved efficacy

Redefines the economics of care

Enables outpatient treatment

Our Pipeline

Leading the OAcGD2-targeted drug class

Our proprietary antibody platform specifically targets OAcGD2, a tumour-restricted antigen. The lead programme focuses on high-risk neuroblastoma, where the need for safer, more tolerable treatments is most urgent. Building on this foundation, the platform is being expanded into additional OAcGD2 expressing tumours and alternative therapeutic formats.

Partnership Opportunities

Join us to advance a next generation of cancer therapies

With our lead OGD201 programme now in the IND-enabling stage, OGD2 Pharma is seeking strategic partners and co-investors to accelerate our clinical trajectory and ensure access for children with high-risk neuroblastoma.

Our proprietary OAcGD2-targeting platform additionally offers unique opportunities in other modalities, including antibody drug conjugates (ADCs), multispecific antibody formats, and chimeric antigen receptor (CAR) based cell therapies.

About us

OGD2 Pharma, a venture of Remora Biotech, is a privately held biotechnology company headquartered in Nantes (France). The company is a carve-out of ATLAB Pharma, a previous Remora Biotech venture, which was acquired by Telix Pharmaceuticals in 2014.

Our vision is to lead the OAcGD2-targeting drug class, as the sole company developing proprietary antibodies against this novel antigen, and to establish a new generation of biotherapies for neuroblastoma and other OAcGD2-expressing cancers.

Thank you for your message. We have received your request and appreciate your interest in our services. Our team will review it and get back to you as soon as possible with a response.

We look forward to speaking with you soon.
