A year after reporting side effects “not seen before in ocular genetherapy” in a clinical trial, the biotech is eliminating 38% of its workforce to save cash while it runs a new study.
The company is working with trial researchers to investigate further. Pfizer said the patient, a young boy who was treated earlier last year, had died suddenly.
How and When to Incorporate PK Design into Your GeneTherapy Development Plan. Genetherapy, which was in its infancy around 30 years ago, is now becoming a more prominent treatment method in many therapeutic areas, from personalized therapy to mass vaccinations against COVID-19. GeneTherapy Definition.
The European Commission (EC) has granted conditional marketing authorisation (CMA) for BioMarin Pharmaceutical ’s genetherapy, Roctavian (valoctocogene roxaparvovec), to treat adults with severe haemophilia A (congenital Factor VIII deficiency).

The deal will see Polyplus join the German life science group’s portfolio allowing the latter to leverage expertise in transfection reagents and plasmid DNA for genetherapy. Polyplus, based in Strasbourg, France, produces key components in the production of viral vectors used in cell and genetherapies.
Beacon Therapeutics has kickstarted its entry into the genetherapy field with a $120m Series A financing. Amongst it was AGTC’s lead clinical candidate, AFTC-501, an adeno-associated virus (AAV) genetherapy for XLRP. The asset, now transferred to Beacon Therapeutics, is currently in Phase II clinical trials.
Preliminary results from a Phase 1 study show Sangamo’s treatment to be safe and suggest it is working as intended, leading the biotech to move into the trial’s next phase.
On 10 March, the National Health Service Blood and Transplant (NHSBT) opened a new Clinical Biotechnology Centre (CBC) with the aim of improving the UK’s ability to develop and manufacture cell and genetherapies. In the past, researchers have often had to seek help from outside the UK, thus delaying clinical trials and patient access.
If things go as per plan, in a few months, the US Food and Drug Administration (FDA) will deliberate on the first-of-its-kind CRISPR-based genetherapy for sickle cell disease (SCD) and transfusion-dependent beta thalassemia. We also explore how AI is being used to design digital twins for clinical trials.
Amplo Biotechnology has received a fast track phase I/II STTR grant from the NIH-NIAMS [National Institutes of Health’s National Institute of Arthritis and Musculoskeletal and Skin Diseases] for its genetherapy AMP-201. The company will receive substantial funding to advance AAV-ColQ genetherapy.
The spotlight was placed on many up-and-coming pharmacotherapies for retinal diseases, one of which was AbbVie’s/Regenxbio’s genetherapy RGX-314. Clinical trial results in DR patients have shown that 47% of eyes treated with RGX-314 have experienced diabetic retinopathy severity score (DRSS) improvements of two or more steps.
Safety concerns, including the recent death of a patient in an early study, led the FDA to place a hold on the therapy and Pfizer to redesign its Phase 3 trial.
For many decades, investigators have been working on innovative therapeutic modalities known as cell and genetherapies, which use modified versions of the body’s own cellular and genetic material to treat and potentially cure these diseases. A new frontier in cancer research.
