For the first time, doctors will have a drug to combat acute graft-versus-host disease — a dangerous side effect of stem cell transplants in which donor cells attack the recipient — before it occurs.
The FDA has approved Bristol Myers Squibb’s Orencia to prevent aGVHD in combination with certain immunosuppressants, the company announced on Wednesday. Adults and kids two years and older can take the drug if they’re undergoing hematopoietic stem cell transplantation from an unrelated recipient.
‘Acute graft versus host disease can affect different parts of the body and become a serious post-transplant complication,’ said Richard Pazdur, director of the FDA’s Oncology Center of Excellence. ‘By potentially preventing the disease, more patients may successfully undergo bone marrow or stem cell transplantation with fewer complications.’
Orencia was initially approved in 2005 for the treatment of adult rheumatoid arthritis and has since been expanded to treat polyarticular juvenile idiopathic arthritis and adult psoriatic arthritis.
Its latest approval was based on key clinical data, plus real-world evidence. In one study, dubbed GVHD-1, patients who received Orencia saw a 90% overall survival rate compared to 84% in the placebo group. For moderate-severe aGVHD-free survival, patients who received Orencia saw a 50% rate compared to 32% for patients who received a placebo. However, severe aGVHD-survival was not significantly improved in patients who received Orencia compared to placebo.
GVHD-2, which made use of real world data, showed a 98% overall survival rate in patients who took Orencia on top of standard of care immunosuppressants, compared to 75% for patients who received standard immunosuppression alone six months after transplantation. — Nicole DeFeudis
Japan’s Sosei Heptares inks deal with Twist — to focus on antibody discovery
Earlier this year, Japanese biotech Sosei Heptares suffered a setback when pharma giant AbbVie backed out of a deal on Sosei’s G protein-coupled receptors. But as of this morning, Sosei has signed another deal — this time with Twist Biosciences on antibody discovery against GPCR targets identified by Sosei.
Sosei Heptares will bring its isolated GPCR target proteins to the collaboration, while Twist will leverage its in-house antibody libraries and bioinformatics as part of the deal, according to a joint statement from the two biotechs.
Sosei Heptares will have exclusive and full global rights to develop and commercialize any antibody leads identified and directed to the GPCR targets in the deal. Twist will be eligible for an upfront payment, R&D costs and future payments based on predefined development milestones. The financial terms of the deal remain undisclosed.
Twist co-founder and CEO Emily Leproust expressed optimism for the deal, and said in a statement ‘We are pleased to partner with Sosei Heptares.’ — Paul Schloesser
Oxford AI software imaging firm Brainomix closes Series B worth $21.2M
British AI-software precision medicine company Brainomix has closed a Series B round, adding $21.2 million to its coffers.
The funds will pay for Brainomix’s expansion into new markets and new indications such as lung fibrosis and cancer, the company said in a statement.
The financing was co-led by existing investors Boehringer Ingelheim Venture Fund and Parkwalk Advisors, alongside new investor Tencent Holdings and participation from Oxford University Innovation Fund.
The company built an AI platform that automates imaging biomarker analysis — which is designed to improve diagnosis and treatment decisions. The company has been focused on imaging strokes via AI, but now Brainomix can move beyond stroke and develop novel imaging biomarkers for better treatment of lung fibrosis and cancer.
‘We welcome Tencent as a highly experienced new investor and thank Parkwalk and BIVF, as well as OUIF, for their continuing support,’ said Brainomix co-founder and CEO Michalis Papadakis in a prepared statement. — Paul Schloesser
Cerevel enlists Herophilus for organoid-based schizophrenia deal
Cerevel Therapeutics has found a new partner to develop neuropsychiatry drugs as organoid chatter heats up in investor circles.
The biotech is teaming up with Herophilus, the companies announced Thursday, aiming to marry Cerevel’s drug R&D capabilities with the latter’s AI-enabled deep phenotyping. Herophilus’ platform uses ‘patient-derived brain organoids and neuroimmune genetically engineered brain organoids,’ in the hopes of making animal models obsolete for schizophrenia treatment.
‘Research and development for neuroscience diseases is difficult, and schizophrenia in particular can be incredibly challenging to address,’ Cerevel CSO John Renger said in a statement. ‘The science and cutting-edge approach that this collaboration brings to the table has the potential to reveal core mechanisms of schizophrenia and disease-modifying approaches to treat it.’
Thursday’s deal comes a week after Stanford spinout NextVivo earned a seed round to flesh out its organoid technology. Whereas Cerevel and Herophilus are researching schizophrenia, NextVivo is going after immune system disorders. — Max Gelman
