Cancer therapies can eliminate specific tumors based on their genetic content. However, some cancer cells survive. How do they do it? Part of the answer lies in extrachromosomal DNA (ecDNA), an ace up the tumors’ sleeve to adapt and evade attack. Three simultaneous studies in the journal Nature lay all the cards on the table, revealing ecDNAs’ content, their origin, their inheritance, their influence in cancer, and a way to combat them.

Radiopharmaceutical biotech and contract development and organization firm Duchembio Co. Ltd. filed a securities report to South Korea’s Financial Services Commission Nov. 11, kickstarting the IPO process to list on the Korea Exchange.

University of Auckland senior research fellow Jeff Smaill first visited China in 2012 as part of a team of 15 scientists from the Maurice Wilkins Center, one of New Zealand’s centers of excellence, to meet with scientists at the Guangzhou Institute of Medicine and Health to find partners to collaborate on drug development projects. The scientists started collaborating that year, and the first project is already in phase I trials in China. It was a joint discovery and development partnership from the beginning, he said.

Alteogen Inc. scored another deal for its human recombinant enzyme, ALT-B4, on Nov. 8, reeling in Daiichi Sankyo Co. Ltd. in a potential $300 million deal including $20 million up front and up to $280 million in milestone payments, along with royalties based on net sales.

Abbisko Therapeutics Co. Ltd.’s colony-stimulating factor 1 receptor inhibitor, pimicotinib, met both primary and secondary endpoints in the phase III Maneuver global study evaluating pimicotinib for treatment of tenosynovial giant cell tumor.

Gain-of-function mutations and overexpression of the EZH2 gene lead to H3K27Me3 accumulation, which in turn initiates tumorigenesis and tumor progression, thus making it a promising target for therapy.
