Biotecnol Limited and Chiome Bioscience Inc of Japan have entered into an asset purchase agreement.

On December 3, 2018 Under this agreement, Biotecnol reported that divested from it’s immuno-oncology pipeline and respective technologies (including Tb535H, and Trisoma (Press release, Biotecnol, DEC 3, 2018, View Source [SID1234570279]). Chiome will continue research and clinical development for Tb535H. In addition, Chiome will continue generating new immune-oncology products using Biotecnol’s Trisoma technology. Financial details were not disclosed.

About Tb535H

Tb535H is a T-cell engager, trispecific antibody, directed against the 5T4/WAIF1 tumour antigen, a protein found on many different solid tumours and is thought to contribute to the spread of cancer cells. Tb535H recruits the patient’s T-cells –killer cells of the immune-system – and directs them to attack tumours. This highly targeted approach uses the patient’s own immune system to fight cancer. The WAIF1 antigen was discovered by scientists at the Cancer Research UK Manchester Institute. It could be a valuable target in many different cancer types, but the initial focus in this trial will be to treat cancers with high unmet-need. This includes thoracic cancers such as mesothelioma, small-cell lung carcinoma (SCLC) and non-small cell lung cancer (NSCLC), for which survival remains very low, and renal cell carcinoma.

About Trisoma technology

The Trisoma technology enables the generation of multi-specific antibody products. This unique technology overcomes the key shortcomings of conventional mono- as well as of currently developed bi-specific antibody formats. With the Trisoma technology, Biotecnol can engineer and assemble recombinant antibodies in a rational manner in order to design a chosen mechanism of action to address the killing of a specific tumour type.
