Vivo Capital, a major shareholder of TOT BIOPHARM, has partnered with the Series B investment team spanning several projects across multiple sectors. Existing shareholders and several renowned investors participated in the Series B round, fully demonstrating that investors have confidence in TOT BIOPHARM’s current achievements and future prospects. As a hi-tech company with the advantage of having built an integrated product R&D, manufacturing and marketing platform in the Chinese anti-tumor drug market, TOT BIOPHARM has been at the forefront of technological innovations and expansion into international markets for many years, and, as a result of having held steadfast to this approach, has achieved solid and steady progress. The firm has entered into strategic partnerships with several top-tier companies in the global anti-tumor sector. The completion of the Series B round will serve to accelerate the R&D of new products as well as the commercialization of existing ones, greatly improving TOT BIOPHARM’s competitive power and value.”

TOT BIOPHARM recently announced results of the Phase I clinical trial (double-blind, head-to-head pharmacokinetics and safety comparisons) of Bevacizumab biosimilar, TAB008, at ASCO 2018, demonstrating that both in pharmacokinetics and safety indicators, TAB008 shows high similarity to Avastin®. TAB008 is now in Phase III clinic trial, and, in terms of progress, TOT BIOPHARM is among the top three firms in China competing to get the drug on market. The financing will further accelerate the progress of TAB008’s Phase III study, as well as other R&D programs. The IND application for TAA013, an ADC, submitted by TOT BIOPHARM, is currently in the review process. With the higher threshold for manufacturing ADCs, the number of companies in China that can produce such drugs is quite limited. However, TOT BIOPHARM has its own manufacturing technologies and capability. The firm is in the process of ramping up production of its third-generation innovative oncolytic virus drug TVP211. Combined with its domestically leading BSL-2 certified virus manufacturing plant, TOT BIOPHARM plans to further accelerate the development program, taking a leadership position in this promising technology sector.

The construction of TOT BIOPHARM’s second-phase project – the monoclonal antibody R&D and manufacturing base was completed and put into operation in May 2018. The base, with a planned cell culture scale of up to 16,000L, was built in full compliance with international standards. Plans call for the establishment of three preparation production lines, responsible for the filling of drugs with different specifications. The facility also plans to successively launch a pre-filled preparation line, a lyophilized preparation line and a Grade OEL-5 plant for the mass production of ADC. The facility also has the flexibility to expand production capacities and adjust the layout of the production areas. Combining the existing 500L pilot plant, the facility is prepared to meet all demands for biologic drugs, from upstream R&D, pilot manufacturing, and clinical trial drugs to commercial production.
