Duke-NUS Bio-Entrepreneur Series – Spinning out a cancer immunotherapy startup – The Story of PairX Bio: Post-Event Write-Up
In the latter half of 2020, BCS partnered with Duke-NUS to host the Duke-NUS Bio-Entrepreneur Series. This series consisted of two talks that featured two different start-ups: the newly minced cancer immunotherapy startup PairX Bio and a Singapore-based biotech company, Enleofen.
The first webinar of the series titled “Spinning out a cancer immunotherapy startup – The story of PairX Bio” was moderated by Dr. Natasha Ng, President of BCS and featured Dr. Raymond Lee, Research Fellow at Duke-NUS; Mr. XQ Lin, Managing Partner at Esco Ventures X and Ms. Cheryl McCaffery, Director, CTeD Duke-NUS. Together they shared how PairX Bio was spun out from a humble lab-based setting with an aim of developing novel cancer immunotherapies against shared tumor-associated antigens.
The webinar started with Raymond discussing the challenges of spinning out a new technology. A basic understanding of what a biotech is; dealing with the unknowns such as IP, business venture model; the need to show capability (that the technology will work) and to use it to address fundamental questions were some of the things that were brought forth. In their case, there was also a huge unmet need to identify new cancer antigens, especially shared tumor antigens that are derived from aberrantly spliced proteins. PairX platform, built upon the mRNA splicing process, therefore focuses on discovering novel antigens that are shared across subsets of different cancer types and validating them in different settings.
XQ emphasized that apart from science, it is important to address bottlenecks early-on such as whether the platform technology has the potential to generate assets that could advance to clinical trials. Translational potential of the idea should also be discussed at the early stages of a project and the need to build a working prototype should take precedence over everything else. Additionally, it is imperative to engage with experts with diverse skill sets and foster collaborations, not only locally but globally as well. Cheryl addressed the importance of protecting the technology, even if it comes at the expense of publications. She emphasized that unless a patent is filed, the scientific work should not appear in any public platform irrespective of the time it takes to file a patent.
Together they shared the importance of bringing life-saving therapeutics to patients and discussed the next steps in commercializing the technology such as expanding the data sets to include different cancer types, getting regulatory approvals and approaching global investors to seek funding. They shared the importance of engagement with stakeholders early-on, talking to the right people at the right time and finding the right platforms to generate interest about the technology or product. It is also worthwhile to understand who the consumers are, how will the technology benefit them and how will it reap commercial benefits in return.
