The lineup

Founders, CEOs and investors from across cell & gene therapy - plus the Onyx Live team on the mic. The lineup is preliminary and still firming up.

Speakers & moderators

November, London. For 16 years, biotech leaders have gathered for the Jefferies global healthcare conference and the satellite events of London Life Sciences Week, supported by the Office for Life Sciences and the Mayor of London. Cell and Gene Leaders London is something new - an invitation-led gathering in a private room, 34 floors up, where the key players meet before the main conference begins.

Sessions run alongside complimentary food and drink from breakfast through to the afternoon reception, with The Shard as the backdrop - room to meet, compare notes and do business from morning until early evening.
