With one biopharma set to price its IPO this week, three others – neurology-focused Aptinyx Inc., stem cell gene therapy firm Avrobio Inc. and specialty pharma Xeris Pharmaceuticals Inc. – have set terms for their anticipated offerings, putting the sector on track to match last year's IPO activity, at least in terms of number of offerings. In terms of money raised, however, the first half of 2018 looks like it might top the amount raised in global IPOs priced in the first half of 2017.
