Dren Bio Inc. has closed on a $60 million series A to push its two lead programs through early clinical development. The company’s DR-01 is an antibody-based therapy for treating rare leukemias, lymphomas and specific phenotypes of autoimmune disorders. The company said it is initially targeting neglected hematology-oncology indications.

Even though the appetite for biopharma IPOs this year has been voracious with no signs of a slowdown anytime soon, companies also have a potentially faster route to the public market using special purpose acquisition companies (SPAC) that raise money through an IPO in order to take a company public through an acquisition.

Rayzebio Inc. raised $45 million in a series A round to build a platform company focused on developing targeted radiopharmaceuticals for solid tumor indications.
