The Paris Life Sciences team advises Nanobiotix (Euronext: NANO –– NASDAQ: NBTX), on a non-dilutive royalty financing agreement with HealthCare Royalty (HCRx) for up to $71 million, in exchange of a portion of royalties from the sales of the product JNJ-1900 (NBTXR3), a novel, potentially first-in-class oncology product composed of functionalized hafnium oxide nanoparticles that is administered via one-time intratumoral injection and activated by radiotherapy, and which has been the subject of an exclusive license agreement with Janssen Pharmaceutica NV, a Johnson & Johnson company.

According to the royalty financing agreement, Nanobiotix will receive an upfront payment of $50 million and is eligible to receive an additional $21 million payment one year post closing, subject to reaching certain conditions.

As a counterpart, and subject to the receipt of $71 million, HCRx shall be entitled to receive a repayment from a defined portion of royalties and a portion of certain regulatory and commercial milestone payments.
