Pipeline Expansion. In May 2026, we entered into a new option agreement with Hangzhou DAC for access to CPT113, their core linker-payload technology, for use in up to five additional ADC programs. Per the terms of the option agreement, we will select targets and source antibodies, while retaining global rights and full program control for the new ADC programs. We anticipate submitting IND applications for multiple new programs over the next 12-24 months.
Current report
In addition, in June 2026, we entered into a global collaboration with Biocytogen to develop bispecific antibody-drug conjugates ("BsADC"). Biocytogen will provide access to up to five bispecific antibodies using its proprietary RenLite® platform, and we will evaluate these in combination with our ADC linker-payload platform technologies. We then have the option to advance any resulting BsADC candidates as part of our pipeline.

These in-licensed assets originated through the collaborative efforts of WuXi Biologics, a leading global contract research, development and manufacturing organization (“CRDMO”), and Hangzhou DAC Biotechnology (“Hangzhou DAC”), a global leader in ADC innovation, where Hangzhou DAC’s CPT113 linker-payload has been conjugated to novel antibodies developed by WuXi Biologics against three tumor targets: Protein Tyrosine Kinase 7 (“PTK7”), Mucin 16 (“MUC16”) and Seizure-related Protein 6 (“SEZ6”). We believe the resulting ADCs will be able to target cancers expressing these respective tumor markers precisely and deliver the potent, cytotoxic TOP1 inhibitor at the site of cancer. Each of these ADCs have demonstrated tumor cell binding, tumor cell line cytotoxicity, andin vivo antitumor activity in preclinical models mimicking tumor progression. We refer to these in-licensed ADC assets as the "ADC Therapies" herein.

For the periods presented and through the FYARRO Divestiture (as defined below), our lead drug product was FYARRO®(sirolimus protein-bound particles for injectable suspension (albumin-bound); nab-sirolimus). Nab-sirolimus is a potent inhibitor of the mTOR biological pathway with demonstrated anti-cancer activity in advanced malignant perivascular epithelioid cell tumor (“PEComa”), a rare cancer. We exclusively licensed FYARRO, previously called ABI-009, nab-sirolimus, from Abraxis BioScience, LLC, a wholly owned subsidiary of Celgene Corporation, which is a wholly owned subsidiary of Bristol-Myers Squibb Company (“BMS”). We refer to the development, production and commercial sale of FYARRO herein as the “FYARRO Business”.
