Piramal Pharma Solutions, a contract development and manufacturing organization (CDMO), said it is providing Bolt Biotherapeutics with the supply of both the BDC-1001 ISAC drug substance and the drug product for Bolt’s ongoing Phase 1/2 clinical study in cancer patients.
 
The Piramal Pharma Solutions (PPS) team is applying its integrated drug development model to Bolt’s BDC-1001 for the treatment of patients with HER2-expressed solid tumors. The program encompasses formulation development and ISAC development and manufacture at PPS’ Grangemouth, UK site. The drug substance is then processed into lyophilized, sterile fill-finish vials at PPS’s Lexington, KY, site. According to the company, this seamless integration across two PPS sites, which shortens delivery timelines and expedites distribution to clinic, is an example of PPS’ patient-centric philosophy.
 
“Bolt’s technology platform has demonstrated significant, positive data in preclinical models, including the development of immunological memory against tumors, and is now in a human clinical trial,” said Peter DeYoung, chief executive officer, Piramal Pharma Solutions. “The manufacturing of ISACs utilizes essentially the same process as antibody drug conjugate (ADC) manufacturing, enabling us to capitalize on our deep expertise in this space. Our ability to produce these novel ISACs and package them for clinical trials in one efficient, integrated process compresses the timeline of the development of Bolt’s drug. We remain committed to our patient-centric approach and are proud to partner with an industry-leader like Bolt to help reduce the burden of disease on patients.”
 
Nathan Ihle, vice president CMC and quality, Bolt Biotherapeutics, said, “Bolt is a leader in ISAC technology, and our partnership with Piramal Pharma Solutions is important to bring our technology to the clinic. Piramal’s experience in the manufacture of commercial ADCs provides Bolt with a reliable partner for the development of BDC-1001.”
 
The first cycle of drug substance to drug product manufacturing has been successfully completed through PPS’ integrated program. Additional cycles are in progress, as are further developments that will benefit future indications and new clinical programs.
