Pinnacle Biologics Inc. has completed its portfolio of photodynamic therapy (PDT) treatment components with the acquisition of Diomed’s PDT 630 laser and fiber optic diffuser Optiguide. Financial terms were not disclosed.

The privately-held biopharmaceutical company’s acquisitions are the only FDA-approved devices for use in PDT with Photofrin (porfimer sodium) for injection.

Photofrin — acquired by the company in March 2011 — is a two-stage process requiring administration of both drug and light. When injected, it is attracted to certain tissues, especially cancer cells, and is FDA-approved for the treatment of nonsmall-cell lung and esophageal cancer.
