Thermosome Gets Orphan Status on Sarcoma Drug
FDA has granted Thermosome an orphan drug designation for THE001 and its use in treating soft tissue sarcomas (STS). “In its decision, the FDA recognized that Thermosome's innovative doxorubicin-encapsulating thermosensitive liposomes may be clinically superior to currently approved non-liposomal forms of doxorubicin due to its potential for increased efficacy,” the company says. The designation is based on preclinical and early clinical data from a Phase 1 study, it adds.
THE001 uses a unique formulation of doxorubicin combined with deep regional radiofrequency hyperthermia to target doxorubicin-sensitive tumors like soft tissue sarcomas, according to the company. It delivers up to 15-fold higher local drug concentration in the tumor to overcome drug resistance.
Currently, Thermosome says the drug is being investigated in a phase 1 clinical trial, with the primary end point of maximum tolerated dose, and secondary end points include adverse events (AEs), serious AEs, laboratory abnormalities, electrocardiogram abnormalities, echocardiogram abnormalities, renal toxicity, and pharmacokinetics.
