Accelerated Approval for Lilly Sarcoma Drug
FDA has granted accelerated approval to Eli Lilly for its soft tissue sarcoma (STS) drug Lartruvo (olaratumab) and its use with chemotherapy drug doxorubicin in those who cannot be cured with radiation or surgery. Lartruvo is a platelet-derived growth factor (PDGF) receptor-alpha blocking antibody. “When stimulated, PDGF receptors cause tumor growth. Lartruvo works by blocking these receptors, which may help slow or stop tumor growth,” an agency release says.
Approval was based on data from a randomized clinical trial involving 133 patients with more than 25 different subtypes of metastatic STS. “Patients in this trial who received Lartruvo with doxorubicin had a statistically significant improvement in overall survival: the median survival was 26.5 months compared to 14.7 months for patients who received doxorubicin alone,” FDA says. “Patients who received Lartruvo with doxorubicin had a median progression-free survival of 8.2 months compared to 4.4 months for patients who received doxorubicin alone. Tumor shrinkage was 18.2% for patients who received Lartruvo with doxorubicin and 7.5% for those who received doxorubicin alone.”
