Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Olaratumab is a recombinant human IgG1 monoclonal antibody that binds to platelet-derived growth factor receptor alpha (PDGFRα), blocking PDGF-AA, -BB, and -CC binding and receptor activation, thereby inhibiting tumor growth.
Uvadex, when combined with UVA light, intercalates into DNA and upon UVA activation forms covalent cross-links with pyrimidine bases, thereby inhibiting DNA synthesis and inducing apoptosis in activated T-cells.
10 mg/kg IV every 2 weeks until disease progression or unacceptable toxicity.
200 mcg/mL solution administered via intravenous injection 0.017 mL/kg (3.4 mcg/kg) 30 minutes prior to each photopheresis treatment, given on two consecutive days every 2–4 weeks.

Terminal elimination half-life is approximately 11 days (range 4–20 days), supporting a 3-week dosing interval when combined with doxorubicin.
Terminal elimination half-life is approximately 12 hours (range 8-20 hours) following intravenous administration; clinically, this supports daily dosing schedules.
Olaratumab is cleared primarily via proteolytic catabolism; no specific renal or biliary excretion studies have been conducted. In patients, only trace amounts are excreted in urine (<1% of dose).
Primarily renal excretion of unchanged drug (approximately 70% within 24 hours) and metabolites; minor fecal elimination (<10%).
