CPX-351 is a liposomal formulation consisting daunorubicin and cytarabine with fixed ratio for treatment of AML.
TLC-ART 101 is a lipid nanoparticle formulation consisting lopinavir, ritonavir and tenofovir with fixed ratio for treatment of HIV/AIDS.
Drug ratios in these formulations molar ratios of daunorubicin:cytarabine and lopinavir:ritonavir:tenoforvir, respectively.
The steps indicate simplified key procedures in manufacturing of CPX-351 and TLC-ART 101.
