ODEFSEY (emtricitabine, rilpivirine, and tenofovir alafenamide) is a fixed-dose combination tablet containing emtricitabine (FTC), rilpivirine (RPV), and tenofovir alafenamide (TAF) for oral administration. FTC, a synthetic nucleoside analog of cytidine, is an HIV-1 nucleoside analog reverse transcriptase inhibitor (HIV-1 NRTI). RPV is an HIV-1 non-nucleoside reverse transcriptase inhibitor (NNRTI). TAF, an HIV-1 NRTI, is converted in vivo to tenofovir, an acyclic nucleoside phosphonate (nucleotide) analog of adenosine 5′-monophosphate. Each tablet contains 200 mg of FTC, 25 mg of RPV (equivalent to 27.5 of rilpivirine hydrochloride) and 25 mg of TAF (equivalent to 28 mg of tenofovir alafenamide fumarate) and the following inactive ingredients: croscarmellose sodium, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polysorbate 20, and povidone. The tablets are film-coated with a coating material containing iron oxide black, polyethylene glycol, polyvinyl alcohol, talc, and titanium dioxide. Emtricitabine: The chemical name of FTC is 4-amino-5-fluoro-1-(2 R -hydroxymethyl-1,3-oxathiolan-5 S -yl)-(1 H )-pyrimidin-2-one. FTC is the (-)enantiomer of a thio analog of cytidine, which differs from other cytidine analogs in that it has a fluorine in the 5 position. FTC has a molecular formula of C 8 H 10 FN 3 O 3 S and a molecular weight of 247.24 and has the following structural formula: FTC is a white to off-white powder with a solubility of approximately 112 mg per mL in water at 25 °C. Rilpivirine: The chemical name of rilpivirine hydrochloride drug substance is 4-[[4-[[4-[(E)-2-cyanoethenyl]-2,6-dimethylphenyl]amino]-2-pyrimidinyl]amino]benzonitrile monohydrochloride. Its molecular formula is C 22 H 18 N 6 ∙ HCl and its molecular weight is 402.88. Rilpivirine hydrochloride has the following structural formula: Rilpivirine hydrochloride is a white to almost white powder. Rilpivirine hydrochloride is practically insoluble in water over a wide pH range. Tenofovir Alafenamide: The chemical name of tenofovir alafenamide fumarate drug substance is L-alanine, N -[( S )-[[(1 R )-2-(6-amino-9 H -purin-9-yl)-1-methylethoxy]methyl]phenoxyphosphinyl]-, 1-methylethyl ester, (2 E )-2-butenedioate (2:1). Tenofovir alafenamide fumarate has an empirical formula of C 21 H 29 O 5 N 6 P∙½(C 4 H 4 O 4 ) and a formula weight of 534.50 and has the following structural formula: Tenofovir alafenamide fumarate is a white to off-white or tan powder with a solubility of 4.7 mg per mL in water at 20 °C.
