Abstract

Disclosed are formulations comprising brincidofovir. The formulations can be intravenous formulations. The formulations can be used in cases where a subject experiences gastrointestinal issues in response to oral administration of brincidofovir. The formulations can also be used in cases where oral administration of drug is not possible due to underlying conditions or concern around inadequate oral absorption.

Claims (20)

1 . An aqueous pharmaceutical composition, comprising:

brincidofovir at a concentration of about 10 mg/mL;

mannitol at a concentration from about 2.5% (w/v) to about 9% (w/v);

L-arginine at a concentration from about 100 mM to about 200 mM, and water;

wherein the pH of the composition is about 8.0, and wherein the composition shows less than 0.05% drug related impurities when stored at 5 (+3° C.) for 1 month.

2 . The pharmaceutical composition of claim 1 , wherein the mannitol is present at a concentration of about 2.5% (w/v).

3 . The pharmaceutical composition of claim 1 , wherein the mannitol is present at a concentration of about 5% (w/v).

4 . The pharmaceutical composition of claim 1 , wherein the L-arginine is present at a concentration of about 100 mM.

5 . The pharmaceutical composition of claim 1 , wherein the pH is adjusted using HCl and/or NaOH.

6 . The pharmaceutical composition of claim 1 , comprising:

brincidofovir at a concentration of about 10.0 mg/mL,

mannitol at a concentration from about 25 mg/mL to about 50 mg/mL;

L-arginine at a concentration of about 17.4 mg/mL; and

water;

wherein the pH of the composition is about 8.0.

7 . The pharmaceutical composition of claim 1 , wherein the composition is free of visible particulates when stored at 5 (±3° C.) for 6 months.

8 . The pharmaceutical composition of claim 1 , wherein the composition is free of visible particulates when stored at 25 (±2° C.) for 6 months.

9 . The pharmaceutical composition of claim 1 , wherein the composition is free of visible particulates when stored at 25 (±2° C.) for 12 months.

10 . The pharmaceutical composition of claim 1 , wherein the composition was not lyophilized prior to storage.

11 . The pharmaceutical composition of claim 1 , wherein the composition is suitable for intravenous administration.
