The present invention relates to PIKfyve inhibitors, such as apilimod, and related compositions and methods for treating or preventing coronavirus infections.
1 . A method for treating or preventing a coronavirus infection in a subject in need thereof, the method comprising administering to the subject a composition comprising apilimod, or a pharmaceutically acceptable salt thereof.
2 . The method of claim 1 , further comprising administering at least one additional active agent selected from an additional PIKfyve inhibitor, a PD-L1 antagonist, a PD-L2 antagonist, and a PD-1 antagonist.
3 . The method of claim 1 , wherein the additional PIKfyve inhibitor is selected from the group consisting of APY0201, YM-201636, and pharmaceutically acceptable salts thereof.
4 . The method of claim 1 , wherein the apilimod is in the form of a free base or a dimesylate salt.
5 . The method of claim 1 , wherein the pharmaceutically acceptable salt is a monosalt selected from the group consisting of chloride, phosphate, maleate, L-tartrate, fumarate, DL lactate, and mesylate.
6 . The method of claim 1 , wherein the pharmaceutically acceptable salt is a disalt selected from the group consisting of mesylate, chloride, and bromide.
7 . The method of claim 1 , wherein the subject is a human.
8 . The method of claim 1 , further comprising administering to the subject an anti-viral agent.
9 . The method of claim 8 , wherein the anti-viral agent is one or more agents selected from the group consisting of interferon, remdesivir, azithromycin, hydroxychloroquine and chloroquine.
10 . The method of claim 8 , wherein the anti-viral agent is an interferon.
11 . The method of claim 8 , wherein the anti-viral agent is remdesivir.
12 . The method of claim 8 , wherein the anti-viral agent is azithromycin.
13 . The method of claim 8 , wherein the anti-viral agent is hydroxychloroquine.
14 . The method of claim 8 , wherein the anti-viral agent is chloroquine.
15 . The method of claim 1 , further comprising administering an anti-inflammatory agent.
16 . The method of claim 13 , wherein the anti-inflammatory agent is selected from tocilizumab and sarilumab.
17 . The method of claim 1 , wherein the subject in need is one who has symptoms of a respiratory viral infection including one or more of sore throat, nasal congestion and/or discharge, shortness of breath, difficulty breathing, and fever.
18 . The method of claim 1 wherein the coronavirus is SARS-CoV-2.
19 . The method of claim 16 , wherein the method comprises administering apilimod, or a pharmaceutically acceptable salt thereof, in combination with one or more additional therapeutic agents selected from remdesivir, azithromycin, hydroxychloroquine, chloroquine, tocilizumab and sarilumab.
20 . The method of claim 17 , wherein the apilimod is administered in a separate dosage form, or in the same dosage form, as the one or more additional therapeutic agents.
21 . A pharmaceutical pack or kit comprising, in separate containers or in a single container, a unit dose of apilimod, or a pharmaceutically acceptable salt thereof, and optionally, a unit dose of one or more of a PD-L1 antagonist, a PD-L2 antagonist, a PD-1 antagonist, and an anti-viral agent.
22 . The pharmaceutical pack or kit of claim 19 , wherein the anti-viral agent is an interferon.
23 . A pharmaceutical pack or kit comprising, in separate containers or in a single container, a unit dose of apilimod, or a pharmaceutically acceptable salt thereof, and a unit dose of one or more additional therapeutic agents selected from remdesivir, azithromycin, hydroxychloroquine, chloroquine, tocilizumab and sarilumab.
