Abstract

The present disclosures are directed to chlorinated tetralin compounds and pharmaceutical compositions.

Claims (27)

12 . The pharmaceutical composition according to claim 5 , further comprising nirogacestat, or a pharmaceutically acceptable salt thereof.

13 . The pharmaceutical composition according to claim 5 , further comprising a pharmaceutically acceptable carrier.

14 . The pharmaceutical composition according to claim 5 , wherein the pharmaceutical composition is for oral administration.

15 . The pharmaceutical composition according to claim 5 , wherein the pharmaceutical composition is a tablet.

16 . The pharmaceutical composition according to claim 3 , further comprising a gamma-secretase inhibitor selected from the group consisting of nirogacestat or a pharmaceutically acceptable salt thereof, crenigacestat or a pharmaceutically acceptable salt thereof, AL101 or a pharmaceutically acceptable salt thereof, AL102 or a pharmaceutically acceptable salt thereof, semagacestat or a pharmaceutically acceptable salt thereof, and avagacestat or a pharmaceutically acceptable salt thereof.

17 . The pharmaceutical composition according to claim 3 , further comprising nirogacestat, or a pharmaceutically acceptable salt thereof.

18 . The pharmaceutical composition according to claim 4 , further comprising a gamma-secretase inhibitor selected from the group consisting of nirogacestat or a pharmaceutically acceptable salt thereof, crenigacestat or a pharmaceutically acceptable salt thereof, AL101 or a pharmaceutically acceptable salt thereof, AL102 or a pharmaceutically acceptable salt thereof, semagacestat or a pharmaceutically acceptable salt thereof, and avagacestat or a pharmaceutically acceptable salt thereof.
