Applicant discloses methods and compositions for treating a patient suffering from amyotrophic lateral sclerosis (ALS) comprising administration of a heteroaryl ketone fused azadecalin compound. In embodiments, the heteroaryl ketone fused azadecalin compound is dazucorilant: (R)-(1-(4-fluorophenyl)-6-((4-(trifluoromethyl)phenyl) sulfonyl)-4, 4a, 5,6,7,8-hexahydro-1-H-pyrazolo[3,4-g]isoquinolin-4a-yl) (pyridin-2-yl)methanone, having the chemical structure illustrated as

##STR00001##

Suitable doses include daily administration of 150 milligrams and 300 milligrams of dazucorilant. Suitable doses include daily administration of dazucorilant with food, or with water, or with food and water. Daily administration of dazucorilant is effective to increase dazucorilant exposure up to about 2-fold when continued for seven days or more. Administration of such a heteroaryl ketone fused azadecalin compound may comprise oral administration, enteral administration, or other administration. Pharmaceutical compositions comprising dazucorilant are useful in the treatment of patients suffering from ALS. Suitable pharmaceutical compositions comprising dazucorilant include, e.g., pharmaceutical compositions for oral administration and pharmaceutical compositions for enteral administration.

A compound, as represented by formula I, as a TLR7 agonist, a method for preparing the compound, and the use of the compound in treating diseases mediated by the TLR7 agonist are provided. Studies on the activity of a human-derived receptor, a TLR7 agonist, show that compounds have a strong agonistic effect on the human-derived receptor, TLR7, and can be used as a foreground compound for treating diseases mediated by the TLR7 agonist.
