Paragraph 00488, (2022/02/05)
This invention relates to a 19-nor C3,3-disubstituted C21-pyrazolyl steroid of formula (I) and pharmaceutical compositions thereof. Also disclosed herein are methods of making the pharmaceutical compositions of the 19-nor C3,3-disubstituted C21-pyrazolyl steroid of formula (I) and methods of using the 19-nor C3,3-disubstituted C21-pyrazolyl steroid of formula (I) or crystalline solid forms, pharmaceutically acceptable salts, and pharmaceutically acceptable compositions thereof.

Certain classes of neuroactive steroids (NASs) are positive allosteric modulators (PAM) of synaptic and extrasynaptic GABAA receptors. Herein, we report new SAR insights in a series of 5β-nor-19-pregnan-20-one analogues bearing substituted pyrazoles and triazoles at C-21, culminating in the discovery of 3α-hydroxy-3β-methyl-21-(4-cyano-1H-pyrazol-1′-yl)-19-nor-5β-pregnan-20-one (SAGE-217, 3), a potent GABAA receptor modulator at both synaptic and extrasynaptic receptor subtypes, with excellent oral DMPK properties. Compound 3 has completed a phase 1 single ascending dose (SAD) and multiple ascending dose (MAD) clinical trial and is currently being studied in parallel phase 2 clinical trials for the treatment of postpartum depression (PPD), major depressive disorder (MDD), and essential tremor (ET).
