Zuranolone Improves Depressive Symptoms Within 14 Days
https://www.psychcongress.com/article/zuranolone-improves-depressive-symptoms-within-14-days
October 15, 2020:
Zuranolone, an investigational neuroactive steroid, improved depressive symptoms in a majority of patients within a 14-day treatment course, Sage Therapeutics reported.
Topline results from the ongoing phase 3 open-label SHORELINE Study also demonstrate zuranolone was well-tolerated in patients taking 30 mg, and among patients treated with the 50 mg dose after the study protocol was changed in May to include it, according to a press release from Sage.
This data from the SHORELINE Study show that medically-oriented, as needed treatment for depression has the potential to be a compelling option for many patients diagnosed with MDD, said Sage chief executive officer Jeff Jonas, MD.
Approximately 70% of patients who participated in the study only needed one or two treatment courses, a total of two to four weeks of treatment with zuranolone 30 mg, which we believe will be the minimally effective dose, if our development efforts are successful.
Zuranolone (SAGE-217) is a once-daily oral two-week therapy being developed as a treatment for major depressive disorder (MDD) and postpartum depression (PPD). It has similar pharmacology as the intravenous drug brexanolone (Zulresso), approved by the US Food & Drug Administration (FDA) in 2019 for the treatment of postpartum depression.
A neuroactive steroid GABAA receptor positive allosteric modulator, it has been granted Breakthrough Therapy Designation by the FDA. Sage plans to report more data from the 30 mg dose group in the first half of 2021.
Exploring the Role of GABA in Psychiatric Treatment
The yearlong longitudinal SHORELINE study is evaluating the safety, tolerability, and need for repeat dosing with zuranolone in adults aged 18 to 75 years who have MDD, defined by a baseline total score of ≥ 20 on the Hamilton Depression Rating Scale (HAMD-17).
The initial 725 participants had an average baseline score of 25.3 ± 4.1. After the first 14-day course of once-nightly zuranolone 30 mg, patients had a mean change from baseline of -14.9 ± 7.1 (n=640); 458 (71.6%) patients showed a response and 255 (39.8%) achieved remission, defined as a HAMD-17 score of ≤ 7.
Some 304 (42%) of the participants were on other antidepressant therapy, which was continued, and 421 (58%) were not. There were no meaningful differences in efficacy outcomes between the two groups, Sage reported.
Repeat Treatments
Need for additional treatment courses was assessed based on a Patient Health Questionnaire (PHQ-9) score of ≥10 and HAMD-17 score of ≥20. There were at least 56 days between each 14-day course.
From the initial cohort, 494 patients who had responded continued after the first treatment course and 274 (55.5%) of them were retreated with zuranolone at least once; 132 (26.7%) used a total of 2 courses, 66 (13.4%) used 3 courses, 51 (10.3%) used 4 courses, and 27 (5.5%) used 5 courses. At the time of data analysis, patients who responded to the initial course used a mean of 1.9 treatments per year.
Efficacy and safety outcomes were similar to those from the first course, and there was no correlation between the number of zuranolone retreatments and the use of other antidepressants, the company reported.
Among patients who received 1 or more retreatments, overall adverse event rates were 151 (53.7%) in the second course, 56 (38.1%) in the third, and 28 (35.9%) for the fourth course.
An Increased Dosage
In May, participants being retreated began receiving zuranolone 50 mg, and a new cohort of patients started treatment at that dose.
The 52 patients in the new cohort had a mean HAMD-17 baseline score of 25.1 ± 3.1. At day 15, the mean change was -15.9 ± 6.6 (slightly higher than in the initial cohort). A total of 39 (75.0%) patients responded to a 14-day treatment course and 25 (48.1%) achieved remission, also both higher than among the 30 mg cohort.
In the 76 (38%) new participants with safety data available, somnolence, dizziness, sedation, headache, and tremor were more frequent than in the 30 mg group, but were similar in severity. Among the 48 participants who has previously received 30 mg zuranolone, a higher number of and more intense adverse events were reported while taking 50 mg.

Wikipedia:
--
Zuranolone (INN;[1] developmental code names SAGE-217, S-812217) is an investigational medication which is under development by SAGE Therapeutics for the treatment of depressive disorders and a variety of other indications.[2][3] It is a synthetic, orally active, inhibitory pregnane neurosteroid, and acts as a positive allosteric modulator of the GABAA receptor.[2][3][4] The drug was developed as an improvement of allopregnanolone (brexanolone) with high oral bioavailability and a biological half-life suitable for once-daily administration.[3] As of October 2019, zuranolone is in phase III clinical trials for major depressive disorder, postpartum depression, and insomnia and is in phase II clinical studies for bipolar depression, essential tremor, and Parkinson's disease.[2] It is also in the preclinical stage of development for dyskinesias.[2]

Thanks for posting. Hopefully there will be a new era of effective and tolerable drugs in a few years. Im not falling for any me too drugs anymore. I have endured enough crazy detrimental reactions during experiments with them.

If the drugs are not fundamentally different, results will probably be equally unpredictable.

Very interesting.
Nice to have another alternative to SSRIs. Apparently SSRIs do affect the levels of allopregnanolone (a positive modulator of GABA-a receptors), but they also have a lot of collateral effects. Having something based on an existing brain chemical is interesting.
CBD is a positive allosteric modulator of GABA-A receptors and has (seemingly) helped me stay more stable.

Linkadge does CBD interact with medication and what brand and strength do you buy?

Sounds rather good, but a placebo cohort for comparison would be interesting...
