“…Also very recent reports of the benefits of terazosin and related compounds (Alpha-1-adrenergic blocking agents), used for the urinary symptoms of prostate disease and/or for hypertension - slows or prevents neuro-degeneration. A prospective study [TZ-PD Ph II 13 ppl trial for safety & tolerability - NCT03905811 ] confirmed benefits in a small number of patients. But the important research came from the Parkinson's Progression Markers Initiative database [ PPMI ], showing that this class of drug reduced hospital or clinic visits, disease complications, as well as specific scores for walking/gait/coordination measures, for and neuropsychiatric scores. The diagnosis of new Parkinson's disease was reduced by 38%.”

2019 Sept Monthly Research Review – September, (SoPD)
“Chinese and US researchers published data suggesting that prostatic hyperplasia and hypertension drug, terazosin could be repurposed for Parkinson’s. Multiple PD models & human medical database evidence were presented in their report. They found that Terazosin activates phosphoglycerate kinase 1 (PGK1), one of the first enzymes in ATP production (the energy that cells run on). Treatment with terazosin rescued multiple neurotoxin & genetic models of Parkinson’s, and human dopamine neurons from LRRK2-G2019S patients that were grown in cell culture. MarketScan medical records database analysis found 2880 Parkinson’s patients with PD taking Terazosin (or similar) “had fewer PD-related diagnoses” than 15,409 individuals with PD + no Terazosin. PD-free individuals on Terazosin had reduced frequency of PD (0.62; P < 0.0001). A Phase II clinical trial for Terazosin in Parkinson’s is already being organised. It is a double blind, placebo controlled,12 weeks treatment in 20 people with PD (1:1 randomisation). Safety is the primary outcome, and it will be reporting in early 2020 (Click here to read the report, click here to read more about the clinical trial, click here to read the press release, click here for a good overview of this research, and click here to read an SoPD post on this topic).”

"There is a great deal of Parkinson’s preclinical research that is focused on clinically available drugs (for a good example see the recent SoPD post on the prostate drug Terazosin – click here to read that post). We don’t need to re-invent the wheel and come up with new formulations of old drugs to test whether a theory might work. That process requires years of research and longer clinical safety testing. We can use a clinically available drug, which will give us a proof of concept as to whether the hypothesized biology is important/relevant to Parkinson’s."

"In addition, there were a host of new clinical trial initiated, many of which are exploring entirely new experimental therapies. These include . . .
Terazosin – This prostatic hyperplasia and hypertension drug was found to enhance Phosphoglycerate kinase 1 (Pgk1) activation & a phase II trial was immediately initiated (Click here to read a SoPD post on this topic)."
2020 Jan The Road Ahead (SoPD)
"Another mitochondrial-focused clinical trial initiated in 2019 was a drug-repurposing study involving the prostatic hyperplasia and hypertension drug, Terazosin. Researchers published data suggesting that terazosin could rescue models of Parkinson’s by boosting energy production in mitochondria. A 12 week Phase II clinical trial for Terazosin in Parkinson’s was set up to assess safety of the drug in peope with Parkinson’s, and it is scheduled to finish in 2020 (Click here to read about the clinical trial and click here to read an SoPD post on this topic)."

"New clinical study registered: Researchers will be exploring the effect of an adrenergic receptor blocker (Terazosin) on cardiac & striatal transporter uptake in pre-motor & symptomatic Parkinson’s (Click here to read more about this)."

Considering the print type that Simon Stott is allocating to this drug, I'm inclined to think it worth watching going forward.
