So, what happened during January 2025?
In world news:
January 1st – Liechtenstein became the 37th country to legalize same-sex marriage.
January 1st – Russia halted the transportation of its gas supplies across Ukraine following the expiration of a five-year transit deal (it is a very strange war in many ways…).
January 16th – Blue Origin successfully launched its heavy-lift launch vehicle, New Glenn, into orbit on its first attempt.
January 22nd – The Fraternal Order of Police (the largest police union in the USA with over 355,000 members) – which endorsed President Trump in September 2024 – said they were “deeply discouraged by the recent pardons and commutations granted by both the Biden and Trump Administrations to individuals convicted of killing or assaulting law enforcement officers” (Source).
January 24 – Storm Éowyn hit Ireland and the United Kingdom. Record high wind speeds of 183 km/h (114 mph) are recorded in Ireland, while over a million homes are left without power.
In the world of Parkinson’s research, a great deal of new research and news was reported:
In January 2025, there were 1,382 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (1,382 for all of 2025 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).
The top 6 pieces of Parkinson’s news
1. Inbrain Pharma Phase 1 results:
The results of the Inbrain Pharma‘s Phase 1/2 randomized-controlled, open-label trial of intracerebroventricular administration of anaerobic dopamine (A-dopamine) in 12 people with Parkinson’s; Safe & well tolerated; Dyskinesia & bradykinesia were reduced (Click here to read more about this).

2. Tetanus–diphtheria vaccinations:
Using national health providers data in Israel, a retrospective case–control study finds tetanus–diphtheria vaccination significantly reduced the occurrence of Parkinson’s; Adjusted OR of 0.17 (95% CI [0.04, 0.70]) for PD Dx within 5 years post-vax (Click here to read more about this).

3. Deep brain stimulation is disease modifying?:
Using Parkinson’s Progression Markers Initiative (PPMI) data, researchers found that circulating lymphocytes progressively decrease in Parkinson’s & can predict future motor symptom progression. Interestingly, they also found that deep brain stimulation causes a shift from the pro-inflam CD4+ Th17 cells to anti-inflam CD4+ Treg cells (Click here to read more about this).

4. Encouraging Phase 2 results from Alterity Therapeutics:
ATH 434 (formerly PBT 434) is an orally bioavailable, small molecule, inhibitor of α-synuclein aggregation, being developed by Alterity Therapeutics. In January, the company announced encouraging topline results from their 12 month-long “ATH434-201” randomized, double-blind, placebo-controlled Phase 2 clinical trial in 77 patients with early-stage multiple system atrophy. This study found that ATH434 was safe and well tolerated, reduced iron accumulation, and provided a 48% slowing of clinical progression (Click here to read the press release and click here to see the results presentation).
5. Ur-ine for some interesting kidney research:
Researchers report α-synuclein deposits in the kidneys of 10/11 patients with Parkinson’s & 17/20 patients with chronic kidney diseases (CKD). Notably, in 7 cases of the CKD cases had synuclein inclusions in their spinal cord, midbrain & amygdala. The investigators followed up by exploring renal failure in mice & found it promotes deposition of α-synuclein in the kidney & also in the brains (after intravenous injections of α-Synuclein). Intrarenal injection of α-Synuclein fibrils also lead to α-Synclein pathology in the kidney & brain. Curiously, deletion of α-synuclein from blood cells attenuated the progression of α-synuclein pathology; Mice receiving Snca−/− bone marrow had less pathology & more dopaminergic terminals density in the striatum than in mice that received wild-type bone marrow (Click here to read more about this).
6. Blue Rock Therapeutics goes Phase 3!:
Blue Rock Therapeutics plans to initiate a Phase 3 clinical trial for bemdaneprocel (its investigational cell therapy) for Parkinson’s; With Regenerative Medicine Advanced Therapy (RMAT) designation, the “exPDite-2” study is expected to begin in the first half of 2025 (Click here to read more about this).
