Third and last session of #psychedelics @NIH ๐Ÿ‡บ๐Ÿ‡ฒ workshop starting now, looking at how to optimize clinical trials design and how to get these treatments approved ๐Ÿงต
Starting with Ido @hartogsohn ๐Ÿ‡ฎ๐Ÿ‡ฑ on psychedelic set and setting theory
Important Q โ“

Do we have an (excessively) costly and complicated drug regulation apparatus?
Now my friend @DrSureshMuthu, lead author of one of the most important papers of 2021 tandfonline.com/doi/full/10.10โ€ฆ, on how to improve clinical trial designs ๐Ÿค“
The unblinding problem has been drawn โœ๏ธ
High unblinding in psychedelic trials
A paradox? ๐Ÿ™ƒ
Possible treatment designs
Many biases. What was controlled in the end?
Great work and excellent talk @DrSureshMuthu ๐Ÿ‡ณ๐Ÿ‡ฟ
Next @appelbap on Ethical issues and challenges for research and clinical use
Sexual abuse issues โš ๏ธ
Steering the future through ethics
Next is Javier Muniz from @US_FDA ๐Ÿ‡บ๐Ÿ‡ฒ
Unique challenges
Psychotherapy and labeling
Important recommendations to reduce bias ๐Ÿง
Last panel now facing some hard questions:

How do we regulate this in safe and beneficial ways?

What else is needed and how will it unfold?

Unblinding was the major issue in @Lykos_PBC MDMA efficacy review by @US_FDA's PDAC

In 2011 I started a post-doc with ayahuasca and figured out the obvious: double-blinding wouldn't work. In 2014 I discussed this at @Imperial_PRG without success

We need better epistemology ๐Ÿงต๐Ÿ‘‡ Image
It is striking how the field of evidence-based medicine (EBM) continuously endorses blinding as the most reliable control for post-randomization biases, when in fact there's much evidence to systemic failures and epistemic bias, as I presented at PS23 Image
Less than 10% of biomedical RCTs measure and report unblinding, and many unblinded trials were published without disclosing this issue, including in top journals and for already approved medications. Image

7even years ago @PNASNews published results of our neuroimaging exploration with #LSD, bravely led daily by @RCarhartHarris and a young trio @LeorRoseman myself and @MendelKaelen in the early days of @Imperial_PRG, exploring unknown frontiers despite huge prejudice all around... Image
One day, with LSD inside my blood, I saw an unforgetable infinitude of things, including the MRI transform into a massive surgical robot laser-cutting thin slices of my brain which flew at light speed into the computer screen in the nearby room...
And I asked myself "Can they see my thoughts on screen"?

That seemed a silly idea and I laughed alone in the noisy cold room (relieved as other visions were of sensuous aesthetics, luckily never asked about ๐Ÿ™ƒ)...

This equinox the @IPCC_CH released the updated edition of our best "manual for spaceship earth" ๐Ÿ˜‰, nicely summarized by Prof. @KHayhoe here:

Should we build connections between our existential #climatecrisis and psychedelics?
๐Ÿงต๐Ÿ‘‡ Image
In a nutshell:
"a batata ๐Ÿฅ” ta assando ๐Ÿ”ฅ"
(the potato is roasting), as people say in Brazil ๐Ÿ‡ง๐Ÿ‡ท when facing complicated problems Image
But the GOOD NEWS ๐Ÿคž is that YES we have many #AvailableSolutions ๐Ÿ’ซ

And as I highlighted in green in this image, indigenous lands and knowledge are fundamental for implementing some key solutions. Image

This is likely the single most important paper in psychedelic science ๐Ÿ’ซ since "the LSD lid" (2017) and the "dmt-sigma 1" (2009) publications

What connects them is literally mind-blowing ๐Ÿคฏ
Absolutely congrats to @DEOlsonLab and all collaborators ๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘ science.org/doi/10.1126/scโ€ฆ
Here is the 2017 LSD "lid" paper by @zenbrainest et al, also superb cell.com/cell/fulltext/โ€ฆ

This is a good landmark to claim psychedelic science finally achieved maturity
Basic research is evolving rapidly and public funding ๐Ÿ’ฐis what is needed to transform the field
Clinical trials suggest transdiagnostic safety and efficacy

Today is the second day of psychedelics @NIH ๐Ÿ‡บ๐Ÿ‡ฒ with a critical issue to be tackled:

What is a #controlled study with psychedelics?

How to do it?

Why is it important?
Starting now with Michael Bogenschutz from @nyuniversity discussing what was left in the background yesterday: subjective effects
Mixed correlation results between MEQ subjective ratings and therapeutic outcomes for alcohol abuse ๐Ÿค”
