Andy and JC get the lowdown from Robert Pacifici, CSO of CHDI Foundation, on the latest in Huntington's treatments from the recent 20th CHDI Therapeutics Conference in Palm Springs, California. Robert has spearheaded efforts at CHDI for the past 22 years, driving forward preclinical drug discovery programs and corralling efforts to develop bioassays, clinical biomarkers, patient-staging systems, clinical and regulatory consortia to galvanize industry efforts in this devastating and fatal neurodegenerative disease. Just four years after the field suffered several reverses for ASO therapies in late-stage clinical development, there is renewed optimism that a new set of disease-modifying therapies are within reach.

William Pao, CEO of Revelio Therapeutics, and former Chief Development Officer for Pfizer/Head of Roche pRED, sits down with JC and Andy to talk about his new book: 'Breakthrough: The quest for life-changing medicines'. By charting the ups and downs of eight different drugs and the challenges faced by those shepherding them through the complex drug approval process, the book provides a fascinating peek into the hidden world of pharmaceutical discovery and the tireless work of the dedicated R&D professionals who develop life-changing medicines.    

INGREDIENTS: 

6-8 mint leaves 

Bar spoon of water 

Ice cubes 

1 Oz elderflower liqueur (e.g., St. Germain) 

4 Oz Sparkling wine (e.g. Prosecco)

Sebastian Giwa, co-founder of the Organ Preservation Alliance and the Biostasis Research Institute and serial entrepreneur, talks to JC and Andy about the promise of organ storage research in transplantation. Seb obtained a PhD in Economics at the Stockholm School of Economics and was named a Baker Scholar at Harvard and worked at Bridgewater Associates, Bain and Goldman Sachs. Since spending time at Singularity University/NASA's Global Solutions Program and working with the Obama White House, he has worked tirelessly to galvanize the new field of whole organ preservation seeking to massively expand the availability of donor organs for the hundreds of thousands of patients awaiting transplants. 

Seb's ventures in preservation: Sylvatica Biotech (named for the wood frog that can survive freezing and developing supercooling technology to extend organ life), Ossium Health (bone marrow banking from deceased organ donors for patients with sickle cell anemia, leukemia, and lymphoma), and GaiaLife (human ovary vitrification for girls with cancer who have not yet reached puberty). 

Seb's preferred digestivo: Flaming Sambuca ("Sambuca, ghiaccio e mosche"; roughly translated: “Sambuca, ice and flies.”)

You will need:
1  2-1/2 oz shot glass
3 coffee beans
1.5 fluid Oz (44 mL) of sambuca
1 Butane lighter

Directions: 
Place the beans at the bottom of the glass. Pour in the Sambuca. Use the lighter (do not use matches containing sulfur or phosphorus; preferably long-reach lighter to avoid setting yourself alight!) to light the sambuca, then wait until the flame is low/blue and cover the shot glass with your hand to extinguish it.

https://bit.ly/3YxRltJ. Andrew Lo, Charles E. & Susan T. Harris Professor of Finance and director of the Laboratory for Financial Engineering at the MIT Sloan School of Management, gives JC and Andy the skinny on his progress in finding new commercialization models for rare diseases. He also reveals plans on implementing his debt securitization megafund model, first described over a decade ago. Finally, he gives us some tips on how to prepare a delicious refreshing sparkling sake:

1) Mio sparkling sake 
1 bottle Mio sake
1 freezer

DIRECTIONS:
From Andrew: "Store bottle of Mio at 58ºF (the recommended temperature of typical wine cellar). Move bottle to the freezer section of your refrigerator for about two hours before you're ready to consume it. The time is approximate, and depends on how cold your freezer is, so you may need to play around with this key parameter. After two hours, remove the bottle from the freezer; it should still be completely liquid inside (if it's partially frozen, you've kept it in too long and need to thaw it before opening). 

Assuming that the sake is completely liquid, twist open the bottle and QUICKLY POUR OUT A SERVING INTO YOUR GLASS. The reason you have to pour quickly is that the sake is sparkling, which means the carbonation creates pressure in the bottle. Once this pressure is released, the liquid starts to foam and the foam will freeze, clogging the bottle and making it impossible to pour out any liquid. By pouring it quickly, the foam forms in the class, yielding the desired frozen treat. The remaining liquid in the bottle is blocked by the frozen foam in the neck, but this will melt while you enjoy the first pour, and should be ready to be poured out in just a few minutes (though the foam won't be quite as thick in the second glass).

This works best with Mio's individual 375ml bottles. It can be done with full 750ml bottles but it's hard to pour multiple glasses fast enough before the foam freezes in the neck (you have to line up your glasses and pour quickly in a straight line)."
