Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.

why aren't all 9 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable

Andy Tran: Gene Editing Enables Curative Single-Dose Treatments
“Of course, this is certainly a big paradigm shift and very exciting as these technologies have given us the power to precisely target And eliminate the origin of disease, as well as be very curative with just a single dose of the drug.”

Assertion Supported
Tran: 24 gene therapies slated for Phase 3 trials in 2019
“There are about two dozen more gene therapies that are slated to just have phase three trials in this year alone.”

Assertion Supported
Andy Tran: Gene therapy startups drove major biotech exits
“In fact, taking a look at the past several years, some of the largest biotech exits have been from companies developing these gene therapies.”
Andy Tran Oct 5, 2019 ▶ 2:47 CRISPR 2.0 and the Future of Gene Therapies
Assertion Supported
Tran: CRISPR cut gene editing engineering timelines from months to days
“Compared to old tools, engineering was cut down from a few months to a matter of weeks or days.”
Andy Tran Oct 5, 2019 ▶ 4:56 CRISPR 2.0 and the Future of Gene Therapies
Assertion Supported
Tran: Alternative Cas nucleases offer advantages in size and precision over Cas9
“Some Cas nucleases are much smaller, come from less immunogenic strains, are more precise, or have new mechanisms altogether.”
Andy Tran Oct 5, 2019 ▶ 6:08 CRISPR 2.0 and the Future of Gene Therapies
Assertion Supported
Tran: CRISPR tools can directly target and edit RNA bases
“We can even now directly target and edit RNA bases, opening up the entire field of transcriptomic editing.”

Assertion Supported
Tran: FDA and CBER introduced accelerated approval guidance for gene therapies
“This past year we've seen FDA and CBER leaders drum up plans to make a big push on assessing new cell and gene therapies, as well as introducing new guidance on accelerated approvals for these new areas of product development.”

Assertion Contradicted
Andy Tran: AAVs are the only clinically approved gene therapy vectors
“To jump in, probably the natural place to start is on the AV side, as these adeno-associated viruses are the only clinically approved vector so far for gene therapy.”

Assertion Supported
Tran: Current genome editing tools face immunogenicity and off-target issues
“Once it is inside the cell, many of our current protein-based genome editing nucleases are still plagued by off-target effects, low efficiency, and side effects from the immunogenicity of the protein itself.”
