A promising new drug called BAN2401 generated a lot of excitement after a clinical trial found it slowed the progression of Alzheimer’s by 30%, but recent revelations have left investors and doctors with more questions than answers, reports Bloomberg.

The bottom line: Whenever you hear about a promising new Alzheimer’s treatment, make a mental note to check back in a few months — or even a few days — to see if it’s still worth your attention.

The details: High doses of the drug, which is being developed by Biogen Inc. and Eisai Co., seemed to get results, but lower doses didn’t show any benefit. It turned out that people with a gene mutation that’s associated with Alzheimer’s were kept out of the high-dose group, at the request of regulators. That made it harder to tell whether the results for the high-dose group actually meant anything.

Facebook boycott organizers share details on their Zuckerberg meeting

Facebook is in the midst of the largest ad boycott in its history, with nearly 1,000 brands having stopped paid advertising in July because they feel Facebook hasn't done enough to remove hate speech from its namesake app and Instagram.

Axios Re:Cap spoke with the boycott's four main organizers, who met on Tuesday with CEO Mark Zuckerberg and other top Facebook executives, to learn why they organized the boycott, what they took from the meeting, and what comes next.

Civil rights leaders blasted Facebook's top executives shortly after speaking with them on Tuesday, saying that the tech giant's leaders "failed to meet the moment" and were "more interested in having a dialogue than producing outcomes."

Why it matters: The likely fallout from the meeting is that the growing boycott of Facebook's advertising platform, which has reached nearly 1000 companies in less than a month, will extend longer than previously anticipated, deepening Facebook's public relations nightmare.

House Minority Whip Steve Scalise’s PAC is inviting lobbyists to attend a four-day “Summer Meeting” at Disney World's Polynesian Village in Florida, all but daring donors to swallow their concern about coronavirus and contribute $10,000 to his leadership PAC.

Why it matters: Scalise appears to be the first House lawmakers to host an in-person destination fundraiser since the severity of pandemic became clear. The invite for the “Summer Meeting” for the Scalise Leadership Fund, obtained by Axios, makes no mention of COVID-19.
