Ladies and Gentlemen:

Pursuant to Rule 461 under the Securities Act of 1933, as amended, we attach the requests of our client, PPD, Inc., and of the underwriters that effectiveness of the above-referenced Registration Statement be accelerated to 4:00 p.m., Eastern Time, on September 16, 2020, or as soon as practicable thereafter. We ask, however, that the Securities and Exchange Commission staff not accelerate such effectiveness until we speak with you on that date.

Very truly yours,
