Activities, Events, or Meetings in Conjunction With CROI (Affiliated and Proximate Activities)


PLEASE NOTE: An Affiliated Activity is any activity, event, or meeting, including virtual meetings and conference calls, held at any time from 3 days before (Thursday, March 5) through 2 days after (Friday, March 13) the 2020 Conference on Retroviruses and Opportunistic Infections (CROI) and targeted toward or includes any REGISTRANTS of CROI.

The goal of CROI is to promote meaningful and high-level interchange of scientific ideas to find better ways to prevent and treat HIV and AIDS and to one day develop a cure. In support of that goal, organizations (eg, commercial companies, their agents, not-for-profit groups, and government agencies) that wish to hold meetings targeted to or involving any CROI attendee(s) and taking place around the time of the conference and within its vicinity must complete the Affiliated Activity application, be approved, and comply with the guidelines below.

In order to provide opportunities for different groups and attendees within non-blackout of CROI times to attend affiliated and proximate meetings, each organization may hold no more than one (1) affiliated meeting on each of the CROI program days (excludes the days prior or days after program days).

To be approved, Affiliated and Proximate Activities must:

  • Support and be consistent with the scientific nature of CROI
  • Be nonpromotional and noncommercial (commercial companies are be allowed to hold affiliated and proximate activities as long as the activities themselves are nonpromotional and noncommercial)
  • Not conflict with or detract from the official CROI scientific program
  • Be approved in advance
  • Be held within a hotel that is part of the CROI hotel block or request and receive prior written approval for an alternate location

An administrative fee is required for approved Affiliated and Proximate Activities:

  • A $250 application fee will be assessed upon approval of Affiliated and Proximate Activities for commercial companies
  • A $50 application fee will be assessed upon approval of Affiliated and Proximate Activities for not-for-profit organizations, and government and academic programs

In general, commercial company–supported activities are permitted only during the pre or post days of CROI 2020. Commercial companies are defined as any profit entity (including but not limited to pharmaceutical companies, medical communication firms, and diagnostic companies) or its agents (including but not limited to public relations, publishing, or advertising firms). If you have any questions about whether you are considered a commercial entity, please email before submitting your Affiliated and Proximate Activity application. No promotional advisory board meetings, fishbowls, or social or leisure events are allowed (see below). Acceptable activities are:

  • Scientific Advisory Board Meetings
  • Scientific Investigator Meetings

Company employee-only activities, such as company employee dinners or meetings that do not include any nonemployee CROI registrants, may be permitted during the nonblackout times on conference days, pending application review.

In general, activities sponsored and supported by not-for-profit or governmental organizations that are permitted during breakfast, lunch, and in the evenings on days of the scientific program (no such events can be held during the blackout times of CROI 2020) include:

  • Scientific Board Meetings
  • Committee Meetings
  • Executive Meetings
  • Specific Study (Investigator) Meetings

In some circumstances, social events that are organized by not-for-profit or government organizations may be approved during the nonblockout times of CROI.

In general, the following are not permitted pre/post/during CROI:

  • Scientific, educational, speaker-driven symposia or lectures not sponsored by CROI
  • Investor and/or investment-focused activities
  • Commercial company–hosted social events (eg, cocktail receptions, dinner cruises, sporting events, hosted noncasual organized dinner events of more than 10 people)
  • Exhibits (by commercial and noncommercial companies)
  • Distribution of any promotional material (eg, fliers, room drops)
