CCM International Scientific Meeting


17th Anniversary Angioma Alliance

CCM Scientific Meeting

November 11 & 12, 2021

The CCM Scientific Meeting is a venue for international stakeholders to assemble, share, and discuss the latest CCM research data. Angioma Alliance hosts this annual meeting to facilitate scientific progress and collaborations.

Our virtual meeting will take place on November 11 and 12.  As we did last year, we will be asking plenary speakers to pre-record their presentations so that you may view them during the 2 weeks before the meeting. The meeting itself will consist of discussion panels and Q&A. You must register for the meeting to view presentations.

New this year, we will also host two virtual poster sessions on these days. All told, there will be approximately 3 hours of meeting each day, with timing optimized to allow for global attendance. Please scroll to the bottom of this page for local times.


Who may attend?

Attendance at the annual CCM Scientific Meeting is open for those with active CCM research programs (principal investigators, postdoctoral fellows, and students), CCM clinical practice, CCM drug development, and CCM advocacy (e.g., Angioma Alliance board members). Officials from the National Institutes of Health and Food and Drug Administration are also encouraged to attend. Upon registration, attendees will complete an eligibility questionnaire. Final attendance eligibility determinations are subject to decision by the Organizing Committee. To request registration information, please contact Connie Lee at

Attendance is limited to the above-described eligibility criteria to protect the confidentiality of unpublished data. Therefore, patients, care providers, and other family members (even those with medical or scientific training) are not allowed to attend scientific sessions.

More Information

We send announcements, including registration links, via email to our current scientific mailing list. If you have not been receiving regular correspondence from us about poster sessions or this meeting, please write to be added to the distribution list.

In 2020, we hosted a virtual meeting where we shared unpublished data, engaged in lively discussions, facilitated hypothesis generation, and drove research for a cure for CCM.  View 2020 Agenda
