What is ASCO?
The ASCO Annual Meeting is where the most important clinical trial results in oncology are presented, often moving markets and changing practice. Oncologists, researchers, pharma and biotech teams, payers, patient advocates and investors attend.
The exhibit hall hosts pharma, diagnostics, oncology IT and service companies. Many company meetings happen in nearby hotels.

ASCO attendee profile
- Oncologists and researchers
- Pharma and biotech medical affairs, clinical and commercial teams
- Diagnostics companies
- Payers and health systems
- Investors and analysts
- Patient advocates
Most badges belong to clinicians and researchers, but the commercial value sits with the company teams who attend: pharma, biotech, diagnostics and service providers. Knowing which organisations send which functions is what makes outreach work.

Why B2B teams should care about ASCO
ASCO concentrates the oncology ecosystem. Pharma medical affairs and commercial teams, biotech executives, CROs, diagnostics companies and real-world data providers all use the meeting to connect with each other and with clinical leaders.
For vendors selling to pharma and biotech, the most valuable contacts are often not the clinicians but the company teams attending the meeting. Mapping which companies send which functions (medical affairs, clinical operations, market access) gives your outreach a clear target.
Who should attend ASCO?
Best for: CROs, data providers, lab-tools companies, health-tech vendors and agencies that sell to the organisations sending people to ASCO.
Less ideal for: anyone expecting a classic trade show. ASCO is a scientific meeting first, and most commercial conversations happen in nearby hotels.
ASCO ticket prices
| Option | Price / details |
|---|---|
| Also good to know | Fees vary by membership and category (members, non-members, industry); see the Registration & Hotels page |
| Also good to know | Non-member registration typically well over $1,000 |
| Typical cost | Roughly $1,000-2,000 for non-member/industry registrants (confirm on asco.org). |
Prices change between editions and by registration date, so treat these as a guide and check asco.org before you buy.
The ASCO app and platform
ASCO offers official mobile apps for the meeting (program, abstracts, exhibitor search).
The official app is good for finding a booth or a session. It is much less useful for prospecting: data is thin, you can’t export it, and messaging limits stop you from reaching more than a handful of people a day.
Is ASCO worth it?
| Pros | Cons |
|---|---|
| Global oncology audience | Clinical/scientific focus; compliance rules limit sales tactics |
| Major data releases attract executives and investors | Expensive for non-members |
| Strong pharma/biotech presence | Pharma interactions tightly regulated |
How to prospect at ASCO
| When | What to do |
|---|---|
| 2 months out | Decide who you want to meet: target roles, industries, company size. Then get the list of who is actually registered. |
| 1 month out | Run a short outreach sequence (three to four touches) that leads with the event and a clear meeting ask. |
| Final week | Send reminders, share your booth number or meeting spot, and prepare one-page briefs on your top accounts. |
| After the event | Send personalised follow-ups within 72 hours and tag every lead with the event name in your CRM. |
Most commercial meetings at ASCO happen in hotels around McCormick Place, not on the exhibit floor. Book a meeting room early if you plan to host prospects.
No export button in the event app? I deal with that part. Ask for the ASCO list with names, titles, companies and LinkedIn profiles in one file.
