Is ImmunoMark a general pharma conference?

No. It is a focused oncology summit with two parallel streams: Next-Gen Immuno-Oncology, and Biomarkers & Companion Diagnostics. 55–60% of the audience comes from biotech and pharma, and 45–50% is senior leadership. Sponsors use it as the oncology line in a wider London plan rather than as a replacement for large multi-therapy events.

How does it compare with a large London exhibition for a services business?

A large exhibition gives you reach and volume. ImmunoMark gives you a smaller, filtered room and pre-scheduled 20-minute 1:1 meetings with delegates you pick from the full list and profiles, sent 10 days before the event. At London 2026, sponsors held 15–25 meetings each. The fairest comparison is cost per qualified meeting, which you can test in the ROI calculator on this page.

Where are London delegates based?

The London delegate geography is 60% UK & Ireland and 40% rest of Europe, so the edition also reaches continental pharma and biotech teams.

Can my team bring clients?

Yes. Most packages include client passes alongside team passes: Gold includes 6 + 6, Platinum 8 + 8, Silver 4 + 4 and Exhibitor 2 + 2. Branding packages include 2 passes.

How many speaking slots are there for sponsors in London?

The London 2027 agenda reserves Platinum slots on Day 1 and three Gold slots per stream on Day 2 before lunch, with one Silver slot per stream after lunch on Day 2. Slots are limited, so ask the sponsorship team which remain open in your preferred stream.

London 2027 planning

Pharma conferences London: what each type of event delivers for a sponsor

The pharma conferences London hosts in a year are not one market. They are five or six different products sold under the same word, and each one buys your team a different outcome. If you are building a 2027 event plan for a pharma-services business, start by deciding which outcome you need from each line in the budget.

Below is the London calendar broken down by event type from the sponsor’s side of the table. The right mix depends on your service, your sales cycle and the buyer roles you need to reach.

Event type	Who is in the room	What a sponsor typically gets	Watch-outs
Large multi-therapy industry exhibitions	Thousands of visitors across functions, therapy areas and supplier categories	Brand presence, a high volume of badge scans, a place to launch	Your oncology buyer is one visitor among thousands; meetings depend on your own outreach, and lead quality varies widely
Partnering and investor events	BD, licensing and corporate development teams, investors, asset owners	Scheduled deal conversations through a partnering system	Built around licensing assets; service vendors often sit at the edge of the main conversation
Clinical and medical congresses	Clinicians, nurses, researchers, medical affairs	Visibility with prescribers and medical teams	Promotion to UK health professionals is tightly regulated, and the person who buys outsourced services is rarely there
Functional pharma events (marketing, market access, procurement, digital)	One function across many companies and therapy areas	A peer audience for a single discipline	Strong if you sell to that function; weak if your buyer is a scientific or programme lead
Focused therapy-area summits	A few hundred senior people from one field, mostly industry	A speaking slot, a small exhibition and pre-arranged meetings with people you chose	Smaller reach; only worth it if the therapy area matches your pipeline

Most London plans need more than one type. Large exhibitions and medical conferences London hosts give you awareness and market presence. Partnering events suit asset deals. Focused summits are where a services business tends to find the most qualified conversations per day out of the office, because the audience has been filtered for you before you arrive.

Before you sign

How to score pharma events London before they go in the budget

Commercial teams that get value from London events tend to apply the same five tests before committing, whatever the size of the event.

Name the buyer roles firstWrite down the three or four job titles that sign off on your service. A CRO might need heads of translational medicine and clinical operations; a regulatory consultancy needs CDx and regulatory leads. Then check whether the event’s audience data actually shows those roles.
Ask for the audience split, not the headcountA total attendance figure tells you little. Ask for the split by sector and seniority, and the share of the room that is industry rather than academic or clinical.
Ask how meetings are arranged“Networking opportunities” can mean a coffee queue. Ask whether meetings are pre-scheduled, who chooses the counterpart, how long each meeting runs and when you receive the delegate list.
Check what arrives before the eventLists, profiles and email reach shape your pre-event outreach. If nothing arrives until the doors open, your team is selling cold for two days.
Work out cost per qualified meetingDivide the full cost (package, travel, staff time) by the meetings you can realistically hold with named buyers. That is the number to compare across your pharma conferences London 2027 shortlist, and it usually ranks events differently from cost per visitor.

Where ImmunoMark fits

The oncology slot in your London plan

ImmunoMark Summit London is a focused therapy-area summit: the 2nd annual edition runs on 3–4 March 2027, organised by Convolign Business Consulting, with two parallel streams, Next-Gen Immuno-Oncology and Biomarkers & Companion Diagnostics.

400+target attendees for London 2027

55–60%of the audience from biotech and pharma

45–50%senior leadership: executives, directors, heads

15–25meetings per sponsor at London 2026

Delegate geography is 60% UK & Ireland and 40% rest of Europe, so a London booking also covers continental buyers without a second trip. At the 2026 edition, 300+ attendees from 100+ companies took part, 70% of them senior decision-makers, and more than 200 meetings were conducted. Companies in the room included GSK, Roche, Merck, AstraZeneca, Johnson & Johnson, Bristol Myers Squibb, Incyte and Pierre Fabre.

Among the healthcare conferences London 2027 will host, this one matters to a services vendor because the programme is built around the decisions your buyers are making. These sessions from the London 2027 agenda show which functions will be in the room:

Day 1 · Stream 2Keynote: Clinical Utility of Biomarkers (Espen Walker, Head of Global Medical Diagnostics, AstraZeneca)
Day 1 · Stream 1Panel: Scaling Immunotherapies from Discovery to Commercialisation
Day 1 · Stream 1Clinical Trial Design in Immunotherapy: Adaptive & Biomarker-Driven Models
Day 2 · Stream 2Real-World Evidence Integration into Biomarker Strategy
Day 2 · Stream 1Investment & Partnership Models in Immunotherapy
Day 2 · Stream 2Companion Diagnostics Commercialisation & Reimbursement Strategy

Speakers on the 2027 agenda come from companies including Roche, Novartis, Ipsen, Sanofi, GSK, UCB and Merck KGaA, alongside UK biotechs and university groups. For a CRO, regulatory consultancy, lab services provider or market-access agency, that is a concentrated set of oncology programme owners you would otherwise chase one by one.

Packages

Which package fits a services sponsor in London

For a team that is placing ImmunoMark alongside larger London events, the job of this line in the budget is qualified meetings plus enough visibility to be remembered. That points to the middle of the range.

We are always interested in sponsoring interesting conference, based on this years’ experience, I guess I will manage to get some budget for the next edition.

Rest of your plan

Fitting ImmunoMark around the rest of your London calendar

If your service sells across therapy areas, keep your broader presence at the large exhibitions and medical conferences London 2027 offers, and treat ImmunoMark as the oncology line. If oncology is your core market, give it more weight: a March date sits early in most budget years, so London meetings can become contracts within the year.
