Which CROs Are Most Active in European Haematology Phase III Trials, and Where Is Support Needed Most?

21 June 2026

Across 164 European haematology Phase III trials authorized through CTIS from 2024–2026, 96 trials used at least one CTIS-listed CRO or outsourced support provider, equal to 58.5% of the cohort. ICON Clinical Research was the most active named provider, appearing in 27/164 trials, followed by IQVIA in 20/164 and Parexel in 16/164. CRO demand was strongest in operationally complex EU submissions: 50/52 trials with 7+ countries used CRO support, compared with only 6/48 one-country trials.

Provider count is trial-level: one provider counted once per trial, even if multiple duties were listed.
Interpretation

The ranking is led by full-service CROs, but the top group also includes specialist vendors for data capture, randomisation, and logistics. For CTIS-facing EU haematology programs, outsourcing is therefore not only trial management; it is a bundled operating model spanning country activation, site operations, data systems, and supply controls.

At what operational scale are CROs needed most?

Country footprint was the strongest CRO trigger. CRO support appeared in 80/88 trials with 4+ European countries, equal to 90.9%, and in 50/52 trials with 7+ countries, equal to 96.2%. Site count was a weaker but still relevant signal: 43/64 trials with 26+ sites used CRO support, equal to 67.2%.

Sites
≤10 sites: 21/50 CRO-supported (42.0%)
11–25 sites: 30/48 (62.5%)
26–50 sites: 25/37 (67.6%)
51+ sites: 18/27 (66.7%)
Participants
≤100 participants: 61/87 CRO-supported (70.1%)
101–250 participants: 21/39 (53.8%)
251–500 participants: 6/21 (28.6%)
501+ participants: 8/17 (47.1%)
Interpretation

In European haematology Phase III trials, CRO need is more strongly tied to EU country complexity than to participant volume. The 7+ country threshold is the clearest outsourcing trigger, because it combines CTIS Part II country coordination, local site start-up, language-specific consent materials, and multi-country operational governance.

Which haematology diseases show the highest CRO need?

Among disease groups with at least five trials, paroxysmal nocturnal hemoglobinuria had the highest CRO-support rate at 7/7 trials, equal to 100.0%. Hemophilia followed at 9/11 trials, or 81.8%, and thrombosis/coagulation studies reached 11/15 trials, or 73.3%.

Hemophilia91181.8%
Thrombosis / coagulation111573.3%

Multiple myeloma111957.9%
Myelodysplastic syndrome5955.6%
Sickle cell disease71353.8%
Lymphoma72231.8%
Disease groups are normalized from CTIS trial-disease labels and counted at trial level.
Interpretation

The strongest CRO need appears in rare or operationally specialized haematology segments rather than only in the largest oncology-haematology malignancy categories. PNH and hemophilia combine small participant pools with multi-country site networks, making CRO support valuable for feasibility, patient access, CTIS country coordination, and specialist site activation.

What functions are outsourced most often?

The most common outsourced functions were central lab/biomarker testing in 94/164 trials, equal to 57.3%, and full-service CRO or clinical operations in 93/164 trials, equal to 56.7%. Digital data capture, electronic clinical outcome assessment (eCOA), and electronic trial master file (eTMF) support appeared in 67/164 trials, equal to 40.9%.

Trial-level frequency of outsourced functions
Central lab / biomarker testing94/164 · 57.3%
Full-service CRO / clinical operations93/164 · 56.7%
Digital data capture / eCOA / eTMF67/164 · 40.9%
IMP supply / storage / logistics61/164 · 37.2%
RTSM / randomisation / IP allocation58/164 · 35.4%
Safety / ECG / imaging / adjudication52/164 · 31.7%
Patient recruitment / support / reimbursement49/164 · 29.9%
IMP means investigational medicinal product; RTSM means randomisation and trial supply management.
Interpretation

The outsourced stack is heavily operational and infrastructure-led. In haematology Phase III, sponsors most often need partners for laboratory and biomarker workflows, EU site operations, digital data capture, RTSM, IMP logistics, safety review, imaging, and patient-support services rather than only generic monitoring.

Where do CTIS country submissions create the largest CRO workload?

The dataset included 803 country-trial submission records across 25 European countries. Italy, France, Spain, Germany, and Poland formed the largest CRO-supported CTIS execution footprint: Italy had 78 CRO-supported country-trial records, France 73, Spain 73, Germany 60, and Poland 57.

Poland605795.0%2401,177
Greece4141100.0%117652
Country records reflect CTIS Part II country-level submissions/authorizations, not separate global trials.
Interpretation

The highest CRO workload sits in recurring EU5 and Central/Eastern European activation corridors. Italy, France, Spain, Germany, and Poland account for much of the country-level CTIS operating burden, especially when sponsors need local document handling, site start-up, feasibility, and country-specific implementation after EU submission.

What adjacent demand signals can be answered from the same data?

The strongest adjacent CRO-demand signals were orphan status, paediatric inclusion, digital recruitment, and advanced therapy modality. Orphan haematology trials used CRO support in 46/57 trials, equal to 80.7%, while paediatric trials used CRO support in 37/50 trials, equal to 74.0%.

7/8 gene-therapy haematology Phase III trials had CRO support.
Adjacent signals use trial-level CTIS variables: orphan drug, paediatric trial, recruitment approach, and drug modality.
Interpretation

The clearest adjacent commercial targets are rare-disease haematology, paediatric haematology, digitally supported recruitment models, and gene-therapy programs. These trial types increase dependence on specialist feasibility, patient access, consent localization, vendor coordination, and CTIS country execution.

Executive takeaways

The European haematology Phase III market is not uniformly CRO-dependent. The clearest CRO need emerges when trials cross the 4-country CTIS threshold, enter 7+ country execution, involve orphan or paediatric populations, or require specialized lab, digital, supply, safety, and patient-support vendors.
