Eligibility and site contacts are on each trial's record. Only the study team can confirm whether a patient is eligible.

Who sponsors Clofarabine clinical trials?

Nantes University Hospital (2), Princess Maxima Center for Pediatric Oncology (1), Ekaterina Laukhtina (1) and Dana-Farber Cancer Institute (1). The number in brackets is how many trials each organisation leads.

Is Clofarabine licensed in Ireland?

Yes. The HPRA medicines list includes 1 single-substance product containing Clofarabine, for example Evoltra 1 mg/ml concentrate for solution for infusion (Sanofi B.V.). A licence does not mean a product is currently marketed or reimbursed; see each product's record.

Is there a Clofarabine shortage?

Not in the lists we track: Clofarabine has no entry in the EMA, FDA or German BfArM shortage registers as of their latest sync.

How this page is built

Everything on this page is copied from public ClinicalTrials.gov registry records โ€” it is not written from memory, and nothing here describes how Clofarabine works or whether it is effective. Each trial links to its own record so you can check it yourself.

This page is built automatically: a daily sync job reads the registry records behind our country trial registers, collects every trial that lists Clofarabine (or a registered synonym) as a drug or biological intervention, and tabulates the registry fields directly. Placebos and generic comparators are excluded. There is no AI drafting and no per-compound editorial pass, and the page has not been clinically reviewed. The “last verified” date above is the timestamp of that sync, not a review date. Our general editorial approach is described in our editorial standards and corrections policy. The ClinicalTrials.gov data on this page was last retrieved on 27 Sep 2026.

Please verify before you rely on this. This page is general information for life-science and pharmaceutical professionals. It is not medical advice, and it has not been reviewed by a clinician โ€” our editorial team holds life-science qualifications, not clinical ones. It is not exhaustive and may not reflect the most recent label change. Always check the official prescribing information (US Prescribing Information or EU SmPC) and speak to your doctor or pharmacist before acting on anything here. Drugs in the same class are not automatically interchangeable, and approvals, brand names and indications differ between the US, the EU/Ireland (EMA/HPRA) and other regions. Spotted an error?
