Corona Virus





Wat betreft HOVON:

Het HOVON Data Center (HDC) en dus ook de HOVON Safety desk blijft onveranderd operationeel om de veiligheid van de patiënten in een HOVON studie te waarborgen.

De levering van studiemedicatie wordt nauwlettend opgevolgd en indien nodig zal tijdig hierover bericht worden.

Centrale lab faciliteiten zijn onveranderd operationeel. Vooralsnog is het mogelijk om patiënten in de HOVON studies te includeren.


Wat betreft deelnemende site:

Indien jullie nav COVID-19 situatie de inclusie voor een studie tijdelijk stopzetten graag het HDC per email hierover informeren (mail naar

Verder, indien er per protocol bepaalde studie visites/handelingen niet (kunnen) plaatsvinden nav COVID-19 situatie graag documenteren in de patiënten file.



Gegeven de situatie rondom Corona virus zijn het HOVON Centraal Bureau (HCB) en het HOVON Data Center (HDC) tijdelijk telefonisch niet bereikbaar.

Graag alle (urgente) vragen via email, deze zullen zsm door het team opgepakt en verwerkt worden. Indien terugbellen noodzakelijk is, graag dit aangeven in de email. Wij hopen op jullie begrip voor deze situatie.

Voor studie specifieke vragen kun je contact opnemen met de trial manager van de studie of via het algemene HDC email adres ( – voeg HOVON studie nr toe).



Met vriendelijke groet, Marleen Breems (HOVON General Director) en Bianca Backx (manager HDC)

Ho88 news

21 DEC 2012

The study is closed for entry of new patients, because it has reached its target of 50 patients.

04 DEC 2012

Within a few months we expect to include the last patient in the HOVON88. With the current inclusion rate we expect that the study will be closed for entry of new patients in February 2013. In order to prevent the situation where a patient has been informed and invited to participate but cannot be registered anymore because of closure of the study in the time needed for the informed consent, please inform HOVON Data Center (HDC) if you have a patient that will be informed about the HOVON 88 CLL study. These patients will be put on a list. When, after screening, the patient is eligible, HOVON Data Center is to be called to see whether it is still possible to register the patient in study.


You will be informed when the target of 50 patients has been reached and the study will be closed for inclusion of new patients. Until then please inform us if you intend to inform a new patient about the study.


09-08-11: Implementation of protocol amendment (protocol version 28MAY2011) in The Netherlands, Belgium followed at 23-08-11.


10-12-10: Please give antibiotics prophylaxis according to local procedures during R-DHAP therapy. Protocol amendment will follow.


05-06-09: SOP MRD measurement and analysis, LDM + LI meeting presentations added to Other documents.


For the Ho88 CLL study there is no central laboratory involved.

MRD by flowcytometry has to be performed by your own laboratory (or collaboration with other hospital)

PB or BM samples for future molecular studies have to be preserved in liquid nitrogen at your own laboratory.

Study objectives

Primary objective:
To assess, on an intention-to-treat basis, the efficacy and safety of a treatment protocol including salvage chemoimmunotherapy (R-DHAP) followed, in the absence of progression, by RIC alloSCT from sibling or unrelated donors, in high-risk CLL patients as defined in chapter 8.1.1, as measured by the progression free survival as defined in chapter 14.

Secondary objectives:
To assess the safety and toxicity of three courses of R-DHAP
To assess the response to three courses of R-DHAP.
To assess PFS and OS after alloSCT.
To asses PFS and OS after maximally 6 R-DHAP in case no alloSCT was performed
To assess disease status at two years after SCT.
To assess the incidence and course of MRD in patients with CR
To assess overall survival from registration.
To assess the incidence of complete, partial and no engraftment.
To evaluate the incidence and severity of acute and chronic GVHD, and of other treatment related toxicity;
To evaluate the response of progressive disease or increasing MRD to lowering of immunosuppression or DLI.
To assess the time to next treatment excluding MRD triggered lowering of immunosuppression or DLI.
To assess the prognostic value of risk factors at entry including IgH mutation status and karyotypic abnormalities with respect to PFS.
To assess the functionality of mutated p53 at entry and at relapse.
