Phase II trial of ofatumumab, dexamethasone and lenalidomide for high-risk CLL (NCRI CLL210)

II Treatment Closed RLBUHT and UoL EUDRACT No: 2010-019575-29


CLL210 is a new phase II trial of ofatumumab, dexamethasone and lenalidomide for patients with high-risk CLL, defined as 17p- or early failure of fludarabine. Patients who respond to induction treatment and do not have an allogeneic transplant are randomised to lenalidomide maintenance versus no further treatment.

Rituximab containing chemo-immunotherapy has been shown to be ineffective in treating high risk CLL, and improving outcomes for affected patients is an important area of unmet clinical need.

A previous phase II study (CLL206) demonstrated that alemtuzumab-glucocorticoid combination therapy is effective in 17p- CLL, but improvement could be made in terms of response rates and toxicity. CLL210 will evaluate a new induction regimen that differs from CLL206 in three main respects:

- A third drug (lenalidomide - an oral agent with established activity in high-risk CLL) is included.

- The glucocorticoid regimen has been changed to pulsed oral dexamethasone, which contains a lower glucocorticoid dose than used in CLL206.

- Alemtuzumab is replaced by an alternative monoclonal antibody, ofatumumab.

CLL210 originally used dexamethasone, lenalidomide and alemtuzumab in combination. In August 2012, Sanofi withdrew the licence for alemtuzumab as it was planned to market it for other indications. Because of difficulties in obtaining alemtuzumab suitable for trial use recruitment was suspended on 11 September 2012. Because of doubts about alemtuzumab's long term use in CLL, a decision was made to re-launch the study with alemtuzumab replaced by ofatumumab, an alternative monoclonal antibody. It is believed that ofatumumab will be as efficacious as alemtuzumab with reduced toxicity.

Treatment / Intervention

All patients receive 24 weeks of induction treatment consisting of:
- 40mg oral dexamethasone, days 1-4, weeks 1,3,5,7,8,11,13 & 15
- 5mg oral lenalidomide daily weeks 3-4, 10mg oral lenalidomide daily weeks 5-24
- 1000mg intravenous ofatumumab (300mg week 7) day 1 weeks 7-15, 17, 19, 21

Patients who achieve a CR or PR at 24 weeks may elect to receive an allogeneic stem-cell transplant.

Those responders who decide not to have a transplant will be randomised between receiving lenalidomide maintenance until disease progression or receiving no further trial treatment.

Trial Endpoints

The CLL210 trial will investigate the safety and efficacy of combination induction therapy with ofatumumab,dexamethasone and lenalidomide in patients with high risk CLL.

In addition the trial will also examine the value of continuing lenalidomide as post-induction maintenance for patients who achieve a CR or PR.

Primary Outcome

- Complete Response after 6 months of induction therapy
- Progression free rate after 2 years of maintenance therapy.

Secondary Outcomes

- Toxicity
- Overall, complete and partial response rates
- Minimum Residual Disease (MRD) negativity rate
- MRD-negative CR rate
- Overall survival
- Progression-free survival (progression or death)
- Event-free survival (progression, death or further induction treatment)
- Response duration
- Quality of life
- Cumulative dose of individual drugs administered

- Uncontrolled auto-immune haemolytic anaemia or thrombocytopenia

- Total bilirubin >1.5 times upper normal limit (unless due to involvement of liver or a known history of Gilbert's disease) or ALT >2.5 times upper normal limit (unless due to disease involvement of liver)
