Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All patients will be given Lenalidomide as oral capsules, 25mg, daily on days 1 to 21 followed by a 7-day rest in a 28-day cycle and Dexamethasone as oral 4mg tablets, at a dose of 40mg (20mg for patients age >75 years) on days 1, 8, 15 and 22 in a 28-day cycle at the start of treatment; patients who are already on Lenalidomide and Dexamethasone (Ld) are still able to be enrolled into the study provided that they have not completed 4 cycles of Ld.
After completion of four cycles of Ld, patients who have not achieved at least a partial response (PR) which will be assessed via a blood sample, will have the addition of Isatuximab. In addition to Ld, Isatuximab is to be administered IV at a dose of 10 mg/kg weekly for the first month, then fortnightly (every 14 days) thereafter.
For these patients who remain on Ld, after completion of six cycles of Ld, patients who have not achieved a very good partial response (VGPR) will move onto Isatuximab , Lenalidomide and Dexamaethasone (ILd), whereas patients who have achieved VGPR or greater will remain on Ld. For these patients who remain on Ld, after completion of nine cycles of Ld, patients who have not achieved a complete response (CR) will move onto ILd, whereas patients who have achieved CR or greater will remain on Ld. At any point in time, patients who progress on Ld while on study will also move onto ILd. Treatment will be given until disease progression on ILd or unacceptable toxicity whichever occurs first.

Adherence is monitored through hospital drug administration records and tablet adherence through drug packet return.
