Descriptive Information

• Brief Title: Clarithromycin in Multiple Myeloma Induction Therapy
• Official Title: A Randomized Placebo-controlled Phase II Study of Clarithromycin or Placebo Combined With VCD Induction Therapy Prior to High-dose Melphalan With Stem Cell Support in Patients With Newly Diagnosed Multiple Myeloma
• Brief Summary: This study evaluates the potential synergic anti-myeloma activity of clarithromycin when combined with VCD induction therapy in patients with newly diagnosed multiple myeloma.

Detailed Description

The survival in younger myeloma patients improved in the nineties with the introduction of high-dose melphalan with autologous stem cell support (HDT). However, all patients will eventually experience relapse after HDT and there is a need for improvement of the response after HDT. The choice of induction treatment before HDT affects the outcome after induction therapy as well as the outcome after HDT.

Clarithromycin is a macrolide antibiotic frequently utilized in the treatment of respiratory tract infections and is often used in patients with known hypersensitivity to beta-lactam antibiotic. Besides antibiotic activity, clarithromycin may exert immunomodulatory and anti-inflammatory effects. The toxicity profile of clarithromycin is favourable and the cost is very low.

Studies on cell lines have shown that clarithromycin attenuates autophagy in myeloma cells and a recent study has demonstrated that treatment with clarithromycin enhanced bortezomib-induced cytotoxicity in myeloma cells. Phase II studies without control groups have indicated that clarithromycin might enhance the effect of the thalidomide and lenalidomide. A case-matched analysis compared patients at one centre receiving clarithromycin, lenalidomide and dexamethasone with an equal number of patients at another centre receiving lenalidomide and dexamethasone. This study indicated a favourable effect of clarithromycin with a higher frequency of complete response, very-good-partial-response or better response and progression-free survival. However, there is a need for controlled studies to determine whether clarithromycin might enhance the effect of other myeloma agents.

This randomized placebo-controlled study will include 160 patients with newly diagnosed multiple myeloma eligible for HDT. The study evaluates the potential synergic anti-myeloma activity of clarithromycin when combined with VCD induction therapy in patients with newly diagnosed multiple myeloma, and is conducted by the Danish Myeloma Study Group (DMSG) at seven clinics in Denmark. The first patient was included in May 2015 and enrolment is expected to continue until October 2016. The study ends when the last included patient has been followed for two months after HDT.
