Study type
Interventional
Description of intervention(s) / exposure
This trial is for newly diagnosed Multiple Myeloma patients who are eligible for an Autologous Stem Cell Transplant (ASCT). This trial looks at whether the addition of the drug Selinexor to the routine treatment after the transplant prolongs progression free survival and overall survival.

Registered patients who have undergone ASCT and are still eligible for the trial will be randomised no later than 115 days post ASCT.
Patients are randomised to either receive
Lenalidomide 10mg, orally once a day for 21 days
or
Lenalidomide 10mg, orally once a day for 21 days with Selinexor 40mg orally weekly.
If well tolerated, after the first cycle the target dose of Selinexor will be maintained at 40mg, orally, weekly. No dose escalation of Selinexor beyond 40mg/week is permitted.
If well tolerated, after the 4th cycle Lenalidomide can be increased to 15mg, orally, daily for 21 days.
Each cycle is 28 days.
Patients will receive treatment until disease progression.
The clinical trial team will monitor drug returns from the patient and will issue a diary if applicable.

Treatment: Drugs
Comparator / control treatment
.Patients who are randomised to the comparator arm will receive Lenalidomide 10mg, orally once a day for 21 days.
If well tolerated, after the 4th cycle Lenalidomide can be increased to 15mg, orally, daily for 21 days.
Patients will receive treatment until disease progression.

Outcomes
Primary outcome [1] 322901 0
The primary outcome will be to determine whether the addition of selinexor to lenalidomide maintenance therapy post Autologous Stem Cell Transplant for Multiple Myeloma patients increases the proportion of patients who are progression free three years post randomisation. This will be assessed through patient records, blood and bone marrow samples.
Timepoint [1] 322901 0
Three years post randomisation.
Secondary outcome [1] 380183 0
To assess the impact of the addition of selinexor to lenalidomide maintenance on progression free survival. This will be assessed through patient records, blood and bone marrow samples.
Timepoint [1] 380183 0
Date of progression.
Secondary outcome [2] 380342 0
To compare Overall Survival (OS), in patients receieving selinexor lenalidomide maintenance as compared to Lenaidomide maintenance. This will be assessed through patient records, blood and bone marrow samples.

greater than 100mg/L (involved light chain) and an abnormal serum k/l ratio or

surgically sterile OR agree to practice 2 effective methods of contraception at the same
time from 4 weeks before start of study treatment and until 90 days after the last dose of
study drugs OR agree to practice true abstinence when this is in line with the preferred
and usual lifestyle of the subject.
• Male patients, even if surgically sterilized (i.e., status post-vasectomy), must agree to
practice effective barrier contraception during the entire study treatment period and
through 90 days after the last dose of study drug, OR to practice true abstinence when
this is in line with the preferred and usual lifestyle of the subject.

• Subjects must agree not to donate blood, semen or sperm while on study and at least 90
days after treatment discontinuation.
• Subjects must agree not to share their medication and to return unused supplies.
• Patients must meet the following clinical laboratory criteria:
o Absolute neutrophil count (ANC) greater than or equal to 1.5x10^9/L and platelet count
greater than or equal to 100 x10^9/L. Platelet transfusions to help patients meet
eligibility criteria are not allowed.
o Total bilirubin less than or equal to 1.5 x the upper limit of the normal range (ULN)

Key exclusion criteria
• Pregnant or lactating women.

reversible effects of prior chemotherapy.
• Progressive disease post-ASCT.
• Major surgery within 14 days before enrolment.

Safety review:
• 1st Interim Safety Review: After the 10th patients have completed the 2nd cycle of treatment.
• 2nd Interim Safety Review: After the 20th patients have completed the 2nd cycle of treatment.
• 1st futility assessment: After the 30th patient in the Selinexor and lenalidomide arm has completed a minimum of 6 months follow up. If fewer than 20 patients are alive and progression free following this analysis, then consideration will be given to stopping the study or altering the design.
• The primary analysis will occur 3 years after the last patient accrued. Patients will be followed up for 4 years after the last patient enrolment on clinical study.
• The final update on safety and efficacy will be based on additional data collected in the follow-up phase which will finish when the last patient remaining on study has had his/her 3-year follow-up assessment.
