Interventional
Description of intervention(s) / exposure
SALVAGE: Daratumumab will be given intravenously at a dose of 16mg/kg on days 1, 8, 15 and 22 of each 28-day cycle for cycles 1 and 2, and on days 1 and 15 of each 28-day cycle for cycles 3 and 4. Lenalidomide orally at a dose of 25mg once daily will be given on days 1-21 of each 28-day cycle for cycles 1 to 4. Dexamethasone at a dose of 40mg will be given on days 1, 8, 15 and 22 of each 28-day cycle for cycles 1 to 4.
After completing 3 cycles, patients will undergo a G-CSF mobilised peripheral blood stem cell (PBSC) collection. Following collection, patients will commence cycle 4 and undergo full disease re-evaluation after completion of study treatment.

Autologous Stem Cell Transplant(ASCT): Within 4 to 6 weeks of completion of cycle 4 all patients with greater than or equal to 2 million/kg CD34 cells available will undergo a melphalan 200mg/m2 conditioned ASCT as per standard institutional practice.

CONSOLIDATION: Commencing at between day 100 and 120 post-stem cell transplant patients without evidence of disease progression will commence consolidation. Consolidation cycles 1 to 12 will each be of 28 days duration. In consolidation cycles 1 and 2 patients will receive Daratumumab intravenously at a dose of 16mg/kg on days 1 and 15 and then on day 1 of each of cycles 3 to 12. Lenalidomide orally will be given at a dose of 25mg once daily on days 1-21 of cycles 1 and 2 and at a dose of 10mg once daily on days 1-28 of cycles 3 to 12. Dexamethasone at a dose of 40mg will be given on days 1, 8, 15 and 22 for cycles 1 to 12.

MAINTENANCE: After the completion of 12 cycles of consolidation patients will commence maintenance with Lenalidomide orally 10mg once daily (after 3 months increase to 15 mg/day if tolerated) until disease progression, unacceptable toxicity of the withdrawal of consent, for a maximum of 2 years treatment.

Outcomes
Primary outcome [1] 307229 0
To determine the overall response rate (ORR) to Daratumumab-lenalidomide-dexamtheasone (DRd) salvage treatment (4 cycles of DRd) in newly-diagnosed transplant-eligible patients who have demonstrated either a sub-optimal response or refractoriness to bortezomib-based induction therapy. Response is assessed by International Myeloma Working Group guidelines and responses defined as achieving a partial response or greater.
Timepoint [1] 307229 0
The primary end point will be assessed when last patient recruited has completed disease evaluations following DRd salvage therapy, approximately 5 years post-enrolment.
Secondary outcome [1] 351195 0
To determine the Progression-free Survival (PFS) achieved with Daratumumab-lenalidomide-dexamtheasone (DRd) salvage therapy, Autologous Stem Cell Transplant (ASCT); DRd post-ASCT consolidation and Rituximab-maintenance. Survival status will be noted in the eCRF based on medical records.
Timepoint [1] 351195 0
Patients will be followed for PFS until approximately 5 years post-enrolment
Secondary outcome [2] 351474 0
To determine the Overall Survival (OS) achieved with Daratumumab-lenalidomide-dexamtheasone (DRd) salvage therapy, Autologous Stem Cell Transplant (ASCT); DRd post-ASCT consolidation and Rituximab-maintenance. Survival status will be noted in the eCRF based on medical records.
Timepoint [2] 351474 0
Patients will be followed for OS until approximately 5 years post-enrolment

Eligibility
Key inclusion criteria
1. Male and Female patients, greater than or equal to 18 years of age.
2. Symptomatic NDMM as per IMWG criteria
3. Eligible for high-dose melphalan conditioned ASCT.
4. Patients who have had a sub-optimal response to a bortezomib-based induction therapy, where a sub-optimal response is defined as:
The failure to achieve at least a minimal response (MR) with a minimum of 2 cycles of a prior bortezomib-based induction therapy OR a partial response (PR) with 4 cycles of a prior bortezomib-based induction therapy
OR are bortezomib refractory, that is, have progressed while on bortezomib therapy or within 60 days of receiving their last dose of bortezomib.
5. No contraindication to the use of any of the study drugs.
6. Adequate liver function (total bilirubin less than 2.0x ULN, ALT less than 5.0x ULN) unless considered secondary to MM.
7. Absolute neutrophil count greater than or equal to 1.0 x 109/L.
8. Platelet count greater than or equal to 50 x 109/L (greater than or equal to 30 x 109/L if MM involvement in the marrow is greater than 50%), patients should not have received platelet transfusions within 7 days of the screening platelet count.
9. Hb greater than or equal to 80g/L, red cell transfusions as per institutional protocol are allowed.

Key exclusion criteria
1. Patients who have had myocardial infarction within 6 months prior to enrolment, or NYHA (New York Hospital Association) Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, electrocardiographic evidence of acute ischemia or active conduction system abnormalities.
2. Any other serious or uncontrolled medical or psychiatric illness that could, in the investigators opinion, potentially interfere with the completion of treatment according to this protocol.
3. Known ongoing or active systemic infection, active hepatitis B or C infection, or known human immunodeficiency (HIV) positivity.
4. Subject has significant airways disease according to the following definitions:
a. Subject has known chronic obstructive pulmonary disease (COPD) with a Forced Expiratory Volume in 1 second (FEV1) less than 50% of predicted normal.
b. Subject has had known moderate or severe persistent asthma within the last 2 years, or currently has uncontrolled asthma of any classification. (Note that subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed in the study).
