Clinical Trial Summary

Multiple myeloma (MM), a plasma cell disorder, is the second most common hematologic malignancy in the U.S. No standard curative therapy has yet been found. A variety of therapeutic measures including high dose melphalan, induction therapy, and continuous therapy have been used but the goal of complete response without relapse has not been achieved. More active treatment regimens and better tools for response assessment are needed.

Description:

This trial will assess the safety and efficacy of an induction therapy using the combination of dexamethasone, lenalidomide (revlimid), daratumumab (Darzalex) and carfilzomib (Kyprolis) to treat patients with newly diagnosed multiple myeloma. The therapy with KRdD (Kyprolis, Revlimid, dexamethasone, Darzalex) will be followed by autologous hematopoietic cell transplantation (auto-HCT) and KRdD consolidation. Duration of therapy will be guided by eradication of minimal residual disease (MRD). The hypothesis is that the KRdD therapy particularly in combination with the auto-HCT will be safe and lead to deep remission. Patients who become MRD- will discontinue therapy (no maintenance therapy) and be actively monitored for resurgence of MRD or clinical relapse.

• Unstable angina or myocardial infarction within 4 months prior to registration, New York Heart Association Class II, III or IV heart failure, uncontrolled angina, history of severe coronary artery disease, severe uncontrolled ventricular arrhythmias, sick sinus syndrome, or electrocardiographic evidence of acute ischemia or Grade 3 conduction system abnormalities unless subject has a pacemaker.

• Cerebrovascular disease manifested as prior stroke at any time or TIA in the 12 months prior to initiation of therapy

• Non-hematologic malignancy within the past 3 years with the exception of a) adequately treated basal cell carcinoma, squamous cell skin cancer, or localized thyroid cancer; b) carcinoma in situ of the cervix or breast; c) prostate cancer of Gleason Grade 6 or less with stable prostate-specific antigen levels; or d) cancer considered cured by surgical resection or unlikely to impact survival during the duration of the study, such as localized transitional cell carcinoma of the bladder or benign tumors of the adrenal or pancreas.

• Significant neuropathy (Grades 3-4, or Grade 2 with pain) within 21 days prior to registration.

• Known history of allergy to Captisol® (a cyclodextrin derivative used to solubilize carfilzomib).

• Subjects with pleural effusions requiring thoracentesis or ascites requiring paracentesis within 21 days prior to registration.

• Contraindication or intolerance to required supportive care medications (Aspirin and Acyclovir).

• Any other clinically significant medical disease or condition that, in the investigator's opinion, may interfere with protocol adherence or a subject's ability to give informed consent.

Related Conditions & MeSH terms

• Multiple Myeloma
• Neoplasms, Plasma Cell

Intervention

Drug:
• KRdD followed by auto-HCT
Dosages of each drug will vary depending on therapy type and cycle number. KRdD therapy will be followed by autologous hematopoietic cell transplantation and KRdD consolidation.
• KRdD only
Dosages of each drug will vary depending on therapy type and cycle number. KRdD therapy will not be followed by autologous hematopoietic cell transplantation but will proceed with KRdD consolidation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Patients With MRD(-) Remissions at the Completion of Consolidation Therapy	The primary endpoint of MRD(-) rate, or percentage of patients with MRD(-) remissions, will be estimated along with two-sided 95% confidence interval using Clopper-Pearson exact method. Simon's optimal two-stage design will be utilized in determining the rate of MRD(-) cases. MRD assessment will be done with ClonoSEQ to identify myeloma-specific sequences.	Baseline until MRD(-) is reached estimated to be up to 15 months.
Secondary	Serious Adverse Events (SAEs) From the KRdD Treatment	The Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be used for this assessment. SAEs include events that are Grade 3 and above; non-serious events are Grades 1-2.	Baseline until the progression of disease or MRD(-) status up to an estimated 15 months.
Secondary	Percentage of Patients With MRD(-) Status at the Completion of Induction Therapy	The primary endpoint of MRD(-) rate will be estimated along with two-sided 95% confidence interval using Clopper-Pearson exact method. Simon's optimal two-stage design will be utilized in determining the rate of MRD(-) cases. MRD assessment will be done with ClonoSEQ to identify myeloma-specific sequences.	Baseline until MRD(-) status estimated at 6 months or until disease progression
Secondary	Percentage of Patients With Auto-HCT That Convert From Positive to Negative MRD	The primary endpoint of MRD(-) rate will be estimated along with two-sided 95% confidence interval using Clopper-Pearson exact method. Simon's optimal two-stage design will be utilized in determining the rate of MRD(-) cases. MRD assessment will be done with ClonoSEQ to identify myeloma-specific sequences.	From baseline up to an estimated 9 months
Secondary	Percentage of Patients Achieving Complete Remission Following Complete Therapy	The primary endpoint of MRD(-) rate will be estimated along with two-sided 95% confidence interval using Clopper-Pearson exact method. Simon's optimal two-stage design will be utilized in determining the rate of MRD(-) cases. MRD assessment will be done with ClonoSEQ to identify myeloma-specific sequences. Complete therapy incorporates induction and consolidation therapy.	Baseline up to 15 months
Secondary	Percentage of Patients That Convert From MRD(-) to MRD(+) Following Treatment Discontinuation	The primary endpoint of MRD(-) rate will be estimated along with two-sided 95% confidence interval using Clopper-Pearson exact method. Simon's optimal two-stage design will be utilized in determining the rate of MRD(-) cases. MRD assessment will be done with ClonoSEQ to identify myeloma-specific sequences.	Baseline to 2 years
Secondary	Progression-free Survival	Progression-free survival is defined as the interval from the start of therapy to the earliest occurrence of the following: disease progression, initiation of anti-myeloma therapy that is not an accepted maintenance therapy of lenalidomide or death from any cause. Kaplan-Meier methods will used.	From date of study entry until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 58 months.
Secondary	Overall Survival	Overall survival is defined as the time from date of study enrollment until death from any cause.	From date of study entry until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 58 months.
