Daratumumab after Stem Cell Transplant in Treating Patients with Multiple Myeloma

Status: Active

Description

This phase II trial studies how well daratumumab after a stem cell transplant works in treating patients with multiple myeloma. Monoclonal antibodies, such as daratumumab, may kill cancer cells that are left after chemotherapy.

  • Subject has active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., Crohn's disease], diverticulitis, celiac disease, irritable bowel disease, or other serious gastrointestinal chronic conditions associated with diarrhea; systemic lupus erythematosus; Wegener syndrome; myasthenia gravis; Graves' disease; rheumatoid arthritis; hypophysitis, uveitis, etc) within the past 3 years prior to the start of treatment; the following are exceptions: * Subjects with vitiligo or alopecia * Subjects with hypothyroidism (e.g., following Hashimoto's disease) stable on hormone replacement * Psoriasis not requiring systemic treatment
  • Subject has known allergies, hypersensitivity, or intolerance to monoclonal antibodies or human proteins, or their excipients
  • Subject has history of primary immunodeficiency
  • Subject is seropositive for human immunodeficiency virus (HIV-1)
  • Active hepatitis A
  • Seropositive for hepatitis B (defined by a positive test for hepatitis B surface antigen [HBsAg]); subjects with resolved infection (I.e., subjects who are HBsAg negative but positive for antibodies to hepatitis B core antigen [anti-HBc] and/or antibodies to hepatitis B surface antigen [anti-HBs] must be screened using real-time polymerase chain reaction [PCR] measurement of hepatitis B virus [HBV] deoxyribonucleic acid [DNA] levels; those who are PCR positive will be excluded); EXCEPTION: Subjects with serologic finding suggestive of HBV vaccination (anti-HBs positivity as the only serologic marker) AND a known history of prior HBV vaccination, do not need to be tested for HBV DNA by PCR
  • Seropositive for hepatitis C (except in the setting of a sustained virologic response [SVR], defined as aviremia at least 12 weeks after completion of antiviral therapy)
  • Subject has any one of the following: * Clinically significant abnormal electrocardiogram (ECG) finding at screening * Congestive heart failure (New York Heart Association class III or IV) * Myocardial infarction within 12 months prior to starting study treatment * Unstable or poorly controlled angina pectoris, including Prinzmetal variant angina pectoris
  • Subject has prior history of malignancies, other than MM, unless the subject has been free of the disease for >= 5 years with the exception of the following malignancies: * Basal cell carcinoma of the skin * Squamous cell carcinoma of the skin * Carcinoma in situ of the cervix * Carcinoma in situ of the breast * Incidental histologic finding of prostate cancer (T1a or T1b using the tumor, node, metastasis [TNM] clinical staging system) or prostate cancer that is curative
  • Any other condition that would, in the opinion of the investigator's judgement, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures
  • Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)

Trial Objectives and Outline

PRIMARY OBJECTIVE:

I. To determine the anti-myeloma activity of single-agent daratumumab post-autologous stem cell transplantation (ASCT) as assessed by progression-free survival at 1 year post ASCT.

SECONDARY OBJECTIVES:

I. To characterize the extent of minimal residual disease (MRD) pre-/post-consolidation treatment segment and at one year during the maintenance treatment segment.

II. To characterize and evaluate toxicities, including type, frequency severity, attribution, and duration (e.g., infections, secondary primary malignancies, peripheral neuropathy).

III. To obtain estimates of overall response rate (stringent complete response [sCR], complete response [CR], very good partial response [VGPR], and partial response [PR]), response duration, depth of response, clinical benefit response, and overall survival.

EXPLORATORY OBJECTIVES:

I. Quantify CD38+ cells from the peripheral blood mononuclear cells (PBMC) fraction, including T, natural killer (NK), and monocytic subsets using pre- and on-daratumumab treatment samples by flow cytometry.

II. Assess possible changes in CD38+ expression, as well as the co-receptor marker CD31, and possible correlation with response using pre- and on-daratumumab treatment samples by flow cytometry.

III. Assess cytokine levels in peripheral blood plasma.

IV. Quantify CD38+ cells from the bone marrow CD-138 negative fractions and acellular fractions, including T, NK, and monocyte subsets using pre- and on-daratumumab treatment samples by flow cytometry.

V. Assess possible changes in CD38+ expression, as well as the co-receptor marker CD31, and possible correlation with response using pre- and on-daratumumab treatment samples by flow cytometry.

VI. Assess cytokine levels in the bone marrow acellular fraction.

VII. Investigate CD38 cellular localization in multiple myeloma cells and extracellular vesicles from blood plasma.

VIII. Assess messenger ribonucleic acid (mRNA) expression in the PBMC, the bone marrow CD130-negative fraction, the T cell fraction, and multiple myeloma cells.

IX. If differences in CD38 expression are found, investigate epigenetic changes in CD38 mRNA expression.

OUTLINE:

Patients undergo standard of care ASCT with a conditioning regimen of melphalan. Beginning 60-120 days after ASCT, patients receive daratumumab intravenously (IV) every week for 8 weeks, every 2 weeks for 16 weeks, and then every 4 weeks for up to 24 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 18 months.
