RESUMO

BACKGROUND: Daratumumab-hyaluronidase-fihj (Dara-SQ) is frequently used in the treatment of plasma cell disorders and is associated with improved outcomes. Dara-SQ was shown to be non-inferior to intravenous daratumumab (Dara-IV) in efficacy, safety, and associated with fewer administration-related reactions (ARRs). Despite the lower ARR risk with Dara-SQ, package labeling still recommends indefinite premedication. In this study, we investigated the safety of premedication discontinuation after one cycle of Dara-SQ. MATERIALS AND METHODS: This pre-post interventional quality improvement study included all patients aged 18 years and older diagnosed with multiple myeloma or light chain (AL) amyloidosis who received at least one dose of Dara-SQ. Patients in Arm 1 received Dara-SQ per package labeling, while patients in Arm 2 had premedication omitted (excluding dexamethasone) after cycle 1. The primary endpoint was the incidence of ARR after cycle 1. Overall ARR rate and therapy time saved were also evaluated. RESULTS: A total of 102 patients (63 in Arm 1 and 39 in Arm 2) were included. There were zero reactions in either arm after cycle 1 across 1479 Dara-SQ doses administered over a 30-month period with or without premedication omission. The overall ARR rate was 2.9% (3/102), which all occurred prior to premedication omission. Therapy timed saved from premedication omission was 194 hours in a 6-month period, equating to approximately $140 000 USD. CONCLUSION: ARRs to Dara-SQ were rare, mild, and occurred during cycle 1 prior to premedication omission. Omission of noncorticosteroid premedication is safe, feasible, and carries substantial time and cost savings for patients and infusion centers.

RESUMO

We evaluated the efficacy and safety of 24 cycles of Dara in combination with carfilzomib (K), lenalidomide (R), and dexamethasone (d) without autologous stem cell transplant (ASCT) in newly diagnosed multiple myeloma (NDMM) irrespective of ASCT eligibility in a single-arm, phase II study. The primary endpoint was the rate of stringent complete response (sCR) and/or measurable residual disease (MRD) < 10-5 by next-generation sequencing (NGS) at the end of cycle 8 (C8). MRD was also assessed on peripheral blood samples using both the EXENT® system and liquid chromatography-mass spectrometry (LC-MS). Forty-two patients entered the treatment phase; forty were evaluable for the primary endpoint. The rate of sCR and/or MRD < 10-5 following C8 was 30/40 (75%), meeting the statistical threshold for efficacy. The 10-6 MRD negative rate improved with treatment beyond C8. Agreement between EXENT® and NGS was high and increased over time; agreement between LC-MS and NGS was lower. The estimated 3-year progression-free survival progression-free survival was 85%, and 3-year overall survival was 95%. Upper respiratory infections occurred in 67% (7% grade 3-4). There were no treatment-related deaths. Extended frontline Dara-KRd induced a high rate of sCR and/or MRD negativity; the rate and depth of MRD negativity improved beyond C8.

RESUMO

Mass spectrometry (MS) can detect multiple myeloma-derived monoclonal proteins in peripheral blood (PB) with high sensitivity, potentially serving as a PB assay for measurable residual disease (MRD). This study evaluated the significance of PB MS MRD negativity during post-transplant therapy in patients with newly diagnosed multiple myeloma. Serum samples from 138 patients treated in the phase 3 ATLAS trial of post-transplant maintenance with either carfilzomib, lenalidomide, dexamethasone or lenalidomide alone were analyzed using EXENT MS methodology. We established feasibility of measuring MRD by MS in PB in the post-transplant setting, despite unavailability of pre-treatment calibration samples. There was high agreement between MRD by MS in PB and paired BM MRD results at the 10-5 threshold, assessed by either next generation sequencing (NGS) or multiparameter flow cytometry (MFC) (70% and 67%, respectively). Agreement between PB MS and both BM MRD methods was lowest early after transplant and increased with time. MS negativity was associated with improved progression-free survival (PFS), which in landmark analysis reached statistical significance after 18 cycles post-transplant. Combined PB/BM MRD negativity by MFC or NGS was associated with superior PFS compared to MRD negativity by only one modality. Sustained MS negativity carried similar prognostic performance to sustained BM MRD negativity at the 10-5 threshold. Overall, post-transplant MS assessment was feasible and provided additional prognostic information to BM MRD negativity. Further studies are needed to confirm the role and optimal timing of MS in disease evaluation algorithms. The ATLAS trial is registered at www.clinicaltrials.gov as #NCT02659293.

RESUMO

Previous studies suggest that postautologous stem cell transplant (ASCT) recovery of polyclonal immunoglobulin from immunoparesis in patients with multiple myeloma is a positive prognostic marker. We performed a longitudinal analysis of polyclonal immunoglobulin concentrations and unique B-cell sequences in patients enrolled in the phase 3 ATLAS trial that randomized 180 subjects to either carfilzomib, lenalidomide, dexamethasone (KRd) or lenalidomide (R) maintenance. In the KRd arm, standard-risk patients with minimal residual disease negativity after six cycles de-escalated to R alone after cycle 8. One year from the initiation of maintenance at least partial recovery of polyclonal immunoglobulin was observed in more patients on the R arm (58/66, p < 0.001) and in those who de-escalated from KRd to R (27/38, p < 0.001) compared to the KRd arm (9/36). In patients who switched from KRd to R, the concentrations of uninvolved immunoglobulin and the number of B-cell unique sequences increased over time, approaching values observed in the R arm. There were no differences in progression-free survival between the patients with at least partial immunoglobulin recovery and the remaining population. Our analysis indicates that patients receiving continuous therapy after ASCT experience prolonged immunoparesis, limiting prognostic significance of polyclonal immunoglobulin recovery in this setting.

RESUMO

PURPOSE OF REVIEW: Therapeutic advancements in multiple myeloma have led to increasingly deeper and more durable responses, creating a need for highly sensitive and applicable techniques for measurable residual disease (MRD) assessment. Bone marrow assays can deeply assess for MRD, but it is not conducive to performing frequent and dynamic evaluations, which may be needed for MRD-adapted treatment approaches. Recently, numerous techniques for MRD assessment in peripheral blood have come under investigation, and their integration into routine clinical practice is eagerly anticipated. RECENT FINDINGS: The identification of circulating tumor cells (CTCs), evaluation of cell-free DNA, and measuring monoclonal protein concentration with mass spectrometry are promising research areas for assessing myeloma in peripheral blood. CTCs assessment and cell-free DNA may carry prognostic significance, but they lack the sensitivity of bone marrow-based techniques. Mass spectrometry has already been implemented in clinical practice in certain centers, but its full potential has yet to be fully realized. This review focuses on recent developments in these fields, emphasizing the potential future roles of these assessments. SUMMARY: MRD assessment in peripheral blood is still in the development stage but holds promise for not only complementing bone marrow based evaluations but also potential for improving sensitivity.

RESUMO

We conducted a phase 1/2 study of carfilzomib, pomalidomide, and dexamethasone (KPd) and KPd with daratumumab (Dara-KPd) in relapsed/refractory multiple myeloma. The primary end points were identification of a maximum tolerated dose (MTD) of KPd for phase 1, and rates of overall response (ORR) and near complete response (nCR) after 4 cycles of KPd and Dara-KPd, respectively, for phase 2. The MTD for KPd was carfilzomib 20/27 mg/m2 on days 1, 2, 8, 9, 15, and 16 (cycles 1-8) and days 1, 2, 15, and 16 for cycles 9 and beyond; oral pomalidomide 4 mg on days 1 to 21; and oral dexamethasone 40 mg weekly in 28-day cycles. Sixty-six patients received KPd, including 34 at the MTD. The ORR after 4 cycles of KPd at the MTD was 27/34 (79%; 95% confidence interval [CI], 62%-91%), meeting the statistical threshold for efficacy. At a median follow-up of 44 months, the median progression-free survival (PFS) was 13 months and overall survival (OS) 44 months. Twenty-eight patients received Dara-KPd. The rate of nCR or better after 4 cycles was 11/28 (39%; 95% CI, 22%-59%), meeting the statistical threshold for efficacy. As the best response to Dara-KPd, the ORR was 25/28 (89%) and the rate of measurable residual disease negativity by flow cytometry (10-5) was 17/26 (65%). At a median follow-up of 26 months, the median PFS and OS for Dara-KPd were not reached. Dara-KPd induced deeper and more durable responses than KPd without compromising safety in a predominantly high-risk, lenalidomide-refractory population, warranting further evaluation of this quadruplet. This trial is registered at www.clinicaltrials.gov as #NCT01665794.

RESUMO

BACKGROUND: Lenalidomide is a cornerstone of maintenance therapy in patients with newly diagnosed multiple myeloma after autologous stem-cell transplantation. We aimed to compare the efficacy and safety of maintenance therapy with carfilzomib, lenalidomide, and dexamethasone versus lenalidomide alone in this patient population. METHODS: This study is an interim analysis of ATLAS, which is an investigator-initiated, multicentre, open-label, randomised, phase 3 trial in 12 academic and clinical centres in the USA and Poland. Participants were aged 18 years or older with newly diagnosed multiple myeloma, completed any type of induction and had stable disease or better, autologous stem-cell transplantation within 100 days, initiated induction 12 months before enrolment, and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients were randomly assigned (1:1) using permuted blocks of sizes 4 and 6 and a web-based system to receive up to 36 cycles of carfilzomib, lenalidomide, and dexamethasone (28-day cycles of carfilzomib 20 mg/m2 administered intravenously in cycle one on days 1 and 2 then 36 mg/m2 on days 1, 2, 8, 9, 15, and 16 in cycles one to four and 36 mg/m2 on days 1, 2, 15, and 16 from cycle five up to 36 [per protocol]; lenalidomide 25 mg administered orally on days 1-21; and dexamethasone 20 mg administered orally on days 1, 8, 15, and 22) or lenalidomide alone (10 mg administered orally for the first three cycles and then at the best tolerated dose [≤15 mg for 28 days in 28-day cycles]) until disease progression or unacceptable toxicity as maintenance therapy. After 36 cycles, patients in both treatment groups received lenalidomide maintenance. Randomisation was stratified by response to previous treatment, cytogenetic risk factors, and country. Investigators and patients were not masked to treatment allocation. Patients in the carfilzomib, lenalidomide, and dexamethasone group with no detectable minimal residual disease after cycle six (as per International Myeloma Working Group criteria) and standard-risk cytogenetics were switched to lenalidomide maintenance as of cycle nine. The primary endpoint was progression-free survival in the intention-to-treat population (defined as all randomly assigned patients). Safety was analysed in all randomly assigned patients who received at least one dose of study treatment. This unplanned interim analysis was triggered by the occurrence of 59 (61%) of the expected 96 events for the primary analysis and the results are considered preliminary. This trial is registered with ClinicalTrials.gov, NCT02659293 (active, not recruiting) and EudraCT, 2015-002380-42. FINDINGS: Between June 10, 2016, and Oct 21, 2020, 180 patients were randomly assigned to receive either carfilzomib, lenalidomide, and dexamethasone (n=93) or lenalidomide alone (n=87; intention-to-treat population). The median age of patients was 59·0 years (IQR 49·0-63·0); 84 (47%) patients were female and 96 (53%) were male. With a median follow-up of 33·8 months (IQR 20·9-42·9), median progression-free survival was 59·1 months (95% CI 54·8-not estimable) in the carfilzomib, lenalidomide, and dexamethasone group versus 41·4 months (33·2-65·4) in the lenalidomide group (hazard ratio 0·51 [95% CI 0·31-0·86]; p=0·012). The most common grade 3 and 4 adverse events were neutropenia (44 [48%] in the carfilzomib, lenalidomide, and dexamethasone group vs 52 [60%] in the lenalidomide group), thrombocytopenia (12 [13%] vs six [7%]), and lower respiratory tract infections (seven [8%] vs one [1%]). Serious adverse events were reported in 28 (30%) patients in the carfilzomib, lenalidomide, and dexamethasone group and 19 (22%) in the lenalidomide group. One treatment-related adverse event led to death (respiratory failure due to severe pneumonia) in the carfilzomib, lenalidomide, and dexamethasone group. INTERPRETATION: This interim analysis provides support for considering carfilzomib, lenalidomide, and dexamethasone therapy in patients with newly diagnosed multiple myeloma who completed any induction regimen followed by autologous stem-cell transplantation, which requires confirmation after longer follow-up of this ongoing phase 3 trial.

RESUMO

Importance: Treatment of newly diagnosed multiple myeloma (NDMM) with a quadruplet regimen consisting of a monoclonal antibody, proteasome inhibitor, immunomodulatory imide, and corticosteroid has been associated with improved progression-free survival (PFS) compared with triplet regimens. The optimal quadruplet combination, and whether this obviates the need for frontline autologous stem cell transplant (ASCT), remains unknown. We evaluated elotuzumab and weekly carfilzomib, lenalidomide, and dexamethasone (Elo-KRd) without ASCT in NDMM. Objective: To investigate the efficacy of Elo-KRd using a measurable residual disease (MRD)-adapted design in NDMM regardless of ASCT eligibility. Design, Setting, and Participants: This multicenter, single-arm, phase 2 study enrolled patients between July 2017 and February 2021. Median follow-up was 29 months. Interventions: Twelve to 24 cycles of Elo-KRd; consecutive MRD-negative results at 10-6 by next-generation sequencing (NGS) after cycles 8 (C8) and 12 determined the duration of Elo-KRd. This was followed by Elo-Rd (no carfilzomib) maintenance therapy until disease progression. Main Outcomes and Measures: The primary end point was the rate of stringent complete response (sCR) and/or MRD-negativity (10-5) after C8 Elo-KRd. Secondary end points included safety, rate of response, MRD status, PFS, and overall survival (OS). As an exploratory analysis, MRD was assessed using liquid chromatography mass spectrometry (MS) on peripheral blood samples. Results: Forty-six patients were enrolled (median age 62 years, 11 [24%] aged >70 years). Overall, 32 (70%) were White, 6 (13%) were Black, 3 (6%) were more than 1 race, and 5 (11%) were of unknown race. Thirty-three (72%) were men and 13 (28%) were women. High-risk cytogenetic abnormalities were present in 22 (48%) patients. The rate of sCR and/or MRD-negativity after C8 was 26 of 45 (58%), meeting the predefined statistical threshold for efficacy. Responses deepened over time, with the MRD-negativity (10-5) rate increasing to 70% and MS-negativity rate increasing to 65%; concordance between MRD by NGS and MS increased over time. The most common (>10%) grade 3 or 4 adverse events were lung and nonpulmonary infections (13% and 11%, respectively). There was 1 grade 5 myocardial infarction. The estimated 3-year PFS was 72% overall and 92% for patients with MRD-negativity (10-5) at C8. Conclusions and Relevance: An MRD-adapted design using elotuzumab and weekly KRd without ASCT showed a high rate of sCR and/or MRD-negativity and durable responses. This approach provides support for further evaluation of MRD-guided deescalation of therapy to decrease treatment exposure while sustaining deep responses. Trial Registration: ClinicalTrials.gov Identifier: NCT02969837.

RESUMO

Pooled analyses of four single-arm phase 1 and 2 studies (NCT01816971, NCT02405364, NCT01029054, NCT01402284) investigated the clinical effectiveness of carfilzomib-lenalidomide-dexamethasone (KRd) in newly diagnosed multiple myeloma (NDMM). Patients who did (Cohort 1; n = 122) and did not (Cohort 2; n = 99) undergo autologous stem cell transplant (high-dose melphalan [HDM]-ASCT) were included. Patients received a 28-day cycle of induction KRd. The rate of very good partial response or better, the primary endpoint, was 93% in Cohort 1 and 90% in Cohort 2. Two-year progression-free survival and overall survival rates were 88% and 96% for Cohort 1, and 85% and 97% for Cohort 2. At least 90% of patients in each cohort reported ≥1 grade 3 or 4 treatment-emergent adverse events. Subgroup analyses by age, International Staging System stage, and cytogenetic risk were consistent with the overall population. KRd is an effective and tolerable treatment option for patients with NDMM regardless of HDM-ASCT eligibility.

RESUMO

BACKGROUND: Patients with high-risk, newly diagnosed multiple myeloma (HR-NDMM) who are ineligible for autologous stem cell transplant (ASCT) have limited first-line treatment options. Recent meta-analyses evaluating the impact of incorporating daratumumab in the backbone regimen on progression-free survival (PFS) have found mixed results in these patients. MATERIALS AND METHODS: A pooled analysis of patient-level data for ASCT-ineligible patients with HR-NDMM [ie, del(17p), t(4;14), t(14;16)] from the MAIA and ALCYONE trials; stratified by study identifier and adjusting for cytogenetic abnormality subtype, baseline performance status, International Staging System stage, myeloma type, and renal impairment; was conducted. Impact of daratumumab on PFS and rates of complete response or better (≥CR), minimal residual disease (MRD)-negative CR, very good partial response or better (≥VGPR), and overall response (ORR) was compared to control. RESULTS: Among 101 patients in the daratumumab and 89 patients in the control cohort, median follow-up was 43.7 months. Daratumumab reduced the risk of progression or death by 41% (adjusted hazard ratio for PFS [95% confidence interval (CI)] = 0.59 [0.41-0.85]) versus control. At 36 months, the estimated proportion of patients who did not progress and were still alive was 41.3% in the daratumumab and 19.9% in the control cohort. Rates of ≥CR (41.6% vs. 22.5%), MRD-negative CR (24.8% vs. 5.6%), ≥VGPR (75.2% vs. 46.1%), and ORR (92.1% vs. 74.2%) were higher for daratumumab versus control. CONCLUSION: These findings demonstrate that incorporation of daratumumab in frontline treatment regimens reduced the risk of progression or death and improved response rates among ASCT-ineligible HR-NDMM patients.

RESUMO

The multiple myeloma treatment landscape has evolved considerably over the last 20 years with the development of multiple therapies with novel mechanisms of action and new combination regimens. However, the recent failure of several large phase III trials, coupled with an increased understanding of the mutational landscape of multiple myeloma has provided opportunities to explore optimal strategies for future multiple myeloma drug development. The Office of Oncologic Diseases at the FDA held an educational symposium, "Drug Development in MM-Project 2025," in November 2019. The symposium brought together select U.S.-based academic thought leaders in the field of multiple myeloma to explore issues relevant to regulatory science in the field, including considerations for trial design, combination strategies, control arms, and precision medicine. This article summarizes the highlights of this educational symposium held at the FDA, including discussions on the future development of novel drugs and drug combinations and biomarker-directed therapies for patients with multiple myeloma.

RESUMO

Minimal residual disease (MRD) assessment is incorporated in an increasing number of multiple myeloma (MM) clinical trials as a correlative analysis, an endpoint or even as a determinant of subsequent therapy. There is substantial heterogeneity across clinical trials in how MRD is assessed and reported, creating challenges for data interpretation and for the design of subsequent studies. We convened an international panel of MM investigators to harmonize how MRD should be assessed and reported in MM clinical trials. The panel provides consensus on which MM trials should include MRD, the recommended time points for MRD assessment, and expected analytical validation for MRD assays. We subsequently outlined parameters for reporting MRD results implementing the intention-to-treat principle. The panel provides guidance regarding the incorporation of newer peripheral blood-based and imaging-based approaches to detection of residual disease. Recommendations are summarized in 13 consensus statements that should be followed by sponsors, investigators, editors, and reviewers engaged in designing, performing, and interpreting MM trials.

RESUMO

BACKGROUND: Autologous hematopoietic stem cell transplant (autoHCT) is a mainstay of treatment for multiple myeloma and non-Hodgkin lymphoma but is underutilized in older adults. We investigated the association of vulnerabilities identified by a geriatric assessment (GA)-guided multidisciplinary clinic (MDC) on the receipt of autoHCT and evaluated its ability to predict outcomes in older autoHCT candidates. METHODS: Patients 50+ years received GA-informed optimization recommendations: 'decline' if unlikely to realize benefits of autoHCT, 'defer' if optimization necessary before autoHCT, and 'proceed' if autoHCT could proceed without delay. We compared characteristics and outcomes of autoHCT recipients (n = 62) to non-autoHCT patients (n = 29) and evaluated GA deficits on outcomes. RESULTS: 91 patients were evaluated; the MDC recommendation was 'decline' for 5 (6%), 'defer' for 25 (27%), and 'proceed' for 61 (67%). AutoHCT recipients had fewer GA-rated impairments relative to non-autoHCT patients, as did patients with a 'proceed' recommendation relative to 'defer'. Among autoHCT recipients, 1-year and 3-year non-relapse morality (NRM) was 0% and 5%, and there was no difference in length of hospitalization, readmission rate, or mortality after transplant by MDC recommendation. Frail grip strength and poor performance status were associated with inferior post-autoHCT progression-free survival and overall survival. CONCLUSIONS: Patients pursuing autoHCT after MDC-directed optimization achieved excellent outcomes, including patients deferred but ultimately receiving autoHCT. GA-identified functional deficits, especially frail grip strength, may improve risk stratification in older autoHCT candidates. Employing a GA earlier in the disease trajectory to inform early referral to an MDC may increase autoHCT safety and utilization in older patients.

RESUMO

Findings on racial differences in survival in multiple myeloma (MM) have been inconclusive. We assessed differences in outcomes between White and Black individuals among 639 newly diagnosed MM patients in the MM Research Foundation CoMMpass registry with baseline cytogenetic data. Survival curves were constructed using the Kaplan-Meier method. Hazard ratios and 95% confidence intervals were derived from Cox proportional hazard regression models. Age, gender, and stage were similar between Whites (n = 526) and Blacks (n = 113). Blacks had inferior overall survival (OS) compared with Whites and were less likely to receive triplet therapies or frontline autologous stem cell transplant (ASCT). The following factors were significantly associated with inferior OS in multivariate analysis: higher international staging system (ISS) score, ≥1 or ≥2 high-risk cytogenetic abnormalities (HRCA), high-risk gene expression profile (GEP), and lack of ASCT. Multivariate analysis in the Black subset found that only lack of ASCT was significantly associated with inferior OS. The receipt of both triplet induction and ASCT only partly abrogated the effect of race on survival. HRCA did not track with survival in Blacks, emphasizing the need for race-specific risk prognostication schema to guide optimal MM therapy.

RESUMO

In this phase 2 multicenter study, we evaluated the incorporation of autologous stem cell transplantation (ASCT) into a carfilzomib-lenalidomide-dexamethasone (KRd) regimen for patients with newly diagnosed multiple myeloma (NDMM). Transplant-eligible patients with NDMM received 4 cycles of KRd induction, ASCT, 4 cycles of KRd consolidation, and 10 cycles of KRd maintenance. The primary end point was rate of stringent complete response (sCR) after 8 cycles of KRd with a predefined threshold of ≥50% to support further study. Seventy-six patients were enrolled with a median age of 59 years (range, 40-76 years), and 35.5% had high-risk cytogenetics. The primary end point was met, with an sCR rate of 60% after 8 cycles. Depth of response improved over time. On intent-to-treat (ITT), the sCR rate reached 76%. The rate of minimal residual disease (MRD) negativity using modified ITT was 70% according to next-generation sequencing (<10-5 sensitivity). After median follow-up of 56 months, 5-year progression-free survival (PFS) and overall survival (OS) rates were 72% and 84% for ITT, 85% and 91% for MRD-negative patients, and 57% and 72% for patients with high-risk cytogenetics. For high-risk patients who were MRD negative, 5-year rates were 77% and 81%. Grade 3 to 4 adverse events included neutropenia (34%), lymphopenia (32%), infection (22%), and cardiac events (3%). There was no grade 3 to 4 peripheral neuropathy. Patients with NDMM treated with KRd with ASCT achieved high rates of sCR and MRD-negative disease at the end of KRd consolidation. Extended KRd maintenance after consolidation contributed to deepening of responses and likely to prolonged PFS and OS. Safety and tolerability were manageable. This trial was registered at www.clinicaltrials.gov as #NCT01816971.

RESUMO

INTRODUCTION: Improvements in cancer treatment and supportive care, as well as the approval of oral chemotherapy medications over the past decade, have resulted in an increasing number of cancer patients being treated in outpatient settings. Transitioning cancer treatments to the outpatient setting places greater emphasis on proper medication counseling and optimal management of adverse effects. We therefore evaluated the clinical and financial impact of an oncology clinical pharmacist specialist in an interdisciplinary multiple myeloma clinic by using a validated scoring tool. METHODS: The oncology clinical pharmacist specialist was available for consult by the multiple myeloma clinic staff. The pharmacist may be consulted for any medication-related inquiry. On the basis of the consult, the pharmacist categorized interventions into 12 predefined intervention categories. RESULTS: Implementation of a clinical pharmacy specialist into a multiple myeloma clinic over 39 clinic days resulted in 241 patient consults and 474 interventions made by the pharmacist. The most frequent interventions made by the pharmacist were medication teaching (n = 97), dose adjustments (n = 82), and medication reconciliation (n = 63). The value of interventions made by the pharmacist during the study period was $189,441, with a predicted annual value of $757,764. CONCLUSION: The addition of an oncology pharmacist to an outpatient multiple myeloma clinic can improve clinical and financial outcomes.
