Abstract
This multicenter, open-label, single-arm trial (ClinicalTrials.gov, NCT05236621) was conducted to confirm the efficacy and safety of generic pomalidomide plus dexamethasone in Chinese patients with relapsed or refractory multiple myeloma (RRMM). Total 79 eligible RRMM patients were planned to be included. Patients were treated with generic pomalidomide (4 mg daily on days 1-21, orally) and low-dose dexamethasone (40 mg/day on days 1, 8, 15, and 22, orally; 20 mg for patients aged > 75 years) in 28-day cycles until disease progression with a maximum treatment duration of 2 years. The primary endpoint is the overall response rate (ORR) assessed by the independent review committee per the 2016 International Myeloma Working Group guidelines. A total of 85 eligible patients were included in this study from 32 centers in China, with a median age of 62.0 (range, 39-76) years, a median prior line of therapy of 4 (range, 1-16), and 41.2% patients with high-risk cytogenetics. The ORR was 38.8% (95% confidence interval (CI), 28.44-50.01). The disease control rate was 67.1% (95% CI, 56.02-76.87), meanwhile, the median progression-free survival was 5.55 months (95% CI, 3.68-7.52). Among the treatment-related adverse events (TRAEs), infective pneumonia (17.6%) was the most frequent non-hematologic adverse event, while a decrease in neutrophil count (52.9%) was the most common grade ≥ 3 TRAE. The study results indicated that the generic pomalidomide demonstrated consistent efficacy and a safety profile similar to the branded pomalidomide when combined with low-dose dexamethasone in Chinese RRMM patients.Registration number ClinicalTrials.gov NCT05236621, retrospectively registered on February 11, 2022.

[PMID: 36881059 PMCID: PMC10026632 DOI: 10.21873/invivo.13168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 02/05/2023] [Accepted: 02/07/2023] [Indexed: 03/08/2023]
Abstract
BACKGROUND/AIM Pomalidomide is an immunomodulatory drug that is used to treat multiple myeloma. We examined the time-to-onset and outcome of lung adverse events (LAEs) related to pomalidomide in Japanese patients based on information obtained from the spontaneous reporting system of the Japanese Adverse Drug Event Report database (JADER) of the Pharmaceuticals and Medical Devices Agency. PATIENTS AND METHODS We analyzed adverse events (AEs) reports recorded between April 2004 and March 2021 from JADER. Data on LAEs were extracted, and the relative risk of AEs was estimated using the reporting odds ratio and 95% confidence interval. We analyzed 1,772,494 reports and identified 2,918 reports of AEs caused by pomalidomide. Of these, 253 LAEs were reportedly associated with pomalidomide. RESULTS Signals were detected for five LAEs: pneumonia, pneumocystis jirovecii pneumonia, bronchitis, pneumonia bacterial, and pneumonia pneumococcal. Pneumonia was the most frequently mentioned condition (68.8%). The median time-to-onset of pneumonia was 66 days, but some cases of pneumonia occurred as late as 20 months after the start of administration. Fatal outcomes were observed in two of the five AEs wherein signals were detected and were due to pneumonia and bacterial pneumonia. CONCLUSION Serious outcomes can occur after pomalidomide administration. It has been suggested that these LAEs occur relatively early after pomalidomide administration. Since some situations can result in fatal consequences, patients should be monitored for the emergence of these AEs over a prolonged period of time, especially for pneumonia.

Abstract
Even though multiple myeloma (MM) is still considered incurable, the therapeutic management of this disease has undergone a major transformation over the last two decades, with several new classes of therapeutics and diverse options for their combined use in many different regimens that have contributed to major improvement in overall survival of patients. This review discusses key themes underlying the pharmacological and immune-based therapies that represent the cornerstones of this progress. A major part of the clinical progress achieved by these classes' therapeutics has depended on the targeting of molecular pathways with distinct or preferential roles for the biology of plasma cells-normal or malignant-and the ability of many of these agents to be incorporated into combination regimens that exhibit enhanced antimyeloma responses, without precipitating acceptable levels of toxicity. This review also discusses why these advances have not yet translated into curative outcomes and how these remaining barriers could be overcome.

Abstract
Pomalidomide is an immunomodulatory drug used for relapsed and refractory multiple myeloma (RRMM). Hypothyroidism is an uncommon side effect of pomalidomide. We present a 70-year-old male patient with RRMM on daratumumab, pomalidomide and dexamethasone, who presented with 2 weeks of fatigue. Laboratory values showed sodium of 120 mEq/L, plasma osmolarity of 256 mOsm/kg, urine osmolarity of 648 mOsm/kg and urine sodium of 93 mEq/L. Adrenocorticotropic hormone (ACTH) stimulation test was within normal limits. Thyroid-stimulating hormone (TSH) was 88.6 IU/mL (0.380-4.700 IU/mL), total triiodothyronine (TT3) <21 ng/mL (0.8-2 ng/mL), free thyroxine (fT4) 0.10 ng/dL (0.93-1.70 ng/dL) and free triiodothyronine (fT3) <0.5 pg/mL (2.3-4.2 pg/mL). Antithyroid peroxidase antibody was 726 IU/mL (<9 IU/mL). TSH 1 year ago was 2.88 IU/mL and TT3 was 1.06 ng/mL. He was started on levothyroxine with improvement in his symptoms, sodium level and thyroid functions. The most likely culprit was pomalidomide. Checking thyroid functions before and periodically while on pomalidomide is important in screening for this possible side effect.

Abstract
BACKGROUND Relapsed/refractory (R/R) multiple myeloma (MM) patients and primary plasma cell leukemia (PCL) have an unfavorable prognosis and no effective treatment. This study was designed to assess the safety and preliminary efficacy of a novel anti-B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T cell in R/R MM and PCL. METHODS Between February 22, 2017, and June 25, 2018, 28 R/R and two R/R primary PCL patients received a median dose of 11.2 × 106 CAR+ cells/kg. The subjects were refractory to a proteasome inhibitor and/or an immunomodulatory agent. Fludarabine and cyclophosphamide were given as lymphodepletion chemotherapy. RESULTS Results for these 30 consecutive patients who received an anti-BCMA CAR T cell infusion are reported. The patients had received a median of four prior lines of therapy. A total of 44 different types of adverse events were recorded, and hematologic toxic effects were the most common events of any grade during treatment. Hematologic toxic effects were also the most common events of grade 3 or higher. A total of 29 patients (96.7%) had cytokine release syndrome, which was of grade 1 or 2 in 24 patients (80%) and grade 3 in five patients (16.7%). Neurologic toxic effects only occurred in one patient (3.3%) and were of grade 1. The objective response rate was 90%, and the complete response rate was 43.3%. With a median follow-up of 12.6 months, the median progression-free survival (PFS) and overall survival were 5.2 months and 14.0 months. One of the two primary PCL achieved a complete response with a PFS of 307 days. The other patients achieved a very good partial response with a PFS of 117 days. CONCLUSIONS Anti-BCMA CAR T cell treatment is safe and highly active in R/R multiple myeloma.

Abstract
PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class-refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class-refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class-refractory and extramedullary disease.

Abstract
Anti-platelet agents or anticoagulants are administered for patients with multiple myeloma (MM) receiving immunomodulatory drugs (IMiDs) to prevent thrombotic events (TEs). However, there is a discrepancy between current guidelines and clinical practice in thromboprophylaxis and the varied incidence of TEs depending on patient cohort. Therefore, a consensus on the optimal thromboprophylactic strategy is needed. To determine an appropriate strategy for the prevention of TEs in MM patients receiving IMiDs, we performed a retrospective single-institution analysis. In total, 95 MM patients (62% male, median age 65 years, range 30-85 years) from November 2008 to January 2018 were recruited, and 140 cases were analyzed in the medical-record-based study. Thromboprophylactic drugs were given to 69% of patients, anti-platelet agents to 66%, and anticoagulants to 3.0%. Seven TEs (5.0%) and six bleeding events (4.3%) were observed, but no patients died from thrombohemorrhage. The median follow-up period was 184 days (range 21-2224), and the cumulative TE incidence was 1.7% at 3 months, 7.0% at 1 year, and 12.5% at 3 years. Multivariate analysis determined that age > 70 years (p = 0.012) and BMI < 18.5 kg/m2 (p = 0.042) were the significant risk factors of TE. A low incidence of TEs was observed despite the low adherence to guideline recommendations for anticoagulant administration. These results suggest that anti-platelet agents are sufficient for thromboprophylaxis. A high-risk group of TEs in MM patients receiving IMiDs was identified, and a larger study is needed to confirm these findings.

Pomalidomide and dexamethasone combination with additional cyclophosphamide in relapsed/refractory multiple myeloma (AMN001)-a trial by the Asian Myeloma Network. Blood Cancer J 2019; 9:83. [PMID: 31594919 PMCID: PMC6783445 DOI: 10.1038/s41408-019-0245-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Revised: 09/17/2019] [Accepted: 09/19/2019] [Indexed: 11/23/2022] Open
Abstract
Pomalidomide is a third generation immunomodulatory drug which in combination with dexamethasone, has been shown to be active in relapsed/refractory multiple myeloma. However, the data in Asian patients remain limited. We conducted a prospective phase two clinical trial in major cancer centers in Singapore, South Korea, Taiwan, Japan and Hong Kong to assess the efficacy and safety of pomalidomide and dexamethasone combination (PomDex) +/− cyclophosphamide in Asian patients with relapsed/refractory multiple myeloma who failed lenalidomide and bortezomib. Patients were treated with pomalidomide (4 mg daily for 21 days every 4 weeks) and dexamethasone (40 mg weekly). If there is less than a minimal response after three cycles of PomDex, cyclophosphamide 300 mg/m2 can be added (PomCyDex). A total of 136 patients were enrolled. The median PFS was 9 and 10.8 months for the PomDex and PomCyDex group, respectively. The median OS was 16.3 months. This regimen appears to be active across age groups and prior lines of treatment. This combination was overall well tolerated with grade 3 and 4 adverse events of mainly cytopenias. PomDex is highly active and well-tolerated in Asian patients. The addition of cyclophosphamide can improve the response and outcomes further in patients with suboptimal response to PomDex.

Tolerability and safety of real-world use of pomalidomide in patients with relapsed/refractory multiple myeloma. Mol Clin Oncol 2018; 10:293-298. [PMID: 30680210 DOI: 10.3892/mco.2018.1775] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2018] [Accepted: 11/21/2018] [Indexed: 12/12/2022] Open
Abstract
Pomalidomide (POM) is a second-generation immunomodulatory agent with proven efficacy in patients with relapsed/refractory multiple myeloma (RRMM) proven to be refractory to previous treatment with lenalidomide (LEN) and bortezomib. We herein conducted a retrospective analysis of 14 RRMM patients receiving POM to determine its tolerability and safety in the clinical setting. The median age of the patients was 72 years (range, 58-84 years), and 85.7% of the patients were aged >70 years. The most frequent treatment dose was 3 mg/day. POM dose reductions were required in 54.5% (6/11) of the patients. The patient data were compared among three age groups (<70, 70-75 and >75 years) and there was only significant difference in daily POM treatment dose. The tolerability of POM must be confirmed, particularly in elderly patients. Dose reduction from 4 to 3 mg occurred during the second cycle in 83.3% (5/6) of the patients. It is important to determine the tolerability of POM in the early phases of treatment. The most frequently reported grade 3/4 hematological adverse events were neutropenia (64.3%), anemia (64.3%) and thrombocytopenia (57.1%). Although the median number of treatment cycles was 4 (range, 1-13), 21.4% (3/14) of the patients with a performance status (PS) of 3 were administered only 1 treatment cycle. The tolerability of POM was low among patients with poor PS and an aggressive treatment introduction should be avoided. However, 21.4% (3/14) of the patients were able to continue treatment for >1 year and some patients received long-term therapy. POM does not require dose modification for renal function, and multiple capsule doses are available, which is an advantage of POM compared with LEN. POM may be administered to late-stage RRMM patients in a real-world clinical setting, but elderly patients or those with poor PS must be treated with caution. In this manner, the treatment options for RRMM patients may be expanded by assessing the tolerability and safety of POM.

Abstract
Pomalidomide (Imnovid®; Pomalyst®), an analogue of thalidomide, is an immunomodulatory agent, with several mechanisms of action (both direct and indirect) thought to be involved in its anti-myeloma activity. Oral pomalidomide is available in several countries for use in combination with low-dose dexamethasone in adults with relapsed and refractory multiple myeloma. In multinational, phase II or III studies in patients with refractory, or relapsed and refractory multiple myeloma who had received ≥ 2 prior treatment regimens (including ≥ 2 cycles of both lenalidomide and bortezomib), pomalidomide plus low-dose dexamethasone was associated with prolonged progression-free survival (PFS) and overall survival and an improved overall response rate. Pomalidomide plus low-dose dexamethasone had a manageable tolerability profile, with neutropenia, infections, anaemia and thrombocytopenia being the most frequently reported grade 3 or 4 treatment-emergent adverse events. In conclusion, pomalidomide plus low-dose dexamethasone extends the treatment options available for the management of relapsed and refractory multiple myeloma in a patient population that has very limited treatment options.

Immunomodulatory drugs and the risk of serious infection in multiple myeloma: systematic review and meta-analysis of randomized and observational studies. Ann Hematol 2018; 97:925-944. [PMID: 29500711 DOI: 10.1007/s00277-018-3284-y] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2017] [Accepted: 02/25/2018] [Indexed: 01/11/2023]
Abstract
The effect of immunomodulatory drugs (IMiDs) on serious infection remains uncertain. We therefore conducted a systematic review and meta-analysis to assess the possible impact of IMiDs on serious infection in patients with multiple myeloma (MM). We searched randomized controlled trials (RCTs) and observational studies from databases that addressed the effect of IMiDs on serious infection in patients with MM. We pooled data from RCTs and observational studies separately and used the GRADE approach to rate the quality of evidence. Rates in patients with individual IMiDs at different treatment status ranged from 7.00 to 23.00%. The use of thalidomide- or lenalidomide-based regimen induction therapy for autologous stem cell transplantation (ASCT)-ineligible patients suggests increase in serious infection (RR = 1.59, 95% CI 1.31-1.93, p < 0.01). Compared to conventional therapy, IMiDs' induction in ASCT-eligible patients significantly decreases the risk of serious infection (RR = 0.82, 95% CI 0.72-0.94, p < 0.01). Lenalidomide-based therapy was associated with a significant increase in risk of serious infection in patients treated compared with conventional therapy (RR = 2.45, 95% CI 1.57-3.83, p < 0.01). The current evidence suggests that patients with MM treated with IMiDs are at a high risk of serious infection.
