Real-world comparative effectiveness of triplets containing bortezomib (B), carfilzomib (C), daratumumab (D), or ixazomib (I) in relapsed/refractory multiple myeloma (RRMM) in the US.

Multiple available combinations of proteasome inhibitors, immunomodulators (IMIDs), and monoclonal antibodies are shifting the relapsed/refractory multiple myeloma (RRMM) treatment landscape. Lack of head-to-head trials of triplet regimens highlights the need for real-world (RW) evidence. We conducted an RW comparative effectiveness analysis of bortezomib (V), carfilzomib (K), ixazomib (I), and daratumumab (D) combined with either lenalidomide or pomalidomide plus dexamethasone (Rd or Pd) in RRMM.

Real-world outcomes and factors impacting treatment choice in relapsed and/or refractory multiple myeloma (RRMM): a comparison of VRd, KRd, and IRd.

Lack of head-to-head trials highlights a need for comparative real-world evidence of proteasome inhibitors plus Rd.: In this retrospective, US population-representative EHR study of RRMM patients initiating IRd, KRd, or VRd in line of therapy (LOT) ≥2 between 1/2014 and 9/30/2018, 664 patients were treated in LOT ≥2 with: IRd, n = 168; KRd, n = 208; VRd, n = 357. Median age was 71/65/71 years; 67%/70%/75% had a frailty score of intermediate/frail; 20%/28%/13% had high cytogenetic risk in I-/K-/V-Rd groups.

Realized and Projected Cost-Savings from the Introduction of Generic Imatinib Through Formulary Management in Patients with Chronic Myelogenous Leukemia.

Background: Imatinib, a first-generation tyrosine kinase inhibitor (TKI), and the newer second-generation TKIs have dramatically improved outcomes for patients with chronic myelogenous leukemia (CML). A previous model estimated the potential cost-savings over the next 2 years after the loss of patent exclusivity for imatinib in the United States in 2016 and its availability in a generic form. Payers have indeed realized meaningful savings, but it took 2 years for the prices of generic imatinib to decline substantially.

Randomized Clinical Trial Representativeness and Outcomes in Real-World Patients: Comparison of 6 Hallmark Randomized Clinical Trials of Relapsed/Refractory Multiple Myeloma.

Background: Concern has been increasing in oncology regarding randomized clinical trial (RCT) eligibility limiting the generalizability of the findings to real-world populations. Using a large US electronic health record database, we investigated the real-world generalizability of the findings from recent RCTs for relapsed and/or refractory multiple myeloma (RRMM).

Patients And Methods: Patients with RRMM initiating second-to fourth-line therapy with the control arm of the following RCTs were retrospectively identified and categorized as "RCT eligible" or "RCT ineligible" according to the eligibility criteria: (1) Rd (lenalidomide, dexamethasone)-ASPIRE, TOURMALINE-MM1, POLLUX, and ELOQUENT-2; and (2) Vd (bortezomib, dexamethasone)-CASTOR and ENDEAVOR.

Cost differential of immuno-oncology therapy delivered at community versus hospital clinics.

Objectives: The site of cancer care delivery has been shown to be associated with the total cost of care. The magnitude of this effect in patients receiving expensive immuno-oncology (I-O) therapies has not been evaluated. We evaluated cost differentials between community-based and hospital-based outpatient clinics among patients receiving I-O therapies.

A retrospective study evaluating treatment patterns and survival outcomes in elderly patients with acute myeloid leukemia treated in the United States with either 7+3 or a hypomethylating agent.

Intensive treatment for newly diagnosed acute myelogenous leukemia (ND-AML) patients are reserved for "fit" patients. While guidelines recommend evaluation of age, performance status and comorbidities, there is no consensus on the definition of "fitness" or optimal therapy for elderly AML patients. This retrospective study evaluated characteristics and survival outcomes of 274 patients (age ≥60 years) with ND-AML treated with 7 + 3 (cytarabine + an anthracycline) vs.

Adoption of triplet therapy and clinical outcomes in routine practice among newly diagnosed multiple myeloma patients not receiving frontline stem cell transplant in the USA.

Background: Immunomodulator (IMID) and proteasome inhibitor (PI) triplet frontline therapy (FT) in newly diagnosed multiple myeloma (NDMM) trials improve overall survival (OS); reported outcomes in routine practice are lacking. Authors compared outcomes in NDMM patients in the USA by use of triplet vs doublet FTs.

Methods: In this retrospective study of NDMM patients without FT transplant between 1/1/2008 and 6/30/2017, FT was categorized as: PI+IMID-triplet (≥ 3 drugs including PI+IMID), non-PI+IMID-triplet (≥ 3 drugs, not PI+IMID), doublet (≤ 2 drugs).

Cost Differences Associated With Oncology Care Delivered in a Community Setting Versus a Hospital Setting: A Matched-Claims Analysis of Patients With Breast, Colorectal, and Lung Cancers.

Purpose:: Access to high-quality cancer care remains a challenge for many patients. One such barrier is the increasing cost of treatment. With recent shifts in cancer care delivery from community-based to hospital-based clinics, we examined whether this shift could result in increased costs for patients with three common tumor types.

Economic Burden of Patients Treated for Higher-Risk Myelodysplastic Syndromes (HR-MDS) in Routine Clinical Care in the United States.

Background And Objective: Significant clinical burden is associated with higher-risk myelodysplastic syndromes (HR-MDS); however, the economic burden has not been fully examined. We examined cost of care and healthcare utilization (HCU) in HR-MDS patients engaged in routine care in the United States (US).

Methods: Adult US patients diagnosed with HR-MDS from 1/1/2008 to 10/31/2015 were identified from the Optum database.

Economic burden of elderly patients with acute myeloid leukemia treated in routine clinical care in the United States.

This retrospective claims database study examined healthcare utilization (HCU) and costs associated with acute myeloid leukemia (AML) in 237 elderly patients who received chemotherapy or a stem cell transplant (SCT) following AML diagnosis. Patients with secondary AML were excluded. Over the entire follow-up period, 92.

Transfusion-free interval is associated with improved survival in patients with higher-risk myelodysplastic syndromes engaged in routine care.

Most higher-risk myelodysplastic syndrome (HR-MDS) patients will become transfusion-dependent, leading to potential complications, including infections or end-organ dysfunction. Data correlating achievement of transfusion-free intervals (TFIs) during first-line therapy (1LT) with survival are sparse. We evaluated HR-MDS patients receiving 1LT diagnosed from 1/1/2008 to 7/31/2015 and the impact of a TFI (≥60-day interval without transfusions) on progression-free and overall survival (PFS, OS) using Cox proportional-hazard models.

Prolonged Duration of Therapy Is Associated With Improved Survival in Patients Treated for Relapsed/Refractory Multiple Myeloma in Routine Clinical Care in the United States.

Background: In clinical trials, an extended therapy duration has been associated with better outcomes in patients with newly diagnosed multiple myeloma (NDMM). However, data on how the therapy duration affects the outcomes for patients with relapsed/refractory multiple myeloma (RRMM) are limited. We conducted a large, retrospective study in the United States to evaluate the effect of the duration of second-line therapy on overall survival.

The impact of age and comorbidities on practice patterns and outcomes in patients with relapsed/refractory multiple myeloma in the era of novel therapies.

Objectives: One-third of patients with multiple myeloma (MM) are diagnosed at age≥75years. Older patients have increased incidence of cardiovascular disease (CVD) and renal insufficiency (RI), hallmark complications of MM. We examined cumulative incidence of CVD and RI in relapsed/refractory MM (RRMM) and outcomes by age and RI/CVD.

A modified regimen of biweekly gemcitabine and nab-paclitaxel in patients with metastatic pancreatic cancer is both tolerable and effective: a retrospective analysis.

Background: Treatment with nab-paclitaxel with gemcitabine demonstrates a survival advantage when compared with single-agent gemcitabine. However, the combination is associated with significant toxicities, leading to a high rate of drug discontinuation. We implemented a modified regimen of gemcitabine and nab-paclitaxel (mGNabP) in an attempt to minimize toxicities while maintaining efficacy.

Unintended Consequences in Cancer Care Delivery Created by the Medicare Part B Proposal: Is the Clinical Rationale for the Experiment Flawed?

Purpose: Medicare currently enrolls ≥ 45 million adults, and by 2030 this is projected to increase to ≥ 80 million beneficiaries. With this growth, the Centers for Medicare & Medicaid Services (CMS) issued a proposal, the Medicare Part B Drug Payment Model, to shrink drug expenditures, a major contributor to overall health care costs. For this to not adversely affect patient outcomes, lower-cost alternative medications with equivalent efficacy and no increased toxicity must be available.

Biweekly gemcitabine and low-dose cisplatin in the treatment of locally advanced or metastatic pancreatic cancer patients: a single institute experience.

Gemcitabine in combination with low-dose cisplatin has shown promising activity in pancreatic cancer with manageable toxicities. The purpose of this study is to assess the activity of a combination of gemcitabine and low-dose cisplatin in the first-line treatment of metastatic and locally advanced pancreatic cancer patients. We conducted a retrospective analysis of all patients diagnosed with metastatic and locally advanced pancreatic cancer who received a combination of gemcitabine and cisplatin in the first-line setting.

Neoadjuvant modified (m) FOLFIRINOX for locally advanced unresectable (LAPC) and borderline resectable (BRPC) adenocarcinoma of the pancreas.

Background: For patients with metastatic pancreatic cancer, FOLFIRINOX (fluorouracil [5-FU], leucovorin [LV], irinotecan [IRI], and oxaliplatin) has shown improved survival rates compared with gemcitabine but with significant toxicity, particularly in patients with a high tumor burden. Because of reported response rates exceeding 30 %, the authors began to use a modified (m) FOLFIRINOX regimen for patients with advanced nonmetastatic disease aimed at downstaging for resection. This report describes their experience with mFOLFIRINOX and aggressive surgical resection.

Palonosetron for the prevention of chemotherapy-induced nausea and vomiting.

Chemotherapy-induced nausea and vomiting (CINV) remains both a feared side effect of cancer treatment and a focus of many supportive care initiatives/guidelines. The class of medications known as serotonin receptor antagonists (5-HT3RAs) are integral in the prevention of CINV from both moderately and highly emetogenic chemotherapy. Palonosetron (ALOXI(®)), a second-generation 5-HT3RA, has a higher affinity for the 5-HT3 receptor, has a longer half-life and has unique interactions with the 5-HT3 receptor compared with the current first-generation 5-HT3RA such as ondansetron, granisetron, dolasetron and tropisetron.

Pilot study on the efficacy of an ondansetron- versus palonosetron-containing antiemetic regimen prior to highly emetogenic chemotherapy.

Purpose: Nausea and vomiting are among the most feared complications of chemotherapy reported by patients. The objective of this study was to establish the overall complete response (CR; no emesis or use of rescue medication 0-120 h after chemotherapy) with either ondansetron- or palonosetron-containing antiemetic regimens in patients receiving highly emetogenic chemotherapy (HEC).

Methods: This was a prospective, open-label, randomized, single-center, pilot study that enrolled patients receiving their first cycle of HEC.

Antiemetic control with palonosetron in patients with gastrointestinal cancer receiving a fluoropyrimidine-based regimen in addition to either irinotecan or oxaliplatin: a retrospective study.

Background: For moderately emetogenic chemotherapy, palonosetron (PALO) is reported to provide complete control of chemotherapy-induced nausea and vomiting (CINV) in 69% of patients. Prior to August 2009, our gastrointestinal (GI) cancer patients receiving the moderately emetogenic compounds oxaliplatin or irinotecan plus a fluoropyrimidine regimen received ondansetron and dexamethasone orally on day 1 of chemotherapy for CINV prevention. Beginning in August of 2009, ondansetron was replaced by PALO 0.

Yttrium-90 radioembolization as salvage therapy for colorectal cancer with liver metastases.

Background: Few patients with metastatic colorectal cancer (mCRC) are candidates for resection of their hepatic disease. Yttrium-90 ((90)Y) radioembolization has promise in the treatment of unresectable mCRC. We conducted a retrospective study to assess the efficacy in patients with refractory mCRC who underwent (90)Y radioembolization.
