A phase 2 clinical trial of luspatercept in non-transfusion-dependent patients with myelodysplastic syndromes.

Luspatercept has shown durable clinical efficacy for the treatment of anemia in transfusion-dependent patients with lower-risk myelodysplastic syndromes (LR-MDS). We report the results of a prespecified primary analysis of a phase 2 trial of luspatercept in non-transfusion-dependent (NTD) Japanese patients with anemia due to LR-MDS. Luspatercept (starting dose 1.

Safety of nivolumab monotherapy in five cancer types: pooled analysis of post-marketing surveillance in Japan.

Background: Nivolumab has been approved for treating ≥ 10 cancer types. However, there is limited information on the incidence of rare, but potentially serious, treatment-related adverse events (TRAEs), as well as notable TRAEs in patients with certain medical disorders or older patients in Japan.

Methods: We performed pooled analyses of data from published post-marketing surveillance in Japan of nivolumab monotherapy for patients with malignant melanoma, non-small cell lung cancer, renal cell carcinoma, head and neck cancer, and gastric cancer to determine the frequencies of 20 categories of TRAEs of special interest overall and in patient groups with higher perceived safety risks (history of autoimmune disease, interstitial lung disease, tuberculosis, or hepatitis B/C; patients vaccinated during nivolumab treatment; and older patients [≥ 75 years]).

Survival outcomes among patients with multiple myeloma in the era of novel agents: exploratory assessment using an electronic medical record database in Japan.

Despite recent advances in the range of therapies available for the treatment of multiple myeloma (MM), there are limited data surrounding survival outcomes and baseline characteristics influencing survival in general clinical practice in Japan. The aim of this study was to use electronic medical records (EMRs) to examine overall survival (OS) and prognostic factors in Japanese patients with MM. We extracted EMRs in the Real World Data (RWD) database of patients with a confirmed diagnosis of MM and treatment history with bortezomib, thalidomide, and/or lenalidomide.

Analysis of Japanese patients from the AUGMENT phase III study of lenalidomide + rituximab (R) vs. rituximab + placebo in relapsed/refractory indolent non-Hodgkin lymphoma.

Patients with indolent non-Hodgkin lymphoma (iNHL) typically respond to first-line immunochemotherapy, but relapse is common. Treatment options for relapsed iNHL include chemotherapy ± rituximab and rituximab monotherapy. Lenalidomide plus rituximab (R) is an immunomodulatory regimen that enhances rituximab-mediated cytotoxicity and improves clinical activity in iNHL.

[Lenalidomide and low-dose dexamethasone therapy for Japanese patients with newly diagnosed multiple myeloma: updated results of the MM-025 study].

In a Japanese phase II study (MM-025), the efficacy and safety of lenalidomide plus low-dose dexamethasone (Rd) were confirmed at a median follow-up of 14.2 months in patients with newly diagnosed multiple myeloma who were ineligible for hematopoietic stem cell transplantation. In the present report, we analyzed the follow-up data from the abovementioned study.

Multicenter Phase II Study of Lenalidomide in Relapsed or Recurrent Adult T-Cell Leukemia/Lymphoma: ATLL-002.

Purpose Few treatment options exist for adult T-cell leukemia/lymphoma (ATL), and the prognosis for this disease is poor. A phase I study of lenalidomide demonstrated preliminary antitumor activity in patients with relapsed ATL. The current phase II study evaluated the efficacy and safety of lenalidomide monotherapy in patients with relapsed or recurrent ATL.

Lenalidomide in relapsed adult T-cell leukaemia-lymphoma or peripheral T-cell lymphoma (ATLL-001): a phase 1, multicentre, dose-escalation study.

Background: Patients with adult T-cell leukaemia-lymphoma have few treatment options after relapse and poor survival outcomes with current therapies. We aimed to determine the maximum tolerated dose of lenalidomide, an oral immunomodulator, in Japanese patients with relapsed adult T-cell leukaemia-lymphoma and other peripheral T-cell lymphomas.

Methods: In this phase 1 study, we enrolled patients aged 20 years or older with Eastern Cooperative Oncology Group performance status 0-2, documented diagnosis of aggressive adult T-cell leukaemia-lymphoma or other peripheral T-cell lymphoma subtypes, and at least one previous antilymphoma therapy.

Lenalidomide and low-dose dexamethasone in Japanese patients with newly diagnosed multiple myeloma: A phase II study.

In the FIRST trial (MM-020), lenalidomide plus low-dose dexamethasone (Rd) reduced the risk of disease progression or death compared with combination melphalan-prednisone-thalidomide. As the FIRST trial did not include any Japanese patients, the efficacy and safety of continuous treatment with Rd was evaluated in 26 Japanese patients with newly diagnosed multiple myeloma (NDMM) in a single-arm, multicenter, open-label phase II trial (MM-025). Patients received lenalidomide on days 1-21 of each 28-day cycle, with a starting dose of 25 mg/day (dose adjusted for renal impairment), and 40 mg/day dexamethasone (dose adjusted for age) on days 1, 8, 15 and 22 of each 28-day cycle until disease progression or discontinuation for any reason.

Pomalidomide alone or in combination with dexamethasone in Japanese patients with refractory or relapsed and refractory multiple myeloma.

This phase 1, open-label, dose-escalation study investigated the tolerated dose (recommended dose), safety, efficacy, and pharmacokinetics of pomalidomide alone or pomalidomide plus low-dose dexamethasone in Japanese patients with refractory or relapsed and refractory multiple myeloma. Twelve patients were enrolled. Patients received pomalidomide 2 mg (Cohort 1) or 4 mg (Cohort 2) orally on day 1 and days 3-21 of a 28-day cycle.
