Health-related quality of life in GALAHAD: A multicenter, open-label, phase 2 study of niraparib for patients with metastatic castration-resistant prostate cancer and DNA-repair gene defects.

Niraparib is a highly selective poly (adenosine diphosphateribose) polymerase-1 and poly (adenosine diphosphate-ribose) polymerase-2 inhibitor indicated for select patients with ovarian, fallopian tube, and primary peritoneal cancer. The phase 2 GALAHAD trial (NCT02854436) demonstrated that niraparib monotherapy is tolerable and efficacious in patients with metastatic castration-resistant prostate cancer (mCRPC) and homologous recombination repair (HRR) gene alterations, particularly those with breast cancer gene () alterations who had progressed on prior androgen signaling inhibitor therapy and taxane-based chemotherapy. To report the prespecified patient-reported outcomes analysis from GALAHAD.

Niraparib in patients with metastatic castration-resistant prostate cancer and DNA repair gene defects (GALAHAD): a multicentre, open-label, phase 2 trial.

Background: Metastatic castration-resistant prostate cancers are enriched for DNA repair gene defects (DRDs) that can be susceptible to synthetic lethality through inhibition of PARP proteins. We evaluated the anti-tumour activity and safety of the PARP inhibitor niraparib in patients with metastatic castration-resistant prostate cancers and DRDs who progressed on previous treatment with an androgen signalling inhibitor and a taxane.

Methods: In this multicentre, open-label, single-arm, phase 2 study, patients aged at least 18 years with histologically confirmed metastatic castration-resistant prostate cancer (mixed histology accepted, with the exception of the small cell pure phenotype) and DRDs (assessed in blood, tumour tissue, or saliva), with progression on a previous next-generation androgen signalling inhibitor and a taxane per Response Evaluation Criteria in Solid Tumors 1.

Niraparib with androgen receptor-axis-targeted therapy in patients with metastatic castration-resistant prostate cancer: safety and pharmacokinetic results from a phase 1b study (BEDIVERE).

Purpose: To assess the safety and pharmacokinetics and determine the recommended phase 2 dose (RP2D) of niraparib with apalutamide or abiraterone acetate plus prednisone (AAP) in patients with metastatic castration-resistant prostate cancer (mCRPC).

Methods: BEDIVERE was a multicenter, open-label, phase 1b study of niraparib 200 or 300 mg/day with apalutamide 240 mg or AAP (abiraterone acetate 1000 mg; prednisone 10 mg). Patients with mCRPC were previously treated with ≥ 2 lines of systemic therapy, including ≥ 1 androgen receptor-axis-targeted therapy for prostate cancer.

Efficacy and safety of apalutamide in Japanese patients with nonmetastatic castration-resistant prostate cancer: a subgroup analysis of a randomized, double-blind, placebo-controlled, Phase-3 study.

Background: In the global Phase-3 Selective Prostate Androgen Receptor Targeting with ARN-509 study, apalutamide plus ongoing androgen deprivation therapy (ADT) significantly increased metastasis-free survival (MFS) and improved other clinical outcomes in men with nonmetastatic castration-resistant prostate cancer (nm-CRPC) who were at high risk of developing metastases. In this subpopulation analysis of Selective Prostate Androgen Receptor Targeting with ARN-509 study, the efficacy and safety of apalutamide plus ADT were evaluated in Japanese patients with nm-CRPC.

Methods: The primary efficacy end point was MFS.

Understanding symptomatic experience, impact, and emotional response in recently diagnosed metastatic castration-resistant prostate cancer: a qualitative study.

Purpose: We sought to explore the symptomatic experience of men recently told their castration-resistant prostate cancer has metastasized (mCRPC); the impact and emotional response to this; the emotional burden of monitoring development to metastatic status; and the emotional impact on the primary support person (PSP).

Methods: Interviews were conducted with 25 men recently diagnosed with mCRPC from the United States (US), France, and Germany. We also interviewed 14 PSPs.

Apalutamide Treatment and Metastasis-free Survival in Prostate Cancer.

Background: Apalutamide, a competitive inhibitor of the androgen receptor, is under development for the treatment of prostate cancer. We evaluated the efficacy of apalutamide in men with nonmetastatic castration-resistant prostate cancer who were at high risk for the development of metastasis.

Methods: We conducted a double-blind, placebo-controlled, phase 3 trial involving men with nonmetastatic castration-resistant prostate cancer and a prostate-specific antigen doubling time of 10 months or less.

Phase I/II trial of nonpegylated liposomal doxorubicin, cyclophosphamide, vincristine, and prednisone in the treatment of newly diagnosed aggressive non-Hodgkin's lymphoma.

Background: The toxicity and efficacy of nonpegylated liposomal doxorubicin (TLC D-99) when substituted for conventional doxorubicin in the CHOP (doxorubicin/cyclophosphamide/vincristine/prednisone) regimen were evaluated in the treatment of newly diagnosed patients with aggressive non-Hodgkin's lymphoma. Liposomal doxorubicin at doses of 40 mg/m2, 50 mg/m2, 60 mg/m2, and 80 mg/m2 was given with fixed doses of cyclophosphamide, vincristine, and prednisone. Chemotherapy cycles were repeated every 21 days.

Phase I study of antisense oligonucleotide against vascular endothelial growth factor: decrease in plasma vascular endothelial growth factor with potential clinical efficacy.

Purpose: Vascular endothelial growth factor antisense (VEGF-AS) is an antisense oligonucleotide that targets VEGF, inhibiting angiogenesis and tumor cell proliferation. This study established the safety, biologic effects, and pharmacokinetics of VEGF-AS in 51 patients with advanced malignancies.

Methods: VEGF-AS was administered as a 2-hour infusion daily for 5 consecutive days for only one cycle on the first four dose levels, and then administered daily for 5 days every other week for up to 4 months on subsequent levels.

Hepatitis C virus-related thrombocytopenia: clinical and laboratory characteristics compared with chronic immune thrombocytopenic purpura.

Thrombocytopenia can be a complication of hepatitis C viral (HCV) infection. However, there is little published data regarding the clinical and laboratory manifestations of HCV-related thrombocytopenia (HCV-TP) compared with adult chronic immune thrombocytopenic purpura (CITP). We reviewed the medical records for all patients evaluated for chronic thrombocytopenia by the Haematology Service between January 1996 and June 2000.

AIDS-related Burkitt's lymphoma versus diffuse large-cell lymphoma in the pre-highly active antiretroviral therapy (HAART) and HAART eras: significant differences in survival with standard chemotherapy.

Purpose: To compare outcomes of patients with HIV-Burkitt's lymphoma (HIV-BL) and HIV-diffuse large-cell lymphoma (HIV-DLCL) after treatment with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) or M-BACOD (methotrexate, bleomycin, cyclophosphamide, etoposide) in pre-highly active antiretroviral therapy (HAART) versus HAART eras.

Patients And Methods: Three hundred sixty-three patients with AIDS-related lymphoma diagnosed from 1982 to 2003 were reviewed retrospectively, including 262 in the pre-HAART (HIV-BL, 117; HIV-DLCL, 145) and 101 in the HAART era (HIV-BL, 18; HIV-DLCL, 83). Pre-HAART included those who did not receive HAART, and HAART era included those diagnosed after January 1997 who received HAART.

Weekly docetaxel is safe and effective in the treatment of advanced-stage acquired immunodeficiency syndrome-related Kaposi sarcoma.

Background: Intravenous paclitaxel, 100 mg/m(2), given over 3 hours every 2 weeks is associated with a response rate of 59% in patients with recurrent or refractory acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma (KS). However, this regimen is associated with significant myelosuppression, and the inconvenience of a 3-hour infusion. Moreover, no effective therapies have been defined for use after treatment failure with this agent.

T-cell lymphoma in HIV-infected patients.

Linkage of AIDS and cancer registries has indicated an increase in T-cell lymphomas among individuals infected with the HIV. The characteristics of T-cell versus B-cell lymphoma in HIV-infected patients are not well described. Retrospectively, 11 cases of T-cell lymphoma were identified from the AIDS-Lymphoma Registry at the University of Southern California.

Liposome-encapsulated doxorubicin in combination with standard agents (cyclophosphamide, vincristine, prednisone) in patients with newly diagnosed AIDS-related non-Hodgkin's lymphoma: results of therapy and correlates of response.

Purpose: To evaluate the safety and efficacy of liposomal doxorubicin (Myocet; Medeus Pharma Ltd, Herts,UK) when substituted for doxorubicin in the CHOP regimen (cyclophosphamide, doxorubicin, vincristine, prednisone) in patients with newly diagnosed AIDS-related non-Hodgkin's lymphoma (AIDS-NHL). Secondary objectives were to assess the impact of HIV viral control on response and survival, and to correlate MDR-1 expression with outcome.

Patients And Methods: Liposomal doxorubicin at doses of 40, 50, 60, and 80 mg/m(2) was given with fixed doses of cyclophosphamide, vincristine, and prednisone every 21 days.

Purpose: To evaluate the response and side effects of combination therapy with low dose CHOP chemotherapy and mitoguazone dihydrochloride in patients with non-Hodgkin's lymphoma associated with the acquired immunodeficiency syndrome (AIDS-NHL).

Methods: Eighteen patients newly diagnosed with intermediate or high-grade AIDS-NHL were treated with low dose CHOP as follows: day 1, cyclophosphamide 350 mg/m(2), intravenously (IV); doxorubicin 25mg/m(2) IV; vincristine 2mg IV; and prednisone 100mg given orally on days 1 through 5. In addition, mitoguazone dihydrochloride was given at a dose of 600 mg/m(2) IV on days 1 and 15 of each 28-day treatment cycle.

Potential role of platelet FcgammaRIIA in collagen-mediated platelet activation associated with atherothrombosis.

Collagen-mediated platelet activation contributes significantly to coronary and cerebrovascular thrombus formation associated with atherosclerotic plaque destabilization. Recent clinical and laboratory observations support a potential role for the platelet Fc receptor (FcgammaRIIA) in this process. The purpose of this study was to elucidate any association between platelet Fc receptor (FcR) expression levels and both atherosclerosis risk factors (ARFs) along with collagen-dependent platelet activation.

Detection of lupus anticoagulant identifies patients with autoimmune haemolytic anaemia at increased risk for venous thromboembolism.

Venous thromboembolism (VTE) is a well-recognized complication of autoimmune haemolytic anaemia (AIHA), and is a major cause of morbidity and mortality in this disorder. However, the incidence, pathogenesis and risk-factors for VTE in AIHA remain poorly defined. Lupus anticoagulants (LA) and anticardiolipin (ACA) antibodies are autoantibodies directed against epitopes on prothrombin or beta2 glycoprotein I (beta2-GPI).

Multicenter trial of low-dose paclitaxel in patients with advanced AIDS-related Kaposi sarcoma.

Background: Treatment options are limited for patients with advanced acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma (AIDS-KS) whose disease has progressed after receiving therapy with liposomal anthracyclines or combination chemotherapy with doxorubicin (Adriamycin), bleomycin, and vincristine (ABV). This study was performed to assess the safety and efficacy of a novel dose and schedule of paclitaxel in patients with AIDS-KS who failed to respond to previous systemic chemotherapy.

Methods: This was an open-label, multicenter Phase II study.

Characteristics of indolent non-Hodgkin lymphoma in patients with type 1 human immunodeficiency virus infection.

Background: There is recent evidence that the incidence of indolent non-Hodgkin lymphoma (NHL) appears to be increased in persons with the acquired immunodeficiency syndrome (AIDS). The current study was conducted to describe the clinical, immunologic, and pathologic characteristics of indolent B-cell lymphoma in patients infected with the human immunodeficiency virus (HIV).

Methods: The current report was a retrospective study of 10 cases of indolent NHL identified from the AIDS-Lymphoma Registry at the University of Southern California School of Medicine.

Multidrug resistance (MDR-1) expression in AIDS-related lymphomas.

P-glycoprotein is a product of the multidrug resistance (MDR-1) gene. In non-Hodgkin's lymphoma, less than 20% of untreated de novo lymphomas express MDR-1 compared with approximately 50% after failure of chemotherapy. We wished to study the expression of MDR-1 in AIDS-related non-Hodgkin's lymphoma (AIDS-NHL).
