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.

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.
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.
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.
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.

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.
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.

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.

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.

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.
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.

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.
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).
