RESUMO

Relationships between patient characteristics, ofatumumab pharmacokinetics, and treatment outcomes were investigated in this phase 2 trial of ofatumumab plus fludarabine and cyclophosphamide (FC) in untreated chronic lymphocytic leukemia. Patients were randomized 1:1 to receive 500 or 1000 mg ofatumumab (Cycle 1; 300 mg) plus FC every 4 weeks for six cycles. Median Cmax and Ctrough values were similar at Cycle 1 regardless of the ultimate clinical outcome. At later doses, these values were higher for patients with complete response (CR) than for other patients. Higher Cmax and Ctrough values at Cycles 3 and 6 were significantly associated with an increased likelihood of CR, whereas ofatumumab pharmacokinetics were not associated with an objective response (OR) on the basis of univariate analyses. Multivariate analyses indicated that baseline patient/disease factors were predominantly associated with CR (17p status) or OR (bulky lymphadenopathy, gender, and serum thymidine kinase), rather than ofatumumab pharmacokinetics.

RESUMO

This international, multicentre phase II study was conducted to assess ofatumumab, a human anti-CD20 monoclonal antibody, in patients with relapsed/progressive diffuse large B-cell lymphoma (DLBCL) who were ineligible for autologous stem cell transplantation (TI) or who had relapse/progression after transplantation (PT). Eighty-one patients received ofatumumab 300 mg intravenously (IV) on Day 1, followed by seven weekly IV infusions of 1000 mg. Patients in the TI and PT groups had received a median of 3 (range, 1-7) and 5 (range, 2-7) prior therapies, respectively. One-third of patients did not respond to the last prior therapy, and 53% had failed two or more rituximab-containing therapies. Overall response rate was 13% for the TI group (seven partial responses) and 8% for the PT group (two complete responses). Median progression-free survival was 2·6 months, and median duration of response was 9·5 months. The most common Grade 3-4 adverse events were neutropenia (11%), leucopenia (6%), lymphopenia (6%) and thrombocytopenia (6%). Sixteen deaths have been reported, with disease progression as the most common cause of death. In conclusion, ofatumumab monotherapy was well tolerated and provided clinical benefit to some DLBCL patients in this study.

RESUMO

PURPOSE/OBJECTIVES: To (a) examine coping capacity, psychological distress, spiritual well-being, positive and negative religious coping, and coping strategies among African American (AA) women with breast cancer, and (b) explore relationships among these variables to enhance an already tested comprehensive coping strategy program (CCSP) intervention for AA women with breast cancer (CCSP-AA). DESIGN: Descriptive-correlational. SETTING: Comprehensive cancer center in Maryland. SAMPLE: 17 AA women with breast cancer. METHODS: Women completed the Hospital Anxiety and Depression Scale, Sense of Coherence scale, Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being, Brief Religious Coping Inventory, and Coping Strategies Questionnaire. MAIN RESEARCH VARIABLES: Psychological distress, coping capacity, coping strategies, religious coping, and spiritual well-being. FINDINGS: A higher coping capacity was beneficial, as it was related to less psychological distress, negative religious coping, and catastrophizing. Women using less negative religious coping had greater spiritual well-being and less distress. Using more coping self-statements was associated with higher spiritual well-being and less negative religious coping. Catastrophizing had a negative effect on psychological distress and spiritual well-being. CONCLUSIONS: The development of a CCSP-AA that incorporates aspects of spirituality and components in a coping intervention needs to be tested in a clinical trial. The intervention will teach patients to recognize and restructure their thinking to avoid catastrophizing and negative religious coping. IMPLICATIONS FOR NURSING: Nurses need to work collaboratively with AA women to reinforce beneficial coping patterns and approaches. A tailored CCSP-AA for women with breast cancer administered by a nurse can be taught to assist AA patients in coping more effectively. KNOWLEDGE TRANSLATION: AA women with breast cancer use more positive religious coping and experience less distress and greater spiritual well-being, but catastrophizing has a negative effect on spiritual well-being. Nurses need to reinforce positive coping patterns for AA women with cancer.

RESUMO

BACKGROUND: This study aims to examine the effectiveness of a self-management multimodal comprehensive coping strategy program (CCSP) on quality of life (QOL) among breast cancer patients 1 year after treatment. METHODS: Patients (n = 110) with stage II, III, or IV breast cancer scheduled to receive high dose chemotherapy and autologous hematopoietic stem cell transplantation were randomized to either CCSP treatment or control group. The CCSP intervention was taught 2 week before hospital admission with reinforcement at specified times during treatment and 3 months after discharge. The CCSP components included educational information, cognitive restructuring, coping skills enhancement, and relaxation with guided imagery. Instruments administered at baseline included the following: Quality of Life Index-Cancer Version (QOLI-CV), State-Trait Anxiety Inventory, Beck Depression Inventory, and Coping Strategies Questionnaire. At 1-year follow-up, patients (n = 73) completed and returned the follow-up QOLI-CV. RESULTS: Patients were mainly ≥ 40 years of age, married, Caucasian, and diagnosed with advanced breast cancer. A model measuring effectiveness of CCSP on QOL (total and subscale) at 1-year follow-up showed that the CCSP group (n = 38) had significant improvement in overall QOL (p < 0.01), health and functioning (p < 0.05), and socioeconomic (p < 0.05) and psychological/spiritual well-being (p < 0.01) compared with the control group (n = 35). The CCSP patients frequently used the CCSP to manage psychological (51%) and sleep problems (60%). CONCLUSIONS: The CCSP improved QOL for patients at 1-year follow-up. Patients overwhelmingly reported that CCSP was beneficial. The CCSP as an effective coping intervention has potential as a self-management program for breast cancer survivors.

RESUMO

New treatments are required for rituximab-refractory follicular lymphoma (FL). In the present study, patients with rituximab-refractory FL received 8 weekly infusions of ofatumumab (CD20 mAb; dose 1, 300 mg and doses 2-8, 500 or 1000 mg; N = 116). The median age of these patients was 61 years, 47% had high-risk Follicular Lymphoma International Prognostic Index scores, 65% were chemotherapy-refractory, and the median number of prior therapies was 4. The overall response rate was 13% and 10% for the 500-mg and 1000-mg arms, respectively. Among 27 patients refractory to rituximab monotherapy, the overall response rate was 22%. The median progression-free survival was 5.8 months. Forty-six percent of patients demonstrated tumor reduction 3 months after therapy initiation, and the median progression-free survival for these patients was 9.1 months. The most common adverse events included infections, rash, urticaria, fatigue, and pruritus. Three patients experienced grade 3 infusion-related reactions, none of which were considered serious events. Grade 3-4 neutropenia, leukopenia, anemia, and thrombocytopenia occurred in a subset of patients. Ofatumumab was well tolerated and modestly active in this heavily pretreated, rituximab-refractory population and is therefore now being studied in less refractory FL and in combination with other agents in various B-cell neoplasms. The present study was registered at www.clinicaltrials.gov as NCT00394836.

RESUMO

An international, Phase II trial was conducted to assess two doses of ofatumumab, a human CD20 monoclonal antibody, combined with cyclophosphamide (750 mg/m(2) ), doxorubicin (50 mg/m(2) ), prednisone (100 mg days 3-7) and vincristine (1·4 mg/m(2) ) (O-CHOP), as frontline treatment for follicular lymphoma (FL). 59 patients with previously untreated FL were randomized to ofatumumab 500 mg (n = 29) or 1000 mg (n = 30) day 1, with CHOP on day 3 every 3 weeks for six cycles. Median duration of FL was 0·1 years for both dose groups; 34% and 38% of patients had high-risk Follicular Lymphoma International Prognostic Index (FLIPI) scores in the 500- and 1000-mg dose groups, respectively. Overall response rate was 90% for the 500-mg group and 100% for the 1000-mg group. 62% of patients achieved complete response (CR)/unconfirmed CR (CRu). 76% of patients with FLIPI score 3-5 attained CR/CRu. Longer follow-up time is needed for analysis of survival end points. The most common Common Terminology Criteria grade 3-4 investigator-reported adverse events were leucopenia (29%) and neutropenia (22%). No deaths have been reported. O-CHOP was safe and efficacious in patients with previously untreated FL, including high-risk FLIPI groups. This trial was registered at www.clinicaltrials.gov (NCT00494780).
