RESUMO

OBJECTIVE: To evaluate the current literature for tisagenlecleucel in the treatment of relapsed/refractory (r/r) B-cell acute lymphoblastic leukemia (ALL). DATA SOURCES: A literature search of PubMed (inception to June 18, 2020) and ClinicalTrials.gov was conducted using the following search terms: CTL019, chimeric antigen receptor, CAR-T, and tisagenlecleucel. STUDY SELECTION AND DATA EXTRACTION: All trials evaluating the use of tisagenlecleucel in B-cell ALL were reviewed and considered for inclusion. DATA SYNTHESIS: Tisagenlecleucel displayed overall remission rates ranging from 69% to 93% in patients who historically respond extremely poorly to salvage therapy. Remissions were durable, with 12-month relapse-free survival (RFS) rates of 55% to 59%. These promising results are tempered by the unique adverse effect profile of chimeric antigen receptor (CAR) T-cell therapy. Potentially life-threatening cytokine release syndrome (CRS) occurred in 77% to 100% of patients, and immune effector cell-associated neurotoxicity syndrome (ICANS) developed in 31% to 45% of patients receiving tisagenlecleucel. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: The successful utilization of tisagenlecleucel therapy requires meticulous planning, prudent patient selection, multidisciplinary collaboration, and expert training to ensure optimal patient care. The complex interplay of patient- and treatment-related factors creates problematic barriers that must be expertly navigated by the health care team and authorized treatment center. CONCLUSIONS: As the first US Food and Drug Administration-approved gene therapy, tisagenlecleucel heralds an immunotherapeutic breakthrough for treating pediatric and young adult patients with r/r B-cell ALL. Many questions surrounding patient-specific gene and cellular therapies remain, but their transformative potential in cancer care remains promising.

RESUMO

OBJECTIVE: To evaluate the literature for axicabtagene ciloleucel (axi-cel), a first-in-class chimeric antigen receptor (CAR) T-cell therapy, in the treatment of relapsed/refractory (r/r) large B-cell lymphoma (LBCL). DATA SOURCES: We conducted a PubMed (inception to June 22, 2020) and ClinicalTrials.gov search using the following terms: CD19, chimeric antigen receptor, and lymphoma. STUDY SELECTION AND DATA EXTRACTION: All retrospective and prospective studies evaluating the use of axi-cel in LBCL were reviewed. DATA SYNTHESIS: In the pivotal ZUMA-1 trial, axi-cel exhibited unprecedented overall and complete response rates of 83% and 58%, respectively. With a median follow-up of 27.1 months, 39% of patients had ongoing responses. Furthermore, postmarketing retrospective analyses found similar response rates in a more clinically diverse LBCL patient population. Novel CAR T-cell therapy elicits unique and potentially life-threatening toxicities that include cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Studies reported grade ≥3 CRS in 7% to 14% of patients and grade ≥3 ICANS in 31% to 55% of patients. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Axi-cel was the first US Food and Drug Administration-approved genetically engineered autologous CAR T-cell agent in r/r LBCL, representing an important milestone and paradigm shift in cancer treatment. Adoptive T-cell immunotherapy is a breakthrough treatment modality requiring careful patient selection, multidisciplinary collaboration, comprehensive patient counseling, and expert training to ensure optimal treatment. CONCLUSIONS: The initial and ongoing results with axi-cel are encouraging, but long-term safety and efficacy data are lacking. Additional studies are required to identify axi-cel's ideal place in LBCL therapy.

RESUMO

Despite advances in diagnosis and treatment options, breast cancer is one of the main causes of cancer related death among women worldwide. Present study is aimed to preliminarily evaluate our hypothesis that the combination of resveratrol (RSV), a natural antioxidant, and lower dose of sorafenib (SF), a multi-kinase inhibitor and a component of ERK1/2 (extracellular signal-regulated kinase 1/2) pathway, would augment apoptosis in human breast cancer MCF7 cells. MCF7 cellexpressions s were treated with RSV, SF and their combination. MTT (3-[4,5-dimethylthiazol-2-yl] -2, 5-diphenyl-tetrazolium bromide) assay, DNA fragmentation assay, Hoechst33342, H2DCFDA (2', 7'-Dichlorodihydrofluorescein diacetate), Rhodamine123 staining, and Western Blot to detect different signaling protein expressions, were conducted to test the hypothesis. Combination of RSV and SF showed higher cytotoxicity on MCF7 cells than their individual treatment. Results from morphology change, Hoechst33342 staining, and DNA fragmentation suggested higher apoptosis data in the combinational treatment. Intracellular ROS (reactive oxygen species) levels, p53 and Bax/Bcl2 expressions, and decrease in mitochondrial membrane potential were also higher in the combinational treatment. Up-regulation of apaf-1, cl. caspase 9, cl. caspase 3 and cl. PARP (poly (ADP-Ribose) polymerase) were also noticed, while the expressions of cyclinD1 and cyclinB1 were decreased in the combinational group. The increase in apoptosis and signaling protein expressions with RSV and SF combinational treatment were increased over time. The combination of RSV and lower dose of SF at 6µM showed enhanced apoptotic activity than SF alone. Therefore, RSV can be considered as a neo-adjuvant to improve SF efficacy in breast cancer treatment.

RESUMO

Although cancer metastases are known to be the main cause of cancer-related deaths, truly effective antimetastatic therapeutics remain scarce in clinical practice. Naturally occurring polyphenols are the most abundant antioxidants in human diets. Many of them possess chemopreventive and chemotherapeutic properties against various types of cancer. Recent advances in understanding the molecular pathways that mediate cancer development and progression have led to an increase of interest in preclinical investigations on the mechanisms underlying anticancer activity of polyphenols. In particular, an increasing number of preclinical studies using cultured cells and animal models have demonstrated the inhibitory effects of polyphenols on tumour cell invasion and metastasis, thereby highlighting the potential of polyphenols against metastatic cancer. This review specifically addresses growing evidence of the capability of polyphenols to impair the invasion and migration of tumour cells through a diverse set of mechanisms, including downregulation of expression of matrix metalloproteinases, modulation of regulators of epithelial-mesenchymal transition, interference with Met signalling, inhibition of nuclear factor-kappa B mediated transcription, and so on. Given that metastasis occurs through a multistep process in which each step is regulated by a complex network of signalling pathways, the multi-function and multi-target characteristics of polyphenols render those promising candidates for effective adjuvant therapy against metastatic cancer.

RESUMO

The purpose of this article is to review eliglustat tartrate, a substrate reduction therapy, for the treatment of Gaucher disease type 1 (GD1). GD is an rare inborn error of metabolism caused by accumulation of lipid substrates such as glucosylceramide within the monocyte-macrophage system that affects the body by causing enlargement of the spleen and liver, destruction of bone, and abnormalities of the lungs and blood, such as anemia, thrombocytopenia, and leukopenia. GD is classified into three types: GD1, a chronic and non-neuronopathic disease accounting for 95% of GD cases; and types 2 and 3 (GD2 GD3) which are more progressive diseases with no approved drugs available at this time. Treatment options for GD1 include enzyme replacement therapy and substrate reduction therapy. Eliglustat works by inhibiting UDP-glucosylceramide synthase, the first enzyme that catalyzes the biosynthesis of glycosphingolipids, thus reducing the load of glucosylceramide influx into the lysosome. Eliglustat was approved by the US Food and Drug Administration after three Phase I, two Phase II, and two Phase III clinical trials. The dose of eliglustat is 84 mg twice a day or once daily depending on the cytochrome P450 2D6 genotype of the patient.

RESUMO

OBJECTIVE: To review the pharmacology and pharmacokinetics, and to evaluate the clinical efficacy, safety, and place in therapy of enzalutamide for the treatment of castration-resistant prostate cancer (CRPC). DATA SOURCES: A literature search through PubMed (1984 to November 2013; English language) was performed using the following keywords: MDV3100, androgen deprivation therapy, enzalutamide, CRPC, and androgen receptor antagonist. Searches were limited to published studies in humans. STUDY SELECTION AND DATA EXTRACTION: All articles in English identified from reviews, abstracts, presentations, and clinical trials of enzalutamide in humans were selected and included. DATA SYNTHESIS: Enzalutamide is an oral, nonsteroidal second-generation androgen receptor antagonist that is Food and Drug Administration-approved for the treatment of metastatic CRPC in men who were previously treated with docetaxel. Enzalutamide was superior to placebo for increasing median survival from 13.6 months to 18.4 months. Enzalutamide was well tolerated at a dose of 160 mg, with minor adverse events such as fatigue, diarrhea, musculoskeletal pain, and hot flashes. Patients with increased risk of seizure should not take enzalutamide. CONCLUSIONS: Enzalutamide is effective to slow progression of metastatic CRPC, to reduce prostate-specific antigen (PSA) levels, to decrease time to progression of PSA, to increase time to first skeletal-related events, and to increase quality of response rate. Enzalutamide was given at 160 mg/d for a median of 8 cycles of administration. Clinical trials are currently being conducted to observe if enzalutamide will be useful for treatment of other cancers and for early administration in prostate cancer.

RESUMO

OBJECTIVE: To review the epidemiology, pathophysiology, and treatments of Gaucher disease (GD), focusing on the role of enzyme replacement therapy (ERT), andsubstrate reduction therapy (SRT). DATA SOURCES: A literature search through PubMed (1984-May 2013) of English language articles was performed with terms: Gaucher's disease, lysosomal storage disease. Secondary and tertiary references were obtained by reviewing related articles. STUDY SELECTION AND DATA EXTRACTION: All articles in English identified from the data sources, clinical studies using ERT, SRT and articles containing other interesting aspects were included. DATA SYNTHESIS: GD is the most common inherited LSD, characterized by a deficiency in the activity of the enzyme acid ß-glucosidase, which leads to accumulation of glucocerebroside within lysosomes of macrophages, leading to hepatosplenomegaly, bone marrow suppression, and bone lesions. GD is classified into 3 types: type 1 GD (GD1) is chronic and non-neuronopathic, accounting for 95% of GDs, and types 2 and 3 (GD2, GD3) cause nerve cell destruction. Regular monitoring of enzyme chitotriosidase and pulmonary and activation-regulated chemokines are useful to confirm the diagnosis and effectiveness of GD treatment. CONCLUSIONS: There are 4 treatments available for GD1: 3 ERTs and 1 SRT. Miglustat, an SRT, is approved for mild to moderate GD1. ERTs are available for moderate to severe GD1 and can improve quality of life within the first year of treatment. The newest ERT, taliglucerase alfa, is plant-cell derived that can be produced on a large scale at lower cost. Eliglustat tartrate, another SRT, is under phase 3 clinical trials. No drugs have been approved for GD2 or GD3.

RESUMO

The Pharmacy Curriculum Outcomes Assessment (PCOA) is a standardized examination for assessing academic progress of pharmacy students. Although no other national benchmarking tool is available on a national level, the PCOA has not been adopted by all colleges and schools of pharmacy. Palm Beach Atlantic University (PBAU) compared 2008-2010 PCOA results of its P1, P2, and P3 students to their current grade point average (GPA) and to results of a national cohort. The reliability coefficient of PCOA was 0.91, 0.90, and 0.93 for the 3 years, respectively. PBAU results showed a positive correlation between GPA and PCOA scale score. A comparison of subtopic results helped to identify areas of strengths and weaknesses of the curriculum. PCOA provides useful comparative data that can facilitate individual student assessment as well as programmatic evaluation. There are no other standardized assessment tools available. Despite limitations, PCOA warrants consideration by colleges and schools of pharmacy. Expanded participation could enhance its utility as a meaningful benchmark.
