Latest Keytruda Approval Promising for Mesothelioma Patients

The U.S. Food and Drug Administration (FDA) expanded its approval of pembrolizumab for first-line treatment of metastatic non-small cell lung cancer last week, moving it closer to becoming a viable treatment option for patients with pleural mesothelioma. Pembrolizumab is marketed by Merck &Co. under the brand name Keytruda. It helps the body’s immune system detect and destroy cancer cells. The FDA approved its first-line use in combination with pemetrexed and carboplatin, two chemotherapy agents used regularly for mesothelioma. Pembrolizumab, the most well-known immunotherapy drug, is being studied for use with various cancers in more than 400 clinical trials worldwide, including 10 for mesothelioma but none in combination with chemotherapy. The FDA previously approved its use for melanoma, head and neck cancers and Hodgkin lymphoma. First FDA Approval with Chemotherapy Before last week’s expansion, pembrolizumab was approved for non-small cell lung cancer (NSCLC), but only as a single agent and only with tumors that expressed the PD-L1 protein. That protein is found in many cancers, but only in half of mesothelioma patients. This was the first approval as part of a chemotherapy combination and the first without a need for PD-L1 expression. “Now that there is clinical evidence the combination is effective in a common malignancy like lung cancer, the next logical step is to test it in other cancer types, including rare ones like mesothelioma,” Dr...

In this study we tried to explore Diazepam as a repurposed drug and tested it in Neuroblastoma (Neuro 2a) cells. Diazepam loaded Poly Lactic Acid Nanoparticles were developed (D-PLA-NPs) using nanoprecipitation method. Entrapment efficiency was found to be ± 99.7% and drug loading was ± 12.88%. The particle size developed was 188.8 nm and zeta potential was −25.6 millivolt. Dissolution profiles were studied in PBS (pH 7.4) or simulated media, almost 50% release was observed within 6 h. In vitro, cytotoxicity was analyzed using MTT assay where dose-dependent cytotoxicity was observed for developed D-PLA-NPs.

Abstract Two novel electrochemiluminescence (ECL) deoxyribosensors are designed for assay of early lung cancer biomarker (NAP2) using the DNA three-way junction (DNA-TWJ) inserted NAP2 binding aptamer between two double-helical stems and labeled with ruthenium (II) complex (Ru) (NBAT-Ru) taken as molecular recognition element. The signal-off ECL deoxyribosensor was fabricated by covalently coupling the 5'-NH2-(CH2)6-NBAT-Ru to glassy carbon electrode surface modified with 4-aminobenzoic acid (4-ABA). After combining NAP2 and NBAT-Ru, the changed conformation of NBAT-Ru altered the distance between Ru complex and e...

Abstract The expression level of miRNA-21 is closely related to the occurrence and development of cancer, especially in gastrointestinal cancer. Monitoring miRNA-21 has clinical application in the diagnosis and evaluation of gastrointestinal cancer. A turn-on ratiometric fluorescence bioassay based on the T7 exonuclease-mediated cyclic enzymatic amplification method was developed for miRNA-21 determination by using carbon dots (CDs) and FAM-labeled ssDNA as the signal source. CDs demonstrated the triple functions of built-in internal fluorescence, probe carrier, and quencher in this strategy. In the absence of miR...

Abstract Development of a mitochondria-targeting fluorescent probe with large Stokes shift and long-wavelength emission was benefit for accurate detection of hypoxic status, which was known as a major factor of the tumor physiology and influence important pathological processes. However, an efficient optical approach for simultaneously achieving such merits was still lacking. In this work, a turn-on fluorescence probe (HBT-NP) was designed to assess the hypoxic condition of tumor cells by detecting nitroreductase (NTR). Probe HBT-NP was constructed by conjugating 4-nitrobenzyl moiety as reaction site for NTR to 2-...

ZinAbstractThe cancer treatment modalities have been developed rapidly with the aim to maximize the absorbed dose toward the cancer cells while sparing the healthy tissues. The use of high atomic number, Z nanomaterials has become interest as it offers the possibilities such as destroying cancer tumor with minimal damage to the healthy tissues. The study aimed to evaluate the role of methylene blue as it reduced the self-polymerization as well as to measure the dose enhancement effect of Zin...

CONCLUSIONS: Non-functional, metastatic Pan-NETs may transform to insulin secreting lesions, with negative impact on prognosis. Therefore, if symptoms as hypoglycemia develops continuous follow-up of clinical parameters, biochemical profiles of pancreatic hormones and histopathological evaluation of proliferation is suggested to detect changes in characteristics of these malignant neoplasms.

Authors: Aresta C, Passeri E, Corbetta S Abstract Current primary hyperparathyroidism (PHPT) clinical presentation is asymptomatic in more than 90% of patients, while symptoms concern osteoporosis and rarely kidney stones. Here, we retrospectively investigated the prevalence of PHPT patients presenting with hypercalcemic-related symptoms (HS-PHPT) as cognitive impairment, changes in sensorium, proximal muscle weakness, nausea and vomiting, constipation, and severe dehydration, in a single center equipped with an emergency department and described their clinical features and outcome in comparison with a series of as...
