Background: Proton therapy (PRT) is an innovative radiotherapeutic modality for the treatment of cancer with unique ballistic properties. The depth-dose distribution of a proton beam reduces exposure of healthy tissues to radiations, compared with photon-therapy (XRT). To date, only few indications for proton-therapy, like pediatric cancers, chordomas, or intra-ocular neoplasms, are reimbursed by Health systems.

Utility values of responders and nonresponders are essential inputs in cost-effectiveness studies of radiation therapy for painful bone metastases but, to our knowledge, they have not been reported separately. We sought to determine the utility values of responders and nonresponders using data from a prospective observational study on bone metastases. The original prospective observational study was conducted at 26 centers in Japan.

Background And Purpose: Radiotherapy induces tumor cell killing by generating DNA double strand breaks (DSBs). The effectiveness of radiotherapy is significantly influenced by the repair of DSBs, which counteracts this lethal effect. Current investigations are focused on determining whether non-homologous end joining (NHEJ) or homologous recombination is the predominant repair pathway following proton and photon radiation.

The relative bioavailability and impact of food and the proton pump inhibitor rabeprazole on the pharmacokinetics of a maribavir powder-for-oral-suspension formulation was investigated in a Phase 1 open-label study in healthy adult volunteers. A single 200-mg maribavir dose was administered as the commercial tablet (Treatment A), powder formulation (Treatment B), or powder formulation with a high-fat/high-calorie meal (Treatment C) in Part 1, and as the powder formulation alone (Treatment D) or following administration of rabeprazole 20 mg once daily for 5 days (Treatment E) in Part 2. Maribavir maximum plasma concentration following Treatment B was 18% lower versus Treatment A, whereas the area under the concentration-time curve (AUC) from time 0 to the last quantifiable concentration or infinity were similar.

Chronic pain is a prevalent problem affecting approximately one out of every five adults in the U.S. The most effective way to treat chronic pain is with opioids, but they cause dangerous side effects such as tolerance, addiction, and respiratory depression, which makes them quite deadly.
