Comparative Study Controlled Clinical Trial
Adjusted Indirect Comparison Using Propensity Score Matching of Osimertinib to Platinum-Based Doublet Chemotherapy in Patients with EGFRm T790M NSCLC Who Have Progressed after EGFR-TKI.
An adjusted indirect comparison was conducted to assess efficacy outcomes, particularly overall survival (OS), of osimertinib versus platinum-based doublet chemotherapy in patients with epidermal growth factor receptor-mutated (EGFRm) T790M mutation-positive non-small-cell lung cancer (NSCLC) who had progressed following an EGFR tyrosine kinase inhibitor (TKI). Analysis of treatment effect from two separate trials had the potential to more accurately estimate the magnitude of OS benefit due to absence of confounding due to treatment switching from the control arm to the osimertinib arm of the ongoing randomized control trial, AURA3. ⋯ In this indirect comparison, osimertinib showed a statistically significant improvement in efficacy outcomes versus platinum-based doublet chemotherapy in patients with EGFRm T790M NSCLC who had progressed after EGFR-TKI therapy.

Randomized Controlled Trial
Pharmacokinetics of Oral and Intravenous Paracetamol (Acetaminophen) When Co-Administered with Intravenous Morphine in Healthy Adult Subjects.
Several features favor paracetamol (acetaminophen) administration by the intravenous rather than the oral route in the postoperative setting. This study compared the pharmacokinetics and bioavailability of oral and intravenous paracetamol when given with or without an opioid, morphine. ⋯ NCT02848729.

Multicenter Study Observational Study
Impact of Herpes Zoster and Post-Herpetic Neuralgia on Health-Related Quality of Life in Japanese Adults Aged 60 Years or Older: Results from a Prospective, Observational Cohort Study.
Herpes zoster (HZ) and its most frequent complication, post-herpetic neuralgia (PHN), have been shown to considerably impact quality of life (QoL). This has not yet been demonstrated in Japan. ⋯ HZ impaired QoL in daily activity performance and emotional and physical functioning. The negative impact on QoL was more prevalent in patients with a longer PHN duration compared with HZ without PHN. ClinicalTrials.gov identifier: NCT01873365.

Oral oxycodone/naloxone prolonged release (PR) [Targin®, Targinact®, Targiniq®] is a 12-hourly opioid receptor agonist and opioid receptor antagonist fixed-dose combination product that is approved in countries in the EU for the management of severe pain (adequately manageable only with opioid analgesics) in adults. Oral naloxone prevents oxycodone from binding to μ-receptors in the gastrointestinal (GI) tract, thereby counteracting opioid-induced constipation (OIC). In short-term (5- to 12-week) clinical trials of adults with moderate to severe, chronic pain and OIC (OXN3001, OXN3006, OXN3506), oxycodone/naloxone PR significantly improved OIC while providing noninferior analgesia relative to oxycodone PR; results were consistent between cancer and non-cancer patients in OXN3506. ⋯ Results in real-world studies were consistent with those in clinical trials. Oxycodone/naloxone PR was generally well tolerated, with nausea, hyperhidrosis, and diarrhoea (generally transient) reported as the most commonly occurring adverse events. Thus, oxycodone/naloxone PR is a useful treatment option to consider in adults with severe chronic pain that can be adequately managed only with opioid analgesics, particularly in those with OIC.

Extended-release (ER) opioids are associated with high rates of abuse. Recreational opioid users often manipulate ER formulations to achieve a high plasma concentration in a short amount of time, resulting in a more rapid and intense high. Patients may also manipulate ER tablets to facilitate swallowing, without recognizing that manipulation could increase release rate. The goal of this study was to assess the ability of oxycodone DETERx (Xtampza® ER, Collegium Pharmaceutical, Inc., Canton, MA, USA) and other commercially available ER opioid formulations with and without physicochemical abuse-deterrent characteristics to be manipulated by crushing in an in vitro setting. ⋯ Xtampza ER maintained its ER characteristics after crushing, unlike many other commercially available opioid formulations, including some formulated with abuse-deterrent properties. As such, Xtampza ER may be less appealing to abusers and offer a margin of safety for patients who manipulate dosage forms to facilitate swallowing.
