The immune system plays a vital role in regulating tumor growth, and the oncology community has witnessed an exciting resurgence in clinical research to develop effective immunotherapeutic strategies. The utility of these strategies in advanced melanoma has been at the forefront of these developments. ⋯ Pembrolizumab is a humanized IgG4 anti-PD-1 antibody that exerts its anti-tumor effect through blocking the interaction of the immune inhibitory molecule PD-1 with its ligands. Its effect has been most convincingly demonstrated in the setting of advanced melanoma, with growing evidence of clinical responses across a broad spectrum of other solid and hematological malignancies.

ReviewAfamelanotide (CUV1647) in dermal phototoxicity of erythropoietic protoporphyria.
The application of afamelanotide, an α-melanocyte stimulating hormone agonistic analogue to protoporphyria, a disease with absolute sunlight-intolerance is discussed. The clinics, genetics and existing therapies of protoporphyria are described. The physiological receptor-mediated intracellular signaling of α-melanocyte stimulating hormone and effects of receptor variants are outlined. ⋯ The trial results were significant, although the effects were not very large in absolute terms, and the risk-safety profile is favorable today. Based on the high compliance rate and the excellent consistency in clinical effectiveness during six years of compassionate use program in Switzerland, we expect afamelanotide and analogues to become a prospective therapeutic tool. Moreover, we hope that dosage forms suitable for children will be developed in future, as children and adolescents suffer most in protoporphyria.

ReviewUsing real-world healthcare data for pharmacovigilance signal detection - the experience of the EU-ADR project.
A prospective pharmacovigilance signal detection study, comparing the real-world healthcare data (EU-ADR) and two spontaneous reporting system (SRS) databases, US FDA's Adverse Event Reporting System and WHO's Vigibase is reported. The study compared drug safety signals found in the EU-ADR and SRS databases. ⋯ The EU-ADR system may have a greater potential for detecting signals for events occurring at higher frequency in general population and those that are commonly not considered as potentially a drug-induced event. Factors influencing various differences between the datasets are discussed along with potential limitations and applications to pharmacovigilance practice.

ReviewFentanyl buccal tablet for the treatment of cancer-related breakthrough pain.
Fentanyl buccal tablet (FBT) (FENTORA) is indicated for the management of breakthrough pain (BTP) in patients with cancer pain and who are tolerant to ≥60 mg of oral morphine equivalents, at least with the current availability of the minimal strength of 100 μg. FBT uses the OraVescent technology to further increase the rate and extent of absorption of fentanyl. ⋯ It has been recommended that administration should be tailored to the patient's individual requirement, through dose titration starting from the lowest dose to find the effective dose. However, recent studies have demonstrated that predictable doses calculated from the basal opioid regimen are safe and more effective than doses achieved after dose titration.

EditorialPrediction of treatment outcomes in major depressive disorder.
Improving the treatment of major depressive disorder will require identification of moderators that predict differential outcomes across treatments at the level of the individual patient, referred to as precision medicine. Currently, there are no biological measures demonstrated to enhance treatment selection accuracy although there are some clinical variables that have prognostic value. ⋯ Genetic combination tests, systemic inflammation, electroencephalography and neuroimaging, in particular, show significant potential for near-term development as clinically meaningful moderators for use in treatment selection. Ultimately, combinations of moderators may provide the greatest level of precision in selecting optimal treatment approaches for individual depressed patients.
