Cangrelor (Kengrexal(®), Kengreal(™)) is an intravenously administered P2Y12 receptor inhibitor. It is direct-acting and reversible, with a very rapid onset and offset of action. ⋯ The rate of severe or life-threatening non-coronary artery bypass graft-related, GUSTO-defined bleeding at 48 h did not significantly differ between cangrelor and clopidogrel recipients. In conclusion, intravenous cangrelor is an important new option for use in patients undergoing PCI who have not been treated with oral P2Y12 inhibitors.

An improved understanding of cancer genetics and immune regulatory pathways, including those associated with evasion of immune surveillance by tumours, has culminated in the development of several targeted therapies. One such strategy that acts to negate evasion of immune surveillance by tumours is inhibition of the programmed cell death receptor-1 (PD-1) checkpoint pathway. Intravenous nivolumab (Opdivo(®)), a PD-1 checkpoint inhibitor, is approved or in pre-registration in various countries for use in adult patients with advanced melanoma, with the recommended monotherapy dosage being a 60-min infusion of 3 mg/kg once every 2 weeks. ⋯ In addition, nivolumab monotherapy significantly prolonged PFS and improved ORRs compared with ipilimumab monotherapy. The optimal combination regimen for immune checkpoint inhibitors remains to be fully elucidated, with various combination regimens and different sequences of individual immunotherapies currently being investigated in ongoing clinical trials. Given the significant improvements in outcomes associated with nivolumab in clinical trials, nivolumab monotherapy or combination therapy is a valuable first-line or subsequent treatment option for adult patients with unresectable or metastatic melanoma, irrespective of BRAF mutation status.

Apremilast (Otezla(®)) is an oral phosphodiesterase 4 inhibitor indicated for the twice-daily treatment of adults with psoriasis and psoriatic arthritis (PsA). Its use in these patient populations has been assessed in two phase III clinical trial programmes (ESTEEM and PALACE). At 16 weeks in the two ESTEEM trials, apremilast reduced the severity and extent of moderate to severe plaque psoriasis, including nail, scalp and palmoplantar manifestations, versus placebo in adults, with these benefits generally being sustained over 52 weeks of treatment. ⋯ These PsA benefits were generally sustained for up to 104 weeks of treatment; skin involvement, enthesitis and dactylitis also improved with the drug. Apremilast was generally well tolerated, with the most common adverse events being diarrhoea and nausea in the first year of treatment (usually occurring in the first 2 weeks after the first dose and resolving within 4 weeks) and nasopharyngitis and upper respiratory tract infection with continued treatment. Although further longer-term and comparative efficacy and tolerability data would be beneficial, the current clinical data indicate that apremilast is an effective and well tolerated option for the management of psoriasis and PsA in adults.

Endocrine therapy is a key component of adjuvant treatment for premenopausal patients with endocrine-responsive tumors. It is commonly well tolerated, although side effects are a main concern in the selection of treatment options. Tamoxifen is still considered an adequate endocrine therapy in a large group of premenopausal patients (e.g. lower-risk patient, presence of co-morbidities, patient preference). ⋯ However, premenopausal patients include heterogeneous subsets of women and tumors where costs and benefits of adjuvant endocrine therapy should be properly weighted. Issues specific for premenopausal patients, related to desire for pregnancy, family planning, safety, quality of life and subjective side effects, should be a priority in the therapeutic algorithm. Therefore, selecting the best-tolerated agent can enhance adherence to therapies and reduce the impact on quality of life and health status for these younger patients.
