Sarecycline hydrochloride (Seysara) is a novel, narrow-spectrum tetracycline derivative approved by the U.S. Food and Drug Administration (FDA) in October 2018 for the treatment of inflammatory non-nodular moderate to severe acne vulgaris. It was initially developed by Paratek Pharmaceuticals, Inc. (U.S.) and Allergan plc (U.S.), which later was acquired by Almirall S.A. (Barcelona, Spain). Almirall S.A. obtained U.S. FDA approval of oral sarecycline tablets under the trade name Seysara. Sarecycline exhibits antibacterial activity against important skin/soft tissue pathogens with targeted activity against Cutibacterium acnes--an anaerobic Gram-positive bacterium linked with acne lesions--and also exerts anti-inflammatory effects as do other tetracyclines used in the treatment of acne vulgaris. Interestingly, unlike the broad-spectrum tetracyclines, sarecycline is less potent against aerobic Gram-negative bacilli and anaerobic bacteria associated with endogenous intestinal microbial flora. This provides it with a more specific antibacterial spectra with lower chances of adverse off-target antibacterial effects, thus making it a promising choice of treatment over others in its class. It has also demonstrated low propensity to resistance as compared with other tetracyclines and is also active against tetracycline-resistant Staphylococcus aureus as well as erythromycin- and clindamycin-resistant C. acnes strains. Sarecycline has successfully undergone numerous phase I, phase II and three phase III studies establishing it as a well-tolerated once-daily oral drug available as a tablet for the treatment of patients 9 years of age or above.

ROS1 gene fusions account for approximately 1-2% of all cases of non-small cell lung cancer (NSCLC). Similarly to anaplastic lymphoma kinase (ALK)-positive NSCLC, patients with ROS1+ NSCLC tend to have minimal smoking and be of the female sex. In most cases, adenocarcinoma is the dominant histology. The ROS1 gene has homology to ALK and this structural similarity formed the basis for utilizing ALK inhibitors for ROS1+ NSCLC. On the basis of impressive progression-free survival of 19.2 months from the PROFILE 1001 trial, crizotinib obtained Food and Drug Administration (FDA) approval as first-line therapy for treatment of ROS1+ NSCLC. Since then, there has been a growing appreciation of the incidence of brain metastases in ROS1+ NSCLC and rates of central nervous system progression on crizotinib. Additionally, appreciation of novel resistance mechanisms to crizotinib has led to the development of newer tyrosine kinase inhibitors (TKIs). In this review, we highlight known and emerging TKIs for the management of ROS1+ NSCLC.

Duchenne muscular dystrophy is the most common lethal X-linked genetic disorder, characterized by progressive muscle loss, with cardiac and respiratory complications. It is caused by a lack of dystrophin protein due to mutations in the DMD gene, which can disrupt the reading frame of the dystrophin primary transcript. Antisense oligonucleotides such as phosphorodiamidate morpholino oligomers (PMOs) can induce exon skipping during pre-mRNA splicing and restore the reading frame of the DMD primary transcript. The resulting dystrophin protein is internally deleted but partially functional. Viltolarsen, also known as NS-065/NCNP-01, is a PMO developed through comprehensive sequence optimization and is designed to skip exon 53 on the DMD primary transcript. Exclusion of exon 53 from the DMD primary transcript can treat 8-10% of DMD patients worldwide. This review paper summarizes the mechanism of action, pharmacokinetics and safety of viltolarsen from preclinical and clinical trials.

Plaque psoriasis is the commonest form of psoriasis affecting about 85% of those patients with the condition. Risankizumab was developed as a high-affinity humanized monoclonal antibody specific for the p19 subunit of interleukin-23 (IL-23p19). Clinical trials demonstrated that risankizumab was very effective in patients with moderate to severe plaque psoriasis causing total clearing of the condition as evidenced by Psoriasis Scalp Severity Index (PSSI100) and static Physician's Global Assessment (sPGA) of 0 in more than 50% of patients after 52 weeks of treatment. Risankizumab has been approved by the Food and Drug Administration (FDA) for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy as a dose of 150 mg administered by subcutaneous injection at week 0, week 4 and every 12 weeks thereafter.

Generalized pustular psoriasis (GPP) is a severe psoriasis form that can be refractory to several systemic treatments. The role of interleukin (IL)-17/ T-helper 17 (Th17) axis inhibitors in the therapy of GPP is not fully established. The objective of this paper is to summarize the existing information on the efficacy and safety of secukinumab, ixekizumab and brodalumab in GPP. Articles published in the English language and derived from the databases MEDLINE (PubMed), Embase and Scopus were assessed for this study. Although the existing data on the potential therapeutic benefit of these agents in the treatment of GPP are encouraging, further studies are needed so as to provide sufficient evidence for their use in this serious condition.
