RESUMO
Alirocumab (Praluent®), a proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitor that has been co-developed by Regeneron Pharmaceuticals, Inc. and Sanofi (formerly sanofi-aventis), is approved globally for use in adults with established cardiovascular disease, primary hyperlipidemia [including heterozygous familial hypercholesterolemia (HeFH) or homozygous familial hypercholesterolemia (HoFH)]. In November 2023, based on clinical data in patients aged 8-17 years, alirocumab received its first pediatric approval in the EU as an adjunct to diet alone, or in combination with a statin and/or other low-density lipoprotein cholesterol (LDL-C)-lowering therapies, in pediatric patients aged ≥ 8 years with HeFH. Alirocumab was approved a few months later in the US for use as an adjunct to diet and other LDL-C-lowering therapies in pediatric patients aged ≥ 8 years with HeFH to reduce LDL-C. This article summarizes the milestones in the development of alirocumab leading to this first pediatric approval for HeFH.

Topical ruxolitinib 1.5% cream (Opzelura®), a Janus kinase (JAK) inhibitor, is the first treatment to be approved in several countries for use in patients aged ≥ 12 years with non-segmental vitiligo. In the identical phase III TRuE-V1 and TRuE-V2 trials, significantly more ruxolitinib cream recipients were able to achieve statistically significant and clinically meaningful facial and total body repigmentation, as well as reductions in vitiligo noticeability, compared with vehicle recipients. Efficacy was sustained in longer-term analyses to week 104 of treatment. Ruxolitinib 1.5% cream was generally tolerable in these trials; the most common treatment-related adverse events were acne, pruritus and exfoliation, all at the application site. As with orally administered JAK inhibitors, topical ruxolitinib carries boxed warnings in the USA for serious infections, mortality, malignancy, major adverse cardiovascular events (MACE) and thrombosis, although the incidences were low with topical application. Thus, topical ruxolitinib 1.5% cream is an effective and generally tolerable treatment option for patients aged ≥ 12 years with non-segmental vitiligo.
Non-segmental vitiligo is a chronic autoimmune disease where the skin throughout the body loses its pigmentation, and is usually managed with topical therapies, light therapy or surgery. Topical ruxolitinib 1.5% cream (Opzelura®) is the first treatment approved in several countries for patients aged ≥ 12 years with non-segmental vitiligo. It inhibits Janus kinase (JAK) proteins, reducing the destruction of skin pigment-producing cells. In two clinical trials, significantly more ruxolitinib cream recipients achieved significant and meaningful skin repigmentation compared with patients who received a non-medicated cream; these results were sustained to week 104 of treatment. Ruxolitinib 1.5% cream was generally tolerable; the most common treatment-related adverse events were acne, itchiness and exfoliation, all at the application site. Topical ruxolitinib has special warnings in the USA for major adverse cardiovascular events (MACE), blood clots, serious infections, death and cancer (associated with the use of oral JAK inhibitors), although incidence rates for these adverse events were low in the clinical trials. Topical ruxolitinib 1.5% cream is an effective and generally tolerable treatment option for patients aged ≥ 12 years with non-segmental vitiligo.

Sacituzumab govitecan (TRODELVY®) is a first-in-class trophoblast cell-surface antigen 2 (Trop-2)-directed antibody and topoisomerase I inhibitor conjugate that is approved globally as monotherapy for the treatment of adults with unresectable locally advanced or metastatic, hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-; defined as immunohistochemistry 0, 1+ or 2+ and in situ hybridization-negative) breast cancer who have received endocrine-based therapy and ≥ 2 additional systemic therapies in the advanced setting. In the phase III TROPiCS-02 trial, intravenous sacituzumab govitecan demonstrated statistically significant and clinically meaningful improvements in progression-free survival and overall survival compared with physician's choice of chemotherapy (capecitabine, eribulin, gemcitabine or vinorelbine) in adults with metastatic HR+/HER2- breast cancer. Sacituzumab govitecan had a generally manageable tolerability profile in these patients; the most common treatment-related grade ≥ 3 adverse events included neutropenia, diarrhoea, leukopenia, anaemia, fatigue and febrile neutropenia. Sacituzumab govitecan carries regulatory warnings for severe neutropenia and severe diarrhoea. Sacituzumab govitecan demonstrated an overall benefit in terms of health-related quality of life. Current evidence indicates that sacituzumab govitecan is an effective treatment option, with a generally manageable tolerability profile, for patients with pre-treated, unresectable locally advanced or metastatic HR+/HER2- breast cancer.
The most common type of breast cancer is hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2−), and management of metastatic (spread to areas near the breast or to other areas) HR+/HER2− breast cancer eventually requires chemotherapy or surgery if resistance develops. Intravenous sacituzumab govitecan (TRODELVY®) is approved globally for adults with inoperable or metastatic HR+/HER2− breast cancer who have previously received endocrine therapy and ≥ 2 additional systemic therapies for advanced disease. In a clinical trial, sacituzumab govitecan therapy significantly improved the duration adults with metastatic HR+/HER2− breast cancer survived without their disease progressing, along with overall survival time, versus standard chemotherapy. The tolerability profile of sacituzumab govitecan was generally manageable; the most common side effects were decreased neutrophil count, diarrhoea and decreased white blood cell count. Sacituzumab govitecan can severely reduce neutrophil count and cause severe diarrhoea. Sacituzumab govitecan demonstrated an overall benefit in terms of health-related quality of life. Current evidence indicates that sacituzumab govitecan is an effective treatment option, with a generally manageable tolerability profile, for patients with pre-treated, inoperable or metastatic HR+/HER2− breast cancer.
