This study is designed to demonstrate the efficacy and assess safety and tolerability of oral daily alpelisib in participants with PIK3CA-related overgrowth spectrum (PROS).

Drug: Alpelisib

Safety, tolerability and efficacy of Descarte-08 in children, adolescents and young adults with childhood-onset systemic lupus erythematosus, ANCA-associated vasculitis, juvenile myasthenia gravis, and juvenile dermatomyositis

Drug: Descartes-08

This is a 3-part Phase 2 randomized study evaluating the safety and efficacy of the mutant-selective PI3Kα inhibitor, zovegalisib (RLY-2608), in adults and children with PIK3CA Related Overgrowth Spectrum (PROS) and malformations driven by PIK3CA mutation. Part 1 is a dose selection, Part 2 is a basket design with exploratory single-arm cohorts for various subpopulations of participants, and Part 3 is randomized, double-blinded study vs placebo.

Drug: Placebo

The trial will be an open label, single arm, phase 2 study to assess the tolerability and efficacy of HLX-1502 in participants with NF1 that are 16 years or older in age with progressive and/or symptomatic PN. This study will also investigate the safety and efficacy of HLX-1502 in a small cohort of 12 to 15 year olds.

Drug: HLX-1502

This study is conducted to confirm whether etavopivat works well at reducing the number of Vaso-occlusive crisis VOCs (sickle cell pain crises) caused by obstructions in blood vessels in adults and adolescents living with sickle cell disease. The study will also evaluate how well etavopivat can reduce the damage to different organs, improve your exercise tolerance and reduce fatigue in people with sickle cell disease.The participants will either get etavopivat or placebo. Which treatment the participants will get is decided by chance. Etavopivat is a new medicine and is currently being tested in other studies in addition to this one. The study will last for about 2 years.

Drug: Placebo

The purpose of this study is to demonstrate the efficacy and evaluate the safety and tolerability of mavorixafor in participants with congenital or acquired primary autoimmune and idiopathic chronic neutropenic disorders who are experiencing recurrent and/or serious infections as assessed by demonstrating its clinical benefit and increasing levels of circulating neutrophils.

Drug: Placebo

This phase II trial tests the safety, side effects, best dose and activity of tovorafenib (DAY101) in treating patients with Langerhans cell histiocytosis that is growing, spreading, or getting worse (progressive), has come back (relapsed) after previous treatment, or does not respond to therapy (refractory). Langerhans cell histiocytosis is a type of disease that occurs when the body makes too many immature Langerhans cells (a type of white blood cell). When these cells build up, they can form tumors in certain tissues and organs including bones, skin, lungs and pituitary gland and can damage them. This tumor is more common in children and young adults. DAY101 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Using DAY101 may be effective in treating patients with relapsed or refractory Langerhans cell histiocytosis.

The main purpose of this study in participants with PIK3CA-mutated LyM is to assess the change in radiological response and symptom severity upon treatment with alpelisib film-coated tablets (FCT) as compared to placebo.
