This research aims to evaluate antibiotic treatments for acute pyelonephritis AP in children aged 1 month to 3 years. It compares a shorter intravenous IV antibiotic course of 3 days alone to a longer treatment consisting of 3 days IV followed by 7 days of oral antibiotics. The goal is to see if the shorter IV treatment is as effective in curing AP and preventing recurrence and renal scarring, while reducing the risk of antibiotic resistance and preserving gut microbiota diversity. Participants are randomly assigned to one of two groups. The experimental group receives only 3 days of IV antibiotics with ceftriaxone andor amikacin, after which treatment is stopped. The control group receives the usual care of 3 days IV antibiotics followed by 7 days of oral antibiotics, either cotrimoxazole or cefixime. The study includes collection of fecal or rectal swabs and blood tests to assess microbiota and resistance. Treatment effectiveness and safety are compared between groups. During the study, children are monitored for fever, symptoms, and urine cultures to confirm infection clearance. Researchers measure recurrence of febrile urinary tract infections within 28 days after treatment ends and follow clinical cure at 10 or 17 days depending on the group. Additional assessments include monitoring recurrence at 90 days, antimicrobial resistance in gut bacteria, and intestinal microbiota diversity over about a month. Participation lasts through treatment and follow-up visits up to several weeks.

Researchers are studying pulmonary arterial hypertension PAH, a condition where lung blood vessels become thick and narrow, causing high blood pressure in the lungs and making it hard for the heart to work. PAH can cause difficulty breathing and limit activity. While standard treatments help symptoms, they do not stop the disease from worsening. This research focuses on sotatercept, a targeted therapy aimed at specific proteins involved in PAH, to learn about its long-term safety and tolerability when added to usual PAH treatments. Participants in this long-term follow-up study, who previously took part in certain sotatercept trials, may continue receiving sotatercept by subcutaneous injection every three weeks. Those coming from blinded studies start at 0.3 mgkg with possible increases up to 0.7 mgkg, while those from unblinded studies continue their current dose with possible titration to 0.7 mgkg. The study monitors participants over an extended period to assess continued effects alongside their usual PAH therapy. During the study, participants will have regular assessments including monitoring for adverse events, blood tests for blood components and chemistry, body weight, blood pressure, and ECG readings. Researchers will also evaluate exercise capacity, heart function markers, and risk scores related to PAH. The study aims to follow participants for up to approximately 7 to 8 years to understand long-term safety, treatment tolerability, and health changes while using sotatercept with standard PAH care.

This first-in-human study aims to better understand how KK8123 behaves in the body and its effects on patients with this condition. The study is sponsored by Kyowa Kirin Co., Ltd. and includes an optional safety extension period. The study includes a Screening Period of up to 28 days, followed by Part 1, which is a Dose Escalation Period consisting of a planned Treatment Period and an Observation Period lasting 32 to 44 weeks. Part 2 is an optional Extension Period for additional safety evaluation. Participants receive subcutaneous doses of KK8123 at different levels, including low dose single dose, mild dose multiple doses, and high dose multiple doses, with dosing confirmed for later cohorts. The study groups include several cohorts receiving escalating doses and an extension group. Participants will undergo multiple assessments during the study, including laboratory tests for hematology and clinical chemistry, measurement of serum phosphorus levels, echocardiograms, renal ultrasounds, and monitoring of vital signs such as heart rate and blood pressure. Researchers will track treatment-emergent adverse events TEAEs and measure KK8123 drug concentrations over time. Follow-up periods last up to 44 weeks in Part 1 and up to 52 weeks in Part 2. Participants are expected to adhere to study visit schedules and complete all assessments throughout their involvement.

Researchers are studying people with idiopathic pulmonary fibrosis IPF or progressive pulmonary fibrosis PPF who have previously taken nerandomilast in another study. The aim is to assess how well patients tolerate long-term treatment with nerandomilast and to evaluate whether it improves lung function and delays worsening symptoms, hospital visits, or death. This open-label extension trial is sponsored by Boehringer Ingelheim and focuses on treatment over an extended period. Participants take nerandomilast tablets for up to 1 year and 10 months while continuing their usual pulmonary fibrosis treatments. The study involves a single treatment group receiving the drug, and no placebo or comparison groups. Regular visits with doctors help monitor health and collect data during this extended treatment phase. Throughout the study, participants undergo regular lung function tests and health assessments to track any adverse events and changes in lung capacity. The main outcome measured is the occurrence of any adverse events for up to about 99 weeks. Secondary outcomes include changes in forced vital capacity and time to worsening of disease symptoms or hospitalization. The study includes ongoing safety monitoring with a total participation time of up to nearly two years.

Researchers are evaluating the safety, tolerability, and effectiveness of two drugs, inebilizumab and blinatumomab, in adults with active and refractory autoimmune diseases such as systemic lupus erythematosus SLE with nephritis and rheumatoid arthritis RA. This phase 2, open-label, multicenter trial aims to better understand how these drugs work in these conditions and their impact on disease activity and kidney health. Participants will receive inebilizumab through intravenous IV infusions in different dosing schedules, or blinatumomab through subcutaneous SC injections at varying doses depending on the subprotocol group. The study includes several parts focusing on different autoimmune conditions and treatment regimens, with some parts no longer recruiting new participants. During the trial, participants will undergo regular assessments including monitoring for adverse events, evaluation of disease activity using specific clinical scores, kidney function tests, and antibody levels. Researchers will track safety and treatment responses over a period of up to 52 weeks, with visits occurring at scheduled intervals to collect data and monitor participant health.

This research aims to evaluate the effects of different doses of vosoritide and compare the therapeutic dose of vosoritide to human growth hormone hGH in children diagnosed with idiopathic short stature ISS. The study is a Phase 2, randomized, controlled trial that seeks to understand how these treatments influence growth in affected children. Participants will first undergo a minimum 6-month observation period to assess their baseline growth. Then, those assigned to the vosoritide and placebo groups will receive randomized treatment for at least 6 months, with placebo limited to a maximum of 6 months. After this, open-label vosoritide treatment will continue until participants reach near-final adult height or at least 16 years for females and 18 years for males, whichever is later. Participants randomized to the hGH group will receive open-label hGH treatment for a minimum of 4 years. Study treatments involve daily injections. Throughout the study, participants will attend regular visits for clinical and imaging assessments, including evaluations of hips and lower extremities. Researchers will monitor safety concerns such as hypotension, fractures, and slipped capital femoral epiphysis, with oversight from an independent Data Monitoring Committee. The main outcomes measured include changes in annualized growth velocity at 6 months and height changes over 4 years. Follow-up assessments will continue as needed, including safety monitoring, until study completion, which could last up to 15 years.

Researchers are comparing INCA033989 with the best available therapy for adults who have essential thrombocythemia ET with a CALR mutation and have previously received cytoreductive treatment. The study aims to evaluate the effects of these treatments on this specific patient group. It is a Phase 3 clinical trial sponsored by Incyte Corporation to assess treatment responses and safety. Participants will be randomly assigned to receive either INCA033989 administered intravenously or the best available therapy chosen by their doctor. The treatments are given according to the study protocol. The study focuses on treatment outcomes over a period of weeks, including response durability and symptom changes, with assessments at specified timepoints. During the study, participants will have regular visits to monitor their clinical and hematologic responses, symptoms, and any side effects. Researchers will collect data on mutation levels, symptom questionnaires, and fatigue assessments up to 48 weeks. Safety monitoring will continue for 60 days following the last dose. The total duration of participation may extend up to several months as outlined by the trial schedule.

Researchers are evaluating the safety and effects of L606 in adults with pulmonary hypertension caused by interstitial lung disease PH-ILD, WHO Group 3. This phase 3 study aims to determine if L606 helps improve the distance people can walk in six minutes, an important test for lung and heart health. The research also looks at how long it takes for the condition to worsen while taking L606 compared to placebo. Participants are randomly assigned to receive either L606, a liposomal form of treprostinil inhaled through a study-issued nebulizer, or a matching placebo with no active medicine. After the initial blinded study period, participants may join an open-label extension where everyone receives L606. Doctors monitor the effects and any side effects closely throughout the study. During the trial, participants will undergo six-minute walk tests at various times to measure their walking distance and track changes. Researchers will also watch for hospitalizations, deaths related to lung or heart issues, lung transplants, and significant declines in walking ability. Safety is monitored regularly to ensure L606 is tolerable. The study is expected to continue until late 2031, with multiple assessments throughout this period.

The study is sponsored by Novartis Pharmaceuticals and includes both pediatric and adult participants aged 1 to 100 years.

Researchers are evaluating Mim8, a new medicine designed to help people with haemophilia A, including those with or without inhibitors. Mim8 aims to prevent bleeding episodes by replacing the function of the missing clotting factor VIII. This long-term study will last up to 5.5 years, ending either when Mim8 is approved in the participants country or by June 2028, whichever comes first. The study includes participants who have been involved in earlier related studies or are new infants with severe haemophilia A. Participants will receive Mim8 as a preventive treatment through subcutaneous injections. Depending on their entry point, participants may use an enhanced cartridge or a DV3407 pen-injector device for administering Mim8. The treatment is given regularly over the study period, with participants potentially receiving up to 262 injections. In the event of bleeding, additional haemostatic medications may be used as agreed with the study doctor. Female participants who are pregnant, breastfeeding, or planning pregnancy during the study are not eligible. During the study, participants will be monitored for any side effects, including injection site reactions and the development of antibodies against Mim8. Researchers will also track bleeding episodes, Mim8 blood levels, and device handling for some participants. Participants and their representatives will complete diaries and questionnaires about their treatment and health. Safety will be carefully followed throughout the study, which may last several years depending on individual enrollment and study progress.
