Clinical trials

This study is open to adults with certain kidney conditions, including secondary focal segmental glomerulosclerosis (sFSGS), treatment-resistant primary minimal change disease (TR-pMCD), Alport Syndrome (AS), and treatment-resistant primary membranous nephropathy (TR-pMN). Adolescents with treatment-resistant primary MCD can also participate in this study. The purpose of this study is to find out whether a medicine called BI 764198 helps people with these kidney conditions. Participants are put into 2 groups randomly, which means by chance. One group takes BI 764198 tablets, and the other group takes placebo tablets. Placebo tablets look like BI 764198 tablets but do not contain any medicine. Participants take a tablet once a day for 20 weeks. All participants also continue their standard medication for their kidney condition during the study. Participants have twice the chance of being placed in the BI 764198 group than in the placebo group. Participants are in the study for about 7 months. During this time, they visit the study site 6 times and have 3 phone calls. Doctors regularly test the protein levels in participants' urine by collecting urine samples. They also check kidney function by taking blood samples. The results are compared between the two groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

Alopecia areata (AA) is a disease that happens when the immune system attacks hair follicles and causes hair loss. AA usually affects the head and face, but hair loss can happen on any part of the body. The purpose of this study is to assess how safe, effective, and tolerable upadacitinib is in adolescent and adult participants with severe AA. Upadacitinib is an approved drug being investigated for the treatment of AA. In Study 1 and Study 2 and Study 4 Period A, participants are placed in 1 of 3 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 5 chance that participants will be assigned to placebo. In Study 1 and Study 2 and Study 4 Period B, participants originally randomized to upadacitinib dose group in Period A will continue their same treatment in Period B. Participants originally randomized to Placebo in Period A will either remain on placebo in Period B, or be randomized in 1 of 2 groups, based off of their Severity of Alopecia Tool (SALT) score. Participants who complete Study 1, Study 2 or Study 4, can join Study 3 and may be re-randomized to receive 1 of 2 doses of upadacitinib for up to 108 weeks. Around 1500 participants with severe AA will be enrolled in the study at approximately 280 sites worldwide. Participants will receive oral tablets of either upadacitinib or placebo once daily for up to 160 weeks with the potential of being re-randomized into a different treatment group at Weeks 24 and 52. Participants will be followed up for up to 30 days after last study drug dose. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

The purpose of this protocol is to evaluate the efficacy and safety of tulisokibart in participants with moderately to severely active Crohn's disease. Study 1's primary hypotheses are that at least 1 tulisokibart dose level is superior to placebo in the proportion of participants achieving clinical remission per Crohn's Disease Activity Index score (\<150, US/FDA) or per stool frequency and abdominal pain score (EU/EMA) and in the proportion of participants achieving endoscopic response at Week 52 (US/FDA and EU/EMA), and that at least 1 tulisokibart dose level is superior to placebo in the proportion of participants achieving clinical remission per Crohn's Disease Activity Index score (\<150, US/FDA) or per stool frequency and abdominal pain score (EU/EMA) and in the proportion of participants achieving endoscopic response at Week 12 (US/FDA and EU/EMA). Study 2's primary hypothesis is that at least 1 tulisokibart dose level is superior to placebo in the proportion of participants achieving clinical remission per Crohn's Disease Activity Index score (\<150, US/FDA) or stool frequency and abdominal pain score (EU/EMA) and in the proportion of participants achieving endoscopic response at Week 12 (US/FDA and EU/EMA).

This study aims to compare the efficacy of vericiguat versus placebo on change in n-terminal pro-brain natriuretic peptide (NTproBNP) from baseline to Week 16 of the Base Period. The primary hypothesis is that vericiguat is superior to placebo in reducing NT-proBNP at Week 16 of the Base Period.

The goal of this observational study is to compare objective parameters of skin barrier function between healthy adult women who regularly use UV lamps during nail treatments and women who do not use UV lamps. The main questions it aims to answer are: * Do women who regularly use UV lamps for nail treatments show differences in skin barrier function compared to women who do not use UV lamps? * Are transepidermal water loss, skin hydration, and erythema associated with regular exposure to UV lamps used for nail treatments? * Does the duration of UV lamp use influence skin barrier function parameters? Researchers will compare women who regularly use UV lamps during nail treatments with women who have natural nails and do not regularly expose their hands to UV lamps. Participants will: * Attend a single study visit. * Complete a short questionnaire regarding nail care habits and duration of UV lamp use. * Undergo non-invasive measurements of skin barrier function on the hands, including transepidermal water loss, skin hydration, and erythema assessments.

The purpose of this study is to evaluate the long-term efficacy and safety of combined formulation of xanomeline tartrate/trospium chloride in an immediate release (IR) capsule (KarXT) and xanomeline enteric capsules (KarX-EC) in participants with agitation associated with Alzheimer's Disease who completed the parent studies CN012-0023 or CN012-0024.

In this study, researchers will learn more about the use of felzartamab in participants with immunoglobulin A nephropathy (IgAN). IgAN is a kidney disease caused by the buildup of an antibody called IgA in the kidneys over time. In people with IgAN, abnormal IgA and other antibodies form clusters that build up in the small filters of the kidneys, which leads to inflammation and damage. Felzartamab is designed to target certain immune cells that produce these abnormal antibodies. This study will focus on participants who have protein in their urine (proteinuria) as a result of damaged kidneys. The main goal of the study is to learn about the effect felzartamab has on proteinuria. The main question that researchers want to answer is: • How much does the amount of protein in the urine change from the start of the study to Week 36? Researchers will learn about the effect felzartamab has on the kidneys' ability to filter blood. They will also learn more about the safety of felzartamab and how it is processed by the body. The study will be done as follows: * Participants will be screened to check if they can join the study. * Participants will be randomized to receive either felzartamab or a placebo. A placebo looks like the study drug but contains no real medicine. * Neither the researchers nor the participants will know what the participants will receive. * Participants will receive felzartamab or placebo as intravenous (IV) infusions. The treatment period will last 24 weeks. * Afterwards, participants will enter a follow-up period which will last 80 weeks. * In total, participants will have 17 study visits. Participants will stay in the study for about 2 years.

This is a 36-month, long-term, multicenter, observational study designed to describe the real world effectiveness of pegcetacoplan in patients with PNH. Patients meeting the eligibility criteria will be enrolled in the study and followed prospectively for approximately 36 months. Patient data will be collected from start of pegcetacoplan treatment to end of follow-up. Retrospective data on pegcetacoplan will be captured from the time of pegcetacoplan treatment initiation. Pegcetacoplan treatment data will be collected for a minimum of approximately 36 months and up to a maximum of approximately 72 months, including retrospective period depending on when the patient started pegcetacoplan treatment. After pegcetacoplan treatment discontinuation, patients will remain in the study for 8 weeks to capture any AEs. The scope of the study is to collect both retrospective and prospective data. Baseline is defined as start of pegcetacoplan treatment. The main part of the study will be prospective,collecting data on effectiveness, safety (all AEs), patient- and clinician-reported outcomes and health care resource use.

Study B7841007 is an open-label extension study to assess the long-term safety, tolerability, and efficacy of prophylaxis treatment with marstacimab in participants who did not require "Early Termination" from the Phase 3 Study B7841005 and from the Phase 3 Study B7841008. Study B7841005: approximately 145 adolescent and adult participants 12 to \<75 years of age with severe hemophilia A or moderately severe to severe hemophilia B (defined as FVIII activity \<1% or FIX activity ≤2%, respectively) with or without inhibitors are expected to be enrolled in Study B7841005 during which they will receive prophylaxis (defined as treatment by SC injection of marstacimab). Study B7841008: this is an ongoing Phase 3, open-label study in pediatric participants \<18 years of age with severe hemophilia A (FVIII Coagulation Factor Activity \<1%) or moderately severe to severe hemophilia B (FIX Coagulation Factor Activity ≤2%). A sequential approach will be used in enrolling at least 100 pediatric participants, at least 20 of which will be aged ≥12 to \<18 years and at least 80 participants will be aged ≥1 to \<12 years. At the start of study B7841008, the dosing and data available in adolescent and adult participants in Study B7841005 supported the initiation of B7841008 study in participants aged ≥12 to \<18 years. Subsequently, additional safety and efficacy data from adolescent participants in Study B7841005 became available for benefit/risk assessment in support of dosing participants aged ≥6 to \<12 years. Based on the positive benefit/risk assessment conducted by both internal Pfizer review and eDMC review, dosing of the ≥6 to \<12 years age group was initiated in June 2023 in B7841008 Study. Data from participants ≥6 years from B7841008 Study and Study B7841005 will support the dosing of participants aged ≥1 to \<6 years. All participants will be provided the prefilled pen (PFP) for administration of marstacimab in the study. Use of the prefilled syringe (PFS) will be permitted at the investigator's discretion for those participants who have difficulty with administration of the PFP. Additionally, participants will be provided the PFS for use in this study in countries where the PFS is anticipated to be the only presentation available commercially. An optional, open-label, single arm, substudy using the PFP was completed in the first 23 participants rolled over from Study B7841005 who agreed to participate in the substudy.

The purpose of this study is to learn about the study medicine called elranatamab.This study aims to compare elranatamab to other medicines for the treatment of MM (a type of cancer). This study is seeking participants who: * Are 18 years of age or older and have MM. * Have received treatments before for MM. * Have MM that has returned or not responded to their most recent treatment. Half of the participants will receive elranatamab. The other half of participants will receive a combination therapy selected by the study doctor. The selected combination therapy will include 2 to 3 different medicines commonly used to treat MM. Elranatamab will be given as a shot under the skin at the study clinic about once a week. This may change to a smaller number of shots later in the study. The medicines in the combination therapy will be taken by mouth (at home or at the study clinic) AND will be given either as: * a shot under the skin at the study clinic * through a needle in the vein at the study clinic The number of times these medicines will be taken depends on what combination therapy the study doctor selects. Participants may continue to receive elranatamab or a combination therapy until their MM is no longer responding. The study team will see how each participant is doing with the study treatment during regular visits at the study clinic. The study team will continue to follow-up with participants after study treatment with telephone contacts (or visits). The study will compare the experiences of people receiving elranatamab to those people receiving a combination therapy. This will help learn about the safety and how effective elranatamab is.
