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.

A study to evaluate the effect of abelacimab relative to placebo on the rate of ischemic stroke or systemic embolism (SE) in patients with Atrial Fibrillation (AF) who have been deemed by their responsible physicians or by their own decision to be unsuitable for oral anticoagulation therapy.

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 study is to evaluate whether zilebesiran versus placebo reduces the risk of cardiovascular (CV) death, nonfatal myocardial infarction (MI), nonfatal stroke, or heart failure (HF) events. This is an event-driven study that will continue until the targeted number of positively adjudicated primary endpoint clinical outcome events (COEs) have been reached.

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).

The purpose of this phase 3, randomized, placebo controlled, event-driven study is to assess the effect of AZD0780, an oral PCSK9 inhibitor, compared with placebo in reducing the risk of MACE-PLUS in patients with established ASCVD or at high risk for a first ASCVD event. The effect of AZD0780 vs placebo on the risk of MACE-PLUS will be evaluated from randomisation until the primary analysis censoring date (PACD). The Study Closure Visit will be scheduled to occur after the PACD and will be the final visit for each participant in the study.

This Phase III, multicenter, double-blind, placebo-controlled treat-through study will evaluate the efficacy and safety of induction and maintenance therapy with Afimkibart (also known as RO7790121) in participants with moderately to severely active Crohn's disease (CD).

This Phase III, multicenter, double-blind, placebo-controlled study will evaluate the efficacy and safety of induction therapy with Afimkibart (RO7790121) compared with placebo in participants with moderately to severely active ulcerative colitis (UC).

The aim of this study is to compare progression free survival (PFS) in treatment-naïve participants with KRAS p.G12C mutated metastatic colorectal cancer (mCRC) receiving sotorasib, panitumumab and FOLFIRI vs FOLFIRI with or without bevacizumab-awwb.

The participants of this study will have confirmed Primary Biliary Cholangitis (PBC) and cirrhosis (scarring of the liver). PBC is a slowly progressive disease, characterised by damage to the bile ducts in the liver, leading to a build-up of bile acids which causes further damage. The liver damage in PBC may lead to cirrhosis. PBC may also be associated with multiple symptoms. Many patients with PBC may require liver transplant or may die if the disease progresses and a liver transplant is not done. This study will compare a daily dose of elafibranor (the study drug) to a daily dose of placebo (a dummy treatment) and will last up to 3.5 years for each participant. The main aim of this study is to determine if elafibranor is better than placebo in preventing clinical outcome events showing disease worsening (including progression of disease leading to liver transplant or death). This study will also study the safety of long-term treatment with elafibranor, as well as the impact on symptoms such as itching and tiredness.

This is a phase 3, global, multicenter, 2-part trial with a double-blind period and an open-label extension (OLE). The trial is event-driven, and Part 1 will conclude when approximately 850 primary endpoint events have occurred.

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.

This is a Phase 3, randomized, actively controlled, double-blinded, double-dummy, superiority study to evaluate the efficacy and safety of ibuzatrelvir alone and in combination with remdesivir IV compared to remdesivir IV alone for the treatment of symptomatic COVID-19 in severely immunocompromised adult participants who are non-hospitalized or are hospitalized for observation or study intervention administration but do not require supplemental oxygen for COVID-19.

Study to investigate the efficacy, safety and tolerability of systemic chemotherapy plus ponsegromab versus systemic chemotherapy plus placebo for the first-line treatment in adult participants with cachexia and metastatic pancreatic ductal adenocardinoma.

The purpose of the study is to evaluate whether ibuzatrelvir is effective and safe in adults and adolescents with COVID-19 who do not need to be in the hospital but who are at high risk for progression to severe disease. Eligible participants will be randomly assigned (by chance) to receive ibuzatrelvir or matching placebo orally for 5 days. Co-administration of locally available standard of care is allowed. The total duration of the study is around 6 months.

This study will explore whether a combination of the investigational drug PF-06821497 and enzalutamide will work better than taking enzalutamide alone in participants with mCRPC who are ARSi or abiraterone naïve.

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.

This study is being done to look at the effect and safety of different doses of NNC0662-0419 in people living with type 2 diabetes when compared to placebo or semaglutide. The purpose of this clinical study is to find out if NNC0662-0419 is effective and safe for treating people living with type 2 diabetes. Participants will get either NNC0662-0419, semaglutide or placebo. Which treatment participants get is decided by chance. NNC0662-0419 is a new medicine which cannot be prescribed by doctors but has previously been tested in humans. Semaglutide is an approved medication to treat type 2 diabetes.

This study will explore whether a combination of the investigational drug mevrometostat (PF-06821497) and enzalutamide will work better than taking enzalutamide alone in participants with mCSPC who are ARPI naïve and have not yet received chemotherapy in the mCSPC setting.

This is a Phase 2, multicenter, proof-of-concept platform study in adult participants with moderately to severely active ulcerative colitis (UC).
