This research investigates the use of autologous tooth root slices combined with collagen plugs and vitamin D3 treatment during alveolar ridge preservation surgery following tooth extraction. The study aims to evaluate whether this combination can increase the bone formation rate in the extraction socket and improve healing compared to traditional methods. The trial explores how these materials affect the stability and regeneration of bone, using advanced 2D and 3D imaging techniques to monitor changes. Participants receive treatment involving placement of autologous tooth root slices made from their own extracted teeth into the extraction socket, along with a collagen plug carrying vitamin D3 applied to the lower two-thirds to one-half of the socket. Bone graft materials may be used as needed to support the area. A skin flap created by flap surgery covers the autologous tooth root slices to help stabilize them and promote wound healing, aiming to reduce contamination and improve closure. Throughout the study, participants undergo various assessments including 3D computed tomography scans, periapical X-rays, intraoral scanner measurements, and resonance frequency analysis to evaluate implant stability. These evaluations occur at baseline, between weeks 12 to 16, and up to 24 weeks after tooth extraction. The study tracks bone regeneration, wound healing, and the stability of the autologous tooth root covers to understand the effectiveness of this new medical technology over time.

Researchers are evaluating the use of 68Ga-PSMA PET/CT imaging to assess bone tumor burden in men with metastatic castration-resistant prostate cancer (mCRPC) who are receiving 223Ra-dichloride treatment. The study aims to compare the detection rates of disease progression between 68Ga-PSMA PET and traditional bone scans. Secondary goals include examining how PET tumor burden relates to blood markers like alkaline phosphatase and prostate-specific antigen levels. Participants will undergo PET/CT scans using a GE Discovery MI system after receiving an intravenous bolus of 2-5 mCi of 68Ga-PSMA-11. Scans are performed 60 minutes post-injection with specific imaging parameters detailed for consistency. Patients will have baseline PET/CT scans and then follow-up scans after their 3rd and 6th injections of 223Ra-dichloride. Each scan involves catheter placement and close monitoring, including EKG and lab tests before and after the first PET scan. During the study, patients will be observed for any adverse events after imaging and monitored through blood tests and clinical assessments. The primary outcome is the change in lesion detection by PET imaging at 9-11 weeks or 21-23 weeks. Experienced nuclear medicine physicians will interpret all images to determine diagnostic positivity. The total study duration includes multiple imaging sessions aligned with the radiopharmaceutical injections and safety evaluations.

Researchers are investigating whether Ga-68 PSMA PET/MRI scans can better diagnose prostate cancer compared to multiparametric MRI (mpMRI) in men aged 40 to 85 years old. These men have not had a prostate biopsy before but are suspected of having prostate cancer due to elevated prostate-specific antigen (PSA) levels or lower urinary tract symptoms. The study focuses on the accuracy of these imaging methods, especially looking at positive and negative predictive values and how matching lesion locations between PSMA PET and MRI might affect diagnosis. Participants will receive a Ga-68 PSMA PET/MRI scan and will be monitored for two years to see if prostate cancer is diagnosed. The study involves follow-up visits every six months where participants will have checkups and blood tests. This approach helps researchers compare the diagnostic effectiveness of PSMA PET/MRI with standard mpMRI over time. During the study, participants will be regularly evaluated through medical visits and blood tests every six months for two years. Researchers will measure how well the imaging tests predict the presence or absence of prostate cancer using specific scoring systems. Safety and health status will be monitored throughout the follow-up period to gather comprehensive data on diagnosis accuracy and participant well-being.

Researchers are evaluating the safety and effectiveness of rilzabrutinib compared to placebo in adults with active Immunoglobulin G4 Related Disease (IgG4-RD). This Phase 3, randomized, double-blind study aims to measure the time until the first IgG4-RD clinical disease flare during a 52-week treatment period. Additional goals include assessing disease control, flare-free rates, use of glucocorticoid rescue, and monitoring safety through adverse events, laboratory tests, and electrocardiograms. Participants will be randomly assigned to receive either oral rilzabrutinib tablets or placebo for 52 weeks. Glucocorticoids may be used as rescue medication if needed. The study includes a screening period lasting 4 to 6 weeks before treatment begins, followed by the 52-week double-blind treatment phase, and a 2-week follow-up after treatment. An optional open-label extension lasting up to 108 weeks is also available for participants. During the study, participants will attend 16 visits for assessments, which may include clinical evaluations, imaging tests such as CT, MRI, PET, or ultrasound to monitor disease activity, and laboratory tests. Researchers will track time to disease flare and collect data on flare-free rates, safety parameters, and medication use. Participants' vaccination status and contraceptive use will be monitored according to local guidelines, and overall study participation could last up to 60 weeks or longer if joining the extension phase.

Researchers are studying advanced renal cell carcinoma (RCC) that has returned after prior adjuvant therapy. The trial aims to find out if treatment with belzutifan and zanzalintinib helps patients live longer and delays disease progression compared to treatment with cabozantinib. This is a Phase 3 randomized study focusing on participants with recurrent advanced RCC who have previously received anti-PD-1/L1 therapy. Participants are randomly assigned to receive one of two oral drug regimens: either belzutifan combined with zanzalintinib, both taken once daily, or cabozantinib alone, also taken once daily. The study compares these treatments to assess their effects on disease control and overall survival. During the study, participants will be monitored for progression-free survival and overall survival for up to approximately 73 months. Researchers will evaluate how well the cancer responds to treatment and track any changes in health status over time. Safety and effectiveness of the treatments will be closely followed throughout the study period.

Researchers are evaluating new treatment options for adults with locally advanced or metastatic colorectal cancer that cannot be removed by surgery and has a specific KRAS G12C gene mutation. This study compares the safety and effectiveness of adding calderasib and cetuximab, both targeted therapies, to a standard chemotherapy regimen called mFOLFOX6. The goal is to see if this combination can help patients live longer without their cancer growing or spreading compared to current treatments that may include mFOLFOX6 with or without bevacizumab. The study has two parts. It involves treatment with calderasib taken as an oral tablet, cetuximab given according to standard procedures, and mFOLFOX6 chemotherapy combining oxaliplatin, leucovorin/levofolinate calcium, and 5-fluorouracil. Some participants may receive bevacizumab or a bevacizumab biosimilar as part of the comparison. The treatments are given following approved dosing schedules. This design allows researchers to assess the safety and tolerability of these drug combinations in treating this type of colorectal cancer with the KRAS G12C mutation. Participants will be monitored for side effects, treatment tolerability, and cancer progression over a period that may last up to about 44 months. Researchers will track outcomes such as how many participants experience dose-limiting toxicities or adverse events, how many stop treatment due to side effects, and progression-free survival time. Assessments include health evaluations, laboratory tests, and imaging to observe cancer status. This long-term follow-up aims to understand both safety and effectiveness of the treatment combinations.

Researchers are investigating sacituzumab tirumotecan (MK-2870) alone or combined with other treatments to treat certain gastrointestinal cancers. These include colorectal cancer that cannot be removed by surgery or has spread, advanced pancreatic ductal adenocarcinoma, and biliary tract cancer. The study aims to understand the safety and tolerability of sacituzumab tirumotecan and measure how many participants respond to the treatment by having their cancer shrink or disappear. Participants may receive sacituzumab tirumotecan by intravenous infusion alone or with other anticancer drugs such as fluorouracil (5-FU), leucovorin or levoleucovorin, cisplatin, and pembrolizumab. Rescue medications like diphenhydramine, H2 receptor antagonists, acetaminophen, dexamethasone, and a steroid mouthwash are given to prevent infusion reactions and oral side effects. Supportive care treatments for side effects, including antidiarrheal and antiemetic agents, are allowed throughout the study. During the study, researchers monitor participants for dose-limiting toxicities within about 4 weeks and track adverse events, treatment discontinuations, and tumor response over up to approximately 63 months. Assessments include safety evaluations and measuring cancer response using standardized criteria. This long-term follow-up helps evaluate both the effectiveness and safety of the treatments being studied.

Researchers are evaluating molnupiravir, a study medicine designed to stop the COVID-19 virus from multiplying, to see if it can prevent severe illness from COVID-19 more effectively than a placebo. This Phase 3 randomized, placebo-controlled, double-blind study focuses on non-hospitalized adults at high risk of severe disease progression due to COVID-19. The study addresses the need for alternative treatments for people who cannot take certain COVID-19 medications due to availability or potential drug interactions. Participants will receive either molnupiravir or a placebo, both given orally as two 400 mg film-coated tablets every 12 hours for 5 days, totaling 10 doses. Some participants may also receive remdesivir as part of standard care if clinically appropriate and available. The study compares the effects of molnupiravir with placebo in preventing severe illness outcomes. Throughout the study, participants will be monitored for outcomes such as hospitalization, death, or medically attended visits related to COVID-19 up to 29 days. Safety is assessed by tracking adverse events for up to about 5 months and discontinuation of study treatment due to adverse events for about 5 days. The study involves laboratory tests, symptom assessments, and safety evaluations to understand molnupiravir's impact on disease progression and participant health.

Researchers are investigating new treatments for metastatic cervical cancer, which is cancer that has spread from the cervix to other parts of the body. This Phase 3 study aims to evaluate the safety and effectiveness of combining sacituzumab tirumotecan (sac-TMT), an antibody drug that targets cancer cells, with pembrolizumab and bevacizumab. The study seeks to find out if this combination can help people live longer or keep their cancer from worsening compared to standard treatments. The study has two parts. In Part 1, participants receive sac-TMT together with pembrolizumab and bevacizumab to assess safety. In Part 2, after standard initial treatment, those whose cancer does not progress will be randomly assigned to maintenance treatment with either pembrolizumab alone or sac-TMT plus pembrolizumab. Bevacizumab may be added during maintenance treatment based on the doctor's decision. All treatments are given through intravenous infusions, and participants may receive rescue medications to manage side effects before sac-TMT infusion. Participants will be monitored for adverse events and treatment tolerability over several months. The study measures include progression-free survival and overall survival, assessed by independent review. Safety and treatment continuation rates are tracked during Part 1 for up to approximately 66-69 months, while Part 2 outcome measures extend up to 48-60 months. Various assessments, including laboratory tests and evaluations of cancer status, will be performed throughout the study to understand treatment effects and participant well-being.

Researchers are investigating new treatments for people with high-risk, early-stage breast cancer, specifically targeting triple-negative breast cancer (TNBC) and hormone receptor (HR)-low positive/HER2-negative breast cancer. These types have little or no HER2 protein and involve hormones like estrogen or progesterone. The study aims to evaluate if the addition of sacituzumab tirumotecan (sac-TMT), a targeted therapy, combined with pembrolizumab and chemotherapy can improve outcomes compared to pembrolizumab with chemotherapy alone. Participants receive treatments including sacituzumab tirumotecan, pembrolizumab, and chemotherapy drugs such as carboplatin and paclitaxel, all given by intravenous infusion. Rescue medications like antihistamines, acetaminophen, dexamethasone, or steroid mouthwash may be used as needed. The study is randomized and open-label, comparing sac-TMT followed by chemotherapy plus pembrolizumab to chemotherapy and pembrolizumab without sac-TMT. During the study, researchers will monitor participants up to about 30 weeks to assess the percentage of people with no remaining cancer cells at surgery. They will also follow participants for up to approximately 92 months to track event-free survival, meaning time without cancer growth, spread, or return. Participants will undergo imaging, clinical assessments, and laboratory tests to evaluate treatment effects and safety throughout the study.
