There are about 2656 clinical studies being (or have been) conducted in Puerto Rico. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to assess the safety and effectiveness of nivolumab with docetaxel in men with advanced castration resistant prostate cancer who have progressed after second-generation hormonal manipulation.
This phase III trial studies how well letrozole with or without paclitaxel and carboplatin works in treating patients with stage II-IV low-grade serous carcinoma of the ovary, fallopian tube, or peritoneum. Letrozole is an enzyme inhibitor that lowers the amount of estrogen made by the body which in turn may stop the growth of tumor cells that need estrogen to grow. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving letrozole alone or in combination with paclitaxel and carboplatin works better in treating patients with low-grade serous carcinoma of the ovary, fallopian tube, or peritoneum compared to paclitaxel and carboplatin without letrozole.
This phase III trial studies how well vitamin D3 given with standard chemotherapy and bevacizumab works in treating patients with colorectal cancer that has spread to other parts of the body. Vitamin D3 helps the body use calcium and phosphorus to make strong bones and teeth. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, oxaliplatin, and irinotecan hydrochloride, work in different ways to stop the growth of tumor cells by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as bevacizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving vitamin D3 with chemotherapy and bevacizumab may work better in shrinking or stabilizing colorectal cancer. It is not yet known whether giving high-dose vitamin D3 in addition to chemotherapy and bevacizumab would extend patients' time without disease compared to the usual approach (chemotherapy and bevacizumab).
A Randomized, Double-Blind, Vehicle-Controlled, Multicenter Study to Assess the Efficacy and Safety of Methyl aminolevulinate hydrochloride (MAL) 16.8% cream (CD06809-41) versus vehicle cream in the treatment of thin and moderately thick, non-hyperkeratotic, non-pigmented actinic keratosis of the face and scalp when using daylight photodynamic therapy (DL-PDT).
Primary Objective: To demonstrate the vaccine seroresponse sufficiency of meningococcal serogroups A, C, Y, and W following the administration of a booster dose of meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine: - In Group 1 participants who were first vaccinated with 1 dose of MenACYW Conjugate vaccine 3-6 years before the booster dose. - In Group 2 participants who were first vaccinated with 1 dose of Menveo vaccine (meningococcal [Groups A, C, Y and W135] Oligosaccharide Diphtheria CRM197 Conjugate vaccine) 3-6 years before the booster dose. Secondary Objective: To describe: - The vaccine seroresponse, seroprotection (serum bactericidal assay using human complement [hSBA] titer greater than or equal to [>=]1:8), and antibody responses (geometric mean titers [GMTs]) of meningococcal serogroups A, C, Y, and W measured using hSBA in serum specimens collected 6 days (±1 day) after vaccination in a subset of 50 participants per group (Groups 1 and 2). - The vaccine seroresponse, seroprotection (hSBA titer >=1:8), and antibody responses (GMTs) to serogroups A, C, Y, and W measured using hSBA on Day (D)0 (pre-vaccination) and D30 (+14 days) after vaccination with MenACYW Conjugate vaccine alone (Groups 1 and 2). - The antibody persistence (GMTs and vaccine seroprotection; hSBA titer >=1:8) of meningococcal serogroups A, C, Y, and W before a booster dose in participants who received either MenACYW Conjugate vaccine or Menveo vaccine 3-6 years earlier. - The antibody persistence (GMTs and vaccine seroprotection; hSBA titer >=1:8) of meningococcal serogroups A, C, Y, and W in participants who received either a single dose MenACYW Conjugate vaccine (participants randomized to MET59 Groups 1, 3, and 4) or Menveo vaccine (participants assigned to MET59 Group 2), as part of study MET50, or MET43 (participants randomized to MET59 Groups 1, 3 and 4). - To describe the vaccine seroresponse, seroprotection (hSBA titer >=1:8), and antibody responses (GMTs) to the antigens present in MenACYW Conjugate vaccine, when MenACYW Conjugate vaccine was given concomitantly with meningococcal serogroup B (MenB) vaccine (Groups 3 and 4), compared to those when it was given alone (Group 1).
The purpose of this study is to confirm the tolerability of recommended Phase 2 dose (RP2D) of Lazertinib (Phase 1), to determine the tolerability and identify the recommended Phase 2 combination dose of Lazertinib when combined with Amivantamab (JNJ-61186372) (Phase 1b), to characterize the safety and tolerability of Lazertinib and Amivantamab combinations at the RP2CD in participants with advanced non-small cell lung cancer (NSCLC) with documented advanced or metastatic epidermal growth factor receptor (EGFR) mutation (Phase 1b expansion cohorts A, B, C, D and E), to estimate the antitumor activity of Lazertinib and Amivantamab combinations at the RP2CD in participants with advanced NSCLC with documented advanced or metastatic EGFR mutation (Phase 1b expansion cohorts A, B, C, and D), to validate the biomarker identified in Phase 1b expansion Cohort D as a predictor of antitumor activity of Lazertinib and Amivantamab combination (Cohort E) or Amivantamab monotherapy (Cohort F) in participants with osimertinib-relapsed, chemotherapy-naïve, EGFR Exon19del or L858R mutated NSCLC, to identify the recommended Phase 2 dose (RP2ChD) of Lazertinib when combined with Amivantamab and standard of care chemotherapy and to determine the tolerability of the Lazertinib, Amivantamab, and platinum-doublet chemotherapy (LACP) combination (Phase 1b LACP combination cohort) and to characterize the safety and tolerability of Lazertinib at the RP2ChD and Amivantamab and standard of care chemotherapy in participants with advanced or metastatic EGFR-mutated NSCLC (Phase 1b LACP combination cohort), to assess 2 potential biomarker strategies to identify participants at increased, or decreased, probability of tumor response with JNJ-61186372 and lazertinib combination in participants with EGFR Exon19del or L858R mutated NSCLC progressed on or after osimertinib (Phase 1b expansion Cohort D).
A randomized multi-arm study evaluating the safety and efficacy of palbociclib and anastrozole with or without nivolumab in participants with ER+/HER2- breast cancer
This phase II/III trial studies how well circulating tumor deoxyribonucleic acid (ctDNA) testing in the blood works in predicting treatment for patients with stage IIA colon cancer after surgery. ctDNA are circulating tumor cells that are shed by tumors into the blood. Finding ctDNA in the blood means that there is very likely some small amounts of cancer that remain after surgery. However, this cancer, if detected, cannot be found on other tests usually used to find cancer, as it is too small. Testing for ctDNA levels may help identify patients with colon cancer after surgery who do benefit, and those who do not benefit, from receiving chemotherapy.
