Filter by:A randomized trial to assess the safety and effectiveness of the Colovac in providing temporary protection of the anastomosis in subjects undergoing lower anterior resection for colorectal cancer.
This is a single center, open-label, nonrandomized, Phase 1b, dose-escalation study designed to determine maximum tolerated dose (MTD) of CKD-516 in combination with durvalumab and evaluate the safety and tolerability profile, efficacy of CKD-516 and durvalumab treatment.
This is an open-label, multicenter, first in human, Phase 1a/1b study of PY314 in subjects with locally advanced (unresectable) and/or metastatic solid tumors that are refractory or relapsed to standard of care (including pembrolizumab, if approved for that indication).
This is an open-label, multicenter, First-In-Human (FIH), Phase 1a/1b study of PY159 in subjects with locally advanced (unresectable) and/or metastatic solid tumors that are refractory or relapsed to Standard Of Care (including Checkpoint Inhibitors, if approved for that indication).
One tricky aspect of the recommendations for colonoscopy prep is diet. This has a significant impact on the experience of the patient or participant in the screening program and, on the other hand, low adherence has been found in some studies despite a potential Hawthorne effect . It is noteworthy that despite its impact on patient experience, it is an area for which little evidence is available, which is why the guidelines give low-quality recommendations and there is probably considerable variability in clinical practice . In the early days of colonoscopy, a liquid diet for 48 hours was mainly recommended, although some centers indicated a low-residue diet or even the commercially available NASA astronaut diet. Later, the indication for a liquid diet was consolidated until finally numerous studies were published in favor of a low-residue diet, managing to increase tolerance and the quality of the preparation . A limitation of the preparation studies must be borne in mind that the colon cleansing rating scales were not introduced until 1999 when the Aronchick scale was published. Although there is solid evidence in favor of a low-residue diet versus a liquid diet, the investigators do not have evidence on how many days of a low-residue diet should be recommended, and this is reflected in the ESGE (European Society of Gastrointestinal Endoscopy) and ASGE (American Society of Gastrointestinal Endoscopy) guidelines . A randomized clinical trial comparing 3 days versus 1 day of a low residue diet has recently been published . There were no statistically significant differences in the rate of adequate preparations (82.7% vs. 85.6% OR 1.2 95% IC 0.72 to 2.15). However, this study has limited statistical power and a design that allows a non-inferiority analysis has not been followed. In relation to this, our research group is finalizing a non-inferiority clinical trial in whose intermediate analysis, with 421 participants, the non-inferiority of 1 day of diet is fulfilled (rate of poor preparation in 1 day 0.95% vs. 4.74% in 3 days; d + 5%, difference -3.78% IC -6.88% to -1.12%) (38). It is likely, taking into account the available evidence and its evolution, that diet plays a secondary role in preparation. Although no studies designed to directly assess this have been conducted, the research group has indirect data. Walter et al, under the hypothesis that the impact of the fractional preparation and the new preparations on the preparation diminished the importance of the diet, conducted a non-inferiority clinical trial between 2012 and 2013 in which they randomized the patients to follow a diet liquid versus low residue for one day and fractional preparation with Moviprep (39). They established a non-inferiority margin of -13.5%. Their results show a rate of good preparation (Boston> 5) in 68/72 (94.4%) in a liquid diet compared to 60/68 (88.2%) in a low-residue diet (p = 0.04) with a difference of -5.08% demonstrating non-inferiority of the low residue diet.
Investigators propose a retrospective cohort study to examine the impact of radiation therapy on the global pelvic floor function of women who have completed the immediate surveillance period for colorectal cancer
This is an open, single arm, multicenter phase 2 trial in which BO-112 will be administered intratumorally in combination with intravenous pembrolizumab in patients with liver metastasis from colorectal, gastric or gastroesophageal junction cancers. The objective is to reverse the primary resistance that a subgroup of patients from these tumors having microsatellite stability present to the PD-1 inhibitors. Treatment will be administered every 3 weeks, with the exception of the first cycle, in which BO-112 will be also administered on D8, for up to 2 years. The primary objective is overall response rate based on RECIST 1.1 and safety, specifically referred to treatment emergent adverse events (TEAEs) with severity ≥ Grade 3 related to the study treatment (NCI-CTCAE v 5.0). The secondary endpoints include other efficacy endpoints (duration of response, disease control rate, progression-free survival, overall survival at 6 months, all based on RECIST 1.1, and overall response rate based on a specific tumor assessment criteria to evaluate the response to immunotherapies, IRECIST) and safety, in this case considering the number and proportion of subjects with treatment TEAEs (any grade) . In addition, the changes in the tumor microenvironment induced by the injection of BO-112 will be also evaluated as exploratory endpoints.
This is a first-in-human, open-label, multi-center, Phase 1/2, dose-escalation study with expansion cohorts to evaluate NM21-1480 for safety and immunogenicity, to determine the maximal tolerated dose and recommended Phase 2 dose, define the pharmacokinetics, to explore the pharmacodynamics, and to obtain preliminary evidence of the clinical activity in adult patients with selected advanced solid tumors.
ATRC-101-A01 is a Phase 1b, open-label dose escalation and expansion trial of ATRC-101, an engineered fully human immunoglobulin G, subclass 1 (IgG1) antibody derived from a naturally occurring human antibody. The safety, tolerability, PK, and biological activity of ATRC-101 will be characterized when administered every two weeks (Q2W) or every 3 weeks (Q3W) as a monotherapy or in combination with other anticancer agents.
This is a Phase 2, open-label, multicenter study whose principal objectives are to evaluate the efficacy and safety/tolerability of poziotinib in five cohorts of 30 previously-treated patients each.
