Filter by:Multiple endocrine neoplasia type 2A (MEN2A) is a rare syndrome associated with activating mutations in the RET proto-oncogene, combining medullary thyroid cancer in approximately 100% of cases and pheochromocytoma in 10-80% of cases. While it is accepted that the RET mutation causes variable penetrance of pheochromocytoma in the MEN2A patient population, there is no pathophysiological explanation for the phenotypic variability among patients with the same mutation, including within the same family. The aim of this study is to better characterise the genetic factors that may explain the variable penetrance of pheochromocytoma in MEN2. To this end, the investigatoes plan to perform a whole exome analysis in 2 families carrying the p. Cys634Arg mutation causing NEM2A, followed in Marseille by the principal investigator: the 1st family has 11 members all aged over 35 years, for which 8 are carriers of pheochromocytoma while 3 have not developed it (while their age is higher than the latest age of diagnosis of pheochromocytoma in this family); the 2nd family has 3 members (father and daughter with pheochromocytoma developed before 25 years; son without pheochromocytoma at an age of 42 years). The investigators believe that the analysis of these patients should allow the isolation of variants on genes potentially involved in the genesis of a pheochromocytoma in MEN2.
T-1301 is a novel small-molecule inhibitor of multiple kinases being developed as an oral drug for the treatment of advanced solid tumors. The nonclinical study results demonstrate the nonclinical efficacy and safety of T-1301 and support the design of this Phase 1, first-in-human (FIH) clinical trial in subjects with advanced cancer. This study is an open-label, multi-center, Phase I dose-escalation study to evaluate the safety, tolerability, and pharmacokinetics of T-1301 capsules in subjects with advanced solid tumors (including lymphoma), and to identify the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D). Approximately 30 patients will be enrolled for the dose-escalation phase. Actual number of patients will be determined by the number of dose cohorts until the MTD is reached. T-1301 will be administered orally QD or BID in a 28-day cycle (21 days on treatment followed by 7 days off treatment) in sequential cohorts. Subjects can continue with the treatment until one of the discontinuation criteria is met or until the planned stop of the study (12 months after the last subject receives the first dose of study drug), whichever comes first. The planned dose levels are: 10, 20, 40, 60, 80, 100, 120, 140 and 160 mg/day. The dosing schedule will be once daily (QD) at the first dose level (10 mg/day) and be changed to twice daily (BID) starting with the second dose level. Other dose levels or dosing frequency may be explored based on safety and related drug exposure data following the decision of Safety Review Committee. The dose escalation will follow accelerated titration and the Bayesian optimal interval (BOIN) design. During the initial accelerated titration phase, one (1) subject is enrolled per dose level. In the subsequent phase when the BOIN design is used, subjects will be enrolled in cohorts of size 3-6.
A phase I dose escalation and cohort expansion study to evaluate the safety, tolerance and pharmacokinetic of BAT1308 injection in patients with advanced solid tumors
This study is open to adults with different types of advanced cancer (solid tumors) that are accessible for injection and/or biopsy. This study is for people for whom previous treatment was not successful or no treatment exists. The purpose of this study is to find the highest dose of a medicine called BI 1831169 that people with advanced cancer can tolerate when taken with or without ezabenlimab. Another purpose is to see whether BI 1831169 can fight cancer. BI 1831169 and ezabenlimab are medicines that may help the immune system fight cancer. In this study, BI 1831169 is given to people for the first time. This study has 2 parts. In Part 1, participants get BI 1831169 alone for up to 3 months. In Part 2, participants get BI 1831169 in combination with ezabenlimab. Participants who take the combination treatment get BI 1831169 for up to 3 months and ezabenlimab for up to 1 year. BI 1831169 is given as an injection into the tumor, or as an infusion into the vein, or both (injection and infusion). Ezabenlimab is given as an infusion into a vein. Participants get the medicines about every 3 weeks. This is called a treatment cycle. Participants visit the site study site regularly. The number of study visits vary based on the study phase and treatment response. Some visits include an overnight stay. The doctors regularly check the participants' health and monitor the tumors. The doctors also take note of any health problems that could have been caused by BI 1831169 or ezabenlimab.
This was a single-arm, prospective study to investigate the safety of cetuximab in combination with trifluridin tipiracil (TAS-102) in the third-line treatment of Chinese patients with RAS wild-type mCRC.
Flonoltinib Maleate (FM) targets Janus kinase 2 (JAK2) and FMS-like tyrosine kinase 3 (FLT3). FM is a dual target inhibitor of JAK2/FLT3.FM has the activity of inhibiting JAK2 signaling pathway, and pharmacodynamics evaluation also confirmed that FM has a good therapeutic effect on the primary splenomegaly model of mice induced by JAK2V617 mutation.Therefore, FM has the potential to treat bone marrow proliferative tumors.The drug is intended to be used in patients with MPN, mainly including medium-risk or high-risk myelofibrosis (FM) (including primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (PostPV-MF) and post-primary thrombocythemia myelofibrosis (postET-MF)), Polycythemia vera (PV) and essential thrombocythemia (ET) were the primary causes of thrombocythemia and thrombocythemia. FM has high inhibitory activity against JAK family and FLT3 kinase, suggesting that FM may have a certain therapeutic effect on AML disease.The IC50 of JAK2 kinase inhibition by FM was as low as 0.8 nM, while the IC50 of JAK1, JAK3 and Tyk2 kinase inhibition was 690 nM, 557 nM and 65nM, respectively. The selectivity of JAK2 kinase inhibition by FM was 862.5, 696.3 and 81.3 times, respectively. Therefore, FM showed highly selective inhibition of JAK2 kinase.The IC50 for FLT3 kinase was 15 nM. FM has better inhibitory activity against JAK2 kinase than the listed Ruxolitinib and Fedratinib, and has better selectivity against JAK family.In order to determine whether FM has targets other than JAK2 and Flt3 kinases, we tested FM's inhibitory activity against 100 human kinases that are highly associated with tumors, including some common drug-resistant mutant kinases.The results showed that, except for CDK4/6, LCK and LN, FM had no obvious inhibitory activity against the screened kinases at 0.1 μm, and no other targets were found. In vitro experiments on the proliferation of JAK2-dependent and Flt3-related tumor cell lines with FM showed that the tumor cell lines had a significant inhibitory effect. The IC50 of half of the tumor cell lines was less than 0.5 μm, which was better than or equal to the similar drugs Ruxolitinib and Fedratinib. The effect of FM on tumor cells from MPN patients indicated that FM has the potential to treat MPN disease. In multiple animal models of bone marrow proliferative tumors with JAK2V617F mutations, FM showed superior efficacy and low toxicity (no obvious VISCAL toxicity) than existing drugs on the market, and the tumor inhibition effect of FM showed a good dose-dependent relationship. Objectives of Study Main Purpose: 1. Tolerance and safety of flonoltinib maleate Tablets tablets in patients with bone marrow proliferative tumors; 2. To observe the possible dose-limiting toxicity(DLT) of flonoltinib maleate tablets in patients with bone marrow proliferative tumors,To determine the maximum tolerated dose(MTD) of flonoltinib maleate tablets,To provide the basis for the recommended dose and design scheme of the later clinical trial. Secondary Purpose: 1. To evaluate the pharmacokinetic characteristics of single and repeated oral administration of flonoltinib maleate tablets in patients with bone marrow proliferative tumors; 2. To evaluate the primary efficacy of single and multiple oral flonoltinib maleate tablets in patients with bone marrow proliferative tumors.
The goal of this study is to assess whether using PTeye (AiBiomed, Santa Barbara, CA) - a NIRAF detection modality - can improve patient outcomes and reduce healthcare associated costs after parathyroid surgeries. By being able to quickly and definitively locate parathyroid glands while in the operating room, the duration of surgical procedure could be further reduced. In addition, the number of frozen section biopsy and associated costs can be minimized. Furthermore, repeat surgeries as a result of missing a diseased parathyroid gland at the time of the initial parathyroidectomy for hyperparathyroidism could potentially be avoided.
This trial is a prospective, randomized (1:1 ratio), multicenter, comparative and phase II study, conducted in patients with unresectable advanced gastrointestinal stromal tumors (GIST) after failure of imatinib (disease progression),sunitinib and regorafenib (either disease progression or intolerance) In the first arm, patients will be treated with imatinib + atezolizumab (experimental arm), whereas in the second arm, patients will be treated with imatinib alone (control arm). The comparison between this two arms will allow to compare whether or not atezolizumab and imatinib is efficient for disease control, in terms of Progression-Free Survival improvement.
