Filter by:Background: - Research suggests that occupational exposure to formaldehyde is associated with increased risk for myeloid leukemia, but the significance of these findings is uncertain because of inconsistencies among studies and lack of knowledge of how formaldehyde can cause leukemia. - Damage to the DNA of myeloid cells (type of white blood cell) or an environmental factor not affecting the cell genetic machinery may be involved. Objective: To determine if formaldehyde exposure is associated with genetic or other changes in myeloid cells. Eligibility: Workers exposed to high levels of formaldehyde and unexposed workers in Guangdong Province, China. Design: - 40 exposed workers and 40 unexposed workers will be enrolled. - Subjects wear small instruments at work that measure chemicals in the air for 1 or 2 days. - Subjects have a brief physical examination and provide blood, urine, and mouth rinse samples. - Subjects answer a questionnaire about work, smoking and drinking, use of medicines, medical history, general health, exposure to radiation and exposure to various substances at home.
This is an open label, dose finding, phase Ib clinical trial to determine the maximum tolerated dose (MTD) and/or RP2D of the orally administered PI3K/mTOR inhibitor BEZ235 in combination with the MEK1/2 inhibitor MEK162. This combination will be explored in patients with EGFR mutant NSCLC which has progressed on EGFR inhibitors and triple negative breast cancer, as well as pancreatic cancer, colorectal cancer, malignant melanoma, NSCLC, and other advanced solid tumors with KRAS, NRAS, and/or BRAF mutations. Dose escalation will be guided by a Bayesian logistic regression model with overdose control. At MTD or RP2D, two expansion arms will be opened in order to further assess safety and preliminary anti-tumor activity of the combination of BEZ235 and MEK162. Study drugs will be administered orally on a continuous schedule, MEK162 bid and BEZ235 qd, a treatment cycle is defined as 28 days.
This is a phase 1b open-label study evaluating the preliminary safety and maximum tolerated dose of a new formulation of INNO-206 administered at doses of 230 mg/m2, 350 mg/m2 and 450 mg/m2 (165, 260, 325 mg/m2 doxorubicin equivalents, respectively) through intravenous infusion on Day 1 every 21 days for up to 6 cycles.
This is an Asian Phase 1, multi center, open label, single arm study of PF 03446962 with dose escalation and designed to define the Maximum Tolerated Dose [MTD] and the Recommended Phase 2 Dose [RP2D].
The primary objective of this trial is to determine the safety and tolerability of BI 853520 monotherapy by defining the maximum tolerated dose (MTD) and recommending the dose for further trials in the development of this compound. Secondary objectives are - determination of the pharmacokinetic (PK) profile; - exploratory pharmacodynamic analysis; and - collection of preliminary data on anti-tumour efficacy.
Clinical study to determine safety, tolerability, and maximum tolerated dose of BAY1000394 given in 4 week on / 2 week off schedule to patients with advanced solid tumors
The purpose of this study is to determine whether the tailored management of locally advanced rectal carcinoma can improve the oncologic and functional outcome.
This phase I pilot study aims to define the safety of a combined treatment of bevacizumab and whole brain radiation therapy for the treatment of patients with brain metastasis of solid tumors. If this therapeutic scheme confirms it's safety profile, the investigators can expect: - first, to allow that all patients can receive bevacizumab for their advanced and/or metastatic cancer if necessary, even in case of brain metastasis. - Secondly, if this trial confirm a synergic effect of the combination of angiogenesis inhibitors and brain radiotherapy for local control of brain metastasis, an improvement of the therapeutic results for these patients which have a poor hope of survival and for which none innovative approach is currently suggested. Moreover, the investigators hope that the analysis of the different data of MRI evaluation - morphological and functional - will allow better definition of radiological evaluation of the therapeutic effect of angiogenesis inhibitors on brain metastasis.
The best treatment for recurrent cancers or those that do not respond to therapies is not known. Typically, patients with these cancers receive a combination of cancer drugs (chemotherapy), surgery, or radiation therapy. These treatments can prolong their life but may not offer a long-term cure. This study proposes using a drug called Sirolimus in combination with common chemotherapy drugs to treat patients with recurrent and refractory solid tumors. Sirolimus has been found to inhibit cell growth and to have anti-tumor activity in pediatric solid tumors in previous studies and, therefore, has the potential to increase the effectiveness of the chemotherapy drugs when given together. This study wil investigate the highest dose of Sirolimus that can be given orally with other oral chemotherapy drugs. Cohorts of 2 subjects will be started at the minimum dose. The dose will be increased in the next 2 subjects as long as there were no major reactions in the previous groups. This study will also seek to learn more about the side effects of sirolimus when used in this combination and what effects the drug has on the white cells and the immune system. Successful use of this drug will impact the cancer population greatly by providing an increased chance of survival to those with resistant or recurrent cancers.
Background: - Urothelial cancer (tumors of the bladder, urethra, ureter, or renal pelvis) often responds initially to standard chemotherapy treatments, but frequently recurs and can often spread to other parts of the body. TRC105, an experimental drug that blocks the development of the new blood vessels needed for tumor growth, may be able to shrink or stabilize urothelial cancer tumors. TRC105 has been given previously to individuals with other types of cancer, and researchers are interested in determining its safety and effectiveness in treating urothelial cancer. Objectives: - To determine the safety and effectiveness of TRC105 as a treatment for metastatic urothelial cancer that has not responded to standard treatments. Eligibility: - Individuals at least 18 years of age who have been diagnosed with urothelial cancer that has spread to other parts of the body and has not responded to standard chemotherapy. Design: - Participants will be screened with a physical examination, medical history, blood tests, and tumor imaging studies. - Participants will receive TRC105 intravenously once every 2 weeks on days 1 and 15 of a 28-day treatment cycle. The first dose of TRC105 will be given over a 4-hour period; participants who do not have side effects may receive the next dose over 2 hours. If the second dose is tolerated, subsequent doses can be given over at least 1 hour. - To help prevent known side effects of TRC105, participants will take two doses (one in the morning and one in the evening) of the steroid dexamethasone on the day before each infusion is scheduled. Participants may have additional dexamethasone 30 minutes before infusion, and may have the infusion slowed or stopped to adjust for side effects. - Participants will be monitored with blood samples, physical examinations, and tumor imaging studies through the cycles of treatment. - Participants will continue to take TRC105 for as long as the treatment is effective against the cancer and as long as the side effects are not severe enough to stop treatment.
