Active clinical trials for "Hematologic Neoplasms"

Background: Many advances have been made in cancer treatments, but more research is needed. Comparing samples of cancerous tissue to samples of normal, noncancerous tissues may help find differences between them. These differences may help researchers find new ways to treat cancer. Objective: To collect tissues and blood samples from people with known or suspected cancer. The samples will be used to help identify new targets for cancer treatments. Eligibility: People aged 18 years and older with a known or suspected cancer that requires surgery or biopsy. Design: Participants will be screened. They will answer questions about their health. They can do this on the phone or in person. Researchers will collect information from participants medical records. Data may include information about any prior or current cancers. Data about other medical conditions may also be collected. Participants will have blood drawn. Some of the blood will be tested for HIV and hepatitis B and C. Some of the blood will be used for genetic research. Participants will have tissue samples collected during surgeries or biopsies. These are procedures the participants would have had as part of their standard care. No new procedures will be done just for this study. Researchers may also seek out samples from prior procedures the participant had done. Participants will remain in the study for 6 months. They may have blood drawn again. Researchers may also collect tissue samples from any procedures performed during that time.

Study purpose: to explore the entire spectrum of proteomic and genomic changes (amongst others) involved in diseases and in healthy/control populations. The Study is designed to discover biomarkers, develop and validate diagnostic assays, instruments and therapeutics as well as other medical research. Specifically, researchers may analyze proteins, RNA, DNA copy number changes, including large and small (1,000-100,000 kb) scale rearrangements, transcription profiles, epigenetic modifications, sequence variation, and sequence in both diseased tissue and case-matched germline DNA from Subjects.

The purpose of this study is to determine if recipients of non-myeloablative ex-vivo T-cell depleted peripheral blood (PBSC) stem cell transplantation using a mismatched related donor will have less severe graft versus host disease (GVHD), transplant related mortality, and less graft failure compared to alternative haploidentical stem cell transplantation.

The purpose of this study is to develop a standard of care treatment using allogeneic stem cells for patients with cancers of the blood. The protocol was revised to reflect that this study is considered "treatment guidelines", rather than a research study.

This clinical trial examines early enteral nutrition for patients undergoing donor stem cell transplantation for hematological malignancies. Patients undergoing donor stem cell transplantation often develop oral and gastrointestinal damage from chemotherapy, radiotherapy, or graft-versus-host disease that makes oral intake inadequate for meeting nutritional needs, especially during the catabolic period of recovery. Parenteral (intravenous) nutrition often requires a large fluid load, has been associated with increased risk of infection, can be associated with metabolic complications such as hyperglycemia and hypertriglyceridemia, is linked to elevated liver function tests, and may deprive the gastrointestinal mucosa of factors thought to promote mucosal integrity and healing. Enteral nutrition via a nasoenteric feeding tube is an alternate method of nutrition support. Giving early enteral nutrition may be more tolerable for patients undergoing a stem cell transplant.

Current protocols use G-CSF to mobilize hematopoietic progenitor cells from matched sibling and volunteer unrelated donors. Unfortunately, this process requires four to six days of G-CSF injection and can be associated with side effects, most notably bone pain and rarely splenic rupture. BL-8040 is given as a single SC injection, and collection of cells occurs on the same day as BL-8040 administration. This study will evaluate the safety and efficacy of this novel agent for hematopoietic progenitor cell mobilization and allogeneic transplantation based on the following hypotheses: Healthy HLA-matched donors receiving one injection of BL-8040 will mobilize sufficient CD34+ cells (at least 2.0 x 10^6 CD34+ cells/kg recipient weight) following no more than two leukapheresis collections to support a hematopoietic cell transplant. The hematopoietic cells mobilized by SC BL-8040 will be functional and will result in prompt and durable hematopoietic engraftment following transplantation into HLA-identical siblings with advanced hematological malignancies using various non-myeloablative and myeloablative conditioning regimens and regimens for routine GVHD prophylaxis. If these hypotheses 1 and 2 are confirmed after an interim safety analysis of the data, then the study will continue and include recruitment of haploidentical donors.

This was a long-term, continued treatment study that evaluated the long-term safety, clinical activity, and overall survival (OS) of duvelisib in individuals with hematologic malignancies that were previously treated with duvelisib in a previous sponsor-approved study.

Aim: to observe the graft versus tumor effect of Pegylated Interferonα-2b in patients with hematological malignancies relapsed after allogeneic hematopoietic stem cell transplantation (alloHSCT) Patients: patients relapsed after alloHSCT, men and women aged 14-60 years, without vital organ dysfunction or ongoing graft-verus-host disease (GVHD). Number of subjects: 50, Single center, one group, prospective. Drug: pegylated interferon alpha-2b (Peg Intron®; Schering-Plough) 1~1.5ug/kg qw, until occurrence of grade II or higher grade of acute GVHD, or no response to treatment after 8 doses of treatments.

This is an open-label, Phase I, dose-escalation study to determine the maximum tolerated dose (MTD) and/or recommended phase two dose (RPTD), and evaluate the safety, efficacy, and pharmacokinetic (PK) profile of ABBV-621 for participants with previously-treated solid tumors or hematologic malignancies. Only chemotherapy combination (ABBV-621 + FOLFIRI) enrolling participants with RAS-mutant CRC who have received one prior line of therapy is open for enrollment.
