Filter by:Some studies have shown that approximately 15% of patients with advanced hormone receptor (HR) positive breast cancer and 1/3 of triple negative breast cancer will develop brain metastasis. At present, there is no unified drug treatment standard for HER2-negative breast cancer brain metastasis (BCBM). The evidence of single traditional chemotherapy drug as the main treatment of brain metastasis is not sufficient. Some exploratory studies on HER2-negative BCBM have shown that the central nervous system objective response rate (CNS-ORR) of anti-angiogenic drugs combined with chemotherapy is around 55%-80%。 Adebrelimab (a humanized PD-L1 monoclonal antibody) specifically blocks the binding of PD-1 and PD-L1, terminates the immunosuppressive signal produced by T cells, and makes T cells re-recognize tumor cells and kill them, thereby inhibiting tumor growth. In China, Adebelizumab has been approved for using in combination with chemotherapy as a first-line treatment for extensive stage small cell lung cancer. Apatinib (a small molecule VEGFR tyrosine kinase inhibitor) mainly plays an anti-angiogenic effect in the treatment of malignant tumors by inhibiting VEGFR. Apatinib has been approved monotherapy for advanced gastric adenocarcinoma or gastroesophageal junction adenocarcinoma that has progressed or relapsed after at least two systematic chemotherapies, advanced liver cancer that has failed or is intolerable after at least first-line systematic treatment, and first-line treatment in patients with unresectable or metastatic hepatocellular carcinoma combined with camrelizumab. Due to the lack of effective drug therapy for HER2-negative BCBM, a variety of treatment combinations are still being explored. We hypothesized that adebrelimab plus apatinib and etoposide is an explorable and effective treatment for HER2- negative BCBM.
The purpose of this study is to determine whether cytoreduction of bulky metastatic disease using ultra high dose SBRT in combination with immunotherapy is tolerable and feasible In patients who have exhausted SoC treatment options.
Bone metastasis is a common disease of advanced tumors. It refers to the metastasis of malignant tumors originating in a certain organ to the bones through the blood circulation or lymphatic system. The incidence of bone metastasis in breast and prostate cancer is as high as 65%-75%. Bone metastasis of malignant tumors often leads to severe bone lesions, including bone pain, pathological fractures, spinal cord compression, hypercalcemia and other bone-related events (SRE). SRE caused by bone metastasis of tumors can greatly reduce the quality of life of tumor patients. In severe cases, it can lead to rapid deterioration of the condition or even death, which greatly affects the extension of the patient's survival period. ALMB-0168 is designed to activate Cx43 hemichannels, which release key anti-cancer factors (such as ATP) into the extracellular environment. In several mouse models of breast cancer bone metastasis and orthotopic osteosarcoma, ALMB-0168 dose-dependently inhibited tumor growth and was able to extend the lifespan of tumor-bearing animals, indicating its potential as a therapeutic drug for malignant bone tumors. . Clinical research data from China and Australia show that ALMB-0168 is safe and initially effective in patients with bone metastasis and osteosarcoma;
The purpose of this research study is to determine if lattice radiation therapy (LRT) will provide better treatment for bulky (large) tumors than current standard of care radiotherapy.
The main objective of this study is to test if adding the mistletoe extract Iscador® Qu to regular cancer treatment with immune checkpoint inhibitors affects: - The immune system's ability to fight cancer - Safety of the treatment - How well the treatment performs against cancer - How the patient feels during treatment Researchers will compare patients treated with immune checkpoint inhibitors plus Iscador® Qu with patients treated with imune checkpoint inhibitors only.
This study will evaluate whether the combination of sacituzumab govitecan (SG) and bevacizumab will result in shrinkage of brain metastases from patients with non-squamous non-small cell lung cancer (NSCLC), with disease progression on chemotherapy and immunotherapy.
Patients with end-stage kidney disease (ESKD) have an increased risk of cardiovascular mortality. High parathyroid hormone (PTH) from secondary hyperparathyroidism leads to increased efflux of phosphate and calcium from bone, which exacerbates vascular calcification and increases the risk of bone fractures. The main driving factor for secondary hyperparathyroidism is hypocalcaemia caused by low levels of 1,25-dihydroxy vitamin D and pharmacological supplementation with activated vitamin D and oral calcium-containing phosphate-binders are used to control secondary hyperparathyroidism. The amount of calcium used in this context is controversial, as higher calcium load in blood may theoretically increase vascular calcification. Conversely, by alleviating the efflux of phosphate and calcium from bone due to secondary hyperparathyroidism, increasing the load of calcium might actually prevent vascular calcification. To study this further, we wish to conduct a randomised double-blinded controlled clinical trial of increasing dialysate Ca from 1.25 mmol/L (standard dialysate concentration) to 1.50 mmol/L in patients with ESKD and secondary hyperparathyroidism on maintenance haemodialysis (HD). The overall effect of increased dialysate calcium will be gauged by its effect on serum calcification propensity (T50) and on markers of bone turnover.
This study is a rolling arm study of pembrolizumab in combination with investigational agents in pediatric participants with relapsed or refractory classical Hodgkin lymphoma (cHL), solid tumors with microsatellite instability-high (MSI-H)/mismatch repair deficient (dMMR) or tumor mutational burden-high (TMB-H), or advanced melanoma. This study will have 2 parts: a safety lead-in to demonstrate a tolerable safety profile and confirm a preliminary recommended phase 2 dose (RP2D) (Part 1) followed by an efficacy evaluation (Part 2). Participants will be assigned to a treatment arm (either Part 1 or Part 2) that is open for enrollment. There will be no hypothesis testing in this study.
This study is being done to answer the following question: Is Stereotactic Body Radiation Therapy or SBRT (a form of radiation therapy which can deliver high doses of radiation to the specific painful area of the body most affected by cancer, while keeping the radiation beams away from the healthy parts of the body that surround the cancer) better for pain relief than the standard treatment of conventional radiation therapy or CRT (a form of radiation therapy which delivers radiation to the painful area but can also negatively affect other parts of the body in the same area)
