Listing a study does not mean it has been evaluated by the U. Hydroxychloroquine may inactivate these pathways and results in the death of pancreatic cancer cells. Hydroxychloroquine is approved for the treatment of non-cancerous illnesses such as rheumatoid arthritis and systemic lupus erythematous. Plaquenil precio mexico Plaquenil and eye floaters Autophagy, a cancer cell survival mechanism whereby damaged organelles, proteins and other intracellular components are recycled, appears to be critical for NET formation in pancreatic cancer. Furthermore, the autophagy inhibitor chloroquine inhibits NET formation 13, 14. We evaluated hydoxychloroquine HCQ, an inhibitor of autophagy, in patients with pancreatic cancer and analyzed pharmacodynamic markers in treated patients and mice. METHODS Patients with previously treated metastatic pancreatic cancer were administered HCQ at 400 mg n = 10 or 600 mg n = 10 twice daily. They turned to an autophagy inhibitor called hydroxychloroquine and a drug that blocks a protein in the MAPK pathway. In mice transplanted with KRAS -mutant human pancreatic tumors, treatment with both drugs together slowed tumor growth and extended survival more than either drug alone. Patients received 600 mg hydroxychloroquine orally twice per day. Patients remained on treatment indefinitely without the occurrence of disease progression, unacceptable adverse events, patient withdrawal, or discontinuation per MD decision.

Preclinical trials have shown that HCQ alone and in combination therapy leads to enhancement of tumor shrinkage. Targeting Autophagy in Cancer Update on Clinical Trials.. Hitting an Elusive Target in Pancreatic Cancer - National.. Targeting autophagy in cancer Nature Reviews Cancer. Inhibition of autophagy with hydroxychloroquine is considered a therapeutic option for cancer, and its use against mouse PDACs that developed with wild-type p53 and pancreatic tumour xenografts. Autophagy is a catabolic pathway that permits cells to recycle intracellular macromolecules, and its inhibition reduces pancreatic cancer growth in model systems. We evaluated hydoxychloroquine HCQ, an inhibitor of autophagy, in patients with pancreatic cancer and analyzed pharmacodynamic markers in treated patients and mice. Hydroxychloroquine HCQ, the analog of chloroquine, augments the effect of chemotherapies and radiotherapy on various tumors identified in the current clinical trials. Meanwhile, the toxicity of HCQ retinopathy raises concern worldwide. Thus, the potent autophagy inhibitors are urgently needed.
