Erlotinib with or without hydroxychloroquine in chemo-naive advanced NSCLC and (EGFR) mutations. Boston, MA: National Library of Medicine (US): 2009-2015. Chloroquine malarone How to wean from plaquenil Oct 01, 2018 Mechanism of Action Chloroquine, a 4-aminoquinoline, is an anti-protozoal agent. The precise mechanism by which Chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. Jan 18, 2017 "Chloroquine was administered at 150 mg/d, starting on day 5 after surgery, and was continued for 12 months" As chloroquine phosphate comes in doses of 250, this was likely given on a once daily schedule 250 mg chloroquine phosphate once daily = 150 chloroquine once daily. The autophagy inhibitor chloroquine overcomes the innate resistance of wild-type EGFR non-small-cell lung cancer cells to erlotinib. Journal of Thoracic Oncology 86 693-702. Link here 2. The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Since the pivotal trial evaluating the effect of temozolomide (TMZ), overall survival has not increased. National Insitute of Health; Massachusetts General Hospital.

Suppression 400 mg 310 mg base orally on the same day every week Comments-Suppressive therapy should begin 2 weeks prior to exposure; however, failing this, an initial dose of 800 mg 620 mg base may be taken in 2 divided doses 6 hours apart. Hydroxychloroquine Dosage Guide with Precautions -. Repurposing Drugs 101 - Chloroquine & Lung Cancer. Chloroquine - FDA prescribing information, side effects.. Epidermal growth factor receptor tyrosine kinase inhibitors EGFR-TKIs, including gefitinib, are effective for non-small cell lung cancer NSCLC patients with EGFR mutations. However, these patients eventually develop resistance to EGFR-TKI. The goal of the present study was to investigate the involvement of autophagy in gefitinib resistance. Consequently, inhibiting autophagy with chloroquine significantly enhanced tumor cell death induced by gefitinib and AKT inhibitors in EGFR M+ cells in vitro, and produced greater tumor shrinkage in EGFR M+ xenografts in vivo. Oct 01, 2014 Chloroquine is an established antimalarial agent that has been recently tested in clinical trials for its anticancer activity. The favorable effect of chloroquine appears to be due to its ability to sensitize cancerous cells to chemotherapy, radiation therapy, and induce apoptosis.
