Erlotinib with or without hydroxychloroquine in chemo-naive advanced NSCLC and (EGFR) mutations. Boston, MA: National Library of Medicine (US): 2009-2015. When is plaquenil used Plaquenil affect immune system Chloroquine diphosphate storage Life extension chloroquine 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. Introduction The epidermal growth factor receptor EGFR inhibitor erlotinib is much less effective in non-small-cell lung cancer NSCLC tumors with wild-type EGFR, than in tumors with activating EGFR mutations. Autophagy is a tightly regulated lysosomal self-digestion process, which may alternatively promote cell survival or type II cell death. Chloroquine has been shown to sensitise prostate cancer cells with a PTEN deletion to AKT inhibition by AZD5363 17, 48. In contrast, when we combined MK2206 and chloroquine in EGFR M+ NSCLC cells, this did not have any added benefit, but these cells are highly dependent on EGFR rather than AKT signaling for survival. 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.

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. Methods To parse the autophagy–apoptosis crosstalk pathway as a potential targeted therapy in TNBC, the activity of an EGFR inhibitor, osimertinib, alone and in combination with an autophagy inhibitor, chloroquine, was examined in EGFR-overexpressing TNBC cell line, MDA-MB-231. The nature of interaction between both drugs at various. Chloroquine Nivaquine was the first drug used for the treatment of malaria. It is effective against the blood stages of the malaria parasite and penetrates into most tissues. It is effective against Plasmodium ovale and malaria and susceptible strains of vivax and falciparum.
