Hydroxycloroquine had promising early results. However HCQ pharmacodynamic responses are difficult to assess in patients and preclinical studies in mouse models are equivocal with regard to HCQ exposure and inhibition of autophagy. 20032020 Hydroxychloroquine HCQ in Combination With Abemaciclib and Endocrine Therapy in HRHer 2- Advanced Breast Cancer After a Lead in Dose Escalation Cohort of HCQ and Abemaciclib in Advanced Solid Tumors.

These studies are designed to fail. Many trials are still underway which may show it to be effective at earlier stages or in different doses. 01082020 Hydroxychloroquine Cures Cancer.

HCQ restores antiestrogen sensitivity to resistant tumors. Estimated Study Completion Date. Hydroxychloroquine HCQ one of the disease-modifying antirheumatic drugs may lead to an inhibition of autophagy.
