Brief summary
Background and purposes:Chloroquine (CLQ), an antimalarial drug, has a lysosomatrophic effect associate with increase the sensibility of Radiation through leakage of hidroliticenzimes, increase of apoptosis, autophagy mediated by lysosomalhidrolases and increase of oxidative stress in vitro. In this phase II study we evaluated the efficacy and safety as radiosensitizing of the Chloroquine plus concomitant 30 Gray (Gy) of Whole-brain irradiation (WBI)in patients with brain metastases (BM) from solid tumors.
Detailed description
Seventy-three eligible patients were randomized. Thirty-nine patients received WBI (30 Gy in 10 fractions over 2 weeks) concomitant with 150 mg of CLQ for 4 weeks (the CLQ group). Thirty-four patients received the same schedule of WBI concomitant with a placebo for 4 weeks (the control arm). All the patients were evaluated for quality of life (QoL) using the EORTC QLQ-C30 questionnaire (Mexican version) before beginning radiotherapy and one month later.
Interventions
The patients in the Chloroquine group received 30 Gy of total brain radiotherapy in 10 daily fractions from Monday to Friday. Furthermore, the Chloroquine plus WBI arm received a daily single dose of 150 mg CLQ po 1 hour prior to the radiation treatment, beginning during the first radiotherapy fraction and continuing for 28 days
30 Gy in 10 daily fractions from Monday to Friday

| Overall Response Rate | Every third month after randomization until 24 months follow-up. Measured by brain MRI | Corresponding Complete plus Partial Response according with RECIST 1.1 Criteria |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Central Nervous System Progression Free Survival | From time to progression to 24 months follow up | Clinical o radiological brain progression or death. Radiological Progression is measured by RECIST 1.1 Criteria |
Other
| Measure | Time frame | Description |
|---|---|---|
| Quality of life in brain metastases | The quality of life questionnaires were completed 1 day before radiotherapy began and 1 month later. | The 30-item EORTC Quality of Life (QoL) Questionnaire (EORTC QLQ-C30) version 3.0 (Mexican version) was used in this trial. The EORTC QLQ-C30 v3 consisted of five multi-item functional scales, three symptom scales, a global health status/QoL scale, and six single items |
