- Platelet count >= 100 x 10^9/L

- Prothrombin time (PT) or partial thromboplastin time (PTT) < 1.5 x upper limit of normal (ULN), except subjects on anticoagulation for venous thromboembolism
- Calculated creatinine clearance or radioisotope glomerular filtration rate (GFR) > 60 mL/min
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 2.5 x ULN for age
- Total bilirubin < 1.5 x ULN for age
- Serum albumin >= 2
- Any disorder that compromises the ability of the patient or patient’s legally acceptable representative to give written informed consent and/or to comply with the study procedures
- Patients who will not be available for protocol required study visits, to the best of the subject and investigator’s knowledge
- History of hypersensitivity to any of the study agents (gemcitabine, docetaxel, or hydroxychloroquine) or to any component of the formulation
- Patients who have previously received gemcitabine or docetaxel
- Men and woman of reproductive potential, unwilling to practice a highly effective method of birth control for the duration of the study and continuing for 2 weeks (for women) and 12 weeks (for men) after receiving the last dose of study drug. Highly effective methods of birth control include sexual abstinence (men, women); vasectomy or a condom used with spermicide (men) in combination with barrier methods, hormonal birth control or intrauterine device (IUD) (women)
- Women who are lactating/breastfeeding or planning to become pregnant during the duration of the study
- History or current diagnosis of a second neoplasm. Exception: adequately treated non-melanoma skin cancer, curatively treated in-situ disease, or other solid tumors curatively treated with no evidence of disease for >= 2 years
- Myocardial infarction within 6 months of study day 1, symptomatic congestive heart failure (New York Heart Association > class II), unstable angina, or unstable cardiac arrhythmia requiring medication, or uncontrolled hypertension (systolic > 160 mmHg or diastolic > 100 mmHg)
- Active infection requiring intravenous (IV) antibiotics within 2 weeks of study enrollment
- Significant gastrointestinal disorder(s) that in the opinion of the investigator (e.g., Crohn’s disease, ulcerative colitis, extensive gastrointestinal resection) may influence drug absorption
- Known positive test for human immunodeficiency virus (HIV)
- Subjects with acute hepatitis B and C are not eligible. Subjects with chronic hepatitis B or C are eligible if their condition is stable and, in the opinion of the investigator and Amgen physician, if consulted, would not pose a risk to subject safety
- Toxicities from prior anti-tumor therapy not resolved to Common Terminology Criteria for Adverse Events (CTCAE) grade 0 or 1, or to levels dictated in the eligibility criteria. Grade 2 toxicities from prior anti-tumor therapy that are considered irreversible (defined as having been present and stable for > 4 weeks), such as stable grade 2 peripheral neuropathy or ifosfamide-related proteinuria, may be allowed if they are not otherwise described in the exclusion criteria AND there is agreement to allow by the principal investigator
- Prior participation in an investigational study and/or procedure within 21 days of study day 1
- Anti-tumor therapy within 21 days of study day 1 including chemotherapy, antibody therapy, or other investigational agent. Enrollment of subjects that have received molecularly targeted agents less than 28 days prior to study day 1 will be permitted if more than 14 days and at least 5 drug half-lives have passed prior to receiving the first dose of HCQ
- Major surgery within 28 days of study day 1
- Any co-morbid medical disorder that may increase the risk of toxicity, in the opinion of the investigator
- All herbal supplements, vitamins, and nutritional supplements taken within the last 30 days prior to dosing on day 1 (and continued use, if appropriate), must be reviewed and approved by the principal investigator (PI)
- Patients with pre-existing maculopathy or retinopathy of the eye
I. To determine the maximum tolerated dose (MTD) and preliminary safety of hydroxychloroquine (HCQ) when administered with gemcitabine and docetaxel (G+D) in patients with recurrent/metastatic osteosarcoma. (Phase I)
II. To determine whether gemcitabine and docetaxel (G+D) in combination with hydroxychloroquine (HCQ) increases the disease control rate in patients with recurrent/metastatic osteosarcoma at 4 months as compared to historic controls. (Phase II)
I. To determine the objective response rate by Response Evaluation Criteria in Solid Tumors (RECIST) of the combination of G + D + HCQ in patients with recurrent/metastatic osteosarcoma.
II. To estimate the event-free survival (EFS), progression-free survival (PFS), and overall survival (OS) for patients with recurrent/metastatic osteosarcoma treated with G+D+HCQ.
III. To estimate the toxicity rates of oral HCQ when administered in conjunction with G+D.
IV. To investigate the pharmacokinetics (PK) of the combination in patients with recurrent/metastatic osteosarcoma.
I. To describe the metabolic response rates of G + D + HCQ in patients recurrent/metastatic measurable osteosarcoma by positron emission tomography (PET)/computed tomography (CT) at 6 weeks.
II. To assess pre-/post-treatment changes in autophagy biomarkers (autophagic vesicles, LC3B puncta, p62, and HMGB1), HSP27, and pHSP27 expression in tumor samples at baseline and during cycle #2 of treatment with G + D + HCQ.
III. To assess the relationship between probability of response and/or disease control and tumor HSP27, pHSP27, ALDH1A1, and HLTF expression.
IV. To complete functional proteomic profiling of autophagic and apoptotic pathways on tumor samples by RPPA and correlate findings with the probability response and disease control.
OUTLINE: This is a phase I, dose-escalation study of hydroxychloroquine followed by a phase II study.
Participants receive hydroxychloroquine orally (PO) once daily (QD) or twice daily (BID) on days 1-21, gemcitabine intravenously (IV) over 90 minutes on days 1 and 8, and docetaxel IV over 1 hours on day 8. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, participants are followed up at 1 year.
