Many people develop joint pain, stiffness and swelling due to their cancer treatment that targets the immune system. The severity of symptoms ranges from mild to debilitating and sometimes requires delaying or stopping cancer treatment.

The usual plan is to discontinue cancer treatment and give relatively high doses of a medication called prednisone (a steroid, which is an anti-inflammatory medication which may suppress the immune system) with a gradual lowering of the dose over several weeks. While this can be effective, prednisone can cause a number of side effects, and it is not known if this is the best or safest treatment.

Hydroxychloroquine is a medication that is often used to treat inflammatory joint pain, such as rheumatoid arthritis, has relatively few side effects when compared to prednisone, and may be effective at treating this condition.

The purpose of this study is to find out whether it is better to receive hydroxychloroquine and prednisone, or prednisone alone for joint pain. To do this, some participants will get hydroxychloroquine and some will receive a placebo (a substance that looks like the study drug but does not have any active or medicinal ingredients). A placebo is used to make the results of the study more reliable.

This is a double-blinded study, which means that neither participants nor the study doctor or study staff will know which group participants are allocated. After 12 weeks of study treatment, the blind will be opened and participants will be informed which treatment was given.

Inclusion Criteria

Patients must be 18 years of age, or older
Patients must be capable of providing consent to enrolment and treatment
Patients with a performance status of ECOG 0-2 will be eligible for enrolment (see appendix A)
Patients with histologically confirmed cancer receiving anti-PD1 or anti-PDL1 monoclonal antibody ICI therapy, either alone or in combination with anti-CTLA4 monoclonal antibody ICI therapy who develop CTCAEv5.0 grade 2 arthritis or arthralgia that has developed on, or after, ICI therapy and is felt to be treatment related (irAA)
Adequate hepatic and renal function defined by the following laboratory parameters
AST and ALT and alkaline phosphatase 2.5x ULN
Total bilirubin 1.5x ULN
Serum creatinine upper limit of institutional normal OR calculated creatinine clearance of 60 mL/min using the Cockcroft-Gault formula
Women of child bearing potential (WOCBP) must have a negative serum (or urine) pregnancy test at the time of screening. WOCBP is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy or bilateral salpingectomy) and is not postmenopausal. Menopause is defined as 12 months of amenorrhea in a woman over age 45 years in the absence of other biological or physiological causes. In addition, females under the age of 55 years must have a serum follicle stimulating hormone, (FSH) level > 40 mIU/mL to confirm menopause
Patients of childbearing / reproductive potential should use highly effective birth control methods, during the study treatment period and for a period of 3 months after the last dose of study drug. A highly effective method of birth control is defined as those that result in low failure rate (i.e. less than 1% per year) when used consistently and correctly. These may include: hormonal contraceptives (e.g. combined oral contraceptives, patch, vaginal ring, injectables, and implants); intrauterine device (IUD) or intrauterine system (IUS); vasectomy and tubal ligation. Double-barrier methods may be acceptable in circumstances when highly effective methods cannot be implemented (e.g. male condom with diaphragm, male condom with cervical cap). Note: Contraceptive requirements for the oncology regiments will apply, if they are more stringent than those for this trial. Abstinence is acceptable if this is established and preferred contraception for the patient and is accepted as a local standard
Female patients who are breast-feeding should discontinue nursing prior to the first dose of study treatment and until 3 months after the last dose of study drug
Male patients should agree to not donate sperm during the study and for a period of at least 3 months after last dose of study drug
Absence of any condition hampering compliance with the study protocol and follow- up schedule; those conditions should be discussed with the patient before registration in the trial

Exclusion Criteria

History of inflammatory arthritis, including, but not limited to: Rheumatoid arthritis, systemic lupus erythematosus, Sjogren's syndrome, Ankylosing spondylitis or other chronic inflammatory arthritis. Note: Patients with a known history of stable osteoarthritis will not be excluded
Patients with an indication for systemic immunosuppressive medications or corticosteroids. Patients with CTCAEv5.0 grade 2 irAE's other than irIAA (ie. colitis, pneumonitis, rash, etc) are not eligible for trial, with the exception of endocrinopathies that are being treated with hormone replacement alone and not systemic immunosuppressive medications or corticosteroids
Patients with G6PD deficiency, porphyria or psoriasis
Patients weighing < 40 kg
Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), unstable angina, congestive heart failure ( New York Heart Association Classification Class II), or serious cardiac arrhythmia requiring medication
Diagnosis of immunodeficiency
Current use of immunosuppressive medication, EXCEPT for the following: a. intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection); b. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)
Prolonged corrected QT interval or concurrent medications that prolong QT interval
Known prior severe hypersensitivity to investigational product or any component in its formulations, including known severe hypersensitivity reactions to monoclonal antibodies (CTCAEv5.0 Grade 3)
Other severe acute or chronic medical conditions including inflammatory bowel disease, immune pneumonitis, pulmonary fibrosis or psychiatric conditions including recent (within the past year) or active suicidal ideation or behavior; or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study
