Clinical Trial Summary

The purpose of this project is to test the addition of a new treatment called denosumab to standard immunotherapies for patients with metastatic melanoma. Denosumab has been used for many years to help treat cancers such as prostate cancer and breast cancer, but it is not currently used in melanoma. We hope the addition of denosumab to current melanoma therapies will make these treatments work better without adding to the side effects.

Who is it for? You may be eligible to join this study if you are aged 18 years or over and have been diagnosed with metastatic melanoma (melanoma that has spread).

Study details: Nivolumab and ipilimumab are approved treatments for advanced melanoma in Australia and overseas. Patients with metastatic melanoma, who are not enrolled in a study, are commonly prescribed nivolumab alone or the combination of nivolumab and ipilimumab as standard care. However, there is limited information on the effectiveness and safety of these treatments in combination with denosumab. Recent melanoma research in animal models has shown that denosumab can make immunotherapies such as ipilimumab and nivolumab work better. Because denosumab has been used in patients with breast and prostate cancer for a long time and is safe, we now want to test the benefits and safety of adding denosumab to immunotherapies in this study.

3. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

4. Patient willing and able to provide written informed consent.

5. Treatment naïve (no prior systemic therapy for unresectable or metastatic melanoma). Note that prior adjuvant or neoadjuvant melanoma therapy (except anti-PD1 and/or anti-CTLA-4 therapy) is permitted if it was completed at least 6 weeks prior to allocation, and all related adverse events have either returned to baseline or resolved.

6. Willing and able to comply with scheduled visits, treatment schedule, laboratory testing, and other requirements of the study.

7. Measurable disease by CT or MRI per RECIST 1.1 criteria.

8. Patients with asymptomatic brain metastasis may be considered for enrollment. These patients can have up to 3 lesions that are = 1.5 cm in diameter. The brain metastasis may be naïve to local therapy or have previously received local therapy (surgery, stereotactic radiotherapy/radiosurgery but not whole brain radiotherapy) and are stable. Asymptomatic from brain metastases at study entry implies that these patients are without corticosteroid, antiepileptics, analgesia or any other treatment for the management of neurological symptoms. Patients with completely resolved neurological symptoms are permitted.

9. At least 2 weeks since the completion of prior therapy, including surgery or radiotherapy.

10. Screening laboratory values must meet the following criteria and should be obtained within 14 days prior to registration

• WBC = 2000/µL

• Neutrophils = 1500/µL

• Platelets = 100 x103/µL

• Haemoglobin > 9.0 g/dL

• Serum creatinine = 1.5 x ULN or creatinine clearance (CrCl) = 40 mL/min (if using the Cockcroft-Gault formula below):

Female CrCl = (140 - age in years) x weight in kg x 0.85 72 x serum creatinine in mg/dL

Male CrCl = (140 - age in years) x weight in kg x 1.00 72 x serum creatinine in mg/dL

• AST/ALT = 3 x ULN

11. Women of childbearing potential (WOCBP) must use appropriate method(s) of contraception. WOCBP should use an adequate method to avoid pregnancy for 23 weeks (30 days plus the time required for nivolumab to undergo five half-lives) after the last dose of investigational drug. Appropriate methods of contraception includes:

• Intrauterine device with a documented failure rate of less than 1% per year.

• Vasectomised partner who is sterile prior to the female partner patient's commencement of study treatment and is the sole sexual partner for that female.

• Double barrier contraception: male condom and occlusive cap (diaphragm or cervical /vault caps).

12. Women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours prior to the start of treatment.

13. Men who are sexually active with a WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men receiving nivolumab and who are sexually active with a WOCBP will be instructed to adhere to contraception for a period of 31 weeks after the last dose of investigational product. Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men, do not require contraception. Effective contraception includes:

• Documented vasectomy and sterility

• In the partner - intrauterine device with a documented failure rate of less than 1% per year

• Double barrier contraception: male condom and occlusive cap (diaphragm or cervical/vault caps).

14. Patients must agree to have archival tumour material collected. This can either be from a resected lymph node, primary melanoma, or metastatic site. Where possible, the most recently acquired tumour specimen should be provided. If archival tumour tissue is not available, subjects must consent to allow the acquisition of additional tumour tissue prior to trial entry.

15. Patients enrolled on the biopsy cohort must be agreeable to have serial tumour biopsies during the study.

Exclusion Criteria:

1. Patients are excluded if they have symptomatic, large volume brain metastases and/or any evidence of leptomeningeal disease. Large volume brain metastasis for this study is defined as more than 3 brain metastasis and/or any of the brain metastasis being greater than 1.5 cm in dimension. Note: patients with larger brain metastasis (up to 3 cm) that has been adequately treated with prior surgery or stereotactic radiation are permitted to be enrolled as long as they have adequately recovered from the local therapy.

2. Neurological symptoms from brain metastases present at baseline (resolved neurological symptoms, prior to enrolment, are permitted).

3. Patients with uveal melanoma are excluded.

4. Prior exposure to a CTLA-4 inhibitor (e.g. ipilimumab, tremelimumab), PD-1 inhibitor (e.g. nivolumab, pembrolizumab), PD-L1 inhibitor (e.g. MEDI-4736), PD-L2 inhibitor, or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways.

5. Prior systemic treatment with a BRAF and/or MEK inhibitor

6. Prior treatment with denosumab.

7. Prior malignancy active within the previous 2 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer or carcinoma in situ of the cervix or breast.

8. Life expectancy of = 6 months.

9. Prior history or current evidence of osteonecrosis/osteomyelitis of the jaw.

• Melanoma Stage Iii
• Melanoma Stage Iv

Intervention

Drug:
• Denosumab
Denosumab is a fully human monoclonal immunoglobulin type 2 (IgG2) antibody that binds with high affinity and specificity to RANK ligand (RANKL) and neutralises the activity of human RANKL, similar to the action of endogenous osteoprotegerin (OPG). Denosumab binding prevents the activation of RANK and inhibits the formation, activation, and survival of osteoclasts. As a consequence, bone resorption and cancer-induced bone destruction are reduced.
• Nivolumab
Nivolumab is a human monoclonal antibody that targets the programmed death-1 (PD-1) cluster of differentiation 279 (CD279) cell surface membrane receptor. Nivolumab inhibits the interaction of PD-1 with its ligands, PD-L1 and PD-L2, resulting in enhanced T-cell proliferation and interferon-gamma (IFN-?) release in vitro.
• Ipilimumab
Ipilimumab is a fully human monoclonal immunoglobulin specific for human cytotoxic T-lymphocyte antigen 4 (CTLA-4), which is expressed on a subset of activated T cells. Ipilimumab is a monoclonal antibody(mAb) that binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, cluster of differentiation antigen 80 / cluster of differentiation antigen 86 (CD80 / CD86). Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation, including the activation and proliferation of tumor-infiltrating T-effector cells.
