Criteria

Inclusion Criteria:

1. Fully informed and signed informed consent.

2. Male or female, 18 years and older.

3. Histologically/cytologically confirmed malignant solid tumors.

4. Radiographic evidence of at least one bone metastasis.

5. Eligible fertile patients (male and female) must agree to use an effective method of contraception with their partners from the signing of informed consent until at least 6 months after the last treatment.

6. Adequate organ functions.

7. Albumin-corrected serum calcium ≥ 1 x lower limit of normal (LLN) at screening (calcium supplement is not allowed within 8 hours prior to screening).

8. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2.

9. Life expectancy ≥ 6 months

Exclusion Criteria:

1. Previous or present osteomyelitis or osteonecrosis of the jaw; unhealed dental or oral surgery wounds; acute disease of the tooth or jaw requiring oral surgery; and invasive dental surgery planned to be received during the study;

2. Radiotherapy or orthopaedic surgery is planned for patients during the study;

3. Known symptomatic brain metastases.

4. Abnormal bone metabolism (such as Paget's disease, Cushing's syndrome, hyperprolactinemia), rheumatoid arthritis, parathyroid disease

5. Clinically significant disease (such as uncontrolled diabetes, congestive heart failure, hypertension>150/90 mmHg).

6. Known hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV) or other active viral infection.

7. Systemic therapy of active bacterial infection or fungal infection within 7 days prior to randomization.

8. Pregnant or lactating women.

9. Prior use of antibody against nuclear factor kappa-B (NFκB) ligand (RANKL).

10. Participated in other clinical studies and received other experimental drugs within 4 weeks prior to randomization.

11. Prior use of bisphosphonate within 4 weeks prior to randomization.

12. Prior use of one of following osteoporosis medications within 6 months prior to randomization (Parathyroid hormone (PTH) analogue, calcitonin, osteoprotegerin, mithramycin, and strontium).

13. Adverse reactions from the previous anti-tumor treatment have not yet recovered to ≤ level 1 based on CTCAE 5.0 (except for the toxicity without safety risk judged by the investigator, such as hair loss)

14. Known hypersensitivity to any of the products to be administered during the study (such as JMT103)

15. Not suitable for this study as determined by the investigator due to other reasons.
