Study type
Description of intervention(s) / exposure
Each participant will receive a weight-based single dose ALMB-0168 as IV injection at one of the 7 dose levels (1mg/kg to 3mg/kg, 6mg/kg, 12mg/kg, 20mg/kg, 25mg/kg and 30mg/kg) on Day 1 of every 21-day cycle for up to 6 months or maximally 8 cycles. As this is an open-label study, no randomisation will be performed. Assignment of a patient to a particular dose level will be coordinated by the sponsor upon patient registration.
Treatment will be discontinued when disease progression or a change of therapy is necessary. Per Investigator's discretion, ALMB-0168 treatment may be given for longer term to subjects who can continue benefit from it.

Primary outcome [1] 323144 0
The primary outcome is dose-limiting toxicity (DLT), from day 1 to day 21 during the first cycle of the treatment (21 days) after study drug administration. Toxicities will be assessed by performing physical examination, vital signs, ECG, laboratory testing and graded according to NCI-CTCAE version 5.0.
Timepoint [1] 323144 0
Timepoint: The first 3 weeks of first dosing will be defined as DLT evaluation period i.e. Day 1 to Day 21.

Secondary outcome [1] 380952 0
Other safety variables including adverse events (AEs), vital signs measurements, lab values, ECGs etc. Those safety parameters will be collected from the start of study drug administration to the end of study (28 days after the last dose) by weekly visit to the clinic (cycles1&2) and once every 3 weeks (cycle3 and after), and performing physical examinations, obtaining vital signs and ECG readings. Incidence of treatment-emergent AEs (TEAEs) will be graded according to NCI CTCAE v5.0.
Timepoint [1] 380952 0
Timepoint: All patients will be closely monitored and will be seen at the clinic on a weekly basis then approximately 28 days after the last treatment and will be followed up for up to one years to evaluate longer term outcomes.
Secondary outcome [2] 381470 0
Pharmacokinetic (PK) parameters such as Cmax, tmax,AUC0-t, AUC0-8 (first dose only), t1/2, CL, and Vz. These parameters will be calculated from serum concentration of ALMB-0168 measured by ELISA using blood samples collected at the following time points:
Cycle 1, Day 1 - Predose, postdose time after end of infusion (immediately, 1 hour, 2 hours, 4 hours, 8 hours);
Cycle 1 Day 2 - Approx. 24 hours following dosing on Day 1

Cycle 2 and every subsequent cycle - Day 1 - pre-dose only
End of Study Visit - 28 days after last dose
Timepoint [2] 381470 0
All patients will be closely monitored and will be seen at the clinic on a weekly basis then approximately 28 days after the last treatment and will be followed up for up to one years to evaluate longer term outcomes.
Secondary outcome [3] 381712 0
The emergence of antibodies to ALMB-0168 to assess immunogenicity of ALMB-0168
Timepoint [3] 381712 0
Blood samples for the determination of antibodies to ALMB-0168 will be obtained at the following timepoints: Cycles 1 & 2 - Day 1 (pre-dose) and Day 15, Cycle 3 and all subsequent cycles - Day 1 (pre-dose).

Statistical methods / analysis
The total number of patients to be enrolled in the dose escalation portion of the study is dependent upon the observed safety profile, which will determine the number of patients per dose cohort, as well as the number of dose escalations required to achieve the MTD and subsequent RP2D. Based on the standard "3+3"design, the number of patients enrolled for the entire study will not be less than 2 and not more than 46, including up to 10 patients with osteosarcoma or other bone metastatic disease who will be treated in the final RP2D dose expansion group. The actual number depends on the number of dose levels evaluated and the toxicity documented.

Brief summary
The purpose of this study is to test the safety of a new medication (called ALMB-0168) in people with malignant bone cancer lesions either from bone cancer or from migration of other cancers.

Who is it for?

You may be eligible for this study if you are aged 16 or older, and have confirmed bone cancer (osteosarcoma) or cancer cells in the bone originated from other cancers which has been deemed untreatable.

Study details

All participants in this study will receive the active medication ALMB-0168. The dose will depend on when the participant enrolls in the study. The medication is administered through a needle in the arm, and will continue for up to 6 months. As part of this study, all participants will have additional blood tests, imaging scans and answer questions regarding to your health.

It is hoped this research will demonstrate the safety of ALMB-0168 and find the ideal dose for larger-scale studies.
