This is a first-in-human, open-label, multi-center, Phase 1/2, dose-escalation study with expansion cohorts to evaluate NM21-1480 for safety and immunogenicity, to determine the maximal tolerated dose and recommended Phase 2 dose, define the pharmacokinetics, to explore the pharmacodynamics, and to obtain preliminary evidence of the clinical activity in adult patients with selected advanced solid tumors.

Number of Participants With Treatment-related Adverse Events as Assessed by CTCAE v5.0
Frequency and severity of adverse events
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Maximum Tolerated Dose (MTD) of NM21-1480
To determine the MTD of NM21-1480 based on Part A. Note, No MTD was identified across all dose levels tested and a technical MTD was defined by the SMC as 800 mg following Part A, which was updated to 1400 mg by the SMC after completion of Part A-2.
Time frame: Cycle 1 (28 days).
Determination of Phase 2 Dose of NM21-1480
To determine the recommended Phase 2 dose of NM21-1480 for Part B of the study
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
To Determine the Anti-tumor Activity (Best Overall Response) of NM21-1480 According to RECIST 1.1
For best overall response (BOR) and objective response rate (ORR), patients in the Efficacy Analysis Set (EAS) who did not have sufficient on-study tumor assessments to characterize response were included in the denominator when calculating BOR percent and ORR and were thus treated as non-responders.
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the Maximum Observed Serum Concentration Determined by Direct Inspection of the Concentration Versus Time Data (Cmax)
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the the Minimum Observed Serum Concentration Determined by Direct Inspection of the Concentration Versus Time Data (Cmin)
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the Time From Dosing at Which Cmax is Apparent Determined by Direct Inspection of the Concentration Versus Time Data (Tmax)
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the Terminal Phase (Apparent Elimination) Rate Constant (λz)
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the Elimination Half-life (t½)
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the Area Under the Serum Concentration-time Curve Extrapolated From the Last Quantifiable Concentration to Infinity Quantifiable Concentration to Infinity (AUC[0-infinity])
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the Area Under Serum Concentration-time Curve Over Dosing Interval (AUCtau)
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the Clearance (CL)
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the Volume of Distribution (Vd)
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
Assessment of the Frequency of Specific Anti-drug Antibodies to NM21-1480
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
To Determine the Anti-tumor Activity (Duration of Response) of NM21-1480 According to RECIST 1.1
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
To Determine the Anti-tumor Activity (Time-to-response) of NM21-1480 According to RECIST 1.1
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
To Determine the Anti-tumor Activity (Progression-free Survival) of NM21-1480 According to RECIST 1.1
Time frame: From baseline to up to 12 weeks post last dose, up to 48 weeks.
