Primary Outcome Measures

Outcome Measure Measure Description Time Frame

Frequency of dose interruptions/reductions Up to 12 treatment cycles or through treatment discontinuation, whichever occurs first
Duration of dose interruptions/reductions Up to 12 treatment cycles or through treatment discontinuation, whichever occurs first

Inclusion Criteria

  • Patients with histologically confirmed, advanced-stage protocol-specified solid tumors.
  • Confirmed ROR1 tumor expression.
  • Patients who have undergone at least one prior systemic therapy and have radiologically or clinically determined progressive disease during or after most recent line of therapy, and for whom no further standard therapy is available, or who are intolerable or have medical contraindications to standard therapy.

Exclusion Criteria

  • Prior treatment with any agent targeting ROR1 or prior treatment with a CD3 T-cell engaging therapy.
  • Prior treatment with chimeric antigen receptor (CAR) cell therapy within 90 days prior to first dose of NM32-2668.
