  • serous, endometroid or clear-cell endometrial cancer, or

  • adenocarcinoma of the lung, or

  • triple-negative breast cancer, defined as negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2), according to American Society of Clinical Oncology/College of American Pathologists recommendations (Hammond et al. 2010; Wolff et al. 2018), or

  • liposarcoma or leiomyosarcoma, or

  1. Confirmed ROR1 tumor expression (≥ 25% of tumor cells staining with ≥ 1+ intensity in Part I and ≥ 1% of tumor cells staining with ≥ 1+ staining intensity in Parts II and III), as assessed by a central laboratory using an investigational, analytically validated ROR1 assay. Participants without archival tumor tissue (less than 24 months old) available for testing must have a lesion amenable to biopsy. The requirement for ROR1 expression may be modified to include patients with higher ROR1 expression based on emerging data from the study. Patients with leiomyosarcoma or liposarcoma may be enrolled without prospective testing except in part I of the trial. 5. 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.

  2. Patients must have at least one measurable or non-measurable lesion as per RECIST version 1.1. Note: the measurable lesion(s) can be inside the field of prior radiotherapy provided that the lesion has documented progression post radiotherapy as per RECIST version 1.1.
