AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults whose kidney, lung or bowel cancer came back or stopped responding to standard treatments, and who have measurable disease.
- Age
- 18 years or older
- Sex
- All sexes can join
- Disease stage
- Relapsed or refractory ccRCC, pRCC, NSCLC or CRC, with disease progression on standard-of-care therapies. Disease must be measurable by RECIST 1.1. ECOG performance status of 0 or 1.
- Earlier treatment
- Must have had standard-of-care therapies and the disease progressed. Cannot have had an investigational anti-ENPP3/CD203c therapy. Cannot have had systemic cancer therapy within 5 half-lives of the first dose.
- Biomarker or test result
- Enough tumor sample must be available (slides or archival FFPE blocks).
Main reasons for not taking part
- Known active central nervous system metastases or carcinomatous meningitis (previously treated and stable brain metastases are allowed)
- Active autoimmune disease (some mild forms are allowed)
- Serious infection needing IV anti-infective treatment within 14 days before the first dose
- Serious allergic reaction to monoclonal antibody therapy
- Another cancer that is progressing or needed treatment in the past 2 years

A Phase 1 Multiple Dose Study to Evaluate the Safety and Tolerability of XmAb819 in Subjects With Relapsed or Refractory Clear Cell Renal Cell Carcinoma
The purpose of this study is to assess the safety and tolerability of XmAb®819 administered intravenous (IV) or subcutaneous (SC) in subjects with relapsed or refractory clear cell renal cell carcinoma and to identify the minimum safe and biologically active dose and the recommended dose (RD).
Inclusion: Subjects must have measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) as assessed by the local site investigator. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions; Subjects who have relapsed and refractory ccRCC, pRCC, NSCLC, and CRC with evidence of disease progression on standard-of-care therapies; ECOG performance status of 0 or 1; All subjects must have adequate tumor sample available (slides or archival FFPE blocks).
Exclusion: Prior treatment with an investigational anti-ENPP3/CD203c therapy; Systemic antineoplastic therapy within 5 half-lives on the first dose of study treatment; Failure to recover from any clinically significant toxicity related to previous anticancer treatment; Have known active central nervous system metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are radiologically stable,; Evidence of any serious infection requiring IV anti-infective treatment within 14 days prior to the first dose of study drug; History of serious allergic or anaphylactic/hypersensitivity reaction to monoclonal antibody therapy; Active known autoimmune disease (except that subjects are permitted to enroll if they have vitiligo; type 1 diabetes mellitus; residual hypothyroidism due to an autoimmune condition that is treatable with hormone replacement therapy only; psoriasis, atopic dermatitis, or another autoimmune skin condition that is managed without systemic therapy; or arthritis that is managed without systemic therapy beyond oral acetaminophen and nonsteroidal anti-inflammatory drugs); Have a known additional malignancy that is progressing or has required active treatment within the past 2 years.
