NCT03517488

Brief Summary

This is a Phase 1, multiple dose, ascending dose escalation study to define a MTD/RD and regimen of XmAb20717, to describe safety and tolerability, to assess PK and immunogenicity, and to preliminarily assess anti-tumor activity of XmAb20717 in subjects with selected advanced solid tumors.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically or cytologically confirmed diagnosis of one of the following advanced solid tumors:
  • PART A (Dose Escalation Cohorts)
  • Melanoma;
  • Breast carcinoma that is estrogen receptor, progesterone receptor, and Her2 negative (triple-negative breast cancer; TNBC);
  • Hepatocellular carcinoma;
  • Urothelial carcinoma;
  • Squamous cell carcinoma of the head and neck;
  • Renal cell carcinoma (clear cell predominant type);
  • Microsatellite instability-high or mismatch repair deficient colorectal carcinoma or endometrial carcinoma;
  • Non-small cell lung carcinoma;
  • Gastric or gastroesophageal junction adenocarcinoma
  • Mesothelioma;
  • High-grade neuroendocrine carcinoma, including small cell carcinoma of the lung
  • Cervical cancer;
  • Squamous cell carcinoma of the anus
  • +24 more criteria

You may not qualify if:

  • Subjects currently receiving other anticancer therapies, with the exception of subjects with adenocarcinoma of the prostate, who may continue luteinizing hormone-releasing hormone (LHRH) analogue therapy.
  • Treatment with any CTLA4 antibody within 6 weeks of the start of study drug.
  • Treatment with nivolumab or any PDL1 or PDL2-directed antibody within 4 weeks of the start of study drug.
  • Treatment with pembrolizumab within 4 - 12 weeks of the start of study drug (cohort dependent).
  • Treatment with any other anticancer therapy within 2 weeks of the start of study drug (i.e., other immunotherapy, chemotherapy, radiation therapy, etc.). Subjects with prostate cancer may continue LHRH analogue therapy.
  • A life-threatening (Grade 4) immune-mediated AE related to prior immunotherapy.
  • Failure to recover from any immune-related toxicity from prior cancer therapy to ≤ Grade 1, except if previous immune-related endocrinopathy is medically managed with hormone replacement therapy only.
  • Failure to recover from any other toxicity (other than immune-related toxicity) related to previous anticancer treatment to ≤ Grade 2.
  • Have known active CNS metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, ie, are without evidence of progression for at least 4 weeks by repeat imaging, are clinically stable, and without requirement of steroid treatment for at least 14 days prior to first dose of study treatment.
  • Active known or suspected autoimmune disease (except that subjects are permitted to enroll if they have vitiligo; type 1 diabetes mellitus or 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 non-steroidal anti-inflammatory drugs).
  • Has any condition requiring systemic treatment with corticosteroids, prednisone equivalents, or other immunosuppressive medications within 14 days prior to first dose of study drug (except that inhaled or topical corticosteroids or brief courses of corticosteroids given for prophylaxis of contrast dye allergic response are permitted).
  • Receipt of an organ allograft.
  • Prior treatment with any checkpoint inhibitor therapy regimen that targets both PD1/L1 and CTLA-4.
