Interventions

  • Durvalumab — BIOLOGICAL
    Durvalumab is a human immunoglobulin G (IgG)1 kappa monoclonal antibody directed against human PD-L1. Durvalumab selectively binds human PD-L1 with high affinity and blocks its ability to bind to PD-1 and cluster of differentiation (CD)80. The fragment crystallizable (Fc) domain of durvalumab contains a triple mutation in the constant domain of the IgG1 heavy chain that reduces binding to the complement component C1q and the Fc gamma receptors responsible for mediating antibody dependent cell mediated cytotoxicity.
  • Oleclumab — BIOLOGICAL
    Oleclumab is a human immunoglobulin G1 lambda monoclonal antibody (mAb) with a triple mutation in the heavy chain constant region for reduced effector function. Oleclumab selectively binds to cluster of differentiation 73 (ecto-5'-nucleotidase) (CD73) and inhibits CD73-associated ectonucleotidase activity, thereby inhibiting the CD73-mediated production of immunosuppressive adenosine. Extracellular adenosine contributes to the immunosuppressive effects of both regulatory T cells and myeloid derived suppressor cells, among others. This, in turn, leads to increased antitumor immunity.

Study Details

This is a Phase II, prospective, non-randomized, open-label trial involving cancer patients with known inflamed tumor types. Patients with previously treated advanced/metastatic non-small cell lung cancer or renal cell cancer will be recruited in near equal distribution. All patients must have documented response or prolonged stable disease to previous immunotherapy. At present, we plan to enrol 55 patients, to be treated with durvalumab and oleclumab. The regimen will consist of durvalumab 1500 mg given by vein every 4 weeks and oleclumab 3000 mg given by vein every 2 weeks x 4 doses then IV every 4 weeks till disease progression, withdrawal of subject consent, or another reason for discontinuation. Estimated total duration from time to first subjects consent to last subject's last visit is approximately 36 months.

Arms

  • Experimental: Durvalumab and Oleclumab
    A single dose level for oleclumab and durvalumab will be used, comprising of Oleclumab 3000 mg IV Q2W for 4 doses, then Q4W AND Durvalumab 1500 mg IV Q4W

Primary Outcome Measure

Association between cfMeDIP and Response (defined as either complete response, partial response, or stable disease ≥ 4 cycles, as per RECIST 1.1. Association between cfMeDIP and Toxicity (defined as ≥ Grade 2 immune- adverse event (AE) as per CTCAE 5.0). [ Time Frame: 3 years ]
