Study of Durvalumab and Guadecitabine in Advanced Kidney Cancer

Prior treatment

• Brain metastases or spinal cord compression. Patients with suspected brain metastases at screening should have an MRI (preferred) or CT each preferably with IV contrast of the brain prior to study entry. Patients whose brain metastases have been treated may be considered if they have completed their treatment for brain metastasis at least 4 weeks prior to study registration provided they show radiographic stability (defined as 1 brain image, obtained after treatment to the brain metastases). In addition, any neurologic symptoms that developed either as a result of the brain metastases or their treatment must have resolved or be stable without the use of steroids for at least 14 days prior to the start of treatment.
• History of another primary malignancy except for:
  • Malignancy treated with curative intent and with no known active disease ≥5 years before the first dose of IP and of low potential risk for recurrence.
  • Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.
  • Adequately treated carcinoma in situ without evidence of disease.
• Treatment with any investigational drug within 14 days prior to study registration.
• Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease \[e.g., colitis or Crohn's disease\], diverticulitis \[with the exception of diverticulosis\], celiac disease, irritable bowel disease, or other serious gastrointestinal chronic conditions associated with diarrhea, systemic lupus erythematosus, sarcoidosis syndrome, or Wegener syndrome \[granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc\]) within the last 3 years prior to study registration. The following are exceptions to this criterion: The following are exceptions to this criterion:
  • Subjects with vitiligo or alopecia.
  • Subjects with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement.
  • Any chronic skin condition that does not require systemic therapy.
  • Subjects without active disease in the last 5 years may be included but only after consultation with the study physician.
  • Subjects with celiac disease controlled by diet alone.
• Current or prior use of immunosuppressive medication within 28 days before the first dose of durvalumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. The following are exceptions to this criterion:
  • Intranasal, inhaled, topical steroids, or local steroid injections (eg, intra articular injection).
  • Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent.
  • Steroids as premedication for hypersensitivity reactions (eg, CT scan premedication).
• Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.
• Any concurrent chemotherapy, biologic or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g. hormone replacement therapy) is acceptable. Note: Local treatment of isolated lesions, excluding target lesions, for palliative intent is acceptable (e.g., local surgery or radiotherapy).
• Major surgical procedure (as defined by the Investigator) within 28 days prior to study registration. Note: local surgery of isolated lesions for palliative intent is acceptable.
• Receipt of live attenuated vaccine within 30 days prior to the first dose of study drug. Note: patients, if enrolled, should not receive live vaccine during the study and up to 30 days after the last dose of study drug.
• Female patients who are pregnant or breastfeeding or male or female patients of reproductive potential who are not willing to employ effective birth control from screening to 90 days after the last dose of study drug.

Other illness

• Active infection requiring systemic therapy.
• History of allogenic organ transplantation that requires use of immunosuppressive agents.
• Uncontrolled intercurrent illness including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent.
• History of leptomeningeal carcinomatosis.
• Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings), hepatitis B (known positive HBV surface antigen (HBsAg) result), hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies). Subjects with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody \[anti-HBc\] and absence of HBsAg) are eligible. Subjects positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
• Known allergy or hypersensitivity to study drugs or other humanized monoclonal antibodies.
• Past medical history of ILD, drug-induced ILD, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease.

Lab values

• Mean QT interval corrected for heart rate (QTc) ≥470 ms calculated from 3 electrocardiograms (ECGs) using Fridericia's Correction.
• Any unresolved toxicity NCI CTCAE Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria:
  • Subjects with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician.
  • Subjects with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician.

Other

• Subjects meeting any of the criteria below may not participate in the study:
• Pregnant or breastfeeding
• Involvement in the planning and/or conduct of the study (applies to both AstraZeneca/ MedImmune staff and/or staff at the study site).
• Patient ≤30kg in weight.

• Subject must meet all of the following applicable inclusion criteria to participate in this study:
• Written informed consent and HIPAA authorization for release of personal health information.
• ECOG Performance Status 0-1 within 28 days prior to registration.
• Histological diagnosis of clear cell renal cell carcinoma (pure or mixed) with radiologic or histologic evidence of metastatic disease.
• At least 1 lesion, not previously irradiated that can be accurately measured at baseline as ≥ 10 mm in the longest diameter (except lymph nodes which must have a short axis ≥ 15mm) with a computed tomography (CT) or magnetic resonance imaging (MRI) and that is suitable for accurate repeated measurements as per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST 1.1) guidelines.
• For cohort 1, subjects may have received up to 1 and no more than 1 prior line of systemic therapy (not counting any neoadjuvant/adjuvant therapy) including anti-VEGF, VEGFR inhibitor, MET inhibitor or mTOR inhibitor for metastatic disease. They cannot have received any prior anti-PD-1/PD-L1/CTLA4 therapy including durvalumab.
• For cohort 2, subjects may have received up to 2 prior systemic therapies which should include 1 (and only 1) prior anti-PD-1/PD-L1 therapy but did not have an objective response to the prior anti-PD-1/Pd-L1 therapy.
