Drug Information available for: Durvalumab

Arm Intervention/treatment
Experimental: Sequential
MEDI5395 and durvalumab administered sequentially
Biological: MEDI5395
Subjects will receive multiple doses of MEDI5395 over several days.

Biological: Durvalumab
Durvalumab will be administered periodically for a maximum of 2 years or until radiologically confirmed disease progression, clinical deterioration, withdrawal of consent, or unacceptable toxicity
Other Name: Imfinzi

Experimental: Concurrent
MEDI5395 and durvalumab administered concurrently
Biological: MEDI5395
Subjects will receive multiple doses of MEDI5395 over several days.

Biological: Durvalumab
Durvalumab will be administered periodically for a maximum of 2 years or until radiologically confirmed disease progression, clinical deterioration, withdrawal of consent, or unacceptable toxicity
Other Name: Imfinzi




Primary Outcome Measures :
  1. Number of subjects with adverse events (AEs) serious adverse events (SAEs) and dose limiting toxicities (DLTs). [ Time Frame: From the time of informed consent until 90 days after the last dose of investigational product (MEDI5395 or durvalumab) ]
    The occurrence of DLTs will be used to establish the maximum tolerated dose (MTD) of MEDI5395.


Secondary Outcome Measures :
  1. Objective response rate (ORR) [ Time Frame: Estimated to be from the time of informed consent for approximately 2.5 years ]
    The ORR is defined as the proportion of subjects with confirmed response (CR) or confirmed partial response (PR).

  2. Disease Control Rate (DCR) [ Time Frame: Estimated to be from the time of informed consent for approximately 2.5 years ]
    The DCR will be estimated by the proportion of disease control. Disease control is defined as CR, PR or stable disease.

  3. Duration of Response (DoR) [ Time Frame: Estimated to be from the time of informed consent for approximately 2.5 years ]
    The DoR is defined as the duration from the first documentation of objective response to the first documented disease progression or death due to any cause, whichever occurs first.

  4. Time To Response (TTR) [ Time Frame: Estimated to be from the time of informed consent for approximately 2.5 years ]
    The TTR is defined as the time from the start of treatment with any investigational product until the first documentation of a subsequently confirmed objective response.

  5. Progression Free Survival (PFS) [ Time Frame: Estimated to be from the time of informed consent for approximately 2.5 years ]
    PFS will be measured from the start of treatment with any investigational product until the first documentation of disease progression or death due to any cause, whichever occurs first.

  6. Overall Survival (OS) [ Time Frame: Estimated to be from the time of informed consent for approximately 2.5 years ]
    OS will be measured from the start of treatment with investigational product until death due to any cause.

  7. MEDI5395 viral genome copies in blood collected over time [ Time Frame: Estimated to be from the time of informed consent for approximately 6 months ]
    MEDI5395 concentrations in blood will be tabulated by dose cohort along with descriptive statistics.

  8. Granulocyte-macrophage colony-stimulating factor (GM-CSF) concentrations in blood collected over time [ Time Frame: Estimated to be from the time of informed consent for approximately 6 months ]
    GM-CSF protein concentrations in blood will be tabulated by dose cohort along with descriptive statistics.

  9. Number of subjects who develop detectable anti-MEDI5395 neutralizing antibodies [ Time Frame: Estimated to be from the time of informed consent until approximately 90 days after the last dose of last investigational product ]
    Immunogenic response to MEDI5395 will be assessed by summarizing the number of subjects who develop detectable anti-MEDI5395 neutralizing antibodies

  10. Percentage of subjects who develop detectable anti-MEDI5395 neutralizing antibodies [ Time Frame: Estimated to be from the time of informed consent until approximately 90 days after the last dose of last investigational product ]
    Immunogenic response to MEDI5395 will be assessed by summarizing the percentage of subjects who develop detectable anti-MEDI5395 neutralizing antibodies

  11. The number of cluster of differentiation 8 (CD8) positive cells and programmed death-ligand 1(PD-L1) expressing cells within biopsies will be assessed. [ Time Frame: Estimated to be from the time of informed consent until 4 weeks after the first dose of MEDI5395 ]
    CD8 T cell infiltration and PD-L1 expression in tumors pre and post dosing will be assessed using validated IHC assays.

Criteria

Inclusion Criteria

  • The subject must consent to take precautionary measures to prevent Newcastle Disease Virus (NDV) transmission to humans and birds
  • Subjects must have histologic documentation of advanced solid tumor and received and have progressed, are refractory, or are intolerant to standard therapy for the specific tumor type. All subjects are required to have had at least one prior line of treatment in the recurrent or metastatic setting
  • Subjects must have at least 1 measurable lesion
  • All subjects must consent to provide tumor tissue for correlative studies
  • ECOG performance status of 0 to 1

Exclusion Criteria

  • Rapidly progressing disease defined as a subject that cannot tolerate a break of at least 8 weeks from systemic anticancer therapy.
  • Primary central nervous system (CNS) disease is excluded
  • Subjects who have received prior immunotherapy will require varying washout times prior to the first dose of MEDI5395
  • Unresolved toxicities from prior anticancer therapy
  • History of severe allergic reactions to any of the study drug components
  • Infectious disease exclusions including tuberculosis, Human immunodeficiency virus (HIV), hepatitis A, B or C, active bacterial, fungal or viral infections plus receipt of live attenuated vaccine prior to first dose of MEDI5395. (NOTE: Subjects with evidence of fully recovered past hepatitis B infection who developed immunity OR hepatitis B/C with undetectable virus load and are on medications may be permitted).
  • Any conditions requiring use of any systemic immunosuppressant including systemic corticosteroids, methotrexate, azathioprine, tumor necrosis factor (TNF) inhibitor, and/or interleukin 6 (IL-6) blockers
  • Active autoimmune disease or chronic inflammatory condition (Exceptions include vitiligo, alopecia, hypothyroidism on stable treatment, diverticulosis, controlled celiac disease and chronic skin conditions not requiring systemic therapy)
  • Active acquired immune-deficiency states
  • Subjects who are regularly exposed to poultry or birds
  • Current active hepatitis or biliary disease (except for Gilbert's syndrome, asymptomatic gallstones, or stable chronic liver disease)
  • Clinically significant pulmonary disease and cardiac disease
  • Any condition that, in the opinion of the investigator, would interfere with evaluation of the investigational product or interpretation of subject safety or study results.
