Detailed Description

Study D6770C00001 is a Phase 1, first-in-human, multicenter, open-label, dose-escalation study to evaluate the safety, tolerability, antitumor activity, pharmacokinetics, and immunogenicity of IPH5201 in adult subjects with advanced solid tumors, when administered as monotherapy or in combination with durvalumab ± oleclumab.

    • Ascending dose levels of IPH5201 every 3 weeks (Q3W) for a maximum of 2 years
  • Biological: durvalumab
    • Durvalumab Q3W for a maximum of 2 years
  • Biological: oleclumab
    • Oleclumab Q3W for a maximum of 2 years

Arms, Groups and Cohorts

  • Experimental: IPH5201 monotherapy dose escalation
    • IPH5201 monotherapy
  • Experimental: IPH5201 dose escalation with durvalumab
    • IPH5201 plus durvalumab
  • Experimental: IPH5201 dose escalation with durvalumab + oleclumab
    • IPH5201 plus durvalumab and oleclumab

Clinical Trial Outcome Measures

Primary Measures

  • Incidence of adverse events as a measure of safety
    • Time Frame: From time of informed consent through treatment period and including the follow-up 12 weeks after last dose of investigational product, approximately 7 months
    • The primary endpoint is safety as assessed by the presence of adverse events (AEs), serious adverse events (SAEs), and dose limiting toxicities (DLTs).
  • Incidence of clinically significant laboratory values as a measure of safety
    • Time Frame: From time of informed consent through 12 weeks after the last dose of investigational product, approximately 7 months
    • Number of subjects with clinically significant laboratory values from baseline including blood counts, liver, kidney and pancreas tests, electrolytes, and blood clotting.
  • Incidence of clinically significant electrocardiogram (ECG) abnormalities as a measure of safety
    • Time Frame: From time of informed consent through treatment period and including the follow-up period 12 weeks after last dose of investigational product, approximatley 7 months
    • 12 lead ECGs will be measured to identify clinical significant abnormalities including ECGs that demonstrate a QTcF value >500ms, 2 additional 12-lead ECGs should be obtained over a 30 minute time period to confirm prolongation based on the average QTcF value

Secondary Measures

  • OR (Objective Response; Response evaluation criteria in solid tumors [RECIST] v1.1)
    • Time Frame: From time of consent until date of first documented disease progression (approximately 4 months)
    • Evaluate the primary antitumor activity of IPH5201 monotherapy or in combination with durvalumab +/- oleclumab (disease control)
  • DC (Disease Control; RECIST 1.1)
    • Time Frame: From time of consent until date of first documented disease progression (approximately 4 months)
    • Evaluate the primary antitumor activity of IPH5201 with durvalumab +/- oleclumab (disease control)
  • Half-life of IPH5201
    • Time Frame: From start of treatment through Cycle 6 (21 day cycle, approximately 5 months)
    • To characterize the pharmacokinetics of IPH5201 as monotherapy and in combination with durvalumab ± oleclumab
  • Maximum serum concentration (Cmax) of IPH5201
    • Time Frame: From start of treatment through Cycle 6 (21 day cycle, approximately 5 months)
    • To characterize the pharmacokinetics of IPH5201 as monotherapy and in combination with durvalumab ± oleclumab
  • Area under the curve (AUC) of IPH5201
    • Time Frame: From start of treatment through Cycle 6 (21 day cycle, approximately 5 months)
    • To characterize the pharmacokinetics of IPH5201 as monotherapy and in combination with durvalumab ± oleclumab
  • Serum trough concentrations (durvalumab)
    • Time Frame: From start of treatment through Cycle 6 (21 day cycle, approximately 5 months)
    • To determine the pharmacokinetics of durvalumab when administered in combination with IPH5201+/- oleclumab
  • Serum trough concentrations (oleclumab)
    • Time Frame: From start of treatment through Cycle 6 (21 day cycle, approximately 5 months)
    • To determine the pharmacokinetics of oleclumab in combination with durvalumab and IPH5201
  • Incidence of antidrug antibodies (IPH5201)
    • Time Frame: From start of treatment until 90 days after end of treatment (approximately 7 months)
    • To determine the immunogenicity of IPH5201 as monotherapy and in combination with durvalumab ± oleclumab
  • Incidence of antidrug antibodies (durvalumab)
    • Time Frame: From start of treatment until 90 days after end of treatment (approximately 7 months)
    • To determine the immunogenicity of durvalumab in combination with IPH5201 ± oleclumab
