Overview
Brief Summary
The purpose of this study is to assess the safety and tolerability and to determine the dose of IPH5201 that can be used as monotherapy or in combination with durvalumab +/- oleclumab in subjects with advanced solid tumors.
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.

Eligibility Criteria
Inclusion Criteria

- •Subjects diagnosed with advanced solid tumors.
- •For Part 1 and Part 2 (IPH5201 in monotherapy or combined with durvalumab):Subjects must be refractory to standard therapy or for which no standard therapy exists.
- •For Part 3 (IPH5201 combined with durvalumab and oleclumab): Subjects must have received and radiologically progressed on 1 prior line of systemic therapy for metastatic pancreatic ductal adenocarcinoma.
- •Subjects must have at least 1 measurable lesion according to RECIST v1.
- •Subjects must provide tumor specimens .
Exclusion Criteria
- •Receipt of any conventional or investigational anticancer therapy (anti-CTLA-4, anti-PD-1, anti-PD-L1 antibodies) within 21 days of the planned first dose.
- •Receipt of agents targeting CD73, CD39, or adenosine receptors.
- •Concurrent enrollment in another therapeutic clinical study.
- •Any toxicity (excluding alopecia) from prior standard therapy that has not been completely resolved to baseline at the time of consent.
- •No toxicity leading to permanent discontinuation of prior IO therapy
- •Subjects must not have required the use of additional immunosuppression other than corticosteroids
- •Active or prior documented autoimmune or inflammatory disorders within the past 5 years
- •Cardiac and vascular criteria:

Outcomes
Primary Outcomes
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 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
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.
Secondary Outcomes
- OR (Objective Response; Response evaluation criteria in solid tumors [RECIST] v1.1)(From time of consent until date of first documented disease progression (approximately 4 months))
- Maximum serum concentration (Cmax) of IPH5201(From start of treatment through Cycle 6 (21 day cycle, approximately 5 months))
- Half-life of IPH5201(From start of treatment through Cycle 6 (21 day cycle, approximately 5 months))
- DC (Disease Control; RECIST 1.1)(From time of consent until date of first documented disease progression (approximately 4 months))
- Area under the curve (AUC) of IPH5201(From start of treatment through Cycle 6 (21 day cycle, approximately 5 months))
- Serum trough concentrations (oleclumab)(From start of treatment through Cycle 6 (21 day cycle, approximately 5 months))
- Incidence of antidrug antibodies (IPH5201)(From start of treatment until 90 days after end of treatment (approximately 7 months))
- Incidence of antidrug antibodies (oleclumab)(From start of treatment until 90 days after end of treatment (approximately 7 months))
- Serum trough concentrations (durvalumab)(From start of treatment through Cycle 6 (21 day cycle, approximately 5 months))
- Incidence of antidrug antibodies (durvalumab)(From start of treatment until 90 days after end of treatment (approximately 7 months))
