About
This is a phase Ib trial with SAR439459, a TGF-beta inhibitor, in combination with cemiplimab, a PD-L1 inhibitor, in patients with solid tumors that have spread to other places in the body (advanced) or cannot be removed by surgery (unresectable). Inhibiting TGF-beta may interfere with the ability of cancer cells to grow and spread and may sensitize cancers to immune checkpoint inhibitor therapy. The objective of this study is to determine whether this drug combination is effective in shrinking cancers, keeping them from growing, helping patients live longer, and to see if the drug combination is safe.
Full description
PRIMARY OBJECTIVE:
I. To assess the anti-tumor activity of the combination of anti-TGF-beta monoclonal antibody SAR-439459 (SAR439459) and cemiplimab in patients with advanced solid tumors.
SECONDARY OBJECTIVES:
I. To confirm the safety and tolerability of the combination of SAR439459 and cemiplimab in patients with advanced solid tumors.
II. To evaluate the overall response rate (ORR), progression-free survival (PFS), median overall survival (OS) and duration of response (DoR).
III. To identify biomarkers of response and resistance to the combination of SAR439459 and cemiplimab in patients with advanced solid tumors.
OUTLINE:
Patients receive SAR439459 intravenously (IV) over 30 minutes on day 1 and cemiplimab IV over 30 minutes on day 1 starting cycle 2. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30, 60, and 90 days, then every 12 weeks until progression of disease is determined or patient receives additional anti-neoplastic medication.

Inclusion criteria
-
Patients must have a histologically confirmed, advanced unresectable or metastatic solid tumor whom in the opinion of the Investigator do not have a suitable alternative therapy
-
Disease must be measurable by Response Evaluation Criteria in Solid Tumors (RECIST 1.1), and safely undergo serial tumor biopsies. For patients with castration-resistant prostate cancer, evaluable disease by Prostate Cancer Working Group 3 (PCWG3) will be permitted if serial biopsies (e.g. bone tumor biopsies) are feasible
-
Patients must have previously received a PD-1 or PD-L1 inhibitor-based therapy and must have achieved stable disease (SD) for at least 6 months, or complete remission/partial remission (CR/PR) prior to disease progression (secondary resistance) by radiological assessment by the study investigator. The PD-1 or PD-L1 inhibitor-based therapy must be the immediate line of treatment prior to study enrollment
-
Patients must have adequate functional status as defined by Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1

Platelets >= 100,000 / mcL
-
Hemoglobin >= 9.0 g/dL
-
Serum creatinine =< 1.5 x upper limit of normal (ULN) OR measured or calculated creatinine clearance (glomerular filtration rate [GFR] can also be used in place of creatinine or creatinine clearance [CrCl]) >= 60 mL/min for subject with creatinine levels > 1.5 x institutional ULN (creatinine clearance should be calculated per institutional standard)
-
Serum total bilirubin =< 1.5 x ULN OR direct bilirubin =< ULN for subjects with total bilirubin levels >= 1.5 x ULN
-
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x ULN OR =< 5 x ULN for subjects with liver metastases
-
International normalized ratio (INR) or prothrombin time (PT) =< 1.5 x ULN
-
Activated partial thromboplastin time (aPTT) =< 1.5 x ULN
-
Patients must have discontinued all previous systemic cancer treatments for at least 21 days and recovered from the acute toxic effects of therapy to grade < 1 per Common Terminology Criteria for Adverse Events (CTCAE) v5.0, excluding persistent grade 2 or higher toxicities determined to be clinically insignificant per the principal investigator (PI) (i.e. alopecia or grade 2 neuropathy). Patients must have discontinued from previous treatments as shown below:
-
Cytotoxic therapies or targeted agents that are small-molecule inhibitors >= 3 weeks prior to (study entry/enrollment/first dose of study treatment)
-
Mitomycin C or nitrosoureas >= 42 days prior to (study entry/enrollment/first dose of study treatment)
-
Biologic agents (e.g., antibodies) >= 3 weeks prior to (study entry/enrollment/first dose of study treatment)
-
Immunotherapy (e.g., CTLA4, PD-1, PDL1 inhibitors) >= 3 weeks prior to (study entry/enrollment/first dose of study treatment)
-
Radiotherapy >= 4 weeks prior to (study entry/enrollment/first dose of study treatment)
-
Limited field radiotherapy or palliative radiotherapy >= 3 weeks prior to (study entry/enrollment/first dose of study treatment)
-
Major surgery, excluding biopsy: Patients with recent major surgery must have recovered, in the opinion of the investigator, from the toxicity and/or complication from the intervention before starting therapy
-
Study drug with an investigational product, or non-approved use of a drug or device >= 3 weeks prior to (study entry/enrollment/first dose of study treatment)
- If the patient was treated with an agent with a short half-life, washout can be < 3 weeks but no shorter than 5 times the half-life
-

Patients should not become pregnant or breastfeed while on this study. Sexually active patients must agree to use dual contraception for the duration of study participation and for at least 6 months for females and 3 months for males after. Males should not donate sperm during the study and for 3 months after your last dose of study drugs
