DECOY20 Study in Patients With Advanced Solid Tumors

INDP-D101 is a Phase 1, open-label, multi-center, dose escalation and expansion study evaluating the safety, tolerability and clinical activity of Decoy20 in patients with advanced solid tumors.

Inclusion Criteria:Males or females, age 18 years or older.Histologically confirmed diagnosis of an advanced metastatic solid tumor.Subject has received at least 1 and up to 3 lines of prior therapy in the metastatic setting, and then progressed (recurred, relapsed or are refractory) or has been intolerant.Measurable disease (at least 1 measurable lesion) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 as defined by tumor type.Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.Life expectancy of at least 3 months.Female subjects must be of non-childbearing potential (surgically sterile or at least 2 years postmenopausal) or agree to use a highly effective contraception method while receiving treatment with Decoy20 and for 30 days after the last dose of Decoy20.Male subjects must utilize reliable contraceptive precautions for the duration of Decoy20 treatment and 30 days after the last dose of Decoy20.Adequate organ function as demonstrated by baseline laboratory assessmentLeft ventricular ejection fraction (LVEF) ≥ 45% by echocardiogram (ECHO) or multi gated acquisition scan (MUGA).Recovered from toxicities due to prior therapies.Exclusion Criteria:Pregnant or lactating females.Has an active systemic (viral, bacterial, or fungal) infection or requiring treatment.Received radiotherapy within 28 days of the first dose of Decoy20. Subjects must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis.Received prior chemotherapy, immunotherapy, or major immunomodulatory therapy within 28 days or 5 half-lives from W1D1. If prior treatment with a programed cell death 1 (PD-1) or programed cell death ligand 1 (PD-L1) inhibitor within 2 months prior to eligibility.Received systemic corticosteroid therapy > 5 mg/day of prednisone or equivalent dose of another corticosteroid within 1 week or 5 half-lives (whichever is shorter) from the start of study drug or is expected to require it during the course of the study (topical and inhaled steroids are permitted).Has radiographically detected primary central nervous system (CNS) metastases or symptomatic CNS involvement (including leptomeningeal carcinomatosis, cranial neuropathies or mass lesions that cause spinal cord compression).Clinical evidence of significant coagulopathy during Screening (e.g., deep vein thrombosis or pulmonary embolism) or history of significant uncontrolled coagulopathy.Has an active secondary malignancy in addition to the primary, excluding low-risk neoplasms as determined by the Investigator (e.g., non-metastatic basal cell or squamous cell skin carcinoma).Has a history of or active infection with Human Immunodeficiency Virus 1 or 2, positive read for Hepatitis B virus antibodies or surface antigen or positive read for Hepatitis C ribonucleic acid detected by qualitative assay.Known intolerance to non-steroidal anti-inflammatory drugs (NSAIDs).Has a history of known genetic predisposition to HLH/MAS.Has undergone splenectomy, has an active chronic liver disease, alcoholic liver disease, Wilson's disease, hemochromatosis, primary biliary cirrhosis, primary sclerosing cholangitis, genetic hemochromatosis, history of or planned liver transplant for end-stage liver disease of any etiology, documented history of advanced liver fibrosis or history of cirrhosis and/or hepatic decompensation including ascites, hepatic encephalopathy, or variceal bleeding.Has received a live vaccine within 28 days of W1D1.Has active autoimmune disease.Has a history of significant CNS disease, such as stroke or uncontrolled and unstable epilepsy.Has severe pulmonary interstitial disease and/or oxygen saturation on room air < 92%.Baseline Q-T correlated (QTc) interval of > 470 msec for females and > 450 msec for males calculated using Fridericia's formula.New York Heart Association Class III or IV cardiac disease, or myocardial ischemia or infarction within 180 days of Screening, severe unstable angina, coronary/peripheral artery bypass graft, worsening/decompensated heart failure within the past 6 months, or any other clinically significant cardiac abnormality that, in the judgement of the I Investigator, would pose a health risk to the subject.Major surgical procedure within 4 weeks prior to first dose of Decoy20, or anticipation of need for a major surgical procedure, during the study.Any other acute or chronic medical or psychiatric condition that may increase the risk associated with study participation or Decoy20 administration.Has received investigational therapy within 28 days or 5 half-lives of the start of study drug.Unwillingness or inability to comply with procedures required in this protocol.Known allergy or hypersensitivity to Decoy20 or one of the ingredients of Decoy20.
