• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: RaND Biosciences
• Treatments: Cisplatin

Criteria

Inclusion Criteria:

• Life expectancy ≥ 12 weeks.

• Histologically or cytologically confirmed NSCLC or BTC.

• At least 1 measurable target lesion ≥ 10 mm as measured by MRI or CT according to RECIST v1.1-criteria. Target lesions within the field of prior efficacy irradiation or in the area of local treatment (intervention or ablation therapy) are considered measurable in case of confirmation of progression.

• Optional availability of archival or fresh tumor specimen that is suitable for analysis. Acceptable samples must have been acquired from a surgical operation, using core needle biopsy, or excisional biopsy. Samples that were acquired using fine needle aspiration are not acceptable. Archival samples from the primary or recurrent cancer will have been taken within 5 years prior to screening. formalin fixed, paraffin-embedded tumor

• Presence of all the following clinical laboratory findings at screening:

• Absolute neutrophil count (ANC) ≥ 1.5 × 109/L, platelets ≥ 100 × 109/L, or hemoglobin ≥ 9 g/dL.

• Total bilirubin ≤ 1.5 × upper limit of normal (ULN) unless liver metastasis or BTC in which case ≤ 2.5 × ULN is permitted at the investigator's discretion.

• For BTC subjects, alkaline phosphatase and gamma-glutamyl transferase ≤ 5 × ULN.

• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN unless disease (NSCLC with liver metastases or BTC) related, in which case ≤ 5 × ULN is permitted at the investigator's discretion.

• Creatinine ≤ 1.5 × ULN, or calculated or measured creatinine clearance (CrCl) ≥ 60 mL/min as calculated by the Cockcroft-Gault method, or 24-hour measured urine CrCl ≥ 50 mL/min.

• Eastern Cooperative Oncology Group performance status < 2.

• For subjects with chronic hepatitis B or C

• If a female subject or a female spouse/partner of male subject is of childbearing potential, she must agree to use highly effective contraceptives from signing informed consent to 28 days or 5 half-lives of SC-43, whichever is the longest, after the last dose of study drug administration

• Male subjects should be willing to use a condom (with spermicidal foam/gel/film/cream/suppository) to prevent pregnancy and exposure of a female partner and should refrain from donating sperm or fathering a child from signing informed consent to 90 days after the last dose of study drug administration.

• Able to comprehend and willing to sign an informed consent form (ICF)

Exclusion Criteria:

• Clinically active or untreated central nervous system (CNS) metastases. Subjects with a history of treated CNS metastases that are asymptomatic are eligible.

• Malignancies other than NSCLC or BTC within 5 years prior to study enrollment, with the exception of those with a negligible risk of metastasis or death and treated with expected curative outcome (such as adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, localized prostate cancer treated with curative intent, or breast ductal carcinoma in situ treated surgically with curative intent).

• Any ≥ grade 2 (according to NCI-CTCAE v 5.0) AE at baseline (other than those previously allowed in the inclusion criteria).

• History of organ or tissue transplantation.

• History of autoimmune disease.

• Any serious acute, chronic infections that require systemic antimicrobial, antifungal, or antiviral therapy at screening, excluding viral hepatitis.

• History of human immunodeficiency virus infection.

• Significant cardiovascular disease, including:

• Heart disease classified as New York Heart Association class III or IV.

• Ongoing uncontrolled hypertension.

• History of congenital long QT syndrome.

• Ongoing prolonged QT interval corrected for heart rate using Fridericia's method (QTcF) defined as ≥ 470 msec.

• History of serious ventricular arrhythmia (ie, ventricular tachycardia or ventricular fibrillation).

• Subjects with atrial fibrillation, that is well controlled with treatment, can be enrolled.

• Ascertained hypersensitivity to any ingredient of SC-43 or drugs with similar chemical structures, including sorafenib. If there is suspicion that the subject may have an allergy, the subject should be excluded.

• Uncontrolled nausea or vomiting or any symptom that would prevent the ability to comply with daily oral SC-43 treatment

• Significant gastrointestinal disorder(s) within 12 weeks prior to screening that would, in the opinion of the investigator, prevent absorption of an orally available agent

• Active bleeding during the last 4 weeks prior to screening or in the investigator's judgment, the existence of high bleeding tendency lesions such as active gastrointestinal ulcers or prominent esophageal or gastric varices.

• Requirement for ongoing immunosuppressive agents (including azathioprine, mycophenolate, cyclophosphamide, chlorambucil, methotrexate, cyclosporine), or systemic steroid with equivalent dosage higher than prednisolone 30 mg/day for more than 14 days.

• Received an investigational agent within 4 weeks prior to screening.

• Had previous anticancer therapy (surgery, radiotherapy, chemotherapy, targeted therapy, immunotherapy, biological therapy, or hormonal therapy) within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to the first dose of SC-43
