Phase I-II
Study of ARTS-021 in Patients With Advanced Solid Tumors
- Study HIC#:2000035922
- Last Updated:10/17/2024
This study, the first clinical trial of ARTS-021, aims to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, maximum tolerated dose, and anti-tumor effects of ARTS-021 in patients with advanced solid tumors. ARTS-021 is an oral medication that inhibits cyclin-dependent kinase 2 (CDK 2).

Measurable or nonmeasurable disease as determined by RECIST version 1.1 as appropriate by tumor type. Exclusion Criteria: A patient who meets any of the following exclusion criteria will not be eligible for inclusion in the study: All patients 1. Have received an investigational agent or anticancer therapy within 2 weeks prior to planned start of ARTS-021. 2. Have received any CDK2 inhibitor, protein kinase membrane associated tyrosine/threonine 1 (PKMYT1) inhibitor, or WEE1 inhibitor anticancer therapy. 3. Have undergone major surgery within 4 weeks prior to planned start of ARTS-021. 4. Have received radiotherapy with a limited field of radiation for palliation within 7 days of the first dose of study treatment, except for patients receiving whole brain radiotherapy, which must be completed at least 4 weeks prior to the first dose of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1 week washout is permitted for palliative radiation with a limited port ≤ 2 weeks of radiotherapy to noncentral nervous system (CNS) disease. 5. Active CNS metastases are not eligible. Patients with asymptomatic and treated brain metastases may participate if they are stable and are not requiring steroid treatment. Patients with suspected or confirmed leptomeningeal disease are not eligible even if treated. 6. Have any unresolved toxicities from prior therapy greater than Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 Grade >1 at the time of starting study treatment except for alopecia of any grade or Grade 2 peripheral neuropathy. 7. Have clinically significant, active cardiovascular disease or history of myocardial infarction within 6 months prior to planned start of ARTS-021, or prolongation of the QT interval corrected for heart rate (QTcF) > 470 msec on at least 2/3 consecutive electrocardiograms (ECGs), and mean QTcF > 470 msec on all 3 ECGs, during screening. QTcF is calculated using Fridericia's formula (QTcF): QTcF = QT RR0.33 Correction of suspected drug-induced QTcF prolongation can be attempted at the investigator's discretion and only if clinically safe to do so with either discontinuation of the offending drug or switch to another drug not known to be associated with QTcF prolongation. 8. Have immunodeficiency or chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior the first dose of study drug. Inhaled or topical steroids are permitted in the absence of active autoimmune disease. 9. Have active uncontrolled systemic bacterial, viral, fungal, or parasitic infection (except for fungal nail infection), or coronavirus disease 2019 (COVID-19) infection, or other clinically significant active disease process which in the opinion of the investigator and the sponsor makes it undesirable for the patient to participate in the trial. Screening for chronic conditions is not required. 10. Have active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. Note: Controlled (treated) hepatitis will be allowed if they meet the following criteria, antiviral therapy for HBV must be given for at least 1 month prior to first dose of study drug, and HBV viral load must be less than 2000 IU/mL (104 copies/mL) prior to the first dose of study drug. Those on active HBV therapy with viral loads below 2000 IU/mL (104 copies/mL) should stay on the same therapy throughout the study treatment. Note: Untreated patients with chronic infection by HCV are allowed on study. In addition, successfully treated patients (defined as sustained virologic response SVR12 or SVR24) are allowed, if there are 4 weeks between achieving sustained viral response (SVR12 or SVR24) and starting study drug. 11. Have known HIV; excluded due to potential drug-drug interactions between antiretroviral medications and ARTS-021. 12. Current treatment with strong or moderate cytochrome P450 (CYP)3A4 inhibitors or inducers. 13. Have clinically significant active malabsorption syndrome or other condition likely to affect gastrointestinal absorption of the study drug. 14. Have active second malignancy unless in remission with life expectancy > 2 years and with documented sponsor approval. Examples include: 1. Adequately treated nonmelanomatous skin cancer or lentigo maligna melanoma without current evidence of disease. 2. Adequately treated cervical carcinoma in situ without current evidence of disease. 3. Localized (eg, lymph node negative) breast cancer treated with curative intent with no evidence of active disease present for more than 5 years. 4. Localized prostate cancer undergoing active surveillance. 15. Pregnancy, lactation, or plans to breastfeed during the study or within 3 months of the last dose of study intervention. 16. Have known hypersensitivity to any component of ARTS-021, its formulation, or any combination drug (palbociclib, fulvestrant, letrozole, or carboplatin) for patients in the combination therapy (Part 1b and Part 2b). 17. Have clinically significant gastrointestinal abnormality affecting digestive function that in the opinion of the investigator would affect study drug therapy.
