Investigating GenSci122 for advanced solid tumors

A Phase I Study of Safety, Tolerability, Pharmacokinetics and Preliminary Anti-Tumor Activity of the Oral KIF18A Inhibitor GenSci122 in Participants With Advanced Solid Tumors

This study is testing a new medication called GenSci122 to see if it is safe and effective for people with advanced solid tumors.

What this trial studies

This is a first-in-human, multicenter, open-label phase I study designed to evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of GenSci122 in participants with advanced solid tumors. The study is divided into two parts: a dose-escalation phase to assess safety and tolerability, and a dose-expansion phase to evaluate the preliminary anti-tumor activity of GenSci122. Participants will receive either a 50mg or 250mg tablet of GenSci122, and their responses will be closely monitored.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with recurrent or metastatic advanced solid tumors who have failed or are intolerant to standard treatments.

Not a fit: Patients with early-stage tumors or those who have not yet received standard treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced solid tumors who have exhausted standard therapies.

How similar studies have performed: Other studies investigating similar novel therapies for advanced solid tumors have shown promising results, indicating potential for success in this approach.

9. All toxicity related to prior cancer therapies must have resolved to ≤ Grade 1
10. Congestive heart failure (CHF), which must have been ≤ Grade 1 in severity at the time of occurrence and must have resolved completely.
11. Normal QT interval on screening ECG evaluation
12. Participants with a known HIV infection are eligible if the following criteria are met:

    a. Stable on antiretroviral therapy for ≥ 4 weeks before the first dose of GenSci122.

    d. Viral load of \< 400 copies per mL at screening. e. CD4+ T-cell count ≥ 350 cells/μL at screening.
13. Hepatitis B virus (HBV) and hepatitis C virus (HCV) test is negative. If participants have active HBV infection: HBV- deoxyribonucleic acid (DNA) must be \< 500 IU/mL (or must be \< 2500 copy/mL if copy/mL is the only unit available in the study site) and are willing to receive antiviral therapy throughout the study (treatment in accordance with local standard of care, e.g., entecavir); participants with positive HCV ribonucleic acid (RNA) must receive antiviral therapy in accordance with the local standard treatment guideline and have ≤ CTCAE 5.0 Grade 1 elevated hepatic function.
14. Women of childbearing potential (WOCBP) must have a serum pregnancy test negative within 7 days before the first dose of GenSci122. WOCBP must agree to avoid pregnancy during the study and agree to the use 2 effective contraceptive methods (hormonal or barrier method of birth control, or abstinence) before study entry, for the duration of study participation, and in the following 6 months after discontinuation of Gensci122
15. Men with a partner(s) of childbearing potential must take appropriate precautions to avoid fathering a child from screening until 3 months after discontinuation of GenSci122 and to use appropriate barrier contraception or abstinence

Exclusion Criteria:

1. Investigational agent or anticancer therapy within 5 half-lives or 4 weeks (whichever is shorter) before the first dose of GenSci122. In addition, no concurrent investigational anti-cancer therapy is permitted.
2. Major surgery (excluding placement of vascular access) within 4 weeks before the first dose of GenSci122.
3. Radiotherapy within 4 weeks before the first dose of GenSci122. Or participants have not yet recovered from acute effects of radiotherapy to baseline before the first dose of GenSci122.
4. Symptomatic primary central nervous system (CNS) tumor, metastases, leptomeningeal carcinomatosis, or untreated spinal cord compression.
5. Clinically significant active cardiovascular disease or history of myocardial infarction within 6 months before the first dose of GenSci122.
6. Active uncontrolled systemic bacterial, viral, or fungal infection, or serious ongoing intercurrent illness, such as hypertension or diabetes, despite optimal treatment. Screening for chronic conditions is not required.
7. Inability to swallow pills or clinically significant active malabsorption syndrome or other condition likely to affect gastrointestinal absorption of GenSci122.
8. Pregnancy or lactation.
9. History of previous cancer, except for squamous cell or basal-cell carcinoma of the skin, or any in situ carcinoma, for which by the date of the first dose of GenSci122, at least 3 years of complete remission and no other treatment is needed or expected during the study period.
10. Clinically significant history of liver disease, including viral or other hepatitis, current alcohol abuse
11. Allergic to GenSci122 tablet or its components.
12. Any serious illness, uncontrolled inter-current illness, psychiatric illness, or other medical history, including lab results, which in the opinion of investigator or medical monitor would be likely to impact safety or compliance with study requirements or confounds the ability to interpret the data.
13. Has a treatment history of KIF18A inhibitor.
