What this study is about
This study is to evaluate the safety and how well patients handle the treatment of JAB-2485 treatment given alone in adult participants with advanced solid tumors.
View original scientific description
This study is to evaluate the safety and tolerability of JAB-2485 monotherapy in adult participants with advanced solid tumors.
Interventions
DRUG
JAB-2485 (Aurora A inhibitor)
Administered orally
DRUG
JAB-2485 (Aurora A inhibitor)
Administered orally
Primary outcome measures
Dose Escalation phase: Number of participants with dose limiting toxicities (DLTs)
Time frame: First 21 days of Cycle 1
A DLT is defined as an adverse event (AE) regardless of attribution unless clearly related to underlying disease or extraneous cause during the first 21 days of Cycle 1 (DLT observation period).
Dose Escalation phase: Number of participants with adverse events (AEs)
Time frame: Up to 3 years
Participants will be assessed for incidence and severity of AEs according to NCI-CTCAE v5.0
Dose Expansion phase: Objective Response Rate (ORR)
Time frame: Up to 3 years from baseline to RECIST confirmed Progressive Disease (PD)
ORR is defined as the percentage of participants with partial response (PR) or complete response (CR) based on RECIST v1.1
Dose Expansion phase: Duration of Response (DOR)
Time frame: Up to 3 years
DOR is defined as the time from the participants initial objective response (CR or PR) to disease progression per CTCAE v1.1 or death due to any cause, whichever occurs first.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
