This is a multicenter, open-label, phase I/IIa to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary antitumor activity of pan-KRAS inhibitor JAB-23E73 in patients with advanced solid tumors harboring KRAS mutations or amplification. The study consists of 2 phases: Phase 1 Dose Escalation and Phase IIa Dose Expansion.
Study JAB-23E73-1001 is a global multicenter, open-label Phase 1/2a study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anticancer activity of JAB-23E73 as a single agent in adult patients with advanced solid tumors with KRAS alteration. This study consists of a Phase 1a dose-escalation, followed by Phase 1b dose-expansion (dose optimization) and Phase 2a indication expansion. After completing dose-escalation, the MTD or preliminary RP2D of JAB-23E73 will be determined. Then, two of the alternative dosages of JAB-23E73 will be selected to further evaluate the efficacy, safety and PK in patients with KRAS-alternated NSCLC or other tumors, and patients may be further selected by certain/several types of KRAS-alternations based on dose escalation data. The RP2D will be determined according to the safety, efficacy and PK data from phase 1b.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.

ECOG performance status
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

Started Nov 2024 (actual). Primary completion is estimated for Dec 2026, 25 months after the start.
Of 115 industry-sponsored phase 1/2 interventional studies under Pancreatic Neoplasms, half reached primary completion within 47 months of starting (the median), counting those still running; a quarter within 34 and three quarters within 88. This study's planned 25 months is below that.
Counting every sponsor, half of 209 studies reached it within 51 months; a quarter within 36 and three quarters within 89.
