A Phase 2 interventional study of REC-4881 in AXIN1 Gene Mutation, APC Gene Mutation and Solid Tumor, sponsored by Recursion Pharmaceuticals Inc.. Terminated at 13 sites in United States. Open to participants aged 55 Years and older. Per ClinicalTrials.gov, last updated 2026-02-23.
Sponsored by Recursion Pharmaceuticals Inc. · Phase 2, Interventional, and Treatment
This is a multi-center, open-label study to investigate the safety, efficacy and pharmacokinetics of REC-4881 (12 mg PO daily doses) for the treatment of participants with unresectable locally advanced or metastatic solid tumors with AXIN1 or APC mutation.
4,040 studies on the registry are indexed under Neoplasm Metastasis; 886 are open to participants now.
This study's enrollment of 18 is below the median of 50 across 3,268 interventional studies indexed under Neoplasm Metastasis.

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.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
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.
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 share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
