Trial Summary

What is the purpose of this trial?

In this clinical trial, the safety, tolerability, and preliminary antitumor activity of ziftomenib in combination with imatinib will be evaluated in adults with gastrointestinal stromal tumors (GIST) who have been treated previously with imatinib.

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications, but you cannot have taken any prohibited medications, including investigational therapies, less than 14 days before starting the study.

What data supports the effectiveness of the drug combination Ziftomenib + Imatinib for GIST?

Imatinib has been shown to significantly change the treatment and prognosis of gastrointestinal stromal tumors (GISTs) by effectively targeting the disease, especially in cases that are intermediate- and high-risk, as well as locally advanced and metastatic. This suggests that combining it with another drug like Ziftomenib could potentially enhance its effectiveness.12345

Is the combination of Ziftomenib and Imatinib safe for treating GIST?

Imatinib, used for treating gastrointestinal stromal tumors (GIST), is generally well tolerated with most side effects being mild, such as muscle cramps and gastrointestinal symptoms. Severe side effects are rare and usually occur early in treatment. There is no specific safety data available for Ziftomenib in this context.16789

What makes the drug Ziftomenib + Imatinib unique for treating GIST?

Ziftomenib + Imatinib is unique because it combines two drugs that target different pathways involved in gastrointestinal stromal tumor (GIST) growth, potentially overcoming resistance seen with Imatinib alone. This combination may enhance the effectiveness of treatment by addressing multiple mechanisms that tumors use to survive.23101112

Eligibility Criteria

This trial is for adults with advanced GIST who have a specific mutation (KIT mutant) and whose disease got worse despite being treated with imatinib. They should be relatively active (ECOG ≤2), not pregnant, have at least one tumor that can be measured, good organ function, and recovered from previous treatments.

Inclusion Criteria

I can understand and sign the consent form myself or have someone legally allowed to do it for me.
I have at least one tumor that can be measured.
My organs are functioning well.

Treatment Details

Interventions

  • Imatinib
  • Ziftomenib
Trial Overview The trial tests the combination of ziftomenib, an oral drug that inhibits a protein called menin, with imatinib to see if it's safe and effective against GIST tumors in patients who've already tried imatinib alone.

Findings from Research

Imatinib, a tyrosine kinase inhibitor, has significantly improved the prognosis for patients with chronic myeloid leukaemia (CML) and gastrointestinal stromal tumours (GIST), showing high rates of cytogenetic and molecular responses across all phases of CML.
The drug is well tolerated, with only mild adverse effects such as joint pain and gastrointestinal symptoms, primarily occurring in the first two years of treatment, making it a safe and effective oral option for these cancers.
A benefit-risk assessment of imatinib in chronic myeloid leukaemia and gastrointestinal stromal tumours.Wolf, D., Rumpold, H.[2021]
Imatinib mesylate is the standard first-line treatment for chronic myeloid leukaemia (CML) and gastrointestinal stromal tumour (GIST), effectively targeting specific tyrosine kinases and significantly improving patient prognosis.
The treatment is generally well tolerated with a low risk of severe side effects, and long-term use shows excellent tolerability, with concerns like cardiotoxicity being largely exaggerated.
The safety profile of imatinib in CML and GIST: long-term considerations.Thanopoulou, E., Judson, I.[2015]
Imatinib mesylate has shown a high clinical response rate of 81.6% in patients with gastrointestinal stromal tumors (GIST), with 53.7% achieving a partial response and 27.9% having stable disease.
While most patients experienced only mild toxicities (grade 1 or 2), 21.1% had more severe side effects (grade 3 or higher), indicating that imatinib is relatively safe but can still cause significant adverse effects.
