What is the purpose of this trial?

This trial tests a new treatment called INCB123667 to determine its safety and effectiveness for people with advanced or metastatic solid tumors. Researchers will test it alone and in combination with other cancer-fighting medicines. The study has two parts: one focuses on finding the right dose, and the other explores different cancer types. People with certain cancers, such as breast, ovarian, or stomach cancer, who have not responded to other treatments, might be suitable candidates. As a Phase 1 trial, the research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive it.

Do I have to stop taking my current medications to join the trial?

The trial protocol does not specify if you must stop taking your current medications. However, you cannot have any change in endocrine therapy or take certain treatments within 28 days before starting the study drug.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that INCB123667 has a manageable safety profile. In a study with 84 patients with advanced solid tumors, the treatment was generally well-tolerated. Most side effects were mild or moderate, and no serious safety issues were reported. This suggests that INCB123667 could be a promising option for certain types of cancer. However, more information is needed to fully understand its safety and effectiveness. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about INCB123667 because it offers a unique approach to treating advanced or metastatic solid tumors. Unlike many current treatments that target tumor growth broadly, INCB123667 works by specifically interfering with key pathways involved in tumor cell survival. This targeted mechanism may provide more effective treatment with potentially fewer side effects. Additionally, the treatment is being tested in combination with other drugs like palbociclib, ribociclib, and olaparib, which could enhance its effectiveness against specific cancer types, such as HR+/HER2- breast cancer and gynecologic tumors. These combinations open up possibilities for personalized therapies that might work better than existing options.

What evidence suggests that this trial's treatments could be effective for solid tumors?

Research has shown that INCB123667, a CDK2 inhibitor, shows promise in early trials for treating advanced solid tumors. CDK2 inhibitors block a protein that aids cancer cell growth, potentially stopping tumor growth. In this trial, participants will receive INCB123667 in various treatment arms, each exploring different doses and combinations with other therapies. Early data suggests that INCB123667 affects tumors at different doses and treatment plans, potentially slowing or shrinking tumors in various cancer types. Initial results are encouraging, but further research is needed to confirm these findings. ^{1 2 3 4 6}

Published Research Related to This Trial

mTOR inhibitors, such as temsirolimus, are important in cancer treatment as they target dysregulated pathways involved in cell growth and proliferation, with temsirolimus being specifically approved for solid tumors.

Research is ongoing to better understand mTOR pathways and their role in various cancers, with studies exploring mTOR inhibition both as a standalone treatment and in combination with other therapies to combat drug resistance.

NCCN Task Force Report: mTOR inhibition in solid tumors. Figlin, RA., Brown, E., Armstrong, AJ., et al.[2021]

In a study of 435 cancer patients, RICTOR overexpression was found in 49% of solid tumors, indicating its potential role in promoting cancer cell proliferation and survival.

Immunohistochemistry (IHC) can effectively screen for RICTOR amplification, which was detected in 75.7% of IHC-positive cases, suggesting that IHC may be a valuable diagnostic tool for identifying tumors with RICTOR alterations.

Correlation between RICTOR overexpression and amplification in advanced solid tumors. Bang, H., Ahn, S., Ji Kim, E., et al.[2020]

In a study of eight breast cancer cell lines, six were sensitive to the mTOR inhibitor CCI-779, particularly those that were estrogen-dependent or lacked the tumor suppressor PTEN, indicating that mTOR is a promising target for treatment in these cases.

In mouse models, CCI-779 effectively inhibited the growth of sensitive tumors but not resistant ones, suggesting that the presence of certain molecular characteristics, like PTEN loss or Her-2/neu overexpression, can predict treatment response.

mTOR inhibitors like temsirolimus and everolimus have been shown to be effective in treating advanced renal cell carcinoma (RCC), with temsirolimus being FDA-approved for this use.

These inhibitors are also being evaluated for their potential effectiveness against various other cancer types, including breast cancer and leukemia, indicating their broad therapeutic potential in oncology.

Targeting tumorigenesis: development and use of mTOR inhibitors in cancer therapy. Yuan, R., Kay, A., Berg, WJ., et al.[2023]

mTOR dysregulation is a common feature in many tumors, leading to challenges in cancer treatment due to drug resistance and altered signaling pathways.

It is crucial to assess mTOR activity profiles in patients before using mTOR inhibitors, as first-generation inhibitors may not work effectively if mTORC2 is hyperactive; ongoing trials of new inhibitors show promise for advanced-stage patients selected based on molecular markers.
