What is the purpose of this trial?

This trial tests a new drug, STK-012, both alone and with other cancer drugs like pembrolizumab (KEYTRUDA), to determine its safety and effectiveness for advanced solid tumors. The trial includes different parts: some use STK-012 alone, while others combine it with pembrolizumab and other chemotherapy drugs. It targets individuals whose cancer has worsened after standard treatments or who cannot tolerate or choose to avoid those treatments. Those with specific types of tumors, particularly if untreated for metastatic disease, might be suitable for this trial. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering the opportunity to be among the first to receive this new drug.

Will I have to stop taking my current medications?

The trial requires that you stop taking any systemic anti-cancer therapy at least 3 weeks before starting the study treatment. If you are taking small molecule kinase inhibitors, you must stop them within 6 elimination half-lives before the first dose. Other medications are not specified, so it's best to discuss with the trial team.

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

Research shows that STK-012 has been tested on 47 patients as a standalone treatment. These early studies aimed to find the highest safe dose. So far, results suggest that STK-012 is generally well-tolerated.

When combined with pembrolizumab, STK-012 is still under evaluation to ensure safety. The goal is to find a dose that works effectively without causing serious side effects. Researchers aim to balance treatment effectiveness with safety.

STK-012 is also being studied with pembrolizumab, pemetrexed, and carboplatin. These drugs have been used together before, especially for certain lung cancers, and have shown an acceptable safety level.

In this early research phase, the main focus is on how well patients handle these treatments. Since this is the first phase of human studies, safety findings are still being collected and reviewed. Ongoing research aims to find a treatment plan that reduces risks while increasing potential benefits. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Most cancer treatments involve chemotherapy or immunotherapy that work by either killing rapidly dividing cells or boosting the immune system to attack cancer cells. The treatments being explored, STK-012 and pembrolizumab, are unique because STK-012 is a novel agent thought to enhance the immune response against cancer. Researchers are excited about STK-012 because it can be administered subcutaneously, potentially offering a more convenient delivery method than traditional intravenous therapies. Additionally, the combination with pembrolizumab, an established immunotherapy, could amplify the immune system's ability to target and destroy cancer cells, offering new hope for patients with advanced cancers.

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

Research has shown that the drug STK-012, one of the treatments in this trial, has potential in treating advanced solid tumors when used alone. Early results suggest it increases certain proteins that aid the immune system and promotes the growth of specific T cells, which play a crucial role in fighting cancer. In this trial, some participants will receive STK-012 combined with pembrolizumab, a current cancer medication. Researchers believe these treatments might work better together than separately. Pembrolizumab has already demonstrated benefits in effectiveness and duration in previous studies. Additionally, this trial is examining the combination of STK-012, pembrolizumab, pemetrexed, and carboplatin for its potential effectiveness in certain types of cancer, particularly in patients whose tumors are PD-L1 negative, indicating they might respond well to this treatment. ^{2 4 6 7 8}

Are You a Good Fit for This Trial?

This trial is for adults with certain advanced solid tumors who have tried standard treatments without success, can't tolerate them, or chose not to use them. They must provide a tumor tissue sample and if they have brain metastases, these should be treated and stable. People can't join if they've had recent cancer therapy or radiotherapy.

Inclusion Criteria

My cancer has worsened after standard treatment, or I couldn't tolerate or chose not to undergo standard treatment.

I can provide a sample of my tumor, or I agree to a new biopsy if needed.

I have had treatment for brain metastases and do not have symptoms.

Exclusion Criteria

I have received IL-2 or IL-15 therapy before.

I have recently had radiotherapy for cancer outside of the brain.

I haven't taken any cancer drugs or small molecule inhibitors recently.

Pembrolizumab (KEYTRUDA) was approved by the FDA for treating advanced melanoma, showing an overall response rate of 24% in a trial of 89 patients, with 86% of responses lasting at least 6 months.

While there are potential immune-mediated side effects, the benefits of prolonged tumor response durations were deemed to outweigh these risks, marking an improvement over existing treatments.
