What is the purpose of this trial?

This trial aims to determine if the new drug, XB010, is safe and effective alone or with pembrolizumab (an immunotherapy drug) for treating advanced cancers. It targets solid tumors that cannot be surgically removed or have metastasized. The trial includes different groups to assess the drug's effectiveness for specific cancers, such as lung, breast, and head and neck cancers. It suits individuals with confirmed advanced or recurrent solid tumors who have no other treatment options. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new drug.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

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

Research shows that pembrolizumab is generally well-tolerated. The FDA has already approved it for other types of cancer, indicating its safety is well understood. Common side effects include fatigue, skin rash, and diarrhea.

For XB010, less information is available because it is a new drug. Early lab research showed it could effectively fight tumors. However, since this is the first human trial for XB010, its safety is still under evaluation. Possible side effects might include nausea or fatigue, but more details will emerge as more participants join the trials.

The combination of XB010 with pembrolizumab remains under study, and researchers are gathering more safety information. Participants will be closely monitored to identify any new side effects from this combination. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about XB010, both as a single agent and in combination with Pembrolizumab, because it targets cancer cells in a unique way. Unlike traditional treatments that might focus solely on blocking cancer cell growth, XB010 is being explored for its ability to enhance the immune system's natural ability to fight cancer. This new mechanism of action could potentially improve outcomes for patients with challenging cancers like non-small cell lung cancer and triple-negative breast cancer. By combining XB010 with Pembrolizumab, which is already known to boost the immune response against cancer, there is hope for a more effective treatment strategy.

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

Research has shown that XB010, a new treatment, holds promise in fighting tumors based on early studies. It successfully stopped cancer cell growth in lab tests and reduced tumor size in animals. In this trial, some participants will receive XB010 as a single agent to test its effects on different cancers, such as certain types of lung and breast cancer.

Other participants will receive a combination of XB010 and pembrolizumab. Early results suggest that this combination might enhance the immune system's ability to fight cancer. Pembrolizumab is already a well-known treatment that helps the body defend against tumors. Together, these treatments could offer a new option for people with advanced cancers that haven't responded to other treatments. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• Pembrolizumab
• XB010

Trial Overview The study investigates XB010 alone and combined with pembrolizumab to assess safety, tolerability, how the body processes it (PK), immune response (immunogenicity), and initial effectiveness against tumors in subjects whose cancer has spread.

How Is the Trial Designed?

Group I: XB010 Single-Agent Dose Expansion Cohorts Experimental Treatment 1 Intervention

XB010 will be administered at the recommended dose for expansion (RDE) every 3 weeks in the following tumor-specific cohorts: non-small cell lung cancer (NSCLC), hormone-receptor-positive breast cancer (HR+BC), head and neck squamous cell cancer (HNSCC), esophageal squamous cell cancer (ESCC), endometrial cancer (EC) and triple-negative breast cancer (TNBC)

Group II: XB010 Single-Agent Dose Escalation Cohorts Experimental Treatment 1 Intervention

XB010 will be administered at escalating dose levels every 3 weeks in cohorts of 3-12 subjects

Group III: XB010 + Pembrolizumab Dose Escalation Cohorts Experimental Treatment 2 Interventions

XB010+Pembrolizumab will be administered at escalating dose levels every 3 weeks in cohorts of 3-12 subjects

Published Research Related to This Trial

Pembrolizumab (Keytruda) was approved by the FDA for treating metastatic non-small cell lung cancer (mNSCLC) in patients with tumors expressing PD-L1, showing significant improvements in overall survival (OS) and progression-free survival (PFS) in two major clinical trials with thousands of participants.

In the KEYNOTE-024 trial, pembrolizumab demonstrated a 40% reduction in the risk of death compared to chemotherapy, while in the KEYNOTE-010 trial, it also showed a significant survival advantage over chemotherapy in patients who had previously progressed on treatment.

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.
