What is the purpose of this trial?

This trial tests a new cancer treatment called bemarituzumab, combined with other anti-cancer drugs to assess its safety and effectiveness. It targets squamous cell lung cancer that cannot be surgically removed or has metastasized. The trial seeks patients whose tumors exhibit FGFR2b overexpression and who have not succeeded with previous treatments. Some participants will receive bemarituzumab alone, while others will receive it with chemotherapy drugs such as carboplatin, docetaxel, nab-paclitaxel, or paclitaxel. The research aims to determine the optimal dose for future studies. As a Phase 1 trial, it focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial information does not specify if 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 the safety of bemarituzumab is actively studied in various combinations for treating squamous cell lung cancer. In studies combining bemarituzumab with docetaxel, early results suggest the treatment is generally well-tolerated, with participants experiencing side effects similar to those expected from these drugs individually.

When used alone, bemarituzumab is generally safe, according to research, with ongoing studies focusing on its effects in patients with solid tumors.

For the combination of bemarituzumab with pembrolizumab, carboplatin, and paclitaxel or nab-paclitaxel, studies have found this mix to be safe and effective for lung cancer patients. Previous findings show the combination is well-tolerated, with side effects similar to those of the individual treatments.

Overall, these studies have found the treatments to be generally safe, but like any medical treatment, side effects can occur. Participants receive close monitoring to ensure their safety throughout the trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about bemarituzumab for squamous cell lung cancer because it targets FGFR2b, a protein often overexpressed in these cancer cells, which most current treatments don't address. Most treatments rely on traditional chemotherapy or immunotherapy, but bemarituzumab offers a novel approach by specifically inhibiting this growth factor receptor, potentially leading to more effective and targeted cancer cell destruction. Additionally, this treatment is being tested both alone and in combination with other drugs like docetaxel and pembrolizumab, which might enhance its effectiveness and offer more comprehensive treatment options for patients.

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

Research shows that the drug bemarituzumab, when combined with docetaxel, may help treat squamous cell non-small cell lung cancer (sqNSCLC). In this trial, participants will receive bemarituzumab with docetaxel to assess its effectiveness. Early results indicate that bemarituzumab alone, tested in a separate arm of this trial, is safe and might help fight tumors. Another arm of this trial will test bemarituzumab combined with other drugs such as pembrolizumab, carboplatin, and either paclitaxel or nab-paclitaxel. Research shows that these combinations may extend the lives of patients with similar lung cancers. These treatments appear to work well together, offering hope for better outcomes. ^{1 5 6 7 8}

Are You a Good Fit for This Trial?

This trial is for adults with a specific lung cancer type (SqNSCLC) that can't be removed by surgery or has spread, and shows high levels of FGFR2b protein. Participants must have tried at least one systemic therapy before, unless they're in Part 4 where no prior treatment for advanced disease is allowed. They need good organ function and an ECOG status of 0 or 1, meaning they are fully active or restricted in physically strenuous activity but can do light work.

Inclusion Criteria

I have a tumor tissue sample from the last 5 years or am willing to provide one.

My organs are working well.

I haven't had systemic therapy for my advanced or metastatic disease yet.

Exclusion Criteria

My cancer got worse after treatment with docetaxel.

I have had docetaxel for advanced cancer but not as an early treatment that didn't progress quickly.

I have serious heart issues, including recent heart attacks or uncontrolled blood pressure.

Published Research Related to This Trial

In a phase III trial involving 1,052 patients with advanced non-small-cell lung cancer, nab-paclitaxel plus carboplatin showed a significantly higher overall response rate (33%) compared to solvent-based paclitaxel plus carboplatin (25%), indicating greater efficacy in treatment.

Nab-paclitaxel was associated with fewer severe side effects, such as neuropathy and neutropenia, compared to solvent-based paclitaxel, suggesting it may be a safer option for patients.

In a phase II trial involving 15 patients with resectable non-small cell lung cancer (NSCLC), neoadjuvant treatment with pembrolizumab showed a major pathologic response in 27% of patients, indicating promising antitumor activity before surgery.

The treatment was found to be feasible and safe, with only 33% of patients experiencing moderate adverse events, and no postoperative mortality, suggesting that pembrolizumab does not compromise surgical outcomes.

In a real-life study of 121 patients with advanced non-squamous non-small cell lung cancer, the combination of pembrolizumab and chemotherapy resulted in a median progression-free survival of 9 months and overall survival of 20.6 months, demonstrating its efficacy as a first-line treatment.

The treatment was generally well-tolerated, with manageable side effects; however, 17.5% of patients experienced grade 3-4 adverse events, and there were two treatment-related deaths, indicating the need for careful monitoring during therapy.

In a small study of 6 women with heavily pretreated HER2-negative metastatic breast cancer, the combination of nab-paclitaxel (nab-P) and bevacizumab (B), with or without gemcitabine (G), showed promising safety and preliminary efficacy, with only one patient experiencing significant toxicity.

Out of the 6 patients, 2 achieved partial responses and 4 had stable disease, indicating that this combination therapy may be effective, warranting further investigation in a formal phase II trial.

A phase 3 study (J-AXEL) is underway to compare the efficacy and safety of nab-paclitaxel to docetaxel in patients with previously treated advanced non-small-cell lung cancer (NSCLC), involving randomization of patients to receive either treatment until disease progression or unacceptable toxicity.

The primary goal of the study is to demonstrate that nab-paclitaxel is noninferior to docetaxel in terms of overall survival, which could establish nab-paclitaxel as a new treatment option for these patients.

In a Phase 2 study involving 29 patients with advanced non-small cell lung cancer (NSCLC) who had previously failed PD-(L)1 inhibitor treatment, nab-paclitaxel demonstrated a promising objective response rate (ORR) of 55.2%, indicating its efficacy as a subsequent treatment option.

The treatment was associated with manageable safety profiles, with significant toxicities including leukopenia (27.6%) and neutropenia (31.0%), suggesting that while nab-paclitaxel is effective, monitoring for these side effects is important.

The combination therapy was well tolerated with a lower incidence of severe neutropenia compared to traditional solvent-based paclitaxel, showing promising activity against various solid tumors, including lung and breast cancers.
