What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new method to treat lung cancer using photodynamic therapy. This approach involves injecting Porfimer Sodium, a drug that makes cancer cells sensitive to light, followed by laser application to shrink the tumor. The trial aims to assess the treatment's effectiveness and potential side effects for lung cancer that has spread nearby. Individuals with lung cancer causing an airway blockage of more than 25% who require bronchoscopic intervention may be suitable candidates for this trial. As a Phase 1, Phase 2 trial, the research focuses on understanding the treatment's effects in people and measuring its effectiveness in an initial, smaller group.

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 study team or your doctor.

What prior data suggests that this photodynamic therapy is safe for treating lung cancer?

Research has shown that photodynamic therapy with porfimer sodium has been safely used for some time. Porfimer sodium activates when exposed to a special light, aiding in tumor reduction. It is approved for treating lung cancer to clear blocked airways and relieve symptoms.

Studies have identified some side effects of this treatment, with common ones including swelling and mild pain in the treated area. Patients should be aware that if the tumor is in a challenging location, swelling may risk airway blockage.

Research on ultrasound-guided interstitial photodynamic therapy (using sound waves to guide treatment) also indicates safety. This method has been tested in individuals with lung cancer and has shown promise without major safety concerns.

Overall, both treatments are generally well-tolerated, but they come with some risks to consider. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about this treatment for lung cancer because it combines photodynamic therapy (PDT) with a unique delivery method. Unlike standard treatments like surgery, chemotherapy, or radiation, this approach uses porfimer sodium, a photosensitizing agent, activated by light delivered directly to the tumor via ultrasound-guided transbronchial needle. This targeted method means the treatment can potentially be more precise, minimizing damage to surrounding healthy tissue. Additionally, it could offer a new option for patients who may not be candidates for traditional therapies, providing hope for more effective and personalized cancer care.

What evidence suggests that this photodynamic therapy is effective for lung cancer?

Research has shown that photodynamic therapy using porfimer sodium effectively treats lung cancer. In this trial, participants will receive porfimer sodium followed by endobronchial ultrasound-guided interstitial photodynamic therapy (I-PDT). Studies have found that all patients with non-small cell lung cancer (NSCLC) had a complete response to this treatment. This therapy involves injecting a light-sensitive drug and activating it with a laser to shrink tumors. The FDA has approved photodynamic therapy for treating lung cancer in the airways. Endobronchial ultrasound, which allows doctors to see inside the airways, guides the treatment accurately, potentially making it safer and more effective. This method may help control tumor bleeding and improve symptoms. ^{3 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for adults with lung cancer that's spread to nearby areas, who can undergo bronchoscopy under anesthesia. They must have a certain level of platelets in their blood, be able to use birth control if needed, and not be pregnant. People with recent radiotherapy, allergies to porphyrin, unstable health conditions or those unable to follow the study plan cannot join.

Inclusion Criteria

A specialist has confirmed that my airway can be treated with a procedure.

Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure

I am willing to undergo a specific low-dose radiation treatment as advised by my radiation oncologist.

Exclusion Criteria

My cancer has spread into the esophagus, confirmed by a special camera test.

Any condition which in the Investigator's opinion deems the participant an unsuitable candidate to receive I-PDT or PDT

I am not cleared for advanced bronchoscopy under general anesthesia.

What Are the Treatments Tested in This Trial?

Interventions

• Porfimer Sodium
• Ultrasound-Guided Transbronchial Needle-Delivered Interstitial Photodynamic Therapy

Trial Overview

The trial tests a treatment called interstitial photodynamic therapy (I-PDT) using Porfimer sodium on patients with advanced lung cancer. It involves injecting this drug and activating it with laser light inside the airways to shrink tumors.

How Is the Trial Designed?

Group I: Treatment (porfimer sodium, EBUS, and photodynamic therapy) Experimental Treatment 2 Interventions

Treatment (porfimer sodium, EBUS, and photodynamic therapy) Patients receive 2 mg/kg porfimer sodium IV over 3-5 minutes 48 +/- 4 hours prior to the delivery of I-PDT. Patients then undergo EBUS-TBN guided I-PDT over few hours.
