Harmonic Clinical Trial

The Harmonic™ clinical trial is enrolling participants in a Phase 2 multi-center study to evaluate an investigational new drug called LP-300. This trial is for never smoker patients with relapsed advanced primary adenocarcinoma of the lung, which is a type of non-small cell lung cancer (NSCLC).

Former smokers with NSCLC that has similar genetic makeup as never smokers may be eligible for the study. Please discuss this study with your healthcare provider to determine whether you may be eligible.

What Does It Mean to Be a Never Smoker With NSCLC?

The US Centers for Disease Control (CDC) defines a never smoker as an adult who has never smoked or has smoked less than 100 cigarettes in his or her lifetime. A never smoker can develop NSCLC, which is clinically and genetically different from NSCLC in smokers. Harmonic™ is a clinical trial that is evaluating the overall and progression-free survival of never smoker patients with relapsed advanced NSCLC after treatment with the investigational new drug LP-300 in combination with chemotherapy.

Former smokers with NSCLC that has similar genetic makeup as never smokers may be eligible for the study. Please discuss this study with your healthcare provider to determine whether you may be eligible.

About NSCLC and the Investigational New Drug, LP-300

Harmonic™ trial’s investigational new drug, LP-300, works together with chemotherapy by interacting in the tyrosine kinase gene pathways, interrupting their activity to slow or prevent tumor growth and spread. LP-300 has been approved by the US Food and Drug Administration for Investigational use in this clinical trial.

NSCLC presents differently in never smokers compared to smokers and is likely due to a higher percentage of genetic mutations in a family of cancer promoting genes called Tyrosine Kinases (TK). Changes in TK genes, such as EGFR, ALK, ROS and MET, can contribute to the development of healthy cells into cancer cells, leading to tumor formation and growth.

You may be eligible for the trial if you are a never smoker and your NSCLC has worsened despite taking a targeted therapy known as a tyrosine kinase inhibitor (TKI). You can find out more information on eligibility requirements here.

What Does Taking Part in the Harmonic™ Trial Involve?

Screening Period

You will be evaluated to see if you are eligible to participate in this study. A member of the research team will discuss the study details with you using what is called an informed consent form. After you have agreed to participate and signed the informed consent form, the research team will collect your medical history and do all the laboratory tests, tumor imaging scans, and exams that are necessary to determine your eligibility for study participation. The evaluation can take up to 28 days.

Dosing Period

If you are eligible to participate, you will be assigned to receive either LP-300 with carboplatin and pemetrexed chemotherapy or carboplatin and pemetrexed chemotherapy alone. The drugs will be given on Day 1 of a 21-day cycle (A period of treatment followed by a period of rest (no treatment) that is repeated on a regular schedule) for a total of 6 cycles. After you are finished with the 6 cycles, you will have the option to continue pemetrexed maintenance chemotherapy until your cancer progresses, you experience unacceptable side effects, or you and/or your physician decide that you should discontinue it.

Follow-up Period

Once you stop taking the investigational new drug, you will return to your healthcare provider 14 days after the last dose to see how you are doing. You will then have follow-up visits every 9 weeks for the first year and every 3 months thereafter. During these follow-up visits, the research team will monitor your cancer and update any changes to your medical history.

Frequently Asked Questions

I have tried smoking once, but never continued. Am I still a never smoker?

Expand the FAQ sectionClose the FAQ section

Yes, you are a never smoker if you have smoked less than 100 cigarettes in your lifetime.

Will I receive placebo or no treatment if I am not assigned to the LP-300 group?

Expand the FAQ sectionClose the FAQ section

No, you will still receive standard of care treatment. Although you won't receive the investigational new drug, you will be provided with the standard of care chemotherapies pemetrexed and carboplatin.

What are the benefits of joining a clinical trial?

Expand the FAQ sectionClose the FAQ section

You have the chance to contribute to medical research and help others with your condition. You may also receive more monitoring and check-ups from your health care providers.

What is a clinical trial?

Expand the FAQ sectionClose the FAQ section

A clinical trial is a type of research study that looks at the safety and effectiveness of an investigational drug or treatment intervention.

What is an investigational drug?

Expand the FAQ sectionClose the FAQ section

An investigational drug is a drug that has not been approved by the U.S. Food and Drug Administration (FDA) for use in the general public. However, it can be used in a clinical trial to learn more about the drug's safety and effectiveness.

What are the chances that I will receive the LP-300 investigational drug?

Expand the FAQ sectionClose the FAQ section

You will have a 2 in 3 chance of receiving the LP-300 drug. However, if you are not assigned to receive LP-300, you will still receive pemetrexed and carboplatin as standard of care chemotherapies.

How long will this clinical trial last?

Expand the FAQ sectionClose the FAQ section

If you are eligible to participate in the Harmonic™ Trial, you will receive study treatment every 3 weeks for a total of 6 cycles. Then, depending on how you are responding, you may continue on pemetrexed maintenance therapy every 3 weeks until your cancer progresses, you have side effects you cannot tolerate, or you or your physician think you should discontinue it.
