What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to evaluate the effectiveness of selpercatinib (RETEVMO) for individuals with advanced or recurring non-small cell lung cancer that has a specific gene change called RET fusion-positive. The treatment may inhibit tumor growth by blocking certain enzymes essential for cancer cells. Individuals diagnosed with RET fusion-positive non-small cell lung cancer who have previously undergone chemotherapy may be suitable candidates. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot take certain medications like strong inhibitors or inducers of CYP3A4 or proton pump inhibitors during the trial. It's best to discuss your current medications with the trial team to see if any adjustments are needed.

Is there any evidence suggesting that selpercatinib is likely to be safe for humans?

Research has shown that selpercatinib was tested for safety in patients with RET fusion-positive non-small cell lung cancer. In earlier studies, common side effects included dry mouth, diarrhea, and high blood pressure, affecting about 25% or more of patients. Serious side effects occurred in 44% of patients, though the sources do not provide details.

Selpercatinib is already FDA-approved for treating other types of cancer, indicating that its safety has been studied. However, individual experiences may vary, so discussing any concerns with a doctor is essential. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for non-small cell lung cancer, which often include chemotherapy, radiation, and targeted therapies like EGFR or ALK inhibitors, selpercatinib targets a specific genetic mutation known as RET. This precision approach means selpercatinib can directly interfere with the cancer’s growth mechanisms if the RET mutation is present. Researchers are excited because it offers a more personalized treatment option that could lead to better outcomes for patients with this genetic profile, potentially with fewer side effects than traditional treatments.

What evidence suggests that selpercatinib might be an effective treatment for non-small cell lung cancer?

Research has shown that selpercatinib effectively treats RET fusion-positive non-small cell lung cancer (NSCLC). In one study, patients taking selpercatinib lived without their cancer worsening for an average of 24.8 months, compared to 11.2 months for those not on the treatment. Additionally, 84% of patients responded well to the treatment. Another study found that selpercatinib continues to work over time and remains effective even when the cancer has spread to the brain, with mostly mild side effects. These findings suggest that selpercatinib could be a promising option for people with this type of lung cancer. ^{1 2 6 7 8}

Published Research Related to This Trial

Selpercatinib showed a high objective response rate (ORR) of 84% in treatment-naive patients and 61% in those previously treated with platinum-based chemotherapy, indicating its efficacy in RET fusion-positive non-small-cell lung cancer (NSCLC).

The treatment demonstrated durable responses, with a median duration of response (DoR) of 20.2 months for treatment-naive patients and 28.6 months for those pretreated, along with a significant intracranial ORR of 85% in patients with CNS metastasis.

Selpercatinib is an effective oral treatment for advanced RET fusion-positive non-small cell lung cancer (NSCLC), showing strong and lasting responses in both previously treated and treatment-naïve patients during a pivotal phase 1/2 clinical trial.

The drug has a manageable safety profile, with most adverse events being manageable through dose adjustments, and only a small number of patients discontinuing treatment due to side effects, which primarily included hypertension and elevated liver enzymes.

In a study of 329 patients with RET fusion-positive NSCLC, 7% experienced hypersensitivity reactions to selpercatinib, with a higher incidence in patients previously treated with immune checkpoint inhibitors (ICIs) (77% of cases).

Hypersensitivity reactions to selpercatinib were manageable with supportive care, and many patients were able to continue treatment after dose modifications, indicating that while there is a risk, it is generally low and reversible.
