Key Points

The effectiveness of Exkivity was determined by looking at the overall response rate (ORR) and the duration of response (DoR) to treatment.

In clinical studies, 32 of 114 patients (28%) with non-small cell lung cancer (NSCLC) had a partial response to Exkivity treatment. In these patients, the response to treatment lasted for about 17.5 months.

Close to 59% of patients who responded had a response that lasted at least 6 months. Median overall survival was 24 months (2 years).

Exkivity study results

In Sept., 2021, the FDA granted accelerated approval to Exkivity (mobocertinib) based on a clinical research study known as Study 101. This study included 114 patients with non-small cell lung cancer (NSCLC) that had spread to other parts of the body and could not be removed by surgery. These patients had EGFR exon 20 insertion mutations in their lung cancer, as determined by a special test.

Patients were on or had previously received a chemotherapy treatment that contained platinum, but their disease had worsened. In the study, the participants received a 160 mg oral dose of Exkivity once daily until their lung cancer worsened or they had side effects they could not tolerate.

The effectiveness of Exkivity was determined by looking at the overall response rate (ORR) and the duration of response (DoR). The ORR looks at how many people using Exkivity saw a tumor response like shrinkage. The DoR measures how long the response lasted.

Overall, about 28% of the people (32/114) had a partial response to Exkivity treatment and the response lasted for about 17.5 months. Close to 59% of patients who responded (19/32) had a response that lasted at least 6 months. The median overall survival was 24 months (2 years). Median means that half the people lived longer than 24 months, and the other half lived less than 24 months.

Exkivity common side effects

The most common side effects (>20%) reported in Study 101 for Exkivity were:

Diarrhea

Rash

Mouth sores

Vomiting

Decreased appetite

Infection of skin around nails

Nausea

Muscle or bone pain

Dry skin

Feeling Tired

Exkivity labeling carries a Boxed Warning for QTc prolongation and Torsades de Pointes (types of dangerous heart rhythms), warnings for certain types of lung or heart toxicity, and diarrhea.
