Vizimpro (dacomitinib) is a kinase inhibitor indicated for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletion or exon 21 L858R substitution mutations as detected by an FDA-approved test. Common side effects of Vizimpro include:

  • diarrhea,
  • rash,
  • fungal infection of the fingernails or toenails,
  • swelling and sores inside the mouth,
  • decreased appetite,
  • dry skin,
  • weight loss,
  • hair loss,
  • cough, and
  • itching

The recommended dosage of Vizimpro is 45 mg orally once daily with or without food. Vizimpro may interact with proton pump inhibitors (PPIs) and CYP2D6 substrates (antidepressants, antipsychotics, narcotics, beta-blockers, antiarrhythmics, stimulants, and others). Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant or plan to become pregnant before using Vizimpro; it can harm a fetus. Females of reproductive potential are advised to use effective contraception during treatment with Vizimpro and for at least 17 days after the final dose. It is unknown if Vizimpro passes into breast milk. Because of the potential for serious adverse reactions in breastfed infants, breastfeeding is not recommended during treatment with Vizimpro and for at least 17 days after the last dose.

Our Vizimpro (dacomitinib) Tablets, for Oral Use Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

SIDE EFFECTS

The following adverse drug reactions are described elsewhere in the labeling:

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data in the Warnings and Precautions section reflect exposure to VIZIMPRO in 394 patients with first-line or previously treated NSCLC with EGFR exon 19 deletion or exon 21 L858R substitution mutations who received VIZIMPRO at the recommended dose of 45 mg once daily in 4 randomized, active-controlled trials [ARCHER 1050 (N=227), Study A7471009 (N=38), Study A7471011 (N=83), and Study A7471028 (N=16)] and one single-arm trial [Study A7471017 (N=30)]. The median duration of exposure to VIZIMPRO was 10.8 months (range 0.07-68) [see WARNINGS AND PRECAUTIONS].

The data described below reflect exposure to VIZIMPRO in 227 patients with EGFR mutation-positive, metastatic NSCLC enrolled in a randomized, active-controlled trial (ARCHER 1050); 224 patients received gefitinib 250 mg orally once daily in the active control arm [see Clinical Studies]. Patients were excluded if they had a history of ILD, interstitial pneumonitis, or brain metastases. The median duration of exposure to VIZIMPRO was 15 months (range 0.07-37).

The most common (>20%) adverse reactions in patients treated with VIZIMPRO were diarrhea (87%), rash (69%), paronychia (64%), stomatitis (45%), decreased appetite (31%), dry skin (30%), decreased weight (26%), alopecia (23%), cough (21%), and pruritus (21%).

Serious adverse reactions occurred in 27% of patients treated with VIZIMPRO. The most common (≥1%) serious adverse reactions were diarrhea (2.2%) and interstitial lung disease (1.3%). Dose interruptions occurred in 57% of patients treated with VIZIMPRO. The most frequent (>5%) adverse reactions leading to dose interruptions were rash (23%), paronychia (13%), and diarrhea (10%). Dose reductions occurred in 66% of patients treated with VIZIMPRO. The most frequent (>5%) adverse reactions leading to dose reductions were rash (29%), paronychia (17%), and diarrhea (8%).

Adverse reactions leading to permanent discontinuation of VIZIMPRO occurred in 18% of patients. The most common (>0.5%) adverse reactions leading to permanent discontinuation of VIZIMPRO were: rash (2.6%), interstitial lung disease (1.8%), stomatitis (0.9%), and diarrhea (0.9%).

Tables 3 and 4 summarize the most common adverse reactions and laboratory abnormalities, respectively, in ARCHER 1050. ARCHER 1050 was not designed to demonstrate a statistically significant difference in adverse reaction rates for VIZIMPRO or for gefitinib for any adverse reaction or laboratory value listed in Table 3 or 4.
