Abstract

Aim: Real-world adverse event (AE) data are limited for first-line (1L) treatments in advanced non-small-cell lung cancer (NSCLC). Methods: Using Flatiron Health Spotlight data, information for a pre-specified list of AEs was abstracted and described among patients with advanced NSCLC receiving 1L nivolumab + ipilimumab (NIVO + IPI), NIVO + IPI + chemotherapy and other approved immuno-oncology (IO) therapy + chemotherapy combination therapies. Results: Fatigue, pain, dyspnea, weight loss, decreased appetite, diarrhea, nausea/vomiting, cough, constipation and rash were the most common AEs. Rates of AEs were generally numerically similar across the three cohorts. The majority of patients received treatment for AEs and approximately one fourth of the patients had hospitalization due to their AEs. Conclusion: The real-world safety experiences of patients treated with 1L NIVO + IPI-based regimens were in general similar to those treated with other approved IO + chemotherapy combination therapies.

Plain language summary

Immuno-oncology (IO) therapies boost the immune system to fight cancer cells and have been approved to treat non-small-cell lung cancer (NSCLC). The IO combination of nivolumab + ipilimumab (NIVO + IPI) is approved to treat NSCLC that has spread to other parts of the body or come back and at least 1% of the tumor cells express a protein called PD-L1; NIVO + IPI is also approved in combination with a short course chemotherapy, independent of tumor PD-L1 expression. While NIVO + IPI-based regimens are generally safe, some patients experienced side effects during the clinical trial. However, there is limited information on the side effects of these treatments in a real-world setting. This study analyzed data on side effects from a de-identified database of patients with advanced NSCLC who were treated with NIVO + IPI, NIVO + IPI + chemotherapy, or other approved IO + chemotherapy combinations based on information obtained from physicians’ notes in clinical practice settings. The most common side effects among patients in all groups were tiredness, pain, shortness of breath, weight loss, decreased appetite, diarrhea, nausea/vomiting, cough, constipation and rash. The rates at which the side effects occurred were numerically similar regardless of the specific treatment that patients received. Approximately one-quarter of patients in each treatment group were hospitalized because of a side effect. These results show that in a real-world setting, NIVO + IPI-based regimens have similar safety to other IO + chemotherapy combinations when used as a first treatment for NSCLC that has spread or come back.

The introduction of immuno-oncology (IO) agents has expanded the available treatment options for advanced or metastatic non-small-cell lung cancer (NSCLC) [Citation1]. These therapies have different antitumor mechanisms, including targeting immune checkpoint pathway components such as PD-1 inhibitors (nivolumab [Citation2], pembrolizumab [Citation3] and cemiplimab [Citation4]), PD-L1 inhibitors (atezolizumab [Citation5] and durvalumab [Citation6]), CTLA-4 blockers (ipilimumab [Citation7] and tremelimumab [Citation8]), as well as suppressing tumor angiogenesis (bevacizumab [Citation9]). Clinical trials have established the efficacy and safety of these IO therapies compared with chemotherapy [Citation10,Citation11].

In May 2020, the combination of nivolumab + ipilimumab (NIVO + IPI) was approved for the first-line (1L) treatment of adult patients with metastatic NSCLC whose tumors express PD-L1 (≥1%) without EGFR or ALK genomic tumor aberrations and the combination of NIVO + IPI with 2 cycles of platinum-doublet chemotherapy was approved for the 1L treatment of adult patients with metastatic NSCLC with no EGFR or ALK genomic tumor aberrations regardless of tumor PD-L1 expression [Citation12–14]. The approvals were based on results from the CheckMate 227 [Citation15–17] and CheckMate 9LA [Citation18–20] trials, which showed superior overall survival with NIVO + IPI (+2 cycles of platinum doublet chemotherapy in CheckMate 9LA) versus chemotherapy alone. With their complementary mechanisms of action, PD-1/CTLA-four inhibitor combinations have the potential for synergistic antitumor activity [Citation21,Citation22]. While the NIVO + IPI regimens (with or without chemotherapy) had manageable safety profiles in these pivotal trials, adverse events (AEs) including fatigue, diarrhea, rash, pruritus, nausea and musculoskeletal pain were reported. As toxicities with IO combination therapies may differ from those observed with IO monotherapy [Citation23] or have additive effects [Citation24], AEs related to NIVO + IPI (with or without chemotherapy) as well as other approved IO + chemotherapy combination therapies warrant examination.

The effectiveness of some IO therapies as 1L treatment for advanced NSCLC has been described in real-world patient populations [Citation25–27], but safety data are limited as collecting comprehensive safety data in the real-world setting has always presented a significant challenge. To address this gap, AE information was curated from physician notes in the Flatiron Health Database for patients with advanced NSCLC who received 1L IO combination therapies categorized by three regimens: NIVO + IPI (Cohort 1), NIVO + IPI + chemotherapy (Cohort 2) and other approved IO + chemotherapy combination therapies (Cohort 3). This study aims to describe the real-world safety experiences of patients with advanced NSCLC when being treated with these regimens, offering insights to enhance patient care.

Methods

Data source & study design

This retrospective, observational study analyzed data from the Flatiron Health database (the October 2021 data cut), which contains structured data derived from electronic health records and unstructured data abstracted from physicians’ notes and other documents. The database includes various information such as demographics, diagnoses, disease stage and histologic subtype, laboratory results, visits and treatments. To extract safety outcomes for the study population, the Deep Spotlight model [Citation28] was utilized. As the data were de-identified, institutional review board approval was not required for this study.

Study population

Patients were eligible for inclusion if they were recorded in the advanced NSCLC Core Registry (i.e., Stage IIIB, IIIC, IVA, IVB NSCLC, or non-metastatic NSCLC that subsequently developed recurrent or progressive disease) on or after 1 January 2011 and received one of the following 1L therapies before 30 April 2021 (i.e., 6 months before the data cut-off date): NIVO + IPI (Cohort 1); NIVO + IPI + chemotherapy (Cohort 2); or other approved IO (excluding Nivo) + chemotherapy combinations (Cohort 3). Patients were excluded if they: lacked relevant unstructured data in the Flatiron Health database for review by the abstraction team; had unknown histology, a positive EGFR or ALK mutation test result at any time before the start of 1L therapy, or a gap greater than 90 days between advanced NSCLC diagnosis and the first structured activity after the diagnosis. In the end, all eligible patients from Cohort 1 and Cohort 2, and a randomly selected sample of patients from Cohort 3 were included for the abstraction of safety data.

Outcomes

Data on the following AEs that occurred during 1L therapy were abstracted: fatigue, pain, dyspnea, weight loss, decreased appetite, nausea/vomiting, cough, diarrhea, constipation, rash, peripheral edema, dizziness, pruritus, headache, insomnia, lung infection, peripheral neuropathy, hemoptysis, urinary tract infection, hypothyroidism, colitis, pneumonitis, syncope, pulmonary embolism, atrial fibrillation, hyperthyroidism and febrile neutropenia.

Although information on AE grades was not available, the available data on the incidents related to the AEs, including strategies used for their management, were described. Therapy discontinuation was defined as discontinuation (without restarting) of any component of the reference 1L regimen resulting from the AE. Therapy dose or schedule change was defined as modification of the dose or treatment schedule, respectively, of any component of the reference regimen resulting from the AE. Therapy hold was defined as interruption or delay of the reference regimen due to the AE. Hospitalization was defined as inpatient admission as a result of the AE. Treatment for the AE was defined as any treatment (including non-pharmacologic) that was recommended, prescribed, or administered by the clinician to treat the AE. Death resulting from the AE was also abstracted.

Analysis

Baseline patient demographics and clinical characteristics during the 6 months before and 1 month after the index date were summarized for each cohort using mean ± standard deviation (SD), median, interquartile range (IQR) for continuous variables or number (percentage) for categorical variables. The rates of AEs that occurred during 1L therapy were described for each cohort as number and proportion of patients with AEs. The exposure-adjusted AE rates were reported in cases per patient month, which were calculated as the number of patients who experienced AEs divided by the total treatment exposure time (in months). The total treatment exposure time was defined as the duration from the initiation of 1L therapy to either the initial occurrence of the AE for patients who experienced it, or the end of 1L therapy for those who did not experience the AE. Additionally, the impact of AEs was assessed for each cohort as number and percentage of patients who experienced AE-related incidents.

Results

The study population consisted of 262 patients, with 137 patients in Cohort 1 (NIVO + IPI), 46 patients in Cohort 2 (NIVO + IPI + chemotherapy), and 79 patients in Cohort 3 (other IO + chemotherapy combination therapy). The 137 patients in Cohort 1 and the 46 patients in Cohort 2 represent the entirety of the eligible patients treated with NIVO + IPI without and with chemotherapy within the Flatiron database at the time of the study.

Discussion

This study described the real-world AE profiles of 1L IO combination therapy in patients with advanced NSCLC in the USA. While some small variations in patients’ safety experiences were observed, the rates of AEs were generally numerically similar across different IO combination regimens. In addition, a majority of patients in each cohort received treatment for AEs, and approximately one-quarter of patients required hospitalization due to AEs. Overall, the safety experiences of patients with advanced NSCLC treated with NIVO + IPI-based combination therapies appear similar to those treated with other IO + chemotherapy combination regimens.

The most common AEs across the three cohorts included fatigue, pain, dyspnea, weight loss, decreased appetite, diarrhea, nausea/vomiting, cough, constipation and rash. Among these, fatigue and pain affected over 60% of patients in all three cohorts, consistent with previous studies that have reported these AEs as commonly associated with cancer treatment [Citation29]. The rates of nausea/vomiting were numerically lower in Cohort 1 (NIVO + IPI; 35.8%) than in Cohort 2 (NIVO + IPI + chemotherapy; 58.7%) and Cohort 3 (other IO + chemotherapy; 51.9%). This difference is likely due to the fact that nausea and vomiting, along with other AEs such as weight or appetite loss and peripheral neuropathy, are frequently linked to chemotherapy [Citation30,Citation31].

The majority of patients in all cohorts received treatment for AEs. This indicated a high level of AE management across the cohorts. The impact of AEs on therapy hold and therapy discontinuation were relatively consistent across the cohorts. However, therapy dose or schedule changes were numerically less frequently observed in Cohort 1 (NIVO + IPI; 4.4%) and Cohort 2 (NIVO + IPI + chemotherapy; 4.3%), compared with Cohort 3 (other IO + chemotherapy; 12.7%). These differences suggest that NIVO + IPI-based regimens may be associated with a lower need for modifying the treatment dose or schedule due to AEs. This could be partially attributed to the lower number of chemotherapy cycles planned in these regimens.

The rates of hospitalization related to AEs were consistent across the cohorts (25.3–26.3%). This suggests that the occurrence of serious AEs requiring hospitalization was not influenced by the specific treatment regimens. It is worth noting that hospitalization has been identified as the key cost driver in the management of grade 3/4 AEs among patients with advanced NSCLC [Citation32]. Therefore, these findings indicate that treatment with NIVO + IPI-based regimens may result in similar clinical and economic burdens related to AEs when compared with other IO + chemotherapy combination therapies.

The most frequent AEs identified in our study closely align with those reported in pivotal trials, including symptoms such as nausea, vomiting, fatigue, constipation, diarrhea, decreased appetite, rash, cough and dyspnea. However, the present study observed numerically higher rates for most of the AEs compared with those reported in clinical trials [Citation16,Citation18,Citation33–36]. This disparity may be attributed to the greater frailty of the real-world population. For example, the median age of our study population (NIVO + IPI: 72.0 years old; NIVO + IPI + chemotherapy: 70.0; other IO + chemotherapy: 69.0) was higher than the median age of patients enrolled in clinical trials (ranging from 63.0 to 65.0 years old). Moreover, patients recruited in clinical trials exhibited an ECOG performance status of 0 or 1, while a considerable proportion of patients in our study had an ECOG performance status of 2+ (NIVO + IPI: 18.2%; NIVO + IPI + chemotherapy: 17.4%; other IO + chemotherapy: 12.7%) or unknown status (NIVO + IPI: 13.9%; NIVO + IPI + chemotherapy: 10.9%; other IO + chemotherapy: 20.3%). Despite the elevated AE rates in our real-world study relative to clinical trials, the relative rates among the three cohorts remain consistent with prior research utilizing clinical trial data. For example, in an indirect treatment comparison (ITC) of 1L NIVO + IPI + 2 cycles of chemotherapy versus pembrolizumab + chemotherapy in metastatic NSCLC, no differences in the rate of any-grade AEs between treatment arms were observed, whereas rates of nausea and colitis as well as hematologic AEs (anemia, neutropenia and thrombocytopenia) were lower with NIVO + IPI + chemotherapy [Citation37]. Another ITC of clinical trials of NIVO + IPI versus other relevant comparator regimens as 1L therapy in patients with metastatic NSCLC showed no significant differences in the risks of grade ≥3 AEs (odds ratio [OR]: 0.71, 95% CI: 0.45, 1.11) or the risks of an AE resulting in treatment discontinuation (OR: 0.58, 95% CI: 0.30, 1.11) between NIVO + IPI and pembrolizumab + chemotherapy [Citation38]. Additionally, a systematic review and network meta-analysis found that NIVO + IPI, with or without chemotherapy, was similar to other IO + chemotherapy combination therapies with respect to grade 3/4 AEs [Citation39].

Limitations

Our study had several limitations that should be acknowledged. Firstly, in the present study, the evaluation of AEs was limited to those occurring during 1L therapy. However, as previous research has shown that that the majority of AEs tend to manifest in the early phase of the treatment course [Citation17], the occurrence of AEs beyond discontinuation of 1L therapy was anticipated to be relatively low. Secondly, grades of AE were not available in the data. Nevertheless, certain AE-related incidents, such as AE-related hospitalization can serve as a proxy to infer the severity of AEs. Thirdly, the sample sizes for the three cohorts were limited. Although this sample represented all of the patients within the Flatiron data treated with nivolumab + ipilimumab and nivolumab + ipilimumab + chemotherapy at the time of the study, Cohort 3 only included a random sample of all eligible patients who received 1L other IO + chemotherapy combination therapies. Future studies with larger sample sizes are needed to further confirm findings from the present study. Nevertheless, results from the present study offer a unique understanding of real-world patient experiences, filling a crucial gap in the field where data scarcity prevails. Fourthly, due to the relatively small sample sizes, this study mainly focused descriptive analyses across the three cohorts without adjusting for heterogeneities or conducting statistical comparisons. Therefore, caution should be exercised when attempting to compare safety data across these cohorts. It is worth noting that patients in Cohort 1 (NIVO + IPI) were frailer, as evidenced by their older age and higher proportions of severe comorbidities, such as COPD and congestive heart failure. Lastly, our study was constrained by the fact that it only captured the incidence of a pre-specified list of AEs from the Flatiron Spotlight data. There may exist other clinically relevant AEs that were not considered in our analysis. Notably, AEs like anemia and asthenia, which affected more than 15% of the study population in pivotal trials [Citation16,Citation18,Citation33,Citation34], were not included in our current study. In addition, hepatitis, a condition with potentially life-threatening consequences, was not captured in the current study.

Conclusion

In this study population, we found that the real-world safety experiences of patients with advanced NSCLC treated with 1L NIVO + IPI-based regimens were numerically similar to those treated with other approved IO + chemotherapy combination therapies.

Summary points
  • Several immuno-oncology (IO) regimens have been approved as 1L treatments for advanced non-small-cell lung cancer (NSCLC). However, there are limited real-world safety data available for these regimens.

  • This study utilized curated Flatiron Health data (October 2021 data cut), to describe the adverse events (AEs) experienced by patients with advanced NSCLC while being treated with first-line (1L) Nivolumab + Ipilimumab (NIVO + IPI) (Cohort 1), NIVO + IPI + chemotherapy (Cohort 2), or other IO + chemotherapy combination therapies (Cohort 3).

  • Fatigue, pain, dyspnea, weight loss, decreased appetite, diarrhea, nausea/vomiting, cough, constipation and rash were the most common among patients who received 1L NIVO + IPI, NIVO + IPI + chemotherapy and other approved IO + chemotherapy combinations.

  • The proportions of patients experiencing AE-related therapy hold and therapy discontinuation were similar among patients received different 1L therapies, while 1L NIVO + IPI and NIVO + IPI + chemotherapy were less likely to require therapy dose or schedule change.

  • Results from the present study indicate that the real-world safety experiences of patients treated with 1L NIVO + IPI-based regimens are numerically similar to those treated with other approved IO + chemotherapy combination therapies.
