Study Description

Brief Summary

Small cell lung cancer (SCLC), characterized by rapid proliferation, high growth fraction and early development of metastases, is the most aggressive form of lung cancer. In 2021, an estimated 2.3 million people around the world are diagnosed with lung cancer. In France, in 2018, with 46 363 new cases and 33 117 deaths, lung cancer represented the second most common cancer and the first cause of death from cancer. Among those, SCLC represented 10,8% of all new lung diagnosis, and about two thirds presented at the extensive stage (ES-SCLC).

Since last three decades, standard treatment in ES-SCLC is based on combination chemotherapy with a platinum agent and etoposide in first-line with or without concurrent radiation therapy. Then, the second-line of treatment is topotecan, with few results in terms of response rates and survival rate. However, the emergence of immune checkpoint inhibitors targeting the programmed cell death receptor-1 (PD-1)/PD-ligand 1 (PD-L1) pathway, having an important role in immune regulation became an alternative method in the management and care of disease. Indeed, recent studies have shown an overall survival (OS) benefit for patients with ES-SCLC treated in first line with a combination of platinum-etoposide and immune checkpoint inhibitors. Atezolizumab (Tecentriq®, Roche) and durvalumab (Imfinzi®, AstraZeneca), two anti-Programmed death-ligand 1 (PD-L1) antibodies, delivered positive phase III results, respectively through the Impower-133 and CASPIAN studies, and were granted European market authorisations.

Durvalumab is approved for use in combination with etoposide and either carboplatin or cisplatin for the first-line treatment of patients with ES-SCLC. On March 10, 2020 French health authorities allowed durvalumab utilization in this setting through a national "early access program" (Autorisation Temporaire d'Utilisation "de cohorte" - ATUc), thus preceding the European market authorization (August 28, 2020). Since 2020 October 1st, durvalumab is used as a post ATU treatment. Since 2020, French AURA treatment guidelines for SCLC have referenced durvalumab in combination with chemotherapy as a first-line treatment option for patients with ES-SCLC.

Whereas the safety and efficacy of the durvalumab have been evaluated in a clinical trial, data are required to further evaluate the use of durvalumab in real-life condition and in less selected population than in clinical trials.

Condition or Disease Intervention/Treatment Phase

Detailed Description

Small cell lung cancer (SCLC), characterized by rapid proliferation, high growth fraction and early development of metastases, is the most aggressive form of lung cancer. SCLC is a relatively rare but really aggressive tumour accounting for 10-15% of all newly diagnosed lung cancer. In 2021, an estimated 2.3 million people around the world are diagnosed with lung cancer . In France, in 2018, with 46 363 new cases and 33 117 deaths, lung cancer represented the second most common cancer and the first cause of death from cancer. Among those, SCLC represented 10,8% of all new lung diagnosis, and about two thirds presented at the extensive stage (ES-SCLC).

Between 2010 and 2018, the incidence rate increased of 0,3 % per year in men. In contrast, from 1990 to 2018, the incidence increased more dramatically among women, with an increase of 5% in average per year. The 5-year survival rate for all people with all types of lung cancer is 21%. The 5-year survival rate is 17% and 24% for men and women, respectively. For SCLC, due to the rapid proliferation and high growth fraction associated to early development of metastases in the disease course (most commonly to the brain, liver, or bone), the 5-year survival rate is low at 10%. Therefore, SCLC is the most lethal lung cancer subtype. Most cases of SCLC develop in patients aged 60-80 years and the estimated overall death rate is 25,000-30,000 per year in United States. More than 90% of patients with SCLC are elderly and have heavy smoking histories.

SCLC is defined histologically as "a malignant epithelial tumour consisting of small cells with scant cytoplasm, ill-defined cell borders, finely granular nuclear chromatin, and absent or inconspicuous nucleoli", assessed by imaging techniques such as computerized tomography (CT), positron emission tomography (PET) and magnetic resonance imaging (MRI).

The Veterans' Administration Lung Study Group (VALG) staging system is usually used in the clinic routine to stage SCLC. Two categories represent SCLC, limited stage (LS) and extensive stage (ES). Limited-stage small-cell lung cancer (LS-SCLC) is defined as tumour confined to one hemithorax, with or without regional lymph-node involvement, which can be safely encompassed in a tolerable radiation field, corresponding at stage I to III of TNM system. ES-SCLC is defined as disease that cannot be safely encompassed in a tolerable radiation field, corresponding to stage IV of TNM system.

The management of SCLC is complicated by aggressiveness and substantial comorbidities, and impaired performance status. According to ESMO guidelines (2021), as well as in the French guidelines from Auvergne Rhone Alpes region, the standard management design of SCLC is described and outlined in Figure 1.

Since last three decades, standard treatment in ES-SCLC is based on combination chemotherapy with a platinum agent and etoposide in first-line with or without concurrent radiation therapy. Then, the second-line of treatment is topotecan, with few results in term of response rates and survival rate.

However, the emergence of immune checkpoint inhibitors targeting the programmed cell death receptor-1 (PD-1)/PD-ligand 1 (PD-L1) pathway, having an important role in immune regulation became an alternative method in the management and care of disease. Indeed, recent studies have shown an overall survival (OS) benefit for patients with ES-SCLC treated in first line with a combination of platinum-etoposide and immune checkpoint inhibitors. Atezolizumab (Tecentriq®, Roche) and durvalumab (Imfinzi®, AstraZeneca), two anti-Programmed death-ligand 1 (PD-L1) antibodies, delivered positive phase III results, respectively through the Impower-133 and CASPIAN studies, and were granted European market authorisations.

Durvalumab (Imfinzi®, AstraZeneca), a fully human monoclonal antibody against programmed cell death-ligand 1 (PD-L1), is approved for use in combination with etoposide and either carboplatin or cisplatin for the first-line treatment of patients with ES-SCLC. On March 10, 2020 French health authorities allowed durvalumab utilization in this setting through a national "early access program" (Autorisation Temporaire d'Utilisation "de cohorte" - ATUc), thus preceding the European market authorization (August 28, 2020). Since 2020 October 1st, durvalumab is used as a post ATU treatment.

Since 2020, French AURA treatment guidelines for SCLC have referenced durvalumab in combination with chemotherapy as one of the first-line treatment options for patients with ES-SCLC based on evidence from the CASPIAN phase III international randomized clinical trial, which demonstrated that adding durvalumab to chemotherapy significantly improved the median overall survival (mOS; hazard ratio: 0.73, 95% confidence interval (CI): 0.59-0.91) over chemotherapy alone.

Results from this CASPIAN study was recently updated with an assessment of 3-year overall survival. As of 2021 March, with a median follow-up 39.4 months, durvalumab plus chemotherapy continued to demonstrate a significant improvement OS versus chemotherapy alone (P = 0.0003). Authors concluded three times more patients were estimated to be alive at 3 years when treated with durvalumab plus chemotherapy versus chemotherapy, with the majority still receiving durvalumab at data cut-off, further establishing durvalumab plus chemotherapy as first-line standard of care for ES-SCLC.

To date, durvalumab has thus been available to first-line ES-SCLC patients and clinicians have the choice between atezolizumab + carboplatin-etoposide, durvalumab + carbo- or cisplatin-etoposide, and carbo- or cisplatin-etoposide alone.

Whereas the safety and efficacy of the durvalumab have been evaluated in clinical trial, data are required to further evaluate the use of durvalumab in real-life condition and in less selected population than in clinical trials, while it received EMA approval in 2020. Some studies with durvalumab were performed in real-life, but only for non-SCLC.

This observational uncontrolled prospective cohort study is conducted to complement evidence from the CASPIAN clinical trial and generate real-world evidence. There is indeed a need to describe durvalumab use in the clinical practice for the treatment of first-line ES-SCLC patients and broaden the CASPIAN results to real-life setting in France.

Therefore, the aim of this study is to describe of platinum-etoposide and durvalumab real-life utilization and effectiveness for first line ES-SCLC.

Outcome Measures

Primary Outcome Measures

  1. The time to first line treatment discontinuation (TTD). [TTD is defined as the time from the index date to the date of last durvalumab infusion (+3 weeks during induction period and +4 weeks during maintenance period) or date of death (up to 36 months)).]

    For patients who start durvalumab at a later cycle than first cycle PE, the index date will be the first infusion of PE. If the treatment is stopped during the first phase of 4 to 6 cycles (induction) with a new re- start of durvalumab and PE, the treatment will be considered as temporary stop. If the treatment is stopped during the durvalumab maintenance with a re-start of durvalumab in monotherapy, the treatment will be also considered as temporary stop. Durvalumab will be considered definitely discontinued when the maintenance phase with durvalumab in monotherapy is stopped and results in a new administration of PE (+/-durvalumab) (subsequent treatment line). For patients still receiving durvalumab at the end of follow-up or when they are lost to follow-up, TTD will be right-censored at the last recorded day of ongoing durvalumab treatment.

Secondary Outcome Measures

  1. Real-world Overall Survival (rwOS) [rwOS rate at 1, 2 and 3 years (rwOS1y, rwOS2y, rwOS3y)]

    rwOS is defined as the time from index date (date of first infusion of durvalumab and/ or platinum-etoposide) to date of death due to any cause. rwOS will be censored on the last date patient is known to be alive. rwOS rate at 1, 2 and 3 years (rwOS1y, rwOS2y, rwOS3y) and median real-world overall survival (mrwOS) will be assessed.

  2. Real world Progression Free Survival (rwPFS) [rwPFS rate at 6, 12, 18, 24 and 36 months (rwPFS6m, rwPFS12m, rwPF18m, rwPFS24m, rwPFS36m) up to 36 months.]

    rwPFS is defined as the time from index date (date of first infusion of durvalumab and/ or platinum-etoposide) to the date of disease progression as assessed by physicians or the date of death, whichever occurs first. rwPFS will be censored on the date of last follow-up. The rwPFS date will be based on the investigator's judgement. The real-world progression may be based on radiological evaluation or clinical judgement, or other measure to compensate absence of RECIST criteria. rwPFS rate at 6, 12, 18, 24 and 36 months (rwPFS6m, rwPFS12m, rwPF18m, rwPFS24m, rwPFS36m) and median rwPFS (mrwPFS) will be assessed.

  3. Patient individual best response [From the start of treatment until disease progression (up to 36 months)..]

    The tumour response will be assessed by investigator as Complete response (CR), Partial response (PR), Stable disease (SD), Progressive disease (PD). The patient individual best response is defined as the best response recorded from the start of treatment until disease progression. The proportion of patients with a CR as best response, with a PR as best response, with SD as best response and with PD as best response will be assessed.

  4. Overall response rate (ORR) [From the start of treatment until disease progression (up to 36 months).]

    ORR is defined as proportion of patients with at least one complete response (CR) or partial response (PR) at least one visit (Paz Ares et al, 2019).

  5. Disease control rate (DCR) [At the end of follow-up (up to 36 months)]

    DCR is defined as the proportion of patients with at least one complete response (CR), partial response (PR) or stable disease.

  6. Time to second real-world progression (rwPFS2) [rwPFS2 (up to 36 months)]

    rwPFS2 is defined as the time from index date (date of first infusion of durvalumab and/ or platinum-etoposide) to the second record of disease progression determined by physicians' assessment, or death. rwPFS2 will be right-censored at the date of last follow-up.
