A Study of Mobocertinib in Japanese Adults With Non-Small Cell Lung Cancer

This study is in 2 parts. Different participants will take part in the 1st and 2nd parts of the study.

The main aim of the 1st part of the study is to check how much Mobocertinib adults with non-small cell lung cancer (NSCLC) can receive without getting side effects from it.

The main aim of the 2nd part of the study is to learn if the condition of adults with non-small cell lung cancer improves after treatment with Mobocertinib. Another aim is to continue checking for side effects from Mobocertinib.

In the 1st part of the study, at the first visit, the study doctor will check who can take part. For those that can take part, participants will take a capsule of Mobocertinib once a day for 28 days. This will count as 1 cycle. Different small groups of participants will receive lower to higher doses of Mobocertinib. The study doctors will check for side effects after each dose of TAK 788. In this way, researchers can work out the best dose of Mobocertinib to give participants in the 2nd part of the study.

Participants will visit the clinic 30 days after their treatment has finished for a final check-up.

In the 2nd part of the study, at the first visit, the study doctor will check who can take part. Participants will receive the best dose of Mobocertinib worked out from the 1st part of the study. Participants will receive Mobocertinib in the same way as those from the 1st part of the study. The study doctors will learn if the condition of these participants improves after treatment with Mobocertinib. The study doctors will also check for side effects from Mobocertinib.

After treatment has finished, participants will visit the clinic every 12 weeks until the end of the study.

In both parts of the study, participants can receive Mobocertinib for up to just over 1 year, or longer if their condition stays improved.

About this study

The drug being tested in this study is called Mobocertinib. Mobocertinib is being tested to treat Japanese participants with NSCLC. This study has two parts (Phase 1 part and Phase 2 part), Phase 1 part of this study will look at the safety, efficacy, tolerability and PK of Mobocertinib orally administered once daily, and will determine a RP2D. Phase 2 study will look at the efficacy and safety of Mobocertinib in treatment naive Japanese NSCLC patients with epidermal growth factor receptor (EGFR) exon 20 insertion mutation. All participants will be assigned to Phase 1 part or Phase 2 part and will be asked to take Mobocertinib capsule as following dosage and regimen;

Phase 1 part; Mobocertinib, 40 mg as starting dose, once daily, and escalating up to 160 mg until a Maximum Tolerated Dose (MTD). An expansion phase may be followed at any dose to further confirm safety observations following identification of MTD/RP2D.

Phase 2 part; Mobocertinib, 160 mg, once daily

The study will enroll approximately 58-63 participants (Phase 1 part; 28-33 and Phase 2 part; 30).

This multi-center trial will be conducted in Japan. The overall time to participate in this study of Phase 1 part is approximately 3 years and Phase 2 part is approximately 4 years. Participants will make multiple visits to the clinic in the treatment period, and the post-treatment period including follow-up assessments after the last dose of the study drug.

  22. Phase 2 Part: PFS as Assessed by the Investigator as Per RECIST V1.1

    Time frame: From the first dose of the study drug until PD or death due to any cause (whichever comes first) (Up to 2 years and 9 months, till data cut-off of 08 November 2021

    PFS as assessed by the investigator was defined as the time interval from the start of study treatment until to the first documentation of PD or death due to any cause (whichever comes first) according to RECIST version 1.1.PD (target lesion response): SLD increased by at least 20% from the smallest value on study (including baseline, if that is the smallest). The SLD must also demonstrate an absolute increase of at least 5 mm. PD (non-target lesion response): unequivocal progression of existing non-target lesions.

  23. Phase 2 Part: Overall Survival (OS)

    Time frame: From the start of the study drug up to death due to any cause (Up to 2 years 9 months, till data cut-off of 08 November 2021)

    OS was defined as the interval from the date of the first dose of the study treatment until death due to any cause.

  24. Phase 2 Part: Change From Baseline in Patient-reported Symptoms, Functioning, and Health-related Quality of Life (HRQoL) as Assessed by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30

    Time frame: Baseline and at 30 days after last dose (at Month 19)

    EORTC QLQ-C30, version 3.0 was a cancer-specific questionnaire comprised of 5 functional scales (physical, role, cognitive, emotional, and social functioning); 3 symptom scales (fatigue, pain, and nausea/vomiting); a global health status (GHS)/quality-of-life (QoL) scale; and a six single-item scales (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). GHS/QoL scale has 7 possible scores of responses (1=very poor to 7=excellent). All other items have 4 possible scores (1=not at all, 2=a little, 3=quite a bit, 4=very much). Raw scores converted into scale scores ranging from 0 to 100. For functional and GHS/QoL scales, higher scores represent better HRQoL (positive change from Baseline=improvement), for symptom scales lower scores represent better QoL (i.e., a low level of symptomatology/problems) (negative change from Baseline=improvement), and for six-single item scale, lower scores represent better HRQoL (negative change from Baseline=improvement).

  25. Phase 2 Part: Change From Baseline in Patient-reported Symptoms (Particular Core Symptoms of Lung Cancer), Functioning, and HRQoL as Assessed by the EORTC Lung Cancer Module QLQ-LC13

    Time frame: Baseline and at 30 days after last dose (at Month 19)

    HRQOL scores was assessed with EORTC, it is a lung cancer module QLQ-LC13, version 3.0. QLQ-LC13 included 13 questions (4-point scale where 1=Not at all [best] to 4=Very much [worst]) assessing lung cancer-associated symptoms (cough, hemoptysis, dyspnea, and site-specific pain [chest, arm or shoulder, other parts]), treatment-related side effects (sore mouth, dysphagia, peripheral neuropathy, and alopecia), and use of pain medication. Subscale score range: 0 to 100. Higher symptom score = greater degree of symptom severity.
