Brief summary

The purpose of this trial was to assess the ability of eltrombopag to induce sustained treatment-free remission in immune thrombocytopenia purpura (ITP) subjects who relapsed or failed to respond to an initial treatment with steroids.

Detailed description

Protocol Amendment 01 added a follow-up period of 12 months for patients with sustained response off treatment at month 12 to obtain further data on response duration. The starting dose was eltrombopag 50 mg daily (25 mg daily for Asian patients and 12.5 mg daily for Japanese patients in Japan). The starting dose for this study was consistent with the dosing guidelines approved for eltrombopag use in ITP. An increase of eltrombopag dose up to 75 mg was allowed for patients who did not respond to standard-dosage treatment and to reduce the risk of bleeding. The rationale for this increased dose was to use the minimal efficacious dosage of eltrombopag in order to achieve a platelet count ≥ 100×10\^9/L and maintain it around 100×10\^9/L (no counts below 70×10\^9/L) for 2 months in order to allow patients to start the eltrombopag tapering and withdrawal process. Patients who reached a platelet count of \>= 100 × 10\^9/L and maintained counts around 100×10\^9/L for 2 months with no platelet count \< 70 × 10\^9/L were eligible for tapering-off and treatment discontinuation, which occurred via 25 mg reduction every 2 weeks up to 25 mg on alternate days for 2 weeks until treatment discontinuation. Patients who successfully discontinue eltrombopag and maintained platelet count \>= 30 × 10\^9/L in the absence of bleeding or use of rescue therapy were followed to month 12. If a relapse (defined as platelet count \<30 × 10\^9/L) occurred during the 12-month treatment period, they were offered a new course of eltrombopag treatment within this timeframe at the appropriate starting dose. If a patient relapsed in the post 12-month follow-up period, no further attempts for tapering and achieving sustained response off treatment were made. The taper-off scheme followed recommendations within the current established dosing regimen for when to consider dose adjustment.

Overall Change of Treatment Satisfaction Using Treatment Satisfaction Questionnaire (TSQM-9)Baseline to month 12 (End of Treatment Visit for non-responders) and 24 (End of Treatment Visit for responders), assessed up to 12 months for non-responders and up to 24 months for respondersThe Treatment Satisfaction Questionnaire for Medication (TSQM-9) is a psychometric measure of a patient's satisfaction with medication. It consists of 3 subscales: effectiveness, convenience and global satisfaction. The scores were computed by adding items for each domain, i.e. 1 to 3 for effectiveness, 4 - 6 for convenience and 7 to 9 for global satisfaction. The lowest possible score (1 for each item and 3 for all 3 subscales) was subtracted from the composite score and divided by the greatest possible score range. The greatest range was (7-1) X 3 items = 18 for the effectiveness and convenience, and (5-1) x 3 items = 12 for global satisfaction. This provided a transformed score between 0 and 1 that was then multiplied by 100. A positive change from baseline indicates improvement.

Change From Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) Questionaire

The Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-Fatigue©) is a 13- item questionnaire that assesses self-reported fatigue and its impact upon daily activities over the past 7 days. FACIT-fatigue is scored using a 4-point Likert scale. Items are scored as follows: 4 = Not At All; 3 = A Little Bit; 2 = Somewhat; 1 = Quite A Bit; 0 = Very Much, EXCEPT items #7 and #8 which are reversed scored. Score range from 0-52. A score of less than 30 indicates severe fatigue. The higher the score, the better the quality of life (less fatigue).

Time frame: Baseline to month 3, 6, 9, 12 (End of Treatment Visit for non-responders), 15, 18, 21 and 24 (End of Treatment Visit for responders), assessed up to 12 months for non-responders and up to 24 months for responders

Change From Baseline in Short Form 36 Health Survey (SF-36v2) Questionnaire: Bodily Pain (BP) Score

The SF-36 Scale is a 36-item, patient-reported survey which measures overall quality of life. It consists of 8 subscales (bodily pain (BP), general health (GH), mental health (MH), physical functioning (PF), role emotional (SE), role physical (RP), social role functioning (SF) and vitality (VT)) which can be aggregated to derive a physical-component summary (PCS) score and a mental-component score (MCS). The SF-36 is scored using norm-based scoring procedures: each sub-scale score ranges from 0 to 10, and the composite score ranges from 0 to 100. Higher scores indicative of better HRQoL.

Time frame: Baseline to month 3, 6, 9, 12 (End of Treatment Visit for non-responders), 15, 18, 21 and 24 (End of Treatment Visit for responders), assessed up to 12 months for non-responders and up to 24 months for responders

Population: Full Analysis Set. Only participants with a value at both Baseline and post-baseline visit included.

Estimated Median Duration of Sustained Response Off Treatment (SRoT) for Participants With Sustained Response Off Treatment at Month 12 and Who Enter 12 Months Follow-up Period

Sustained response off treatment (SRoT) was defined as: reaching platelet count \>= 100×10\^9/L (complete response \[CR\]) and then maintaining platelet counts around 100×10\^9/L for 2 months (no counts below 70×10\^9/L), AND then tapering off the drug until treatment discontinuation while maintaining platelet count \>= 30×10\^9/L in the absence of bleeding (no bleeding AEs) or use of any rescue therapy. Patients with SRoT until month 12 who entered follow-up and did not relapse by cut-off date/Month 24 were censored at the earliest of discontinuation date/death date/Month 24 platelet assessment date/cutoff date. Patients with SRoT until Month 12 patients who did not enter or do not yet have data in follow-up phase are censored at their Month 12 platelet assessment date.

Overall Change of Treatment Satisfaction Using Treatment Satisfaction Questionnaire (TSQM-9)

The Treatment Satisfaction Questionnaire for Medication (TSQM-9) is a psychometric measure of a patient's satisfaction with medication. It consists of 3 subscales: effectiveness, convenience and global satisfaction. The scores were computed by adding items for each domain, i.e. 1 to 3 for effectiveness, 4 - 6 for convenience and 7 to 9 for global satisfaction. The lowest possible score (1 for each item and 3 for all 3 subscales) was subtracted from the composite score and divided by the greatest possible score range. The greatest range was (7-1) X 3 items = 18 for the effectiveness and convenience, and (5-1) x 3 items = 12 for global satisfaction. This provided a transformed score between 0 and 1 that was then multiplied by 100. A positive change from baseline indicates improvement.

Time frame: Baseline to month 12 (End of Treatment Visit for non-responders) and 24 (End of Treatment Visit for responders), assessed up to 12 months for non-responders and up to 24 months for responders

Population: Full Analysis Set. Only participants with a value at both Baseline and post-baseline visit included.

Percentage of Participants With Worst Post-baseline Value in Functional Assessment of Cancer Therapy-G (GP5)

The GP5 is a single question used to assess the overall bothersomeness of treatment side effects. The GP5 is scored using a 5-point rating scale (0 = not at all; 1 = a little bit; 2 = somewhat; 3 = quite a bit; and 4 = very much), where lower scores reflect less bothersomeness from treatment side effects.

Time frame: Baseline to end of treatment visit, assessed up to 12 months for non-responders and up to 24 months for responders

All Collected Deaths

On-treatment deaths were reported from the date of first dose of eltrombopag to 30 days after the date of the last non-zero dose of eltrombopag for patients who discontinued on or before month 12 (i.e., non-responders). For patients ongoing at month 12, the on-treatment period lasted until the cut-off date for the primary analysis (22-Oct-2021; approximately 35 months), as a patient could restart treatment at any time during study. Post-treatment deaths were collected in the post treatment period from 31 days after last dose of study medication until the cut-off date for the primary analysis (22-Oct-2021; approximately 35 months). These are not considered Adverse Events.

Time frame: On-treatment deaths: Up to approximately 35 months. Post-treatment deaths: Up to approximately 35 months
