E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
|
E.1.1.1 | Medical condition in easily understood language |
An illness that causes bruising and bleeding due to a low platelet count (blood cells essential for normal clotting). |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Blood and lymphatic diseases [C15] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate which first line treatment pathway helps patients with ITP achieve a stable platelet count sooner, measured as survival free from treatment failure (time from randomisation to treatment failure).
To assess this question definitively in a fully powered multicentre randomised controlled trial of the two different treatment pathways in patients followed up for a minimum of 12 months from randomisation. |
|
E.2.2 | Secondary objectives of the trial |
Collecting data on time to treatment failure as measured objectively by a fall in platelet count to <30x10^9/L and need for new treatment Collecting clinical data on additional treatments (including "rescue treatments" such as IVIG (immumoglobulin therapy) Collecting clinical data on cumulative steroid dose. Collecting clinical data on additional investigations, hospital appointments and admissions Collecting patient reported outcomes through standardised questionnaires. Collecting resource use data relating to an NHS/PSS and societal perspective. Collecting data on treatment side effects and adverse events (including bleeding, infections and steroid side effects)
|
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Flight Extra blood sample collection study.
Related objectives: To develop laboratory biomarkers to improve the prediction of clinical outcomes in ITP including illness severity, chronicity and response to treatment. The long term aim is to individualise treatment strategy for patients with ITP, enabling earlier disease control and avoiding side effects of ineffective or unnecessary treatments.
|
|
E.3 | Principal inclusion criteria |
• Patients (males and females) >16 years old with a diagnosis of ITP, a platelet count <30x10^9/L AND a clinical need for first line treatment. • Patients have provided written informed consent
|
|
E.4 | Principal exclusion criteria |
• The exclusion criteria include pregnancy and breastfeeding • Patients with HIV, Hepatitis B or C, or Common Variable immunodeficiency. • Women of child bearing potential require a pregnancy test result within 7 days prior to randomisation to rule out unintended pregnancy • Contraindications to MMF or steroid including patients with hypersensitivity to mycophenolate mofetil, mycophenolic acid or to any of the excipients or active significant infection • Patients not capable of giving informed consent (e.g. due to incapacity) • Patients unwilling to follow contraceptive advice if allocated to MMF treatment arm: WOMEN: Because of the genotoxic and teratogenic potential of MMF, women of childbearing potential must be willing to use a highly effective method of contraception before and six weeks after stopping MMF (hormonal or barrier method of birth control; abstinence). Contraceptive methods that can achieve a failure rate of less than 1% per year when used consistently and correctly are considered as highly effective birth control methods.
NB: Women are considered not of child bearing potential if they are surgically sterile (i.e. they have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are postmenopausal.
MEN: Sexually active men with female partners that are potentially child bearing are recommended to use condoms during treatment and for at least 90 days after cessation of treatment. Condom use applies for both reproductively competent and vasectomised men, because the risks associated with the transfer of seminal fluid also apply to men who have had a vasectomy. In addition, female partners of male patients treated with MMF are recommended to use highly effective contraception during treatment and for a total of 90 days after the last dose of MMF.

E.5 End points |
E.5.1 | Primary end point(s) |
Time from randomisation to treatment failure.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Refractory patients (platelet <30x10^9/L in spite of 2 weeks treatment in the steroid arm or platelet <30x10^9/L in spite of 2 months treatment in the steroid +MMF arm) or who initially respond but then relapse (defined clinically as platelet <30x10^9/L and need for further therapy). |
|
E.5.2 | Secondary end point(s) |
1. Remission rates (pl >30 x10^9/L and at least 2 fold increase from baseline). Complete >100x10^9/L, partial 30-100x10^9/L 2. Time to relapse 3. Time to next therapy 4. Cumulative steroid dose 5. Bleeding events 6. Need for rescue therapies 7. Need for splenectomy 8. Time off work 9. Number of hospital admissions, day unit and clinic attendances 10. Fatigue 11. Quality of life 12. Medication side effects, toxicity or other adverse events (including infection episodes) 13. NHS costs 14. Personal and social costs
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Hospital monitoring of platelet levels is part of routine care for ITP patients and we will collect these details from the medical notes without requiring patients to come in for additional samples to be taken. These locally collected samples may be collected monthly (or less often) for patients believed to be in stable remission and weekly at lower or declining platelet levels. We expect this to allow us to calculate the time in remission and time in relapse with reasonable accuracy over the 12 month follow up period. In addition to clinical data taken from medical records, we will also ask the patients to complete questionnaires on fatigue, quality of life and bleeding scores at baseline, 2, 6, and 12 months. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
In order to confirm the treatment failure endpoint has been reached, we will collect the platelet levels details from sites after all their patients have completed the follow up visits at any given site to the end of the trial. Priority data to be collected would be platelet count data (remission, relapse) and treatment data (treatment taken or not taken). There will be no requirement for patients to come in for additional samples/visits, this information would be available from medical notes. |
