E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To establish the safety and dose of selumetinib in combination with HAART and to establish evidence of whether AIDS-associated KS lesions respond to (i.e. get smaller with) selumetinib in combination with HAART. |
|
E.2.2 | Secondary objectives of the trial |
To investigate how selumetinib in combination with HAART moves around the body (pharmacokinetics - drug levels of selumetinib, HAART, and HIV viral load and CD4 counts).
To assess the toxicity of selumetinib in combination with HAART.
To monitor any effects that selumetinib has on the body (pharmoacodynamics - serum levels of angiogenic biomarkers, levels of pERK in tumour tissue, changes in peripheral blood mononuclear cells).
To measure progression free survival at 6 months from commencing treatment. |
|
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 |
Patients recruited in Sheffield, Manchester and Leicester will be asked to provide blood for additional laboratory analysis of peripheral blood mononuclear cells (PBMCs). This will explore the effects of pERK inhibition on PBMCs in detail including effects on accessory pathways. This analysis requires blood samples collected freshly and hence is limited to recruiting centres geographically neighbouring Sheffield. |

|
|
E.4 | Principal exclusion criteria |
•HIV viral load > 200 copies/ml. •Active opportunistic infections. •Active hepatitis B, hepatitis C. Any prior exposure to MEK, Ras, or Raf inhibitors or history of hypersensitivity to selumetinib, or any excipient agents. • Any unresolved toxicity > CTCAE Grade 2 from previous anti-cancer therapy, except for alopecia • Cardiac conditions as follows: o Uncontrolled hypertension (BP ≥150/95 mmHg despite medical therapy) o Left ventricular ejection fraction <55% measured by echocardiography o Atrial fibrillation with a ventricular rate >100 bpm on ECG at rest o Symptomatic heart failure (NYHA grade II-IV) o Prior or current cardiomyopathy o Severe valvular heart disease o Uncontrolled angina (Canadian Cardiovascular Society grade II-IV despite medical therapy) o Acute coronary syndrome within 6 months prior to starting treatment •Major surgery within 4 weeks prior to starting selumetinib. •Evidence of any psychological, familial, sociological or geographical condition potentially hampering protocol compliance. •Clinical judgement by the Investigator that the patient should not participate in the study. •Refractory nausea, vomiting, chronic gastrointestinal diseases (e.g. inflammatory bowel disease) or significant bowel resection that would preclude adequate absorption. Ophthalmological conditions as follows: o Intra-ocular pressure >21 mmHg, or uncontrolled glaucoma (irrespective of intra-ocular pressure) o Current or past history of central serous retinopathy or retinal vein occlusion •Treatment with any investigational product within 28 days of registration •Pregnant or breast-feeding women.
Due to higher PK exposure, patients of Asian ethnicity may be at a higher risk of adverse events with selumetinib treatment. Selumetinib is not contra-indicated in patients of Asian ethnicity, but the potential increased risk of toxicity should be considered and included as part of the discussion with the patient prior to receiving informed consent

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome in phase I is the safety and appropriate dosage of selumetinib in combination with HAART. For determining Maximum Tolerated Dose (MTD), defined as the highest dose producing one or less dose limiting toxicity (DLT), DLTs will be assessed during Cycle 1 in Phase I only, (i.e. up to the time of Cycle 2 day 1 assessment). This will be assessed by toxicity using CTCAE v 4.0 criteria.
The primary outcome in phase II is the best tumour response rate with disease assessment based on AIDS Clinical Trials Group Oncology Committee criteria. |
|
E.5.2 | Secondary end point(s) |
The secondary endpoints are: - Toxicity - Progression free survival at 6 months after commencing treatment - Percentage inhibition of pERK in tumour tissue - Downstream proteins, apoptotic pathways and adaptive changes to other MAPK pathways - Percentage changes in serum angiogenic markers - Percentage changes in HIV-viral load and CD4 count
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Progression free survival will be measured for 6 month afters completion of treatment. Other secondary endpoints will be met during the treatment. |

visit of the last subject undergoing the trial

The end of trial is defined as 30 days after the last subject reaches 6 months post study enrolment. This definition allows completion of the secondary end-point of progression free survival rate at 6 months. Patients will continue to be followed up beyond 6 months with data collected by the CTU at 1 yr for supporting evidence for future trial planning. |
