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 |
Patients that suffer from a type of cancer, known as sarcoma |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Cancer [C04] |
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 |
This trial’s objective is to demonstrate that the use of ketotifen can improve the efficacy of chemotherapy in patients with sarcoma. |
|
E.2.2 | Secondary objectives of the trial |
A secondary objective of this trial is to demonstrate that measuring and monitoring tumor stiffness using non-invasive, clinically applied ultrasound shear wave elastography can be used as a predictive biomarker. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion criteria include: • patients aged 18 and over, • with a biopsy proven sarcoma subtype, • a performance status (PS) 0 or 1 (ECOG), with • adequate hematologic, renal, hepatic and cardiac function as per internationally accepted standards.
|
|
E.4 | Principal exclusion criteria |
Exclusion criteria: • operable sarcoma, • PS 2 or above, • prior systemic treatment with doxorubicin for sarcoma or treatment with ketotifen in the past for other indications. • Hypersensitivity to the active substance or to any of the excipients (Magnesium stearate, Maize starch, Pregelatinised maize starch, Lactose monohydrate) • Epilepsy • Patients being treated with oral antidiabetic agent(s) • During Pregnancy and Breastfeeding.

|
E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint: confirm that TME reprogramming (change in mechanical properties of tumor) can be objectively assessed on ultrasound measurements of elastography after at least 3 cycles of combination treatment. This marker will represent a mechanical biomarker of response to treatment.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
All patients will be subjected to ultrasound imaging after completing 3 cycles of doxorubicin or combination (doxorubicin + ketotifen) treatment and a final measurement will be taken by the completion of 6 cycles. |
|
E.5.2 | Secondary end point(s) |
Secondary endpoints: (i) objective response rate (ORR) (which accounts for complete and partial responses) per RECIST 1.1, progression-free and OS and comparison with historical controls. (ii) document potential toxicity from the combination of ketotifen with standard of care systemic treatments.
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
A final analysis is planned after completion of treatment schedule. |

E.8.8 |
Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The rationale for assessment after the first 3 cycles is that it provides enough time for the drugs to have an effect. At the same time this is the number of cycles that most patients are likely to complete as some patients will not tolerate chemotherapy until cycle 6. |
