First Line Therapy of Advanced Stage Follicular Lymphoma in Patients < 60 Years Not Eligible fo Standard Immunochemotherapy and in All Patients ≥ 60 Years (GABe2016)
Prospective Randomized Evaluation of Single Agent GA101 Versus GA101 Plus Bendamustine Followed by GA101
The objective of this study is to test the efficacy and toxicity of a combined OBINUTUZUMAB/bendamustine therapy or single agent OBINUTUZUMAB in younger (< 60 years) medically non-fit, 'compromised' patients and in all older patients (≥ 60 years). For the assessment of the antilymphoma activity the overall response rate (ORR)" will be applied as primary endpoint.
Overall response is defined as complete or partial response after 19 - 21 weeks.

Detailed Description
Study design:
This is a randomized, open-label, multicenter phase II trial with a parallel-group design of two groups.
Randomization and Interventions:
Randomization between Obinutuzumab single agent treatment versus Obinutuzumab plus Bendamustine followed by Obinutuzumab
Treatment plans:
Arm A: Obinutuzumab single agent Obinutuzumab flat dose of 1000 mg on Day 1 of each of four 28 -day cycles and on Days 8 and 15 of Cycle 1
If at least 'stable disease':
Obinutuzumab flat dose of 1000 mg at weeks 21, 29, 37 and 45 Arm B: Obinutuzumab plus Bendamustine Obinutuzumab flat dose of 1000 mg on Day 1 of each of four 28 -day cycles and on Days 8 and 15 of Cycle 1 plus Bendamustine 70 mg/m2 iv d1+2 of each of four 28 -day cycles
If at least 'stable disease':
Obinutuzumab flat dose of 1000 mg at weeks 21, 29, 37 and 45
The project attempts to establish an evidence based treatment strategy for medically non-fit advanced stage FL-patients who are not eligible for standard therapeutic immunochemotherapy approaches to improve their long term perspectives.
It will furthermore provide a prospectively generated data set which will link performance in the assessment scores IADL, G8 and CIRS-G to medical fitness as judged by the treating physician. The generated data will allow using geriatric and functional tests to define medical fitness and to provide a more solid basis for future studies.

Bendamustine belongs formally to the alkylators, but has been shown to have a unique mechanism of action.
The dose limiting toxicity of bendamustine is its reversible suppression of bone marrow function with drops in leukocyte and thromobocyte counts.

Comorbidity assessment will be performed by using the Instrumental Activities of Daily Living (=IADL)
Time Frame: Through study completion, up to 6.5 years
|
With the Instrumental Activities of Daily Living (=IADL) the functional status) will be analysed (=instrument to assess independent living skills) The instrument is most useful for identifying how a person is functioning at the present time and for identifying improvement or deterioration over time.
There are 8 domains of function measured with the Lawton IADL scale.
Historically, women were scored on all 8 areas of function; men were not scored in the domains of food preparation, housekeeping, laundering.
However, current recommendations are to assess all domains for both genders.
Persons are scored according to their highest level of functioning in that category.
A summary score ranges from 0 (low function, dependent) to 8 (high function, independent).
|
Through study completion, up to 6.5 years
|
Comorbidity assessment will be performed by using the Cumulative Illness Rating Scale for Geriatrics (CIRS-G)
Time Frame: Through study completion, up to 5 years
|
This can be used to measure the burden of current and chronic illnesses in the older adult.This scoring system measures the chronic medical illness ("morbidity") burden while taking into consideration the severity of chronic diseases in 14 items representing individual body systems. The general rules for severity rating are: 0→No problem affecting that system.
|
Through study completion, up to 5 years
|
Comorbidity assessment will be performed by using the G 8 (=geriatric) 8 screening score
Time Frame: Through study completion, up to 5 years
|
The G8 screening tool was developed to separate fit older cancer patients who were able to receive standard treatment from those that should undergo a geriatric assessment to guide tailoring of therapy.
The assessment includes (instrumental) activities of daily living, cognition, mood, nutritional status, mobility, polypharmacy and social support.
G8 is an independent predictor of mortality within the first year after inclusion (hazard ratio 3.93; 95 % confidence interval 1.67-9.22,
p < 0.001).
The G-8 Score is a screening tool containing 8 questions.
The total G-8 score lies between 0 and 17.
A higher score indicates a better health status.
