Background and study aims
Non-Hodgkins lymphoma is a type of cancer that affects the network of vessels and glands throughout the body. We are comparing a drug called biosimilar rituximab against rituximab, both given with chemotherapy for patients with non-Hodgkins lymphoma. The main purpose of the study is to prove that the treatment with biosimilar rituximab has similar effects as the treatment with rituximab. Additionally, we will check the time taken for this disease to progress and review the safety of both drugs.
Who can participate?
The study aims to enrol 250 patients, men and women, aged 18 to 65, recently found to have this disease and who have not received any treatment for it before.
What does the study involve?
Patients are randomly allocated to one of two groups: one will be treated with biosmiliar rituximab and the other one with rituximab, both treatments combined with CHOP chemotherapy, on day 1 every 3 weeks for 6 cycles. There will be 3 study periods: screening (various tests will be done including a complete physical examination), treatment (visit the clinic every 3 weeks to undergo 6 cycles of treatment) and a final visit (30 days after completion of the treatment). After this, patients will be followed up every 3 months until 9 months after the last dose of chemotherapy.
What are the possible benefits and risks of participating?
Taking part in this study may or may not make your health better. This study might contribute to the development of a drug that will lower the cost of currently available treatment options. This information may help future patients. Patients may have side effects caused by the drug rituximab. The main ones are due to the drip (infusion of the drug) given during the treatment. These are mainly seen with the first drip and rarely require drug treatment to be stopped. Also, low blood pressure, fever, chills, episodes of shaking/shivering, skin rash, tightening of the airways and swelling of the deeper layers of the skin have been observed with this drug infusion. Possible serious side effects of CHOP chemotherapy include infection, bleeding problems, tissue injury, early menopause, heart failure and bladder problems. Common side effects of CHOP chemotherapy include nausea and vomiting, fevers and chills, skin rash, hair loss, mouth sores, fatigue, platelets in your blood may decrease (platelets help your blood clot if you cut yourself and you may bruise or bleed more easily than usual), severe constipation, numbness or tingling of fingers or toes, pink or reddish urine for 1-2 days after treatment, sugar control may be affected in people with diabetes, increased energy and difficulty sleeping.
Where is the study run from?
The study is run at different hospitals and clinics in Argentina, Brazil, Mexico, Venezuela, Paraguay, Indonesia, India, Colombia and South Africa.
When is the study starting and how long is it expected to run for?
The study started in January 2013 in Paraguay, April 2013 in Argentina, May 2013 in Indonesia and Mexico. It is expected that study will start in August 2013 in Brazil and South Africa and at the end of the year in Venezuela, India and Colombia. The study will be recruiting patients until December 2014.
Who is funding the study?
The present study is sponsored by mAbxience SA (Switzerland) and co-sponsors as this is a co-development study.

| Scientific title | A randomized, double-blind, phase III study comparing biosimilar rituximab (RTXM83) plus CHOP chemotherapy versus a reference rituximab plus CHOP (R-CHOP) in patients with Diffuse Large B-Cell Lymphoma (DLBCL) given as first line |
| Study objectives | The primary endpoint of the investigation is to determine if the response rate obtained with RXM83 combined with CHOP is non inferior to the response rate obtained with reference rituximab combined with CHOP The present study is a non inferiority trial and the study hypothesis is the following: H0: pc ≥ pe + δ vs. H1: pc < pe + δ where, pe: proportion of successes in the experimental group (RTXM83+CHOP) pc: proportion of successes in the control group (Reference Rituximab+CHOP) Type I error: the difference pc-pe is less than δ when in fact the difference is greater than or equal to δ ie, we choose the experimental treatment when the control treatment is actually substantially better. Type II error: the difference -pe is greater than or equal to δ when it is actually lest than δ ie, we choose the control treatment when the experimental treatment is essentially just as good. |
