Clinical Trial Summary

Clinical phase 3 study to evaluate the efficacy, tolerability and safety of subcutaneous human immunoglobulin (octanorm) in patients with primary immunodeficiency diseases.

Description:

Octanorm (cutaquig®) is a 16.5% human normal immunoglobulin solution developed by Octapharma for subcutaneous administration (SCIG). It is supplied as a liquid formulation ready to use. One important therapeutic use of immunoglobulins is to provide antibodies to prevent viral and bacterial diseases (replacement therapy). Children and adults with a Primary Immunodeficiency Disease (PID) have an increased risk of recurrent bacterial and viral infections. These diseases can be severe and can lead to substantial morbidity. Responses to antibacterial therapy are often poor. At present, most primary immune deficiencies are not curable, but SCIGs have been shown to decrease the total number of severe infections and the duration of hospitalization. This study evaluated the efficacy, safety and tolerability of octanorm in adult PID patients in an open-label, multi center, phase 3 study with an 8-week wash-in/wash-out period followed by a 6-month efficacy period

3. Patients with body mass index >40 kg/m2

4. Exposure to blood or any blood product or plasma derivatives, other than IVIG treatment of PI, within the past 3 months prior to first infusion of octanorm.

5. Ongoing history of hypersensitivity or persistent reactions to blood or plasma derived products, or any component of the investigational medicinal product (IMP) (such as Polysorbate 80).

6. History of malignancies of lymphoid cells and immunodeficiency with lymphoma.

7. Severe liver function impairment (ALAT 3 times above upper limit of normal).

8. Known protein-losing enteropathies or proteinuria.

9. Presence of renal function impairment (creatinine >120 µM/L or creatinine >1.35 mg/dL), or predisposition for acute renal failure (e.g., any degree of pre-existing renal insufficiency or routine treatment with known nephritic drugs).

10. Treatment with enteral or parenteral steroids for =30 days or when given intermittently or as bolus, at daily doses =0.15 mg/kg. Inhaled corticosteroids are allowed.

11. Patients with chronic obstructive pulmonary disease (COPD) stage Global Initiative for Chronic Obstructive Lung Disease (GOLD) III or IV.

12. Treatment with immunosuppressive drugs.

13. Live viral vaccination (such as measles, rubella, mumps and varicella) within the last 2 months prior to first infusion of octanorm.

14. Treatment with any IMP within 3 months prior to first infusion of octanorm.

15. Presence of any condition that is likely to interfere with the evaluation of study medication or satisfactory conduct of the trial.

16. Known or suspected to abuse alcohol, drugs, psychotropic agents or other chemicals within the past 12 months prior to first infusion of octanorm.

17. Known or suspected human immunodeficiency virus (HIV), hepatitis C virus (HCV), or hepatitis B virus (HBV) infection.

18. Pregnant or nursing women; planned pregnancy during course of the study

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Serious Bacterial Infections Per Person-Year on Treatment	Serious Bacterial Infections defined as bacteraemia/sepsis, bacterial meningitis, osteomyelitis/septic arthritis, bacterial pneumonia, and visceral abscess	Primary Treatment Period (24 Weeks)
Secondary	Number of Patients With Other Infections	The number of patients with all infections of any kind or seriousness.	Primary Treatment Period (24 Weeks)
Secondary	Number of Other Infections	For other infections, the Medical Dictionary for Regulatory Activities (MedDRA) preferred term was used to determine the type of infection. They were grouped into the following categories as determined by a medical expert: Ear infections, eye infections, infections of the gastrointestinal tract, infections of the genitourinary tract, upper respiratory tract infections, lower respiratory tract infections, infections of the skin, and infections not elsewhere classified.	Primary Treatment Period (24 Weeks)
Secondary	Time to Resolution of Infections	Since infections were reported as adverse events, the time to resolution of an infection was the time from the start date of the infection adverse event to the end date of the infection adverse event.	Primary Treatment Period (24 Weeks) and Whole Treatment Period (up to 36 Weeks)
Secondary	Number of Participants Using Antibiotics From 0 to > 20 Days	Number of patients using antibiotics during the whole treatment period (36 weeks) grouped per number of days with antibiotic usage.	Primary Treatment Period (24 Weeks)
Secondary	Annual Rate of Antibiotic Use	The number of antibiotic treatment episodes per person-year of treatment was calculated by the following formula: Total number of antibiotic treatment episodes / patient-years of Octanorm treatment	Primary Treatment Period (24 Weeks)
Secondary	Hospitalizations Due to Infection	Number of days spent in hospital due to infection	Primary Treatment Period (24 Weeks)
Secondary	Rate of Hospitalizations Due to Infection	Annual Rate of Hospitalizations due to Infection	Primary Treatment Period (24 Weeks)
Secondary	Episodes of Fever	Number of episodes of fever	Primary Treatment Period (24 Weeks) and Whole Treatment Period (up to 36 Weeks)
Secondary	Rate of Episodes of Fever	The number of episodes of fever per person-year of treatment was calculated by the following formula: Total number of episodes of fever / patient-years of Octanorm treatment	Primary Treatment Period (24 Weeks)
Secondary	Patients With Days Missed From Work/Study Due to Infections and Treatment	Total number of patients who missed days from work or study due to infections or treatment thereof.	Primary Treatment Period (24 Weeks)
Secondary	Changes in the Subscales of the Form-36 Health Survey Scores From Baseline to the End of the Study	The SF-36-HS consists of 36 items organized into 8 subscales. The 8 subscales could be combined into 2 summary scores, physical and mental. The calculated summary scores were transformed to a range of 0-100, where a higher score indicates better health. A positive change score indicates improvement.	Baseline to the end of study (up to 36 weeks)
Secondary	Trough Levels of Serum Total IgG	Total IgG trough concentrations were measured in serum samples taken before each infusion given at the study site.	At baseline and at last infusion (week 33)
Secondary	Number of Participants Experiencing Treatment-Emergent AEs	TEAEs were classified as temporally associated if the onset was during the infusion or within 72 hours after the end of the infusion.	Up to 36 weeks
Secondary	Proportion of Infusions With at Least 1 Temporally Associated AE	The proportion of infusions with at least 1 temporally associated AE (TAAE) was calculated by dividing the total number of TAAE by the total number of infusions.	Up to 36 weeks
Secondary	Total Number of Adverse Events Regardless of Causality	An AE is any untoward medical occurrence in a study patient receiving an IMP and which does not necessarily have a causal relationship with this treatment.	Up to 36 weeks
Secondary	Number of Related Adverse Events	A related adverse event is an AE for which a causal relationship between the IMP and the AE cannot be ruled out.	Up to 36 weeks
Secondary	Number of Infusions With Infusion Site Reaction	Total number of infusions that triggered an infusion site reaction and number of infusions that triggered mild, moderate, severe or no infusion site reactions.	Up to 36 weeks
Secondary	Annual Rate of Infections	The annual rate of all infections of any kind of seriousness	Up to 36 weeks
