7. Product details
1. Why am I using SIMPONI/SIMPONI IV?
SIMPONI/SIMPONI IV contains the active ingredient golimumab (rmc) which is a human monoclonal antibody that is produced by recombinant technology. Monoclonal antibodies are proteins that recognise and bind to other specific proteins in the body. Golimumab works by binding to a specific protein in the body called tumour necrosis factor (TNF) alpha.
SIMPONI/SIMPONI IV is used to adult patients with:
- Rheumatoid arthritis, an inflammatory disease of the joints.
If you have active rheumatoid arthritis, you will be given SIMPONI/SIMPONI IV, which you will take in combination with methotrexate. - Psoriatic arthritis, an inflammatory disease of the joints in which psoriasis usually occurs in association with arthritis. Often the fingers and toes are affected, although it may occur in other parts of the body.
If you have active psoriatic arthritis, you will be given SIMPONI/SIMPONI IV alone or in combination with methotrexate. - Ankylosing spondylitis, an inflammatory disease of the spine.
SIMPONI is also used to treat adult patients with:
- Non-radiographic axial spondyloarthritis, an inflammatory disease of the spine.
- Ulcerative colitis, an inflammatory disease of the bowel.
- If you have moderate to severe ulcerative colitis that is active and has not responded to other medications, you will be given SIMPONI.
In these diseases, the body produces too much TNF. Too much of this substance causes your body's immune system to attack healthy tissue and results in inflammation. Blocking TNF-alpha with SIMPONI/SIMPONI IV can reduce the signs and symptoms of your disease by reducing the inflammation associated with these diseases, but it can also reduce your immune system's ability to fight off infections.
2. What should I know before I use SIMPONI/SIMPONI IV?
Warnings
Do not use SIMPONI/SIMPONI IV if:
- you are allergic to golimumab, or any of the ingredients listed at the end of this leaflet.
Always check the ingredients to make sure you can use this medicine. - you have a severe infection including tuberculosis, infection of the bloodstream (sepsis), and other infections that can occur when the body's natural defences are lowered.
SIMPONI/SIMPONI IV can affect your body's ability to fight a serious infection. If you are not sure whether you have a serious infection, check with your doctor. - you are already taking another medicine for arthritis, which contains either of the substances called anakinra (Kineret) or abatacept (Orencia).
- you have moderate to severe heart failure.
Check with your doctor if you:
- have any kind of infection even if it is very minor, or have an infection that won't go away, or a history of infection that keeps coming back.
SIMPONI/SIMPONI IV is a medicine that affects your immune system. SIMPONI/SIMPONI IV can lower the ability of your immune system to fight infections. Some patients have had serious infections while receiving SIMPONI/SIMPONI IV, including tuberculosis, and systemic bacterial and fungal infections. Some patients have died from these serious infections. - have had TB (tuberculosis) or have recently been near anyone who might have TB. Your doctor will evaluate you for TB and perform a skin or a blood test. If your doctor feels that you are at risk for TB, he or she may start treating you for TB before you begin SIMPONI/SIMPONI IV therapy.
- have lived in or travelled to an area where infections called histoplasmosis, coccidioidomycosis, or blastomycosis are common. These infections are caused by a fungus that can affect the lungs or other parts of your body. Ask your doctor if you don't know whether these infections are common in the area in which you have lived or travelled.
- have or have had a hepatitis B infection, or have been in contact with someone who has this condition. Treatment with TNF-blocking agents such as SIMPONI/SIMPONI IV may result in reactivation of hepatitis B in patients who carry this virus. If you know or suspect you may be a carrier of the hepatitis B virus, be sure to tell your doctor about this as this may impact the decision to start or continue treatment with SIMPONI/SIMPONI IV. Your doctor should do a blood test for the hepatitis B virus before you start treatment with SIMPONI/SIMPONI IV.
- have heart failure, or if you previously had or currently have any heart condition. If you develop new or worsening symptoms of heart failure, such as shortness of breath or swelling of your feet, you must notify your doctor.
- have or have had a condition that affects your nervous system, such as multiple sclerosis or Guillain-Barre syndrome. You should tell your doctor if you experience any weakness in your arms or legs, numbness, tingling, or visual disturbances.
- have or have had any type of cancer. A type of blood cancer called lymphoma has been reported in patients receiving TNF alpha blockers. The reports are rare but more frequent than expected for people in general. Cancers, other than lymphoma, have also been reported.
- have recently received or are scheduled to receive a vaccine. Patients receiving SIMPONI/SIMPONI IV should not receive some type of vaccines.
- have recently received or are scheduled to receive treatment with a therapeutic infectious agent (such as BCG instillation used for the treatment of cancer).
- have a latex allergy. The needle cover on the pre-filled syringe and the injector pen contains dry natural rubber.
- blood disorders, or a history of blood disorders.
- You have ever received other TNF alpha antagonist treatments such as infliximab (REMICADE) or adalimumab (HUMIRA)
- take any medicines for any other condition.
During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?
Cancer
- In clinical studies, reports of blood cancer called lymphoma were more frequent in patients on SIMPONI/SIMPONI IV than for people in general. People who have been treated for rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis for a long time, particularly those with highly active disease may be more prone to develop lymphoma.
- Cancers, other than lymphoma, have also been reported in patients treated with SIMPONI/SIMPONI IV or other TNF blockers. In a study of SIMPONI/SIMPONI IV in patients with severe persistent asthma, cancers occurred in SIMPONI/SIMPONI IV-treated patients, but not in control-treated patients. If you have severe persistent asthma, you should discuss with your doctor whether SIMPONI/SIMPONI IV is appropriate for you.
- There have been cases of cancers, including unusual types, in children and teenage patients taking TNF-blocking agents, which sometimes resulted in death. For children and adults taking TNF blocker medicines, the chances of getting lymphoma or others cancers may increase.
- On rare occasions, a specific and severe type of lymphoma called hepatosplenic T-cell lymphoma has been observed in patients taking other TNF blockers. Most of these patients were adolescent or young adult males. This type of cancer has usually resulted in death. Almost all of these patients had also received drugs known as azathioprine or 6-mercaptopurine. Tell your doctor if you are taking azathioprine or 6-mercaptopurine with SIMPONI/SIMPONI IV. Talk to your doctor if you are concerned about this.
- Some patients treated with SIMPONI/SIMPONI IV have developed certain kinds of skin cancer like melanoma.
You should also tell your doctor if you have had or develop lymphoma or other cancers while you are taking SIMPONI/SIMPONI IV. Whether you decide to use SIMPONI/SIMPONI IV or not, you should discuss with your doctor the cancer screening measures and impact of the life style choices on the risk of developing cancer.
During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Check with your doctor if you are pregnant or intend to become pregnant.
The use of this medicine in pregnant women is not recommended. SIMPONI/SIMPONI IV should only be used during pregnancy if clearly needed.
Use appropriate contraception to avoid becoming pregnant while using SIMPONI/SIMPONI IV and for at least 6 months after the last dose.
If you received SIMPONI/SIMPONI IV while you were pregnant your baby may be at higher risk of getting an infection for up to approximately six months after the last dose you received during pregnancy. It is important to tell your baby's doctor and other health care professionals about your SIMPONI/SIMPONI IV use before the baby receives any vaccine as certain vaccines may put your baby at higher risk for infections.
Talk to your doctor if you are breastfeeding or intend to breastfeed.
It is not known whether SIMPONI/SIMPONI IV passes into breast milk. If you are breastfeeding, your doctor may advise you to stop breastfeeding while you are using this medicine, and for at least 6 months after the last dose.

SIMPONI/SIMPONI IV is not recommended for use in children below age 18 due to a lack of data on efficacy and safety.
3. What if I am taking other medicines?
Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines may interfere with SIMPONI/SIMPONI IV and affect how it works. These include any other medicines to treat
- rheumatoid arthritis
- psoriatic arthritis
- ankylosing spondylitis
- ulcerative colitis
Especially, tell your doctor or pharmacist if you are taking a medicine containing the substance anakinra (Kineret), abatacept (Orencia) or rituximab (Mabthera).
SIMPONI/SIMPONI IV should not be taken together with anakinra or abatacept.
Also, tell your doctor if you are taking other medications that affect your immune system.
Tell your doctor if you are scheduled to receive any vaccines. Patient receiving SIMPONI/SIMPONI IV should not receive some type of vaccines.
Using SIMPONI/SIMPONI IV together with any of these medicines may increase the risk of infection.
Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect SIMPONI/SIMPONI IV.

- Use appropriate contraception to avoid becoming pregnant while using SIMPONI/SIMPONI IV and for at least 6 months after the last dose.
- Tell your doctor if you did receive SIMPONI/SIMPONI IV while you were pregnant as your baby may be at higher risk for getting an infection. It is important to tell your baby's doctor and other health care professionals about your SIMPONI/SIMPONI IV use so they can decide when your baby should receive any vaccine.
- Keep all of your doctor's appointments so that your progress can be checked.
Call your doctor straight away if:
- symptoms of hepatitis B (upset stomach, loss of appetite, vomiting, tiredness, dark yellow or brown urine, and yellow eyes or skin) appear.
- symptoms of TB (persistent cough, weight loss, listlessness, fever), or any other infection appear
- you have symptoms such as persistent fever, sore throat, bruising, bleeding or paleness. These symptoms may be due to the development of a blood disorder, which may need close monitoring by your doctor.
- if you develop a skin rash or hives. Some patients may get allergic reactions to SIMPONI. Some of these reactions may be serious. If an allergic reaction occurs while getting a SIMPONI infusion or shortly afterwards, your doctor may decide to stop your SIMPONI infusion and/or give you medication to treat the reaction.
- you notice any new skin lesions during or after therapy or if existing lesions change appearance. See additional information under Section 2 What should I know before I use SIMPONI/SIMPONI IV? – Cancer.
Remind any doctor, dentist or pharmacist you visit that you are using SIMPONI/SIMPONI IV.

Table 2 summarises the adverse drug reactions that occurred at a rate equal to or higher than 1% in the Simponi IV ± MTX with a higher incidence than in the placebo ± MTX group during the placebo-controlled period of the phase 3 Simponi IV trials in the RA, PsA and AS with a 2 mg/kg dosing regimen.
Table 3 summarises adverse drug reactions observed in phase 2/3 clinical studies from the Simponi-treated and Simponi IV-treated patients with RA, PsA, AS, UC, and severe persistent asthma and with active non-radiographic axial spondyloarthritis (nr-Axial SpA). Within the designated system organ classes, the adverse reactions are listed under headings of frequency, using the following convention: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to < 1/1,000); very rare (< 1/10,000); not known (cannot be estimated from the available data). Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.
In general, the overall safety profile was similar for patients receiving golimumab via the SC or IV routes of administration. The data described in the following section reflect adverse reactions from the SC phase 2 and 3 clinical trials with differences observed with the IV phase 3 clinical trials noted.
In GO-FORWARD and GO-BEFORE, the proportions of patients achieving an ACR 20, 50 or 70 response were maintained through Week 104.
In GO-FORWARD and GO-BEFORE, the percent improvement in the ACR components measured (swollen joint count, tender joint count and CRP) observed at week 24 was maintained at week 52 and week 104.
In GO-BEFORE, Simponi 50 mg + MTX demonstrated significant inhibition in radiographic progression compared with placebo + MTX among patients with abnormal (> 1.0 mg/dL) CRP (mean (SD) change from baseline in total vdH-S score 1.3 (7.0) versus 2.2 (5.6) respectively, p=0.010). A greater number of patients in the Simponi 50 mg + MTX group (71%) had no new erosions in uninvolved joints at baseline compared to MTX alone (54%). There was a significantly greater number of subjects in the Simponi 50 mg + MTX group without an increase from baseline in total vdH-S score compared with the placebo + MTX group (71% versus 54% respectively, p = 0.003).
The percentage of patients achieving ACR 50 and ACR 70 responses was also greater in the Simponi IV + MTX group than in the placebo IV + MTX group.
At week 14, Simponi IV MTX treatment also resulted in significantly greater improvement for each ACR component compared with treatment with placebo + MTX (Table 9). The improvement in all ACR components observed at week 24 was maintained at each visit through week 52.
At week 24, a significantly greater proportion of patients in the Simponi IV + MTX group (71%) had no progression of structural damage (change in the total vdH-S score ≤ 0), compared to 57% of patients in the placebo + MTX group (p-value = 0.001).
Improvements in key measures of disease activity were observed at the first assessment (week 4) after the initial Simponi administration and were maintained through week 24. Similar ACR 20 responses at week 14 were observed in patients with different PsA subtypes including polyarticular arthritis with no rheumatoid nodules, asymmetric peripheral arthritis, DIP arthritis, and spondylitis with peripheral arthritis. The number of patients with arthritis mutilans was too small to allow meaningful assessment. Responses observed in the Simponi-treated groups were similar in patients receiving and not receiving concomitant MTX. Among 146 patients randomised to Simponi 50 mg, 70 were still on this treatment at week 104. Of these 70 patients, 64, 46 and 31 patients had an ACR 20/50/70 response, respectively.
A significantly greater number of patients in the Simponi 50 mg group had no new erosions or no new joint space narrowing (JSN) in joints that were uninvolved at baseline compared to placebo (see Table 13).
There was a significantly greater number of subjects in the Simponi 50 mg group without an increase from baseline in total PsA modified vdH-S score compared with the placebo group (79% versus 63% respectively, p=0.007).
The percentage of patients achieving ACR 20 responses by visit through week 24 for the GO-VIBRANT is shown in Figure 2.
Patients with enthesitis at baseline were evaluated for mean improvement using the Leeds Enthesitis Index (LEI) on a scale of 0-6. Simponi IV-treated patients showed a significantly greater improvement in enthesitis, with a mean reduction of 1.8 as compared with a mean reduction in placebo-treated patients of 0.8 at week 14. Patients with dactylitis at baseline were evaluated for mean improvement on a scale of 0-60. Simponi IV-treated patients showed a significantly greater improvement, with a mean reduction of 7.8 compared with a mean reduction of 2.8 in placebo-treated patients at week 14.
Among patients with ≥ 1 joint with a JSN score of 0 at baseline (92%), a greater proportion of Simponi IV-treated patients showed no new erosions and no new joint space narrowing compared with placebo-treated patients at week 24 (see Table 16).
At week 24, a greater proportion of patients in the Simponi IV-treated group (72%) had no progression of structural damage (change in the total modified vdH-S score ≤ 0), compared to 43% of patients in the placebo group (p < 0.001).
Compared with placebo, Simponi treatment resulted in a significant improvement in signs and symptoms as demonstrated by the ASAS and BASDAI scores at weeks 14 and 24. Patients treated with Simponi achieved significantly greater improvement in all ASAS 20 components compared with placebo. Improvements in key measures of disease activity were observed at the first assessment (week 4) after the initial Simponi administration and were maintained through week 24. Consistent efficacy was seen in patients regardless of HLA-B27 antigen status or baseline CRP levels as assessed by ASAS 20 responses at week 14.
Statistically significant improvements in signs and symptoms of severe active nr-Axial-SpA were demonstrated in patients treated with Simponi 50 mg compared to placebo at week 16 (Table 18). Improvements were observed at the first assessment (week 4) after the initial Simponi administration. SPARCC score as measured by MRI showed statistically significant reductions in SI joint inflammation at week 16 in patients treated with Simponi 50 mg compared to placebo (Table 18). Pain as assessed by the Total Back Pain and Nocturnal Back Pain VAS, and disease activity as measured by ASDAS-C also showed improvement from baseline to week 16 in patients treated with Simponi 50 mg compared to placebo.
The percentage of patients achieving ASAS 20 responses by visit through week 16 for GO-ALIVE is shown in Figure 3. ASAS 20 responses were observed in 37% of patients treated with Simponi IV at the first assessment (week 2) compared with 19% placebo-treated patients.
Table 20 shows the improvements in the components of the ASAS response criteria and other measures of disease activity, BASMI and BASDAI score at week 16 for the Simponi IV and placebo groups.
In PURSUIT-Induction, a greater reduction in the partial Mayo score was evident as early as week 2 in the Simponi 200/100 mg group compared with the placebo group and this reduction was maintained through week 6.
