      Trial Summary

      The purpose of this study is to evaluate crovalimab for the treatment of a sickle cell pain crisis (also known as a VOE) that requires hospitalisation in adult and adolescent participants with SCD. The primary objective of this study is safety and will additionally evaluate pharmacokinetics (how crovalimab is processed by your body), pharmacodynamics (how your body reacts to crovalimab) and the preliminary efficacy of crovalimab compared with placebo.

      How does the CROSSWALK-a clinical trial work?

      This clinical trial is recruiting people who have sickle cell disease (SCD) and are experiencing a pain attack (crisis) that requires admission to the hospital. 

      The purpose of this clinical trial is to look at the safety and effectiveness of crovalimab, and to understand the way your body processes (pharmacokinetics) and reacts (pharmacodynamics) to crovalimab.

      How do I take part in this clinical trial?

      You will be able to take part in this clinical trial if you:

      • Have been diagnosed with a certain type of SCD (sickle cell anaemia or sickle cell beta zero thalassemia)
      • Are currently experiencing a pain attack (crisis) that requires admission and treatment in the hospital 
      • Are between 12–55 years of age 
      • Are up to date with certain vaccinations

      You will not be eligible to take part in this clinical trial if you:

      • Have had more than 10 pain attacks (crises) requiring a medical visit within the last year 
      • Are experiencing pain that is not a SCD pain attack (crisis)
      • Have an ongoing infection or have had a recent infection

      If you think this clinical trial may be suitable for you and would like to take part, please talk to your doctor. If your doctor thinks that you might be able to take part in this clinical trial, he/she may refer you to the closest clinical trial doctor. They will give you all the information you need to make your decision about taking part in the clinical trial. You can also find the clinical trial locations on this page.

      The clinical trial will begin when you have been admitted to the hospital for treatment of your pain attack (crisis). Your clinical trial doctor will ask you to confirm that you want to take part in the clinical trial and inform you of the risks and benefits. You will also be told what other treatments are available so that you may decide if you still want to take part. 

      You may have some further tests to make sure you will be able to take the treatments given in this clinical trial. Some of these tests or procedures may be part of your regular medical care. They may be done even if you do not take part in the clinical trial. If you have had some of the tests recently, they may not need to be done again.

      For safety reasons while taking part in the clinical trial, women (who are not currently pregnant but can become pregnant) will need to agree to either use a reliable birth control method or not have heterosexual intercourse. 

      What treatment will I be given if I join this clinical trial?

      Everyone who joins this clinical trial will receive ONLY one dose of either:

      • Crovalimab as a single infusion into the vein, OR
      • Placebo as a single infusion into the vein

      You will have a 2 in 3 (67%) chance of being in the crovalimab group and a 1 in 3 (33%) chance of being in the placebo group.

      During the clinical trial, you can continue to have standard treatment for your pain attack (crisis) as recommended by your clinical trial doctor. 

      This is a ‘placebo-controlled’ clinical trial, which means that one of the groups will be given a saline (salt water) infusion with no active ingredients (also known as a ‘placebo’). A placebo is used as a control, to make sure any health effects are from the clinical trial treatment rather than other factors.

      Neither you nor your clinical trial doctor can choose or know the group you are in. An exception is made if your clinical trial doctor needs to know which group you are in for safety reasons.

      How often will I be seen in follow-up appointments and for how long?

      While you are in hospital for treatment of your sickle cell pain attack (crisis), you will be seen by your clinical trial doctor. 

      After being given treatment with crovalimab or placebo, you will have regular tests and check-ups while you are hospitalised until you are well enough to go home from the hospital (discharged). 

      Once you are discharged from the hospital, you will have 3 telephone check-ups and 2 clinic visits with your clinical trial doctor to check on your health and any side effects you may be having. 

      The clinical trial will last for a total of 12 weeks after you are given the clinical trial treatment (crovalimab or placebo).

      What happens if I am unable to take part in this clinical trial?

      If this clinical trial is not suitable for you, you will not be able to take part. Your doctor will suggest other clinical trials that you may be able to take part in or other treatments that you can be given. You will not lose access to any of your regular care.
