Your goal is to extract structured information from the user's input that matches the form described below. When extracting information please make sure it matches the type information exactly. Do not add any attributes that do not appear in the schema shown below.

```TypeScript

 { // Information on the clinical trial characteristics from the abstract
 conditions: string // The condition or disease being treated in the clinical trial
 drug_or_intervention: string // The drug or intervention used in the clinical trial
}
```


Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them. All output must be in JSON format and follow the schema specified above. Wrap the JSON in <json> tags.



Input:Abatacept for Crohn's disease and ulcerative colitis.  The efficacy of abatacept, a selective costimulation modulator, in Crohn's disease (CD) and ulcerative colitis (UC) is unknown. Four placebo-controlled trials evaluated the efficacy and safety of abatacept as induction (IP) and maintenance (MP) therapy in adults with active, moderate-to-severe CD (CD-IP; CD-MP) and UC (UC-IP1; UC-MP). In CD-IP and UC-IP1, 451 patients with CD and 490 patients with UC were randomized to abatacept 30, 10, or 3 mg/kg (according to body weight) or placebo, and dosed at weeks 0, 2, 4, and 8. In MP, 90 patients with CD and 131 patients with UC who responded to abatacept at week 12 in the induction trials were randomized to abatacept 10 mg/kg or placebo every 4 weeks through week 52. In CD-IP, 17.2%, 10.2%, and 15.5% of patients receiving abatacept 30, 10, and 3 mg/kg achieved a clinical response at weeks 8 and 12, vs 14.4% receiving placebo (P = .611, P = .311, and P = .812, respectively). In UC-IP1, 21.4%, 19.0%, and 20.3% of patients receiving abatacept 30, 10, and 3 mg/kg achieved a clinical response at week 12, vs 29.5% receiving placebo (P = .124, P = .043, and P = .158, respectively). In CD-MP, 23.8% vs 11.1% of abatacept vs placebo patients were in remission at week 52. In UC-MP, 12.5% vs 14.1% of patients receiving abatacept vs placebo were in remission at week 52. Safety generally was comparable between groups. The studies showed that abatacept is not efficacious for the treatment of moderate-to-severe CD or UC. Output:
