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:Cetuximab and gemcitabine in elderly or adult PS2 patients with advanced non-small-cell lung cancer: The cetuximab in advanced lung cancer (CALC1-E and CALC1-PS2) randomized phase II trials.  Two parallel randomized phase 2 trials were performed to choose the optimal way of combining cetuximab with gemcitabine in the first-line treatment of elderly (CALC1-E) and adult PS2 (CALC1-PS2) patients with advanced NSCLC. Stage IV or IIIB NSCLC patients, aged > or =70 years with PS 0-2 for CALC1-E or aged <70 with PS2 for CALC1-PS2, not selected for EGFR expression, were eligible. Patients were randomized to concomitant (gemcitabine, for a maximum of 6 cycles, plus cetuximab until progression) or sequential (gemcitabine, for a maximum of 6 cycles, followed by cetuximab) strategy. A selection design, with 1-year survival rate as the primary endpoint, was applied, requiring 58 elderly and 42 PS2 patients. All planned patients were randomized. In sequential arms, 34.5% and 60.0% patients were not able to receive cetuximab after gemcitabine in CALC1-E and CALC1-PS2, respectively. Survival rates (95% CI) at 1-year for concomitant and sequential arms were 41.4% (23.5-61.1) and 31.0% (15.3-50.8) in CALC1-E and 27.3% (10.7-50.2) and 35.0% (15.4-59.2) in CALC1-PS2. In both studies, survival curves crossed at about 10 months and the worse arm until that time became the better one at 1-year. Toxicity was similar across treatment groups. In concomitant arm of CALC1-E (but not of CALC1-PS2), survival was longer for patients who developed skin toxicity within the first two cycles of treatment. In both groups of patients, sequential strategy cannot be proposed for future trials because of low compliance. Inconsistency of survival outcomes makes also concomitant treatment not a candidate for further testing in unselected elderly and PS2 NSCLC patients. Output:
