Summary Report*

All the details on study of Exemestane with Celecoxib as Neoadjuvant Treatment in Postmenopausal Women.

Here is a summary of the study examining the use of Exemestane combined with Celecoxib as a neoadjuvant treatment in postmenopausal women with breast cancer based on the provided documents:

This study examined the use of Exemestane combined with Celecoxib as a neoadjuvant treatment in postmenopausal women with stage I, Ill and IV breast cancer. The study was registered on ClinicalTrials.gov under the identifier NCT00201773 and was conducted by the Ohio State University Comprehensive Cancer Center.

Rationale

In postmenopausal women, the main source of estrogen is through the conversion of androgens, or sex hormones produced by the adrenal glands, into estrogens. This conversion is carried out by an enzyme called aromatase. Exemestane is an aromatase inhibitor which blocks the production of estrogens by inhibiting aromatase. Research indicates that the gene responsible for aromatase activity is CYP19. Therefore, Exemestane helps to inhibit aromatase activity through CYP019.

Along with CYP019, another gene associated with breast cancer is an overexpression of COX-2 enzymes. Research suggests that COX-2 overexpression can cause cancer cell division, increased blood flow to tumors, and metastases. Celecoxib is a COX-2 inhibitor which blocks COX-2 activity. Compared to other non-steroidal anti-inflammatory drugs (NSAIDs), Celecoxib produces fewer side effects.

The rationale of this study was to build on previous research to test the combination of Exemestane (an aromatase inhibitor) and Celecoxib (a COX-2 inhibitor) as a neoadjuvant treatment for breast cancer in postmenopausal women.

Study Design

This was a single center, open label, non-randomized interventional study.

The primary purpose was treatment.

The allocation was non-randomized. All participants received the treatment.

The study used a single group assignment. There was no control group or randomization. The masking was open label, meaning the participants and researchers were aware of the treatment.

Participants

The study enrolled postmenopausal women aged 18 years and older with stage Il, Ill and IV breast cancer. Women who were pregnant or breastfeeding were excluded. A total of 11 patients were enrolled.

Treatment

Patients received oral Exemestane 25 mg once daily for 16 weeks.

Starting at week 9, they also received oral Celecoxib 400 mg (two 200 mg capsules) twice daily for 8 weeks.

Therefore, from weeks 9-16 patients received a combination of both Exemestane and Celecoxib.

Several tests and exams were conducted throughout the study to monitor the patients, including a biopsy performed after the first 8 weeks on Exemestane alone.

After 16 weeks on Exemestane and Celecoxib, patients underwent breast cancer surgery.

Outcome Measures

The primary outcome measure was to evaluate the number of patients with decreased gene expression of CYP19 in breast cancer by adding a COX-2 inhibitor (Celecoxib) to Exemestane.

Gene expression was analyzed from tissue samples collected at the time of surgery after 16 weeks of treatment.

Secondary outcome measures included evaluating the response rate to neoadjuvant Exemestane and Celecoxib using the Response Evaluation Criteria in Solid Tumors (RECIST 1.0).

Response was evaluated by MRI and categorized as complete response, partial response, stable disease, or progressive disease.

Safety and side effects were also monitored as secondary outcomes.

Results

The final results posted on ClinicalTrials.gov in June 2015 stated that 11 patients were enrolled and completed the study.

The primary outcome of decreased CYP19 expression with the addition of Celecoxib was not formally tested due to limitations in tissue analysis.

For the secondary outcome of response rate, 7 patients achieved a partial response, 2 had stable disease, and 2 had progressive disease after 16 weeks of Exemestane and Celecoxib treatment.

The combination of Exemestane and Celecoxib was well tolerated. The most common side effects were hot flashes, fatigue, headaches, and muscle aches. There were no serious adverse events reported.

Conclusions

In summary, this small single arm study examined the combination of the aromatase inhibitor Exemestane and the COX-2 inhibitor Celecoxib as a neoadjuvant treatment in 11 postmenopausal women with stage II-IV breast cancer.

The primary outcome of decreased CYP19 expression could not be evaluated due to limitations in tissue analysis.

The combination showed anticancer activity based on the secondary outcome of response rate, with 7 of 11 patients achieving a partial response. The combination was also well tolerated with manageable side effects.

While the study was small and did not include a control group for comparison, the results provide preliminary evidence that combining Exemestane and Celecoxib may be an effective neoadjuvant therapy option for postmenopausal women with breast cancer. Larger randomized trials are needed to confirm these findings.
