Clinical Trial Summary

• 1. There is no standard treatment option for non-clear cell renal cell carcinoma (RCC).

• 2. Patients with non-clear cell RCC is strongly assumed to have benefit from anti-VEGF treatment.

Description:

1. Renal Cell Carcinoma Renal cell carcinoma is a malignant tumor occurring most frequently of primary malignant tumors in kidney.1 According to Korea Central Cancer Registry (KCCR) data, renal cancer affects 4.4 out of 100,000 males and 2.1 out of 100,000 females. About 30% of renal cancer patients accompany remote metastasis at the time of diagnosis and renal cancer even recurs in about 40% of the patients who underwent surgery for radical treatment of renal cancer as a local disease.1 New treatment strategies against renal cell carcinoma have been developed, but they have not obtained satisfactory therapeutic outcomes. Thus, constant clinical studies are necessary to improve therapeutic efficacy.

2. Treatment of Metastatic Renal Cell Carcinoma The treatment for metastatic renal cell carcinoma has been improved a lot for the recent few years, which is, however, limited to clear cell renal cell carcinoma. The drugs showing antitumor activity against clear cell renal cell carcinoma include axitinib, sunitinib, sorafenib, bevacizumab, temsirolimus, and everolimus.

Of them, axitinib, sunitinib, sorafenib, bevacizumab, etc. are neovascularization inhibitors which inhibit vascular endothelial growth factor (VEGF) and its receptor (VEGFR). As a first-line treatment, sunitinib prolongs progression-free survival (PFS) compared to interferon-alpha, being recognized as a first-line standard therapy. Sorafenib, a second-line treatment, shows significant prolongation of PFS against clear cell renal cell carcinoma compared to the placebo control group, establishing itself as a second-line drug. Concomitantly administered with interferon-alpha, bevacizumab shows significant prolongation of PFS compared to the single use of interferon-alpha, establishing itself as another first-line therapy. Temsirolimus, an mammalian target of rapamycin (mTOR) inhibitor, extended survival time in a clinical study of both clear and non-clear cell renal cell carcinoma. However, this clinical study was limited to patients with renal cell carcinoma having bad prognostic factors. This renal cell carcinoma with bad prognostic factors only accounts for 10-20% of entire metastatic renal cell carcinoma. Everolimus, an another mTOR inhibitor, showed a significant prolongation of PFS in the placebo-controlled phase III clinical study of patients with clear cell renal cell carcinoma in whom sunitinib therapy failed, establishing itself as a second-line therapy in case the first-line standard sunitinib therapy fails.

3. Treatment of Metastatic Non-clear Cell Renal Cell Carcinoma (nccRCC) In fact, VEGF antagonists are shown to have some efficacy also in nccRCC. Sunitinib was effective against nccRCC. A worldwide expanded access trial of sunitinib has been undertaken. A subgroup analysis of patients with non-clear-cell histology was performed and 276 patients (11.8%) with non-clear-cell histology were identified, although distinction between different subtypes was not made. A response rate of 5.4%, clinical benefit (defined as response and stable disease was more than 3 months) of 47% and median PFS of 6.7 months was seen in this subgroup. This result compared with an overall response rate for the entire patient group of 9.3%, clinical benefit of 52.3%, and median PFS of 8.9 months. The investigators concluded that sunitinib was active in the non-clear-cell subgroup; however, these data need to be interpreted with caution because of the nonrandomization of patients in the expanded access trial and the lack of pathology verification. Also, recently, phase 2 trial of sunitinib in non-clear cell renal cell carcinoma showed remarkable efficacy with response rate of 36% and median PFS of 6.4 months. The study enrolled non-clear cell RCC patients who did not receive previous anti-angiogenic treatment.

Sorafenib also showed some efficacy in nccRCC, though not so efficacious. The Advanced Renal Cell Carcinoma Sorafenib Expanded Access Program allowed patients in the United States and Canada with metastatic RCC to receive treatment with sorafenib prior to its regulatory approval. This non-randomized, open-label program treated 158 subjects with papillary RCC of a total of 1891 evaluable subjects (81% clear cell, 8% non-clear, and 11% unclassified histology). Of the 107 evaluable subjects with papillary RCC, 90 (84%) had a measurable response to treatment with 3 partial responders and 87 with stable disease for at least 8 weeks, while 17 (16%) subjects demonstrated early progression on treatment. The side effect profile for sorafenib was similar across histologic subtypes, and the authors concluded that sorafenib has some activity in papillary tumors.

On the other hand, in randomized phase 3 trial of single-agent Axitinib in 723 renal cell carcinoma patients who progressed despite first-line therapy containing sunitinib, bevacizumab plus interferon-alpha, temsirolimus or cytokines, the median PFS duration was significantly longer with axitinib than with sorafenib in the entire population (6.7 months versus 4.7 months, respectively: p less than 0.0001).

4. Rationale In short,

1. There is no standard treatment option for non-clear cell RCC.

2. Patients with non-clear cell RCC is strongly assumed to have benefit from anti-VEGF treatment.

3. There is no trial of axitinib for non-clear cell RCC.

4. Axitinib is expected to show more potent efficacy over sorafenib or sunitinib in renal cell carcinoma.

Based on above, this clinical study is designed to examine efficacy and adverse events of axitinib for non-clear cell renal cell carcinoma.
