This study examined the efficacy and safety of canagliflozin in subjects with T2DM and stage 3 CKD, but in a lower, more restricted eGFR range of this classification (i.e. 30 to <50 ml/min/1.73 m rather than to <60 ml/min/1.73 m).
This study included subjects with a lower, more restricted estimated glomerular filtration rate (eGFR) range of ≥30 and <50 ml/min/1.73 m based upon the modification of diet in renal disease (MDRD) equation 12, compared with the typical eGFR range for stage 3 CKD of ≥30 and <60 ml/min/1.73 m.
Patients who test positive will proceed to visit 2 as will patients within 5 mL/min/1.73 m of the upper limit eGFR range of stage 3a CKD (ie, between 60 and 65 mL/min/1.73 m).
Participants within 5 mL/min/1.73 m of the upper limit eGFR range of stage 3a CKD (ie, between 60 and 65 mL/min/1.73 m) will be invited to the second screening visit (visit 2).
This was despite of a similar eGFR range.
We summarized these data by comparing the eGFR range at which one-half of the participants within each study group had these abnormalities and tested for significance of the stratified two-by-two table using the Cochran-Mantel-Haenszel statistic.
Fifty per cent (8/16) of the children achieved significant renal recovery (i.e. eGFR >60 mL/min/1.73 m) and resolution of proteinuria, while another six (37.5%) had an eGFR in the range of 15 60 mL/min/1.73 m on long-term follow-up.
Subsequently, the detection of a fragile site distal to the egfr gene, sustaining uncapped telomere-less chromosomal ends, the ladder-like structure of the intrachromosomal egfr amplification and a broader range of egfr copy numbers support the assumption that dynamic chromosomal rearrangements, like breakage-fusion-bridge-cycles other than proliferation drive the gain of egfr copies.
Among all 175 patients, eGFR ranged from 16 to 168 ml/min/1.73 m, and 102 patients (58%) had an eGFR of less than 60 ml/min/1.73 m.
Gefitinib inhibits EGF-stimulated EGFR autophosphorylation in a broad range of EGFR-expressing human cancer cell lines [ 74].
In the 20 patients that EGFR expression data was collected, we observed a range of EGFR expression and a mixture of homogenous and heterogenous EGFR staining between samples.
