SUMMARY - CONCLUSION
EFFICACY RESULTS:
It can be seen that in both treatment groups (Phlogenzym® + antibiotics
vs. placebo + antiobitics) the sumscores decreased considerably from
a similar baseline level (data set: ITT):
| Phlogenzym® : |
8.8 (SD: 3.41) on day 1 |
-> |
1.4 (SD: 1.79) on day 7 |
| placebo: |
9.2 (SD: 2.77) on day 1 |
-> |
2.2 (SD: 2.10) on day 7 |
The Phlogenzym® treatment group attained a larger change from baseline
(day 1 minus day 7) than the placebo group (data set: ITT):
| Phlogenzym® : |
7.4 (SD: 3.83) |
| placebo: |
6.8 (SD: 3.89) |
General results
The one-sided Wilcoxon-Mann-Whitney-U-test of the sum-score on day 7
(change from baseline) gave no hints for group differences (P = 0.2101
), a small trend to superiority of Phlogenzym® (MW = 0.5440; Cl95%:
0.4382 to 0.6498) was found, however, for the ITT data set. The second
primary criterion of the protocol, time-to-freedom of 3 complaints,
resulted in a "significant" P = 0.0030 (Peto-Wilcoxon). A new analysis
with the appropriate percentage change values of index values resulted
in a definite hint for superiority of the test drug. The Wilcoxon results
were P1-sided = 0.0096 and MW = 0.6253 (Cl95%:
0.5223 to 0.7283).
The results of the centers were inconsistent (data set: ITT): Lücke
(inferiority); Schult, Gebauer, and Timpe (superiority of Phlogenzym®)
Ahn (inferiority: sum-score; superiority: time-to-freedom).
Subgroup analysis
A stratified analysis was run with two strata with range [0 to 7] and
[8 and more] of the baseline sum-scores. For index-values on day 7 there
is a good benefit resulting from the test preparation for patients with
scores 0 to 7 (sum-score: P = 0.0071, OR = 1.7542); for patients with
higher baseline values there is little effect (sum-score: P = 0.1761,
OR = 1.2413). For time-to-freedom of complaints, there is, however,
a definite advantage in both strata (range 0-7: P = 0.0283, OR = 2.4677;
range 8 to 15: P = 0.0190, OR = 1.9320), whatever the baseline.
SAFETY RESULTS:
During the 14 days observation period 5 adverse events were reported
in 4/58 (6.9%%) Phlogenzym®-patients and 14 adverse events in 9/58 (15.5%)
placebo-patients. No serious adverse event occurred. The tolerability
was rated by the investigator as "very good" or "good" for 50/54 (92.6%)
Phlogenzym® -patients and for 45/50 (90.0%) placebo-patients.
Phlogenzym® was well tolerated according to the ratings of the investigator
and the patients.
CONCLUSION:
Phlogenzym® plus antibiotics had a "medium" superiority in comparison
with placebo plus antibiotics in patients with acute cystitis. Phlogenzym®
was well tolerated.
