The efficacy and safety of AMELUZ in combination with PDT using a narrow spectrum (red light lamp) source were evaluated in three randomized, multicenter trials (Trials 1, 2, and 3). Trials 2 and 3 were vehicle-controlled and double-blind. Trial 1 was double-blind with respect to vehicle and observer-blind regarding the active comparator arm. All clinical trials included a follow-up assessment after 6 and 12 months.

In these trials, 212 subjects with 4 to 8 mild to moderate AK lesions on the face/forehead and/or bald scalp were treated with up to one tube (2 grams) of AMELUZ on an application area up to 20 cm² and a narrow band spectrum lamp. Subjects ranged from 49 to 87 years of age (mean 71 years), and 92% had Fitzpatrick skin type I, II, or III. No subjects had Fitzpatrick skin type V or VI. Approximately 86% of subjects were male, and all subjects were White.

All sessions were comprised of lesion preparation to roughen the surface and remove crusts, application of AMELUZ with occlusion for 3 hours, and removal of the residual gel. Subsequently, the entire treatment area was illuminated with a narrow spectrum red light source, a lamp of either 630 nm or 633 nm and a light dose of approximately 37 J/cm2. In Trial 3, illumination was performed with BF-RhodoLED, a red light source with a narrow spectrum around 635 nm and a light dose of approximately 37 J/cm2.

In all trials, the lesions that were not completely cleared 12 weeks after the initial treatment were treated a second time with an identical regimen. In the trials, 42% (88/212) of subjects needed a second treatment.

The primary endpoint for all trials was complete clearance 12 weeks after the last PDT. The results of Trials 1, 2 and 3 are presented in Table 2.

Subjects who achieved complete clearance at 12 weeks after the last PDT entered a 12-month follow-up period. In the three trials, subjects who received AMELUZ with the narrowband PDT and achieved complete clearance 12 weeks after the last PDT had recurrence rates of 14%, 11%, and 25%, respectively (at 6 months) and 40%, 22%, and 37%, respectively (at 12 months).

Recurrence was defined as the percentage of subjects with at least one recurrent lesion during the 6-month or 12-month follow-up period in subjects with completely cleared lesions 12 weeks after the last PDT.

8.4.4 The Treatment Profile

The RhodoLED® XL has a fixed LED light intensity which ensures the application of 37 J/cm² within the 13.5-minute treatment time.

8.4.5 Selecting Active LED Panels

The device has 5 LED panels which are also displayed by the software (Figure 10). The illustrated panels are visible from the back side and the corresponding panel of the device can be identified via the handles, starting from the left. All panels are activated by default and can be deactivated via the software. To deactivate LED panels, press on the illustrated panel. For easier orientation, the panel number can also be found at the backside of the respective panel (Figure 11).

Figure 10: Software illustration of RhodoLED® XL LED panels (all panels are activated)

Figure 11: Panel number at the backside of the panel

Deactivated panels are displayed in grey with a power symbol in their centers (Figure 12). Activated panels are highlighted and the current distance to the treatment area is displayed.

Figure 12: Coloring of a switched off panel

8.4.6 Treatment Area

The illumination area of RhodoLED® XL is 9.06 x 11.42 inch (23 cm x 29 cm) when all panels are arranged in the standard curved shape. This usually allows a full-face illumination. However, face and head sizes are subject to strong variations between patients. As a rough guidance, the midlines of the outer two panels marks the outer boundaries of the illumination area (see Figure 13 as guidance).

Note: The RhodoLED® XL LED panels should only be used in curved shape and not in fully unfolded form. This is necessary to ensure the application of 37 J/cm² during the illumination.

Figure 13: Treatment area of RhodoLED® XL from the side and in top view.

Note: If less than 5 panels are used for a treatment, it must be ensured that at least three adjacent panels are used. The treatment area is thereby reduced and reaches from the midline of the one outer panel to the other midline of the other outer panel.

If a treatment with less than 5 active LED panels is started, a message dialog appears which must be confirmed.

8.4.7 Adjusting the Treatment Distance

The correct treatment distance for the RhodoLED® XL is 4.9 ± 0.6 inch (12.5 ± 1.5 cm). Each LED panel is equipped with a distance sensor to allow individual adjustment of all panels. The distance sensor is automatically switched on if the panel is switched on. The current distance of each panel is shown on the control unit display above the panel illustration. The following table summarizes the visualization of the treatment distance.

Note: When starting the treatment, the LED panels that are too close or too far away from the treatment area will nevertheless also light up. To disable an LED panel during the treatment it must be switched off on the display (see Figure 12).

Table 1: Adjusting the treatment distance

8.4.8 Adjustment Light

If the correct treatment distance of 4.9 inch (12.5 cm) is set the LEDs of the panel light up at a low light intensity to allow an easy adjustment of the distance and the target treatment area.

The size of the treatment area is 9.06 x 11.42 inch (23 cm x 29 cm) for all panels in a curved shape.

Note: When starting the treatment, the LED panels that are too close or too far away from the treatment area will nevertheless also light up. To disable an LED panel during the treatment it must be switched off on the display (see Figure 12).

Figure 14: Low light intensity for correct adjustment of LED panels.

8.4.9 Starting an Illumination

To start a treatment, press the Start button. Before starting the treatment make sure every person present wears the correct eye protection (see chapter 6) and confirm the query for eye protection (Figure 15).

Figure 15: Note on eye protection before starting treatment.

During the illumination, the remaining treatment time is displayed in the diagram. The progress is marked green in the profile and with a green dotted vertical line (Figure 16).
