For Healthcare Providers >

Inform The Patient Of The Following:

• Patients should seek immediate medical attention and contact their healthcare provider if they experience symptoms of a severe allergic reaction such as trouble breathing or wheezing; a swollen tongue or throat; a drop in blood pressure resulting in dizziness or fainting; a weak and rapid pulse; hives or widespread itching [seeWarnings and Precautions (5.1)].
• Patients may remove the panels themselves if advised by their healthcare provider to do so or if they are experiencing systemic symptom [seeWarnings and Precautions (5.1)].
• Itching and burning sensations are common with patch testing and may be severe in extremely sensitive patients.
• Avoid UV exposure and tanning beds [seeDosage and Administration (2.1)].
• Patients should report to their physician any reactions at the patch test site occurring seven or more days after panel removal to identify potential late or persistent reactions or possible sensitizations [seeWarnings and Precautions (5.2,5.7,5.8)andDosage and Administration (2.2)].
• p-Phenylenediamine and disperse blue 106 (DB106) are dyes and may leave a dark spot on the skin at the allergen location. This is not an allergic reaction. This discoloration may remain for approximately two weeks.
• Avoid getting the panels and surrounding area wet [seeDosage and Administration (2.1)].
• Patients should avoid physical activity that may result in reduced adhesion or actual loss of the test panels [seeDosage and Administration (2.1)].
• Patients should avoid excessive sweating and keep the test panels and surrounding area dry [seeDosage and Administration (2.1)].

See 17 for PATIENT COUNSELING INFORMATION.

Revised: 8/2017

1 Indications And Usage ⮝

T.R.U.E. TEST is an epicutaneous patch test indicated for use as an aid in the diagnosis of allergic contact dermatitis (ACD) in persons 6 years of age and older whose history suggests sensitivity to one or more of the 35 allergens and allergen mixes included on the T.R.U.E. TEST panels.

2 Dosage And Administration ⮝

2.1 Dose

T.R.U.E. TEST contains three adhesive panels consisting of 35 allergen and allergen mix patches and a negative control. See Description (11) for allergen types and amounts.

2.2 Administration

Application Instructions

T.R.U.E. TEST should only be applied to healthy skin. Test sites should be free of scars, acne, dermatitis, or other conditions that may interfere with test result interpretation. Avoid application of T.R.U.E. TEST panels to recently tanned or sun-exposed skin because this may increase the risk of false negatives. Avoid patch testing on patients for three (3) weeks after ultraviolet (UV) treatments, heavy sun, or tanning bed exposure. Avoid using alcohol or other irritating substances on the skin prior to testing. Avoid excessive sweating during the testing period to maintain sufficient adhesion to the skin. Avoid excessive physical activity to maintain sufficient adhesion and to prevent actual loss of patch test material. Avoid getting the panels and surrounding area wet. If excessive body hair exists at the test site, remove with an electric shaver (do not use razors). Very oily skin may be cleaned with mild soap and water prior to testing.

T.R.U.E. Test panels should be applied as follows:

Figure 1

Figure 2

Figure 3

Figure 4

1. Peel open the package and remove the test panel (Figure 1).

2. Remove the protective plastic covering from the test surface of the panel (Figure 2). Be careful not to touch the test allergens or allergen mixes.

3. Position test Panel 1.3 on the patient's back as shown in Figure 3. Allergen number 1 should be in the upper left corner. Avoid applying the panel on the margin of the scapula or directly over the midline of the spine. Ensure that each patch of the allergen panel is in contact with the skin by smoothing the panel outward from the center to the edge (as illustrated for Panel 3.3 in Figure 3).

4. With a medical marking pen, indicate on the skin the location of the two notches on the panel (as illustrated for Panel 3.3 in Figure 4).

5. Repeat the process with test Panel 2.3. Position the test Panel 2.3 beside Panel 1.3, on the left side of the patient's back so that the number 13 allergen is in the upper left corner. Apply test Panel 2.3 five (5) cm from the midline of the spine (Figure 3).

6. Repeat the process with Panel 3.3 positioning the panel on the right side of the patient's back so that the number 25 allergen is in the upper left corner. Apply test Panel 3.3 five (5) cm from the midline of the spine. (Figure 3)

7. If needed, hypoallergenic surgical tape, appropriate for patch testing, may be used for increased adhesion around the outside edges of the panels.

2.3 Timing of Test Readings

Schedule patients to return approximately 48 hours after patch test application to have the panels removed. Prior to removal of the panels, use a medical marking pen to remark the notches found on the panels. The patch test reaction on the patient's skin may be evaluated at 48 hours, but an additional reading(s) at 72 and/or 96 hours is necessary. Late positive reactions may occur 7 to 21 days after application of the panels. [see Warnings and Precautions (5.2)].

2.4 Interpretation Instructions

An identification template is provided for each of the three (3) panels for quick identification of any allergen that causes a reaction. To assure correct positioning, marks on the skin made with the medical marking pen should correlate with the notches on the template. The interpretation method, similar to the one recommended by the International Contact Dermatitis Research Group, is as follows:

	?	Doubtful reaction: faint macular erythema only
	+	Weak positive reaction: non-vesicular with erythema, infiltration, possibly papules
	++	Strong positive reaction: vesicular, erythema, infiltration, papules
	+++	Extreme positive reaction: bullous or ulcerative reaction
	-	Negative reaction
	IR	Irritant reaction: Pustules as well as patchy follicular or homogeneous erythema without infiltrations are usually signs of irritation and do not indicate allergy.

Itching is a subjective symptom that is expected to accompany a positive reaction.

False Negatives

False negative results may be due to insufficient patch contact with the skin and/or premature evaluation of the test. Repeat testing may be indicated. The effect of repetitive testing with T.R.U.E. TEST is unknown [see Warnings and Precautions (5.9)].

False Positives

A false positive result may occur when an irritant reaction cannot be differentiated from an allergic reaction. A positive test reaction should meet the criteria for an allergic reaction. If an irritant reaction cannot be distinguished from a true positive reaction or if a doubtful reaction is present, a retest may be considered. The effect of repetitive testing with T.R.U.E. TEST is unknown [see Warnings and Precautions (5.9)].

3 Dosage Forms And Strengths ⮝

T.R.U.E. TEST contains three (3) adhesive panels consisting of 35 allergen and allergen mix patches and a negative control. Panel 1.3 contains 11 allergens and allergen mixes and a negative control. Panel 2.3 contains 12 allergens and allergen mixes. Panel 3.3 contains 12 allergens and allergen mixes. See Description (11) for allergen types and amounts.

4 Contraindications ⮝

Do not apply to skin of patients with a history of severe allergic reaction (systemic and/or local) to any of the allergen components or inactive substances of T.R.U.E. TEST [see Description (11)].

Do not apply to skin that is injured or inflamed.

5 Warnings And Precautions ⮝

5.1 Acute Allergic Reactions

Acute allergic reactions, including anaphylaxis, may occur following the application of T.R.U.E. TEST. If a severe allergic reaction occurs, remove the T.R.U.E. TEST panel(s) and initiate appropriate medical treatment. Immediate contact urticaria may present within minutes to an hour after application in patients who are pre-sensitized to some allergens and may be local or generalized. Patients may be advised to remove the panels themselves if they experience systemic symptoms [see Patient Counseling Information (17)].

5.2 Sensitization

A negative patch test reaction, followed by a positive reaction 10 to 20 days after panel application, may indicate active sensitization. Active sensitization is confirmed upon retesting with a positive reaction occurring at the 72 and/or the 96 hour reading. If patients undergo a second series of patch tests immediately, select a new test site for T.R.U.E. TEST application. Alternatively, the same site may be retested after a 3-week clearing period, provided the site remains free of conditions that might affect test results [see Dosage and Administration (2.1)]. The safety and effectiveness of repetitive testing with T.R.U.E. TEST is unknown [see Warnings and Precautions (5.9)].

5.3 Extreme Positive Reactions

Extreme positive (+++) reactions that are bullous or ulcerative with pronounced erythema, infiltration, and coalescing vesicles may present in extremely sensitive patients [see Dosage and Administration (2.3)].

5.4 Excited Skin Syndrome (Angry Back)

Excited skin syndrome is a regional state of skin hyper-reactivity caused by the presence of a strong positive reaction which may result in other patch test sites to become reactive.

5.5 Tape Reactions

Reactions to the T.R.U.E. TEST tape or adhesive may occur. T.R.U.E. TEST panel tape and the individual patches are composed of polyester. The adhesive used in the panels is acrylate-based and processed to remove free monomers that may be allergenic [see Description (11)].

5.6 Irritant Contact Dermatitis

Patients may experience irritant contact dermatitis upon exposure to any of the allergens contained within T.R.U.E. TEST that cause direct damage to the skin at the test site. Recurrence of an irritant response is not limited to exposure to the specific allergens or allergen mixes, but may follow exposure to any chemical irritants.

5.7 Persistent Reactions

Positive reactions may persist from 7 days to months after panel application.

5.8 Late Reactions

Positive reactions may occur 7 to 21 days after application of the panels.

5.9 Repeat Testing

The safety and efficacy of repetitive testing with T.R.U.E. TEST is unknown. Sensitization or increased reactivity to one or more of the allergens may occur [see Warnings and Precautions (5.2)]. If patients undergo a second series of patch tests immediately, select a new test site for T.R.U.E. TEST application. Alternatively, the same site may be retested after a 3-week clearing period, provided the site remains free of conditions that might affect test results. [see Dosage and Administration (2.1)].

6 Adverse Reactions ⮝

In adults 18 years of age and older, the most common (occurring in >1% of the study population) adverse reactions were burning (25.4%), tape irritation (15.8%), persistent reactions (6.8%), erythema (5.7%), and hyper/hypopigmentation (4.9%). In children and adolescents 6 through 17 years of age, the most common (occurring in >1% of the study population) adverse reactions were itching (up to 61.2%), tape irritation (up to 50.0%), persistent reactions (4.6%), ectopic flare of pre-existing dermatitis (12.8%), burning (up to 10.5%), skin infections (1.8%), and skin reactions near a panel site (1.4%).

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug may not reflect the rates observed in clinical practice.

Panel Adhesion: Problems with panel adhesion were observed during some of the clinical studies. Poor panel adhesion was defined as any panel that fell off prior to the 48-hour removal time, any test panel that was not in good contact with the skin, or if one or more of the patch test allergens were not in good contact with the skin as evidenced at the time of panel removal, 48 hours. If the panel fell off the back prior to the 48-hour removal time frame, the subject was excluded from the efficacy calculations (sensitivity and specificity) but not from the safety analysis. Over all studies, poor panel adhesion occurred 49 times (4.2%) (Table 3). In study 2, the poor adhesion was attributed to the particular lot of adhesive used to manufacture the clinical test tape.

Children and Adolescents 6 through 17 Years of Age

The safety of T.R.U.E. TEST in children and adolescents 6 through 17 years of age was evaluated in two open-label studies conducted in the US. In these studies, children and adolescents with suspected allergic contact dermatitis had three T.R.U.E. TEST panels applied to their backs and upper arms by investigators. Some of the panels were from previously approved versions of T.R.U.E. TEST. Subjects were instructed to keep the panels in place for 48 hours. Subjects were monitored for safety for 21 days after application of T.R.U.E. TEST panels. The safety monitoring plan included investigator's assessment of panel adhesion, tape irritation, and participant reporting of burning and itching (as a combined symptom) when panels were removed 2 days after application of T.R.U.E. TEST. Surveillance for late reactions, possible sensitization and persistent reactions occurred at Day 7 and 21. Unsolicited adverse events, serious adverse events and deaths were monitored for 21 days after patch application.

Pediatric Study 1 (NCT: 00795951)

In this prospective, single-center, open label study, 102 subjects were enrolled to evaluate the safety of T.R.U.E. TEST [see Clinical Studies (14.2) Table 7 for a list of the allergens and allergen mixes]. Of enrolled subjects, 52% were female, 39.2% were White, 31.4% were Hispanic, 6.9% were Black, 12.7% were Asian and 10.5% were of other racial/ethnic groups. The mean age of subjects was 11.6 years.

Pediatric Study 2 (NCT: 01797562)

In a prospective, multi-center, open-label study conducted in the US, up to 116 children and adolescents were enrolled to evaluate the safety of T.R.U.E. TEST [see Clinical Studies (14.2) Table 7 for a list of the allergens and allergen mixes]. Of enrolled subjects, 69% were female, 37.9% were Hispanic or Latino, 28.5% were White, 11.2% were Asian, 6.0% were Black, and 16.4% were of other racial/ethnic groups. The mean age of subjects was 12.6 years. Table 4 summarizes adverse reactions occurring within 21 days after T.R.U.E. TEST application.

* NCT: 01797562 Fifty five subjects received Panel 1.3 and 61 subjects received Panel 1.2, which included 4 allergens with outdated formulations. Fifty four of the 55 subjects presented on day 2 as scheduled. Of the 116 subjects who received T.R.U.E. TEST, 114 presented to visit 2 and had itching, burning, and tape irritation data documented. Itching and burning were graded as none, mild/weak (minimal discomfort), moderate (definite discomfort), or severe (significantly bothersome, possible interference with sleep or daily activity). Tape irritation was graded at Day 2 by investigators using a 4-point scale, including none, weak (faint to definite pink erythema), moderate (moderate erythema, definite redness), or severe (severe erythema, very intense redness).
Itching	31 (57.4)	62 (54.4)	72 (63.2)	1 (1.9)	7 (6.1)	11 (9.7)

Tape irritation	27 (50.0)	56 (49.1)	53 (46.5)	0 (0.0)	1 (0.9)	0 (0.0)

Across both pediatric studies (N=218), extreme positive reactions (+++, indicating a bullous or ulcerative reaction with pronounced erythema, infiltration, and coalescing vesicles) occurred in two subjects. Both extreme positive reactions occurred in response to metal allergens (nickel sulfate and gold sodium thiosulfate) by Day 3 and resolved by Day 21. Late positive reactions occurred in 2 subjects (0.9%) 21 days after T.R.U.E. TEST application to the following allergen: gold sodium thiosulfate (n=2). Persistent reactions occurred in 10 subjects (4.6%) 21 days after T.R.U.E.

Skin reactions near a panel site were observed in 3 subjects (1.4%). No serious adverse events or deaths considered related to T.R.U.E. TEST occurred.

Panel Adhesion

In Pediatric Study 2, poor panel adhesion was observed in up to 11.3% of subjects who received T.R.U.E. TEST panels. Panel(s) fell off in up to 3.6% of participants in Pediatric Study 2.

6.2 Postmarketing Experience

The following additional adverse reactions have been identified during post-approval use of T.R.U.E. TEST. Because these reactions are continuously reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to T.R.U.E. TEST exposure.

• Acute allergic reactions [see Warnings and Precautions (5.1)]
• Extreme positive reactions [see Warnings and Precautions (5.3)]
• Excited skin syndrome (Angry back) [see Warnings and Precautions (5.4)]
• Irritant contact dermatitis [see Warnings and Precautions (5.6)]

12 Clinical Pharmacology ⮝

12.1 Mechanism of Action

A positive response to the patch test is a classic delayed cell-mediated hypersensitivity reaction (type IV), which normally appears within 9 to 96 hours after exposure. Following primary contact, an allergen penetrates the skin and binds covalently or noncovalently to epidermal Langerhans cells. The processed allergen is presented to helper T-lymphocytes, resulting in inflammation that produces a papular, vesicular, or bullous response with erythema and itching at the site of application.

14 Clinical Studies ⮝

A basic description of the interpretation method used by study personnel to evaluate the patch reactions obtained during the clinical studies is as follows [see Dosage and Administration (2)]:

	?	Doubtful reaction
	+	Weak positive reaction
	++	Strong positive reaction
	+++	Extreme positive reaction
	-	Negative reaction
	IR	Irritant reaction

14.1 Adults

Ten (10) studies were conducted in North America and Europe to evaluate the effectiveness, frequency of patch reactions, and/or sensitivity and specificity, and/or agreement with a reference allergen (when used) of T.R.U.E. TEST used to diagnosis allergic reactions to one or more allergens and or allergen mixes in the panels in adults. Subjects ranged in age from 18 through 86 years. Subjects with suspected allergic contact dermatitis, based on history or clinical signs, were tested in all studies. The allergens tested in each of the studies are noted in Table 1 [see Adverse Reactions (6.1)].

Study No. 1

This study evaluated the efficacy of T.R.U.E. TEST Panel 1.1. A total of 127 subjects with suspected contact dermatitis were recruited. T.R.U.E. TEST Panel 1.1, containing 12 allergens (no negative control was on the original Panel 1) was applied to the subject's back and remained there for 48 hours. The results were evaluated after 48 and 72 to 96 hours. Forty-five (45) subjects showed a total of 65 reactions to 11 of the 12 allergens in Panel 1.1. There were positive test reactions to all allergens except potassium dichromate. See Table 4.

This study evaluated the sensitivity and specificity of T.R.U.E. TEST Panel 3 allergens tixocortol-21-pivalate (TIX) and budesonide (BUD) for diagnosing allergic contact dermatitis in a North American patient population. Comparison of allergen reactivity between allergens in T.R.U.E. TEST and allergens in petrolatum were made. One hundred twenty-eight (128) subjects were enrolled and included 100 consecutive subjects (subjects with a clinical history consistent with allergic contact dermatitis without a previous positive patch test reaction) and sensitive subjects with a previous positive patch test reaction to petrolatum based TIX (9 subjects) and BUD (19 subjects) allergens in the past 5 years and clinical history of allergic contact dermatitis. T.R.U.E. TEST Panel 3 allergens TIX and BUD were applied to the subject's back and remained there for 48 hours. Patch test reactions were evaluated 72 to 96 hours and again 7 days after application for 94 subjects. Six (6) subjects were withdrawn at Visit 2 due to poor tape adhesion prior to Visit 2. Patch test reactions were evaluated using the study endpoints, including measurements of positive reaction frequency, specificity, sensitivity, and agreement estimate as shown in Table 4.

Study No. 7

This study evaluated the sensitivity and specificity of T.R.U.E. TEST Panel 3.1 allergens tixocortol-21-pivalate (TIX), Hydrocortisone-17-butyrate (H-17-B), and budesonide (BUD) for diagnosing allergic contact dermatitis in a European patient population. Comparison of allergen reactivity between allergens in T.R.U.E. TEST and allergens in petrolatum were made. The enrolled study population included 200 consecutive subjects (subjects with a clinical history consistent with allergic contact dermatitis without a previous positive patch test reaction). T.R.U.E. TEST allergens TIX, H-17-B, BUD, and the corresponding petrolatum reference allergens were applied to the subject's back and remained there for 48 hours. Patch test reactions were evaluated at 72 to 96 hours and again 7 days after application. Of the 200 consecutive subjects evaluated, 1 subject was withdrawn due to poor tape adhesion prior to Visit 2 and 1 subject was excluded due to no follow-up visits. Therefore, 198 subjects were included in the evaluation of TIX and BUD. In addition, 3 subjects were withdrawn due to the H-17-B reference allergen patch not being applied at the initial visit. Therefore, 195 subjects were included in the evaluation for H-17-B. Patch test reactions were evaluated using the study endpoints, including measurements of positive reaction frequency, specificity, sensitivity, and agreement estimate as shown in Table 4.

Study No. 8

This was an open label, prospective, multi-center (5 site) study that evaluated the sensitivity and specificity of gold sodium thiosulphate (GST), Hydrocortisone-17-butyrate (H-17-B), bacitracin, parthenolide, methyldibromo glutaronitrile (MDBGN), disperse blue 106 (DB106), and 2-bromo-2-nitropropane-1,3-diol (bronopol) in adult subjects with suspected contact dermatitis and in adult subjects with a known or suspected sensitization to at least 1 of the 7 allergens. Of the 235 enrolled subjects, 110 were consecutive subjects (subjects with a clinical history consistent with allergic contact dermatitis without a previous positive patch test reaction) and 125 were sensitive subjects (subjects with a previous positive patch test reaction to at least 1 of the 7 allergens). The frequencies of all patch test reactions for each allergen were tabulated at 72 to 96 hours.

The agreement between the T.R.U.E. TEST allergens and their corresponding reference allergens was generally high among subjects who were sensitive to each allergen as seen in Table 4. With the exception of MDBGN, subjects who had sensitivities to each individual allergen had similar reactions to both the T.R.U.E. TEST allergens and the corresponding reference allergens with percent agreements ranging from 75.0% (for bacitracin) to 94.4% (for parthenolide). The results for MDBGN in this study may be unreliable due to the presence of phenoxyethanol (PE) in the reference allergen. Specifically, PE is a recognized irritant. Results of frequency, specificity, sensitivity, and agreement estimate are shown in Table 4.

Study No. 9

This in-use study evaluated the relationship between reactions caused by a natural sensitizer, such as nickel containing costume jewelry, and T.R.U.E. TEST. Forty nine (49) subjects with a history of cutaneous reactions to jewelry were tested with T.R.U.E. TEST Panel 1.1. A medallion containing approximately 20% nickel served as a positive control. Reactions were evaluated 72 to 96 hours after application. In comparing the in-use test results, 35% of the T.R.U.E. TEST nickel patch positive results would have been considered false positives and 5.3% would have been considered false negatives. However, the results from this study may be unreliable. The metal composition of jewelry can vary greatly from manufacturer to manufacturer and thereby alter the bioavailability of the nickel ions. A different medallion could have produced either a greater or lesser correlation with T.R.U.E. TEST nickel patch. The comparatively large number of additional nickel positive results obtained with T.R.U.E. TEST may be true positives unresponsive to the particular medallion used in this study, although false positive reactions cannot be ruled out.

Study No. 10

The study was a Phase 4 postmarketing open label, non-randomized, non-blinded prospective study including nine subjects. All subjects had previous positive patch test results for Quaternium-15 (Q-15). The subjects were exposed to the T.R.U.E. TEST Q-15 patch at a concentration of 100 mcg/cm2 and daily applications of a topical product containing Q-15 after the completion of the patch test. Reactions were evaluated 72 to 96 hours after application. T.R.U.E. TEST detected Q-15 sensitivity in 87.50% (7/8) of the Q-15 allergic subjects while the topically applied lotion elicited a positive response in 50% (4/8) of the study population. One subject tested negative to both methods of Q-15 and was removed from the endpoint analysis.

Study Data

Table 4 presents the frequency of positive reactions to T.R.U.E. TEST in consecutive subjects (subjects with a clinical history consistent with allergic contact dermatitis without a previous positive patch test reaction) for each allergen. The frequency of positive reactions to T.R.U.E. TEST in consecutive subjects and sensitive subjects (subjects with a previous positive patch test reaction to a specific allergen or allergens) for Quaternium-15 are presented in Table 4. The sensitivity, specificity, and agreement estimate between each T.R.U.E. TEST allergen and the corresponding reference allergen (when used) are presented for consecutive subjects and sensitive subjects (when done) in Table 4.

Sensitivity was determined using the formula [TP / (TP + FN)] 100, where TP (true positive) represented positive results for both the T.R.U.E. TEST allergen and the corresponding reference allergen, and FN (false negative) represented negative results for the T.R.U.E. TEST allergen and positive results for the corresponding reference allergen. Specificity was determined using the formula [TN / (TN + FP)] 100, where TN (true negative) represented negative results for both the T.R.U.E. TEST allergen and the corresponding reference allergen, and FP (false positive) represented positive results for the T.R.U.E. TEST allergen and negative results for the corresponding reference allergen. The agreement estimate (with 95% confidence intervals), as well as overall percent agreement and Cohen's kappa statistic between the test site skin reactions obtained for each of the seven T.R.U.E. TEST Panel 3.2 allergens and the test site skin reactions obtained for their associated reference allergens in petrolatum or ethanol were calculated for all subjects combined, as well as for the populations of sensitive and consecutive subjects.

14.2 Children and Adolescents 6 through 17 Years of Age

Two studies were conducted in the US to evaluate the diagnostic performance of T.R.U.E. TEST in children and adolescents 6 through 17 years of age. Subjects had three T.R.U.E. TEST panels applied to their back or upper arm for 48 hours. Reactions at the patch test sites were evaluated at days 3 and/or 4, 7 and 21 after patch test application [see Interpretation Instructions (2.4)].

Pediatric Study 1

In an open-label, prospective, single-center study conducted in the US, 102 children and adolescents 6 through 17 years of age with suspected allergic contact dermatitis were enrolled to evaluate the diagnostic performance of a previously approved version of T.R.U.E. TEST (Panels 1.1, 2.1, 3.1). This version included a negative control and 28 allergens and allergen mixes, 4 (on Panel 1.1) of which were reformulated and are not included on Panel 1.3. The per-protocol analysis set included 100 subjects. The frequencies of positive reactions to the 24 allergens contained in T.R.U.E. TEST and to the negative controls are shown in Table 7.

Pediatric Study 2

In an open-label, prospective, multi-center study conducted in the US, 116 children and adolescents 6 through 17 years of age with suspected allergic contact dermatitis were enrolled. Although the three T.R.U.E. TEST panels administered to subjects in this study included all 35 allergens and allergen mixes, the primary analysis of diagnostic performance was limited to the 4 reformulations and the 7 new allergens and allergen mixes. The frequencies of positive reactions to 11 of the allergens contained in T.R.U.E. TEST and to the negative control were analyzed and are shown in Table 7.

Table 7- Pediatric Studies 1*and 2 : Frequencies of Positive Reactions (on Days 3, 4, and 7 After T.R.U.E. TEST Application) to T.R.U.E. TEST Allergens Among Children and Adolescents 6 through 17 Years of Age with Suspected Allergic Contact Dermatitis: Per Protocol Analysis Sets

		Pediatric Study 1*	Pediatric Study 2
* NCT: 00795951 NCT: 01797562 In Pediatric Studies 1 and 2, positive patch reactions were read on days 3, 4, and 7. Frequencies of positive reactions reported in this table include those characterized as weak (+), strong (++), and extreme positive (+++) based on presence and degree of erythema, infiltration, papules, vesicles, and bullae. Only 53 subjects in Pediatric Study 2 in the per-protocol analysis set received Panel 1.3. NA= Not Applicable/Not Available.The results are not applicable because the allergens and allergen mixes were either from previously approved formulations, not evaluated or not pre-specified as the primary endpoint of the study.
