LUMISIGHT

WARNING: ANAPHYLAXIS AND OTHER SERIOUS HYPERSENSITIVITY REACTIONS Serious hypersensitivity reactions, including anaphylaxis, can occur during or following administration of LUMISIGHT. Anaphylaxis occurred in 4/726 (0.6%) of patients in clinical studies. Signs and symptoms associated with other hypersensitivity reactions included pruritus, urticaria, hypotension, lip swelling, erythema, anxiety, chest pain, cyanosis, dizziness, dyspnea, headache, hypoesthesia, hyperventilation, maculopapular rash, nausea, paresthesia, visual changes, and vomiting. Before LUMISIGHT administration, assess all patients for any history of hypersensitivity reaction to contrast media or products containing polyethylene glycol (PEG). Always have emergency resuscitation drugs, equipment, and trained personnel promptly available. Monitor all patients for hypersensitivity reactions. If a hypersensitivity reaction is suspected, immediately discontinue the injection and initiate appropriate therapy. LUMISIGHT is contraindicated in patients with a history of hypersensitivity reactions to pegulicianine [see Warning and Precautions (5.1) ] . WARNING: ANAPHYLAXIS AND OTHER SERIOUS HYPERSENSITIVITY REACTIONS See full prescribing information for complete boxed warning. Serious hypersensitivity reactions, including anaphylaxis, can occur during or following administration. Anaphylaxis has occurred in 4/726 (0.6%) of patients in clinical studies. Before LUMISIGHT administration, assess all patients for any history of hypersensitivity reaction to contrast media or products containing polyethylene glycol (PEG). Always have emergency resuscitation drugs, equipment, and trained personnel available. Monitor all patients for hypersensitivity reactions. If a hypersensitivity reaction is suspected, immediately discontinue the injection and initiate appropriate therapy. ( 5.1 ).

5 WARNINGS AND PRECAUTIONS Risk of Misdiagnosis : Absence of signal in the surgical field does not rule out the presence of cancer. Positive signal may be seen in non-cancerous tissue. ( 5.2 ) Interference from Dyes Used for Sentinel Lymph Node Mapping : Avoid administration of dyes before imaging the lumpectomy cavity in patients receiving LUMISIGHT. ( 5.3 , 7 ) 5.1 Anaphylaxis and Other Serious Hypersensitivity Reactions Prepare for the possibility of drug hypersensitivity reactions (including anaphylaxis), which can occur during or following administration, and take the necessary precautions. In clinical studies, 4 of 726 (0.6%) patients treated with LUMISIGHT experienced signs and symptoms consistent with anaphylaxis. The onset was during administration in three patients. Signs and symptoms associated with other hypersensitivity reactions included pruritus, urticaria, hypotension, lip swelling, erythema, anxiety, chest pain, cyanosis, dizziness, dyspnea, headache, hypoesthesia, hyperventilation, maculopapular rash, nausea, paresthesia, visual changes, and vomiting [see Adverse Reactions ( 6.1 )]. Before LUMISIGHT administration, assess all patients for any history of hypersensitivity reaction to contrast media or products containing polyethylene glycol (PEG), as these patients may have an increased risk for hypersensitivity reaction to LUMISIGHT. In clinical studies, three out of four patients that experienced anaphylaxis did not have a history of hypersensitivity reaction to contrast media or products containing PEG. Always have emergency resuscitation drugs, equipment, and trained personnel available. Monitor all patients for hypersensitivity reactions through symptom reporting, direct observation, and vital sign measurements. If a hypersensitivity reaction is suspected, immediately discontinue the injection and initiate appropriate therapy. LUMISIGHT is contraindicated in patients with a history of hypersensitivity reaction to pegulicianine [see Contraindications ( 4 )] . 5.2 Risk of Misdiagnosis False positive and false negative findings may occur during use of LUMISIGHT to detect residual cancer. Absence of signal in the lumpectomy cavity does not rule out the presence of residual cancer. Additionally, positive signal has been observed in some non-cancerous tissue [see Clinical Studies ( 14 )]. 5.3 Interference from Dyes Used for Sentinel Lymph Node Mapping Blue dyes used for sentinel lymph node (SLN) mapping procedures interfere with LUMISIGHT imaging. The potential of other dyes to interfere with LUMISIGHT imaging has not been evaluated. Avoid administration of dyes used for SLN mapping procedures before imaging the lumpectomy cavity in patients receiving LUMISIGHT [see Drug Interactions ( 7 )].

6 ADVERSE REACTIONS The following clinically important adverse reactions are described elsewhere in the labeling: Anaphylaxis and Other Serious Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] Most common adverse reactions (≥1%) were hypersensitivity and chromaturia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Lumicell at 1-833-458-6387 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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 cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of LUMISIGHT was evaluated in 726 patients who received a single dose of 1 mg/kg of LUMISIGHT. Among these 726 patients, 703 (97%) had breast cancer and 23 (3%) had other types of cancer. The mean age of the patients was 62 years (range: 36 years to 95 years), and 98% of them were female. Distribution by race was 82% White, 7% Black or African American, 6% Asian, and 5% other or unreported. Distribution by ethnicity was 3% Hispanic/Latino, 93% non-Hispanic/Latino, and 4% unknown or unreported. Adverse reactions occurring in ≥ 1% of patients receiving LUMISIGHT were hypersensitivity (1.4%, including anaphylaxis [4 out of 726]) and chromaturia (85%). Chromaturia resolved within 48 hours after administration in 93% of patients, with the longest time to resolution of 15 days. Adverse reactions occurring in use < 1% of patients were skin discoloration after extravasation, nausea, dyspnea, pyrexia, and vomiting.
