Summary of the safety profile The safety data of panobinostat have been assessed from a total of 451 patients with multiple myeloma treated with panobinostat in combination with bortezomib and dexamethasone and from a total of 278 patients treated with panobinostat as a single agent. The safety data reported below are based on the phase III clinical study (Panorama 1) in 381 patients with multiple myeloma treated with 20 mg panobinostat once a day three times per week, on a 2 weeks on and 1 week off dosing regimen in combination with bortezomib and dexamethasone. The median duration of exposure in the study was 5.0 months. 15.7% of patients were exposed to study treatment for ≥48 weeks. The most common non-haematological adverse reactions were diarrhoea, fatigue, nausea and vomiting. Treatment-emergent haematological toxicities included thrombocytopenia, anaemia, neutropenia and lymphopenia. QTcF >480 and <500 msec was recorded in 1.3% of patients and change from baseline of >60 msec was observed in 0.8% of patients. No patient had an absolute QTcF >500 msec. 13 Cardiac events (most frequently atrial fibrillation, tachycardia, palpitation and sinus tachycardia) were reported in 17.6% of panobinostat + bortezomib + dexamethasone-treated patients versus 9.8% of placebo + bortezomib + dexamethasone-treated patients and syncope events were reported in 6.0% versus 2.4%, respectively. Discontinuation due to adverse events, regardless of causality, was observed in 36.2% of patients. The most common adverse events (AEs) leading to treatment discontinuation were diarrhoea (4.5%), asthenia and fatigue (2.9% each) and pneumonia (1.3%). On-treatment deaths not due to the study indication (multiple myeloma) were reported in 6.8% of panobinostat + bortezomib + dexamethasone-treated patients versus 3.2% of placebo + bortezomib + dexamethasone-treated patients. Tabulated list of adverse drug reactions from clinical studies Adverse drug reactions from the phase III study (Panorama 1) are shown in Table 7. Adverse drug reactions are listed according to system organ classes in MedDRA. Within each system organ class, the adverse drug reactions are ranked by frequency, with the most frequent reactions first. Within each frequency grouping, adverse drug reactions are presented in order of decreasing seriousness. In addition, the corresponding frequency category for each adverse drug reaction is based on the following

Farydak metabolism is through both non-CYP and CYP mediated routes. Approximately 40% of panobinostat is metabolised through CYP3A4. Metabolism via CYP2D6 and 2C19 was minor. Therefore, medicinal products that can influence CYP3A4 enzyme activity may alter the pharmacokinetics of panobinostat. Panobinostat is a P-gp substrate. Agents that may increase panobinostat plasma concentrations Co-administration of a single 20 mg panobinostat dose with ketoconazole, a strong CYP3A inhibitor, increased the Cmax and AUC of panobinostat by 1.6- and 1.8-fold, respectively, compared to when panobinostat was given alone. In patients who take concomitant medicinal products which are strong CYP3A and/or Pgp inhibitors, including, but not limited to, ketoconazole, itraconazole, voriconazole, ritonavir, saquinavir, telithromycin, posaconazole and nefazodone, the dose of panobinostat should be reduced (see section 4.2). Patients should be instructed to avoid star fruit, grapefruit, grapefruit juice, pomegranates and pomegranate juice, as these are known to inhibit cytochrome P450 3A enzymes and may increase the bioavailability of panobinostat. 11 Agents that are predicted to decrease panobinostat concentrations The panobinostat fraction metabolised through CYP3A4 is approximately 40%. In clinical studies in multiple myeloma, the exposure of panobinostat was decreased by approximately 20% by the concomitant use of dexamethasone, which is a dose-dependent mild/moderate CYP3A4 inducer. Strong inducers are expected to have greater effects, and may reduce the efficacy of panobinostat, therefore the concomitant use of strong CYP3A4 inducers including, but not limited to, carbamazepine, phenobarbital, phenytoin, rifabutin, rifampicin and St. John’s Wort (Hypericum perforatum), should be avoided. Agents whose plasma concentrations may be increased by panobinostat Panobinostat increased the Cmax and the AUC of dextromethorphan (a substrate of CYP2D6) by 1.8- and 1.6-fold, respectively, and it cannot be excluded that the effect may be larger on a more sensitive CYP2D6 substrate. Avoid panobinostat use in patients who are taking CYP2D6 substrates with a narrow therapeutic index (including, but not limited to, pimozide). When Farydak is co-administered with sensitive CYP2D6 substrates (e.g. atomoxetine, dextromethorphan, metoprolol, nebivolol, perphenazine and pimozide), dose titrate individual CYP2D6 substrates based on tolerabi

Women of child-bearing potential/Contraception in males and females Based on findings in animals, the likelihood of panobinostat increasing the risk of both foetal death and developmental skeletal abnormalities when administered to pregnant women is predicted to be high. Women of child-bearing potential should have a pregnancy test prior to the initiation of treatment with Farydak and must use a highly effective method of contraception during treatment and for three months after the last dose of Farydak. Women using hormonal contraceptives should additionally use a barrier method of contraception. 12 Due to its cytostatic/cytotoxic mode of action, panobinostat can influence the quality of sperm formed during treatment. Sexually active men taking Farydak and their female partners should use a highly effective method of contraception during the man’s treatment and for six months after his last dose of Farydak. When panobinostat is administered together with dexamethasone, which is known to be a weak to moderate inducer of CYP3A4 as well as other enzymes and transporters, the risk for reduced efficacy of hormonal contraceptives needs to be considered. In addition, it is currently unknown whether panobinostat may reduce the effectiveness of hormonal contraceptives, and therefore women using hormonal contraceptives should additionally use a barrier method of contraception. Pregnancy There are no clinical studies on the use of Farydak in pregnant patients. Studies in animals have shown reproductive and embryo-foetal toxicity (see section 5.3). Given panobinostat’s cytostatic/cytotoxic mode of action, the potential risk to the foetus is high. Farydak should only be used during pregnancy if the expected benefits outweigh the potential risks to the foetus. If it is used during pregnancy or if the patient becomes pregnant while using it, the patient must be informed of the potential risk to the foetus. Breast-feeding It is unknown whether panobinostat is excreted in human milk. Given its cytostatic/cytotoxic mode of action, breast-feeding is contraindicated during Farydak treatment (see section 4.3). Fertility Based on non-clinical findings, male fertility may be compromised by treatment with Farydak (see section 5.3).

Panobinostat is used in combination treatment, therefore the prescribing information of bortezomib and dexamethasone should be consulted prior to initiation of treatment with panobinostat. Decrease in blood cell count Haematological adverse drug reactions, including severe thrombocytopenia, neutropenia and anaemia (CTC grade 3 to 4) were reported in patients treated with panobinostat. Therefore a complete blood count must be performed before initiating therapy with panobinostat, with frequent monitoring during treatment (in particular before each injection of bortezomib as per bortezomib SmPC). The platelet count should be ≥100 x 109/l and the absolute neutrophil count ≥1.0 x 109/l prior to initiation of treatment. Platelet count should be ≥100 x 109/l prior to initiating any cycle of treatment (see section 4.2). In the phase III study, thrombocytopenia typically recovered to baseline by the start of the next 21-day cycle (see Figure 1). The median time to onset for grade 3 and 4 thrombocytopenia was one month and the median time to recovery was 12 days. 8  Figure 1 Median platelet counts over time (Study D2308, Safety set, cycles 1-8) 500 400 Platelets 10 x 109/l 300 200 100 0 (BL) 1:4 1:8 1:11 2:1 2:4 2:8 2:11 3:1 3:4 3:8 3:11 4:1 4:4 4:8 4:11 5:1 5:4 5:8 5:11 6:1 6:4 6:8 6:11 7:1 7:4 7:8 7:11 8:1 8:4 8:8 8:11 PAN+BTZ+Dex PBO+BTZ+Dex Cycle:Day PAN+BTZ+Dex n= 381 370 367 363 351 342 335 320 323 310 298 283 285 265 268 250 253 232 238 225 230 206 206 199 205 183 188 175 185 159 170 155 PBO+BTZ+Dex n= 377 364 368 365 357 349 340 339 335 325 313 302 308 292 292 279 275 255 259 241 251 234 242 203 233 209 217 204 211 192 194 188 PAN=panobinostat BTZ= bortezomib Dex = dexamethasone In patients with CTC grade 3 thrombocytopenia (platelet count <50 x 109/l with bleeding) panobinostat may need to be temporarily withheld and/or the subsequent dose may need to be reduced.
