Special Precautions
Patient with QTc prolongation or significant risk factors for developing QTc prolongation (e.g. electrolyte abnormalities, long QT syndrome; uncontrolled or significant cardiac disease, including recent MI, CHF, unstable angina and bradyarrhythmias). Initiate treatment only in patients with QTcF values <450 milliseconds. Not recommended to be used with tamoxifen. Patients taking concomitant strong CYP3A4 inhibitors. Severe renal and moderate to severe hepatic impairment. Patient Counselling This drug may cause fatigue, dizziness or vertigo, if affected, do not drive or operate machinery. Monitoring Parameters Evaluate pregnancy status (in females of reproductive potential) prior to treatment initiation. Hepatitis B virus screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen is recommended before or at the beginning of systemic anticancer therapy. Obtain CBC and LFTs prior to treatment, every 2 weeks for the 1st 2 cycles, at the start of each subsequent 4 cycles, then as clinically indicated; renal function tests at baseline; serum electrolytes (including K, Mg, Ca, and phosphorus) before treatment, at the beginning of the 1st 6 cycles, and as clinically necessary. Correct electrolyte disturbances prior to therapy initiation. Perform ECG before beginning treatment, repeated on day 14 of the 1st cycle and at the start of the 2nd cycle, then as clinically indicated. Check ECG more frequently if QTcF is prolonged at any time during therapy. Monitor for signs and symptoms of dermatologic toxicity and interstitial lung disease/pneumonitis.

Adverse Reactions
Significant: Bone marrow suppression (e.g. neutropenia, anaemia, lymphopenia, thrombocytopenia), hepatobiliary toxicity (e.g. increased ALT and/or AST), QT prolongation (concentration-dependent).
Blood and lymphatic system disorders: Leucopenia, febrile neutropenia.
Ear and labyrinth disorders: Vertigo.
Eye disorders: Increased lacrimation, dry eye.
Gastrointestinal disorders: Nausea, diarrhoea, vomiting, constipation, stomatitis, abdominal pain, dry mouth, dyspepsia, oropharyngeal pain, gastroenteritis, dysgeusia.
General disorders and administration site conditions: Fatigue, peripheral oedema, asthenia, pyrexia.
Investigations: Abnormal LFTs, increased blood creatinine and gamma-glutamyltransferase.
Metabolism and nutrition disorders: Decreased appetite, hypocalcaemia, hypokalaemia, hypophosphataemia.
Musculoskeletal and connective tissue disorders: Back pain, arthralgia.
Nervous system disorders: Headache, dizziness.
Psychiatric disorders: Insomnia.
Renal and urinary disorders: Urinary tract infection.
Respiratory, thoracic and mediastinal disorders: Dyspnoea, cough, respiratory tract infection.
Skin and subcutaneous tissue disorders: Alopecia, rash, pruritus, erythema, dry skin, vitiligo.
Vascular disorders: Syncope.
Potentially Fatal: Interstitial lung disease, pneumonitis; severe cutaneous adverse reactions (including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms). |
Drug Interactions
Increased risk of QT interval prolongation with tamoxifen, antiarrhythmics (e.g. amiodarone, disopyramide, quinidine, sotalol) and other known QT-prolonging agents (e.g. chloroquine, ciprofloxacin, azithromycin, haloperidol, methadone, moxifloxacin, bepridil, pimozide). May increase ribociclib plasma concentration with strong CYP3A4 inhibitors (e.g. clarithromycin, telithromycin, ketoconazole, itraconazole, ritonavir, indinavir, nefazodone, nelfinavir, telaprevir, verapamil). May decrease plasma concentration and efficacy with CYP3A4 inducers (e.g. phenytoin, rifampicin, carbamazepine). May elevate the serum concentrations of CYP3A4 substrates (e.g. midazolam, alfentanil, fentanyl, ciclosporin, tacrolimus, ergotamine, dihydroergotamine, alfuzosin, cisapride, quetiapine, simvastatin).
