Exclusion Criteria

Patients with any of the following at Visit 1, Visit 2, Visit 3, or Visit 4 (unless otherwise stated) will be excluded from participation in the study. 1. Patients previously treated in an aliskiren study that contained the treatment group of the combination of aliskiren and amlodipine and had been randomized or enrolled into the active drug treatment period of that study. 2. Severe hypertension (msDBP ≥110 mmHg and/or msSBP ≥ 180 mmHg). 3. Pregnant or nursing (lactating) women, where pregnancy is defined as a state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test (≥ 5 mIU/ml). 4. Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, including women whose career, lifestyle, or sexual orientation precludes intercourse with a male partner and women whose partners have been sterilized by vasectomy or other means, UNLESS they are using two birth control methods. The two methods can be a double barrier method (if accepted by local ethics committee) or a barrier method plus a hormonal method. Adequate barrier methods of contraception include: diaphragm, condom (by the partner), intrauterine device (copper or hormonal), sponge or spermicide. Hormonal contraceptives include any marketed contraceptive agent that includes an estrogen and/or a progestational agent. Reliable contraception should be maintained throughout the study and for 7 days after the study. Woman are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum FSH levels > 40 mIU/ml [for US only: and estradiol <20 pg/ml] or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment. 5. History or evidence of a secondary form of hypertension. 6. Known Keith-Wagener grade III or IV hypertensive retinopathy. PLS SEE PROTOCOL
