* Participants are men or non-pregnant, non-lactating women. Sexually active women must be postmenopausal, surgically sterile, or practicing an effective method of birth control (e.g., prescription oral contraceptives, contraceptive injections, intrauterine device, double barrier method, contraceptive patch, male partner sterilization) before entry and throughout the trial. Women of childbearing potential must have a negative pregnancy test at screening.
* Participants must be appropriately communicative to verbalize and to differentiate with regard to location and intensity of the pain.
* Participants must be at least 18 years of age.
* Participants must have a diagnosis of chronic low back pain; chronic pain defined as pain lasting for at least 3 months
* If the Participant has radicular pain, this must have been present for at least 3 months and stable for the 4 weeks before enrollment.
* Participant's pain must require a strong analgesic (defined as WHO Step III) as judged by the Investigator.
* Participants must be taking a WHO Step III analgesic on a daily basis for at least 3 months prior to the Screening Visit.
* Participants must have responded to the WHO Step III analgesic, i.e., participants must have a confirmed average pain intensity score (NRS 3) of ≤5 points during the last 3 days prior to the Screening Visit.
* Participants must report opioid-related side effects as the reason to change their analgesic.
* Participants must report a rate of satisfaction with their previous analgesic regimen not exceeding "fair" on a subject satisfaction with treatment scale (5-point VRS).
Exclusion Criteria:
* Presence of a clinically significant disease or laboratory findings that in the Investigator's opinion may affect efficacy or safety assessments.
* Presence of active systemic or local infection that may, in the opinion of the Investigator, affect the efficacy, quality of life/function or safety assessments.
* History of alcohol or drug abuse, or suspicion of in Investigator's judgement.
* Presence of concomitant autoimmune inflammatory conditions.
* Known history of or laboratory values reflecting severe renal impairment.
* Known history of moderately or severely impaired hepatic function.
* History of or active hepatitis B or C within the past 3 months or history of HIV infection.
* History of seizure disorder or epilepsy.
* Any of the following within 1 year: mild/moderate traumatic brain injury, stroke, transient ischemic attack, or brain neoplasm. Severe traumatic brain injury within 15 years (consisting of 1 or more of the following: brain contusion, intracranial hematoma, either unconsciousness or post traumatic amnesia lasting more than 24 h) or residual sequelae suggesting transient changes in consciousness.
* Pregnant or breast-feeding.
* History of allergy to, or hypersensitivity to tapentadol hydrochloride or its excipients, or contraindications related to tapentadol hydrochloride including:
* Subjects with acute or severe bronchial asthma or hypercapnia.
* Subjects who have or are suspected of having paralytic ileus.
* Employees of the Investigator or trial site, with direct involvement in this trial or other trials under the direction of the Investigator or trial site, as well as family members of employees of the Investigator.
* Participation in another trial concurrently or within 4 weeks prior to the Screening Visit.
* Known to or suspected of not being able to comply with the protocol and the use of the investigational medicinal product.
* Use of monoamine oxidase inhibitors within 14 days before the Screening Visit.
* Non-stable dosing of selective serotonin reuptake inhibitors within 30 days before the Screening Visit (the doses must remain stable during the trial).
* Presence of concomitant painful condition other than low back pain that could confound the subject's trial assessments or self evaluation of pain, e.g., anatomical deformities, significant skin conditions such as abscess or syndromes with widespread pain such as fibromyalgia.
* Any painful procedures during the trial (e.g., major surgery) that may, in the opinion of the Investigator, affect the efficacy or safety assessments.
* Pending litigation due to chronic pain or disability.
