Key inclusion & exclusion criteria

Signed and dated informed consent will be obtained from each subject (only include those able to consent) in accordance with the local regulatory and legal requirements 8. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures. Subjects who are willing, but need assistance for self administered questionnaires may be considered acceptable, but must first be discussed on a caseby- case basis with the Pfizer monitor prior to any to any screening tests or procedures for the study.

Any history of known brain metastases, spinal cord compression, or evidence of symptomatic brain or leptomeningeal carcinomatosis 4. Presence of neuropathic pain or peripheral polyneuropathy or identified causes of painful paresthesia including radiotherapy-induced or malignant plexopathy, lumbar or cervical radiculopathy existing prior to baseline 5. A current medical diagnosis that could potentially lead to the development of neuropathic pain over the course of the study (e.g. HIV neuropathy, herpes zoster) or pre-existing peripheral neuropathy of another etiology, including: (e.g. B12 deficiency, AIDS, monoclonal gammopathy, diabetes, heavy metal poisoning, amyloidosis, syphilis, hyperthyroidism or hypothyroidism, inherited neuropathy) 6. A diagnosis of dihydro-pyrimidine-dehydrogenase (DPD) deficiency prior to baseline 7. A medical diagnosis of renal failure prior to baseline 8. History of neoplasm other than colorectal carcinoma, except for: radically treated non melanoma skin cancer or in situ carcinoma of cervix 9. Recent history of myocardial infarction within 6 months from study entry, uncontrolled hypertension or high risk uncontrolled arrhythmias, unstable angina pectoris 10. A previous history of intolerance or hypersensitivity to pregabalin, gabapentin, or other drugs structurally similar to the neurotransmitter GABA 11. Creatinine Clearance <30 mL/min (from serum creatinine). Maximum dose for subjects with creatinine clearance of 30-60 mL/min is 300mg/day 12. Hematological values: WBC < 2.5 X 103/ul ; Platelets < 100 X 103/ul at screening 13. Clinically significant abnormal 12-lead electrocardiogram (ECG). 14. Abuse of illicit drugs or alcohol within the past 2 years 15. In the judgment of the investigator the subject is unable or unlikely to follow the protocol, or otherwise might not be suitable for the study 16. In the judgment of the investigator, any subject unable to understand the nature, scope, procedures and possible consequences of the study and/or evidence of an uncooperative attitude 17. Participation in any other studies involving investigational or marketed products, concomitantly or within 30 days prior to entry in the study 18. Previous use of gabapentin or pregabalin within 30 days prior to randomization or likelihood of engaging in these treatments during the study period 19.

Primary Outcome(s)

Main Objective: To evaluate the time to onset of moderate-severe persistent paresthesic positive symptoms of chemotherapy-induced neuropathy defined as a minimum score >/= 4 assessed with the Numeric Rating Scale (NRS) from the onset of chemotherapy or emergence of a chemotherapy dose reduction or delay of chemotherapy cycle due to severity of chemotherapy-induced neuropathy. The persistent paresthesic positive symptoms will be measured by a modified NRS (Numeric Rating Scale) which assesses paresthesia rather than pain.

Primary end point(s): The time to onset of moderate-severe persistent paresthesic positive symptoms of chemotherapyinduced neuropathy defined as a minimum score >/= 4 assessed with the Numeric Rating Scale (NRS) from the onset of chemotherapy.

Secondary Objective: To evaluate the time to onset of any paresthesic positive symptoms of the chemotherapy-induced neuropathy from the onset of chemotherapy. To evaluate the time to onset of persistent dysesthesic and pain positive symptoms of chemotherapy-induced neuropathy from time of initial chemotherapy, as measured using the modified NRS. To evaluate the time to onset of acute positive neuropathic symptoms (paresthesia, dysesthesia and pain) as defined in the background section of the chemotherapy-induced neuropathy from time of initial chemotherapy to the last cycle. To evaluate the parasthesic, dysesthesic, and pain symptoms score over each chemotherapy cycle. To evaluate the proportion of subjects experiencing positive neuropathic symptoms in each treatment group at endpoint. To evaluate the time to onset of the chemotherapy-induced cold intolerance developed from time of initial chemotherapy to the last cycle.
