The objective of LIN-MD-64 is to evaluate the safety and efficacy of 12 weeks of linaclotide therapy (72 μg daily) in comparison with placebo in pediatric participants, 6 to 17 years of age, who fulfill modified Rome III Criteria for Child/Adolescent Functional Constipation (FC). The objective of LIN-MD-64 is to evaluate the safety and efficacy of 12 weeks of linaclotide therapy (145 μg or 290 μg daily) in pediatric participants, 7 to 17 years of age, who fulfill the Rome III criteria for child/adolescent Irritable Bowel Syndrome (IBS) and modified Rome III criteria for child/adolescent Functional Constipation (FC).

a. History of retentive posturing or excessive volitional stool retention; b. History of painful or hard BMs; c. History of large diameter stools that may obstruct the toilet; d. Presence of a large fecal mass in the rectum; e. At least 1 episode of fecal incontinence per week
For IBS-C participants only: Participant meets Rome III criteria for child/adolescent IBS: At least once per week for at least 2 months before the Screening Visit, the participant experienced abdominal discomfort (an uncomfortable sensation not described as pain) or pain associated with 2 or more of the following at least 25% of the time:
For IBS-C participants only: Participant has an average daytime abdominal pain score of ≥ 1 (at least "a tiny bit") during the 14 days before Visit 3;
Participant is willing to discontinue any laxatives used before the Preintervention Visit in favor of the protocol- permitted rescue medicine;
Participant has an average of fewer than 3 SBMs per week during the 14 days before the randomization day and up to the randomization (including the morning eDiary assessments reported before administration of first dose of double-blind study intervention on the randomization day). An SBM is defined as a BM that occurs in the absence of laxative, enema, or suppository use on the calendar day of the BM or the calendar day before the BM;
Participant or parent/guardian/LAR or caregiver is compliant with eDiary requirements by completing both the morning and evening assessments for 10 out of the 14 days immediately preceding the Randomization Visit;
Female participants of childbearing potential must have a negative serum pregnancy test at the Screening Visit and a negative urine pregnancy test at the Randomization Visit prior to dosing;
Female participants who have had their first menstrual period and are sexually active must agree to use a reliable form of contraception;
Participant must provide written or verbal informed assent and the parent/guardian/LAR and caregiver must provide written informed consent before the initiation of any study-specific procedures;
Participant is able to read and/or understand the assessments in the eDiary device. If the participant is 6 to 11 years of age (FC participants) or 7 to 11 years of age (IBS-C participants) and does not meet this criterion, the interviewer-administered version of the eDiary must be used and the parent/guardian/LAR or caregiver who will be administering the interviewer-administered version of the eDiary must undergo training;
Participant must have acquired toilet training skills.
Exclusion criteria
For FC participants only: Participant meets Rome III criteria for Child/Adolescent IBS: At least once per week for at least 2 months before the Screening Visit, the participant has experienced abdominal discomfort (an uncomfortable sensation not described as pain) or pain associated with 2 or more of the following at least 25% of the time:
Participant reports having more than 1 loose, mushy stool (eDiary-recorded stool consistency of 6 on the Pediatric Bristol Stool Form Scale [p-BSFS]) or any watery stool (eDiary-recorded stool consistency of 7 on the p-BSFS) with any SBM that occurred in the absence of laxative use on the calendar day of the BM or the calendar day before the BM during the 14 days before the randomization day and up to the randomization (including the morning eDiary assessments reported before administration of first dose of double-blind study intervention on the randomization day);
Participant has a history of non-retentive fecal incontinence;
Participant has (a) fecal impaction at Visit 2 after failing outpatient clean-out during the Screening Period or (b) fecal impaction at Visit 3;
Participant has required manual disimpaction any time prior to randomization;
Participant currently has both unexplained and clinically significant alarm symptoms (lower GI bleeding [rectal bleeding or heme-positive stool], iron-deficiency anemia, or any unexplained anemia, or weight loss) and systemic signs of infection or colitis, or any neoplastic process;
Participant has clinically significant findings on a physical examination, vital sign assessment, electrocardiogram (ECG), or clinical laboratory test as determined by the investigator based on consideration of whether the finding could represent a safety concern or a condition that would be exclusionary, could prevent the participant from performing any protocol assessments, or could confound study assessments;
Participant has a history of drug or alcohol abuse;
Participant has any of the following conditions:
Participant has an acute or chronic condition that, in the investigator's opinion, would limit the participants' ability to complete or participate in this clinical study;
Participant has a known or suspected mechanical bowel obstruction or pseudoobstruction;

Participant has had surgery that meets any of the following criteria:
Participant used a protocol-specified prohibited medicine before the start of the Preintervention Period or failed to meet the stable-dose requirements of certain medications;
Participant used rescue medication on the calendar day before the Randomization Visit and on the day of the Randomization Visit until randomized;
Participant received a study intervention during the 30 days before the Screening Visit or is planning to receive a study intervention (other than that administered during this study);
Participant has been randomized into any clinical study in which linaclotide was a study intervention.
The participant has a condition or is in a situation; which, in the investigator's opinion, may put the participant at significant risk, may confound the study results ,or may interfere significantly with the participant's participation in the study;
Participants who have positive urine drug screen results for cocaine, barbiturates, opiates, or cannabinoids will be excluded from study participation;
Female participants who are currently pregnant or nursing, or plan to become pregnant or nurse during the clinical study;
Participant's parent/guardian/LAR or caregiver has been directly or indirectly involved in the conduct and administration of this study as an investigator, study coordinator, or other study staff member.
