Brief Summary:

The primary objective of this study is to compare the efficacy of Bonjesta for the treatment of nausea and vomiting of pregnancy (NVP) in pregnant adolescents aged 12 to 17 years with placebo.

The secondary objective of this study is to compare the safety of Bonjesta in pregnant adolescents aged 12 to 17 years with placebo.


Condition or disease Intervention/treatment Phase
Morning Sickness Drug: Bonjesta Drug: Placebo Phase 3

Detailed Description:

This is a phase III multicenter study designed to assess the efficacy and the safety of Bonjesta in the treatment of NVP in pregnant adolescents from approximately 14-16 study sites in the United States.

After obtaining informed consent on Day 1 (i.e., baseline visit), a medical examination will be conducted to ensure eligibility. Participants will be randomized to receive either Bonjesta or placebo.

On Day 1, all participants will take 1 tablet of study drug at bedtime. On Day 2, participants will take 1 tablet of study drug at bedtime. If the Pregnancy-Unique Quantification of Emesis (PUQE) score > 3, the participant will take another tablet of study drug in the morning of Day 3. Therefore, the minimum dosage will be 1 tablet daily at bedtime, increasing, when indicated (i.e., if PUQE > 3), to the maximal dosage of 2 tablets per day on Days 3 to 14. Participants will be required to complete a diary daily to assess the severity of their NVP using the validated PUQE scale and to record any adverse events (AEs) experienced; the Global Assessment of Well-being scale will also be completed in the diary only on Days 1, 8 and 15.

Participants will receive telephone calls daily to assess whether the current dosing regimen is sufficient at relieving NVP symptoms, to review study procedures, and to address the participants' questions/concerns. Participants will have study visits on Day 1, Day 3 (±1 day) and Day 15 (±1 day) for an end of study visit.

Arm Intervention/treatment
Active Comparator: Bonjesta
On Day 1, one tablet will be taken orally at bedtime. If this dose adequately controls symptoms (i.e., PUQE = 3), the participant will be directed to continue taking one tablet daily at bedtime only. However, on Day 2, if symptoms of nausea, retching and/or vomiting persist (i.e., PUQE score >3), the participant will be directed to take her usual dose of 1 tablet at bedtime and an additional tablet the next morning on Day 3. The minimum dosage prescribed will be 1 tablet daily at bedtime, increasing, when indicated, to the maximal dosage of 2 tablets per day (one tablet in the morning and one tablet at bedtime) starting Day 3 and will continue through Day 14.
Drug: Bonjesta
Extended-release tablets contain 20 mg of doxylamine succinate and 20 mg of pyridoxine hydrochloride. Minimum 1 tablet at bedtime. Up to two pills daily (one tablet in the morning and one tablet at bedtime). The treatment duration is 15 days.

Placebo Comparator: Placebo
On Day 1, one tablet will be taken orally at bedtime. If this dose adequately controls symptoms (i.e., PUQE = 3), the participant will be directed to continue taking one tablet daily at bedtime only. However, on Day 2, if symptoms of nausea, retching and/or vomiting persist (i.e., PUQE score >3), the participant will be directed to take her usual dose of 1 tablet at bedtime and an additional tablet the next morning on Day 3. The minimum dosage prescribed will be 1 tablet daily at bedtime, increasing, when indicated, to the maximal dosage of 2 tablets per day (one tablet in the morning and one tablet at bedtime) starting Day 3 and will continue through Day 14.
Drug: Placebo
Sugar pills with no active ingredients. Minimum 1 tablet at bedtime. Up to two pills daily (one tablet in the morning and one tablet at bedtime). The treatment duration is 15 days.




Primary Outcome Measures :
  1. Nausea and Vomiting of Pregnancy Severity from Baseline to Day 15 [ Time Frame: Day 1-Day 15 ]
    The primary objective of this study is to compare the efficacy of Bonjesta with placebo for the treatment of NVP in pregnant adolescents aged 12 to 17 years. NVP severity will be compared using the change in PUQE score from baseline (Day 1) to Day 15 between adolescents randomized to Bonjesta and placebo.


Secondary Outcome Measures :
  1. Severity and occurrences of maternal adverse events [ Time Frame: Day 1-Day 15 ]
    The secondary objective of this study is to compare the safety of Bonjesta with placebo in pregnant adolescents aged 12 to 17 years by assessing differences in the severity and occurrence of AEs.

  2. Overall well-being from Baseline to Day 15 [ Time Frame: Day 1-Day 15 ]
    The secondary objective of this study is the change in the Global Assessment of Well-being score from baseline (Day 1) to Day 15 between adolescents randomized to Bonjesta and placebo.

Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  1. The study population will include pregnant adolescents who reside in the US and meet all of the following criteria for inclusion: The participant is a pregnant female between the following ages: at least 12 years on the day of recruitment (i.e., Day 1) and not yet 18 years on the last day of the study (i.e., Day 15).
  2. The participant must provide written informed consent and/or assent to participate in the study and agrees that she will follow dosing instructions and complete all required study visits.
  3. The participant's entry ultrasound indicates a viable singleton pregnancy and confirms gestational age of the fetus is 7-15 weeks + 0 days at the anticipated time of the first dose of study drug provided that her NVP symptoms began ≤ 10 weeks gestation. If an ultrasound was performed within 4 weeks of the study entry visit, and results can be obtained, an additional ultrasound is not necessary.
  4. The participant is suffering from NVP and has a PUQE score ≥ 6.
  5. The participant has not responded to conservative management consisting of dietary/lifestyle advice according to the 2018 ACOG Practice Bulletin.
  6. The participant agrees, if on a multivitamin, to continue on her current dose of multivitamin for the duration of the trial.
  7. The participant does not plan termination of the pregnancy.
  8. The participant is judged to be in good health based on her medical history, physical examination and laboratory tests
  9. The participant must be able to swallow the study drug whole (i.e., without splitting, crushing, or chewing the tablets) on an empty stomach.

Exclusion Criteria:

  1. The investigator confirms the participant's nausea and vomiting is of etiology other than NVP.
  2. The participant has gestational trophoblastic disease or multifetal gestation.
  3. The participant has a condition for which antihistamines, in the opinion of the investigator, are contraindicated (e.g., epilepsy, alcoholism, glaucoma, chronic lung disease, urinary retention, and heart block).
  4. The participant has a known hypersensitivity to doxylamine succinate, other ethanolamine derivative antihistamines, pyridoxine hydrochloride, or any inactive ingredient in the Bonjesta or placebo formulation.
