Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1, open-label, randomized, PK and safety study in a maximum of 25 healthy subjects who have provided a bronchoalveolar lavage (BAL) sample.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1, open-label, randomized, PK and safety study in a maximum of 25 healthy subjects who have provided a bronchoalveolar lavage (BAL) sample. The dose planned to be administered in this study is an iv infusion of 30 mg TP 6076 q24h for 4 consecutive days (starting on Day 1 and ending on Day 4).

Subjects will be randomized to undergo a BAL at a single time point: either 2, 4, 8, or 24 hours after the start of the final TP-6076 iv infusion on Day 4. The BAL will be conducted in 5 different subjects at each of the 4 time points, adding up to a total of 20 subjects.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Status : Healthy subject
2. Gender : Male or female
3. Age : 18 to 50 years, inclusive, at screening
4. Body mass index (BMI) : 18.0 to 30.0 kg/m2, inclusive, at screening
5. Weight : 50 to 105 kg, inclusive, at screening
6. At screening, females must be non-pregnant and non-lactating, or of non childbearing potential (either surgically sterilized or physiologically incapable of becoming pregnant, or at least 1 year post menopausal \[amenorrhoea duration of 12 consecutive months\]); non-pregnancy will be confirmed for all females by a serum pregnancy test conducted at screening, admission to the CPU, and follow up.
7. Post-menopausal females using hormone replacement therapy should be on a stable regimen and be using this since at least 3 months prior to the first study drug administration.
8. Female subjects of childbearing potential who have a fertile male sexual partner must agree to use adequate contraception from screening until 90 days after the follow up visit. Adequate contraception will be methods with low user dependency (ie, implanted hormonal contraception, an intrauterine device, an intrauterine hormone releasing system, bilateral tubal occlusion, and/or a sole vasectomised male partner with medical assessment). Also, total abstinence, in accordance with the lifestyle of the subject, is acceptable.
9. Male subjects, if not surgically sterilized, must agree to use adequate contraception when engaging in sexual activity with a female of childbearing potential and not to donate sperm from admission to the CPU until 90 days after the follow-up visit. Adequate contraception for the male subject (and his female partner) will be methods with low user dependency (ie, implanted hormonal contraception, an intrauterine device, an intrauterine hormone releasing system, bilateral tubal occlusion, and/or a sole vasectomised male subject with medical assessment). Also, total abstinence, in accordance with the lifestyle of the subject, is acceptable.
10. All prescribed medication must have been stopped at least 30 days prior to admission to the CPU. An exception is made for hormonal contraceptives and a stable regimen of hormone replacement therapy, which may be used throughout the study.
11. All over-the-counter medication, vitamin preparations and other food supplements, or herbal medications (eg, St. John's Wort) must have been stopped at least 14 days prior to admission to the CPU. An exception is made for paracetamol, which is allowed up to admission to the CPU.
12. Ability and willingness to abstain from alcohol, methylxanthine-containing beverages or food (coffee, tea, cola, chocolate, energy drinks), and grapefruit (juice) from 48 hours prior to admission to the CPU.
13. Good physical and mental health on the basis of medical history, physical examination, clinical laboratory, ECG, and vital signs, as judged by the Investigator.
14. Willing to comply with the study procedures.
15. Willing and able to sign the ICF.

2. Employee of PRA Health Sciences (PRA), Hammersmith Medicines Research Ltd. (HMR), or Tetraphase Pharmaceuticals, Inc.
3. Subjects who may not tolerate a BAL, or cannot undergo a BAL due to the presence of contraindications to a BAL (including abnormal blood coagulation parameters, refractory hypoxemia, reactive airway disease or asthma, unstable angina or acute myocardial infarction in the 6 months prior to the first study drug administration).
4. History of any relevant lung disease.
5. History of relevant drug (including tetracycline-class antibiotics) and/or food allergies.
6. Using tobacco products or electronic cigarettes within 6 months prior to the first study drug administration.
7. History of alcohol abuse or drug addiction (including soft drugs like cannabis products) within 2 years prior to the first study drug administration.
8. Positive drug and alcohol screen (opiates, methadone, cocaine, amphetamines \[including ecstasy\], cannabinoids, barbiturates, benzodiazepines, tricyclic antidepressants, cotinine, and alcohol) at screening and admission to the CPU.
9. Average intake of more than 24 units of alcohol per week: 1 unit of alcohol equals approximately 250 mL of beer, 100 mL of wine, or 35 mL of spirits).
10. Positive screen for hepatitis B surface antigen (HBsAg), antihepatitis C virus (HCV) antibodies, or antihuman immunodeficiency virus (HIV) 1 and 2 antibodies.
11. Participation in a drug study within 60 days prior to the first study drug administration in the current study. Participation in more than 3 other drug studies in the 10 months prior to the first study drug administration in the current study.
12. Donation or loss of more than 400 mL of blood within 90 days prior to the first study drug administration. Donation or loss of more than 1.5 liters of blood (for male subjects)/more than 1.0 liters of blood (for female subjects) in the 10 months prior to the first study drug administration in the current study.
13. Significant and/or acute illness within 5 days prior to the first study drug administration that may impact safety assessments, in the opinion of the Investigator.
14. Unsuitable veins for infusion or blood sampling.
