Complicated Intra Abdominal Infections | Antibiotic Safety (SCAMP)

Complicated Intra Abdominal Infections research study

What is the primary objective of this study?

The main purpose of this study is evaluate whether it is safe or not to use various combination of antibiotics (ampicillin, metronidazole, clindamycin, piperacillin-tazobactam, gentamicin) in treating infants with complicated intra-abdominal infections

Who is eligible to participate?

Inclusion Criteria: 1. Informed consent obtained from parent(s) or legal guardian(s) (Groups 1-5) 2. ≤33 weeks gestation at birth (Groups 1-3, 5) 3. ≥34 weeks gestation at birth (Groups 4 and 5) 4. PNA <121 days (Groups 1-5) 5. Sufficient venous access to permit administration of study drug (intravenous [IV]) (Groups 1-5) 6. Presenting physical, radiological, and/or bacteriological findings of a complicated intra-abdominal infection within 48 hours prior to randomization/first study drug dose (Groups 1-4)**. Complicated intra-abdominal infections include secondary peritonitis, NEC grade II or higher by Bell's criteria, Hirschsprung's disease with perforation, spontaneous intestinal perforation, meconium ileus with perforation, bowel obstruction with perforation, gastroschisis with necrosis and/or perforation, omphalocele with necrosis and/or perforation, neonatal appendicitis, intestinal pneumatosis or portal venous gas, free peritoneal air on abdominal radiographic examination, or abdominal abscess. 7. Suspected or confirmed infection for which the study drug may provide therapeutic benefit and planned CSF collection per standard of care (Group 5). Exclusion Criteria* 1. History of anaphylaxis in response to study drugs (Groups 1-5) 2. Serum creatinine >2 mg/dL within 48 hours on measurement prior to and closest to randomization /first study drug dose (Groups 1- 5)** 3. Known ALT >250 U/L or AST >500 U/L on measurement closest to the time of randomization or first study drug dose (Groups 1-5)** 4. Any condition that, in the judgment of the investigator, precludes participation because it could affect participant safety (Groups 1-5) - Do not apply for Group 5 participants receiving drug per standard of care - Criteria must be satisfied by randomization (randomized Groups 1-3) or first study drug dose (non-randomized Groups 1-3, Group 4 and Group 5), whichever comes first.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:ampicillin and metronidazole and gentamicinIV infusion of ampicillin and metronidazole and gentamicin for a total of 10 days. Dose based on postnatal age (PNA) and gestational age(GA)

Drug:ampicillin and gentamicin and clindamycinIV infusion of ampicillin and gentamicin and clindamycin for a total of 10 days. Dose based on postnatal age (PNA) and gestational age(GA)

Drug:gentamicin and Piperacillin- tazobactamIV infusion of gentamicin and Piperacillin- tazobactam for a total of 10 days. Dose based on postnatal age (PNA) and gestational age(GA)

Drug:standard of care antibiotics and metronidazoleIV infusion of standard of care antibiotics and metronidazole for a total of 10 days. Dose based on postnatal age (PNA) and gestational age(GA)

Drug:metronidazole, clindamycin, or piperacillin-tazobactamIV infusion of metronidazole, clindamycin, or piperacillin-tazobactam with scheduled CSF procedures per standard of care. Study drug will be given for for a total of 10 days. Dose based on postnatal age (PNA) and gestational age(GA)

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Group 1 (ampicillin +gentamycin +metronidazole)Ampicillin and gentamycin and metronidazole

Group 2 (ampicillin +gentamicin+clindamycin)ampicillin and gentamicin and clindamycin

Group 3 (piperacillin-tazobactam and gentamicin)piperacillin-tazobactam and gentamicin

Group 4 (metronidazole)Per standard of care antibiotics, and Metronidazole

Group 5 (metronidazole/clindamycin/piperacillin-tazobactam)metronidazole, clindamycin, or piperacillin-tazobactam
