Intraperitoneal Paclitaxel for the Treatment of Patients with Metastatic Appendiceal Adenocarcinoma
This phase I/II trial tests the safety, side effects, best dose and effectiveness of paclitaxel given directly into the abdominal cavity (intraperitoneal) in treating patients with metastatic appendix cancer. Cancer of the appendix, such as appendiceal adenocarcinoma, is rare and is often diagnosed after the tumor has spread to the abdominal cavity (peritoneal). Systemic treatment has been shown to have a limited effect that may be due to the peritoneum-plasma barrier which prevents effective drug delivery into the peritoneal cavity. Paclitaxel is in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. Paclitaxel when given in the peritoneal cavity may provide a higher drug exposure in the peritoneal cavity and reduce side effects due to systemic therapy. Giving paclitaxel intraperitoneally may be safe, tolerable and/or effective in treating patients with metastatic appendiceal adenocarcinoma.
Inclusion Criteria
- Age 18 years and above. There will be no upper age restriction
- Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
- Patients must have histologically confirmed diagnosis of unresectable locally metastatic appendiceal adenocarcinoma and have undergone less than four prior lines of systemic therapy
- Patients must have adequate nutrition and normal bowel motility and function as evidenced by: * Albumin > 3.0 * No recent history (within last 2 mos) of bowel obstruction that resolved spontaneously or with surgical intervention * No history of internal intestinal bypass or diverting enterostomy
- Leukocytes ≥ 3000/mcL
- Absolute neutrophil count ≥ 1,500/mcL
- Platelets ≥ 75,000/mcL
- Total bilirubin ≤ institutional upper limit of normal (ULN)
- Creatinine ≤ 1.5 X institutional ULN
- For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
- Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
- Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
- The effects of PTX on the developing human fetus are unknown. For this reason, and because taxane agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. (Refer to Pregnancy Assessment Policy MD Anderson Institutional Policy # CLN1114). This includes all female patients, between the onset of menses (as early as 8 years of age) and 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following: * Postmenopausal (no menses in greater than or equal to 12 consecutive months) * History of hysterectomy or bilateral salpingo-oophorectomy * Ovarian failure (follicle stimulating hormone and estradiol in menopausal range, who have received whole pelvic radiation therapy) * History of bilateral tubal ligation or another surgical sterilization procedure Approved methods of birth control are as follows: hormonal contraception (i.e., birth control pills, injection, implant, transdermal patch, vaginal ring), intrauterine device (IUD), tubal ligation or hysterectomy, subject/partner post vasectomy, implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of paclitaxel administration.
- Ability to understand and the willingness to sign a written informed consent document
- English and non-English-speaking patients
Exclusion Criteria
- Active infection such as pneumonia or wound infections that would preclude protocol therapy
- Subjects with unstable angina or New York Heart Association (NYHA) grade II or greater congestive heart failure
- Subjects deemed unable to comply with study and/or follow-up procedures (i.e., cognitive impairment)
- Subjects with a known hypersensitivity to protocol systemic chemotherapy that was life-threatening, required hospitalization or prolongation of existing hospitalization, or resulted in persistent or significant disability or incapacity
- Previous surgery that would preclude safe diagnostic laparoscopy with port placement
- Features of patient’s peritoneal disease that might increase the risk of small bowel obstruction and/or small bowel perforation as determined by review of radiographs * Foreshortening of small bowel mesentery and likelihood for dense adhesive disease * Areas concerning for abscess and/or contained perforation * Areas concerning for enteric fistula
- Patients with history of chronic abdominal pain requiring routine use of narcotic pain medication
- Patients with large volume ascites requiring repeated paracenteses
- Patients who have not recovered from adverse events (AE) due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1) with the exception of alopecia
- Patients who are receiving any other investigational agents
- Patients with metastases outside the peritoneal cavity, with exception of limited metastases to the thoracic cavity
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to PTX or other agents used in study
- Patients with psychiatric illness/social situations that would limit compliance with study requirements
- Patients who are pregnant

PRIMARY OBJECTIVES:
I. To assess the maximum tolerated dose (MTD) of paclitaxel via intraperitoneal (IP) route given every 14 days in subjects with metastatic appendiceal adenocarcinoma. (Phase I)
II. To assess the pathologic, biochemical, and radiographic objective response rate of paclitaxel via IP route in patients with metastatic appendiceal adenocarcinoma. (Phase II)
SECONDARY OBJECTIVES:
I. To assess the progression-free and overall survival of metastatic appendiceal adenocarcinoma treated with IP paclitaxel.
II. To assess the pharmacokinetics of IP paclitaxel (PTX).
III. To assess the change in Peritoneal Cancer Index (PCI) following IP PTX in patients with metastatic appendiceal adenocarcinoma.
IV. To assess rate of initially unresectable patients with metastatic appendiceal adenocarcinoma able to undergo cytoreductive surgery (CRS) / heated intraperitoneal chemotherapy (HIPEC) after IP PTX.
V. To assess the rate of conversion from positive to negative cytology in peritoneal fluid following IP PTX in patients with metastatic appendiceal adenocarcinoma.
VI. To assess the prognostic value of circulating tumor deoxyribonucleic acid (DNA) (ctDNA) in patients with metastatic appendiceal adenocarcinoma and the correlation of quantitative ctDNA measurement with radiographic and pathologic response.
VII. To generate patient-derived xenograft (PDX) and patient-derived organoids (PDO) models of appendiceal adenocarcinoma and evaluate their ability to predict response of human tumors.
VIII. To evaluate the effect of IP PTX on the transcriptomic state of appendiceal adenocarcinoma and the tumor microenvironment (TME) through comparison of pre- and post-treatment specimens.
IX. To assess the impact of GNAS, KRAS, TP53, and APC mutation on response to IP PTX therapy.
X. To assess the impact of mucinous, signet ring cell, and goblet cell histology on response to IP PTX therapy.
OUTLINE: This is a dose-escalation study of intraperitoneal paclitaxel followed by a dose-expansion study.
Patients receive paclitaxel IP over at least 30 minutes every 2 weeks for up to 4 doses over 8 weeks. Additionally, patients undergo blood sample collection, computed tomography (CT) scan, or positron emission tomography (PET)/CT scan at baseline and throughout the trial.
At the completion of study treatment, patients are followed up every 12 weeks for up to 1 year.
