Nab-paclitaxel and Carboplatin Followed by Response-Based Local Therapy in Treating Patients With Stage III or IV HPV-Related Oropharyngeal Cancer (OPTIMA)

An Exploratory Pilot Study of Nab-paclitaxel Based Induction Chemotherapy Followed by Response-Stratified Locoregional Therapy for Patients With Stage III and IV HPV-Related Oropharyngeal Cancer - the OPTIMA HPV Trial

This phase II trial studies nab-paclitaxel (paclitaxel albumin-stabilized nanoparticle formulation) and carboplatin followed by response-based local therapy in treating patients with stage III or IV human papillomavirus (HPV)-related oropharyngeal cancer. Drugs used in chemotherapy, such as paclitaxel albumin-stabilized nanoparticle formulation, carboplatin, hydroxyurea, fluorouracil, paclitaxel, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them spreading. Radiation therapy uses high energy x rays to kill tumor cells. Giving nab-paclitaxel and carboplatin before chemoradiation may make the tumor smaller and reduce the amount of chemotherapy and radiation therapy needed. Assigning chemotherapy and radiation therapy based on response (response-based therapy) and giving patients who are responding well lower doses of treatment may help reduce the occurrence of side effects.

II. Translational research on blood and tissue samples. III. To profile tumors genetically and immunologically in order to assess in a descriptive manner genetic or immunological features characteristic of clinical behavior.

OUTLINE:

INDUCTION CHEMOTHERAPY: All patients receive paclitaxel albumin-stabilized nanoparticle formulation intravenously (IV) over 60 minutes on days 1, 8, and 15 and carboplatin IV over 30-60 minutes on day 1. Treatment repeats every 21 days for 3 courses in the absence of disease progression or unacceptable toxicity.

Patients are then assigned to 1 of 3 treatment groups based on response to induction chemotherapy.

GROUP A (LOW-DOSE ARM): Patients undergo radiation therapy once daily for 5 weeks.

GROUP B (INTERMEDIATE-DOSE ARM): Patients receive hydroxyurea orally (PO) twice daily (BID) on days 0-5, fluorouracil IV continuously on days 1-5, and paclitaxel IV over 60 minutes on day 1. Patients also receive low-dose radiation therapy BID on days 1-5. Treatment repeats every 14 days for 3 courses in the absence of disease progression or unacceptable toxicity.

GROUP C (STANDARD-DOSE ARM): Patients receive hydroxyurea PO BID on days 0-5, fluorouracil IV continuously on days 1-5, and paclitaxel IV over 60 minutes on day 1. Patients also receive standard-dose radiation therapy BID on days 1-5. Treatment repeats every 14 days for up to 5 courses in the absence of disease progression or unacceptable toxicity.*

*NOTE: At the discretion of the principal investigator (PI), patients may receive cisplatin IV over 1-3 hours every 3 weeks during radiation therapy instead of paclitaxel and undergo daily radiation therapy.

After completion of study treatment, patients are followed up for 30 days, every 3 months for 1 year, every 6 months for 2 years, and then annually for 2 years.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-Free Survival (PFS), Evaluated Using RECIST Version (v) 1.1	If all patients are followed for two years, the PFS rate and confidence interval will be determined based on the exact binomial distribution. Otherwise, PFS will be estimated using the Kaplan-Meier method and a (large-sample) one-sided 90% confidence interval will be derived for the PFS rate at two years to test the non-inferiority hypothesis. Median PFS will be estimated as described in Brookmeyer and Crowley.	Time from enrollment until disease progression or death from any cause, assessed at 2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of Pathologic Complete Response (PCR) on Post Treatment Biopsy/Surgery, Evaluated Using RECIST v1.1	Pathologic response rates will be determined and 95% confidence intervals obtained using the exact binomial distribution.	Up to 8 weeks after completion of CRT
Clinical Complete Response by Computerized Tomography (CT) & Magnetic Resonance Imaging (MRI) Only	Clinical response rates will be determined and 95% confidence intervals obtained using the exact binomial distribution.	Up to 5 years
Overall Survival	Overall survival rate	From the date of registration to the date of death or date of last patient contact if censored, assessed up to 5 years
Cancer-specific Survival	Overall Cancer-specific survival rate. Patients dying from non-cancer related causes will be censored at the time of death.	Up to 5 years
Rates of Acute Toxicity, Determined by Incidence of Mucositis, Xerostomia, Anorexia, Weight Loss, Dermatitis and G-tube Placement	Toxicity rates will be summarized by type of toxicity, grade, and attribution. The incidence of acute (mucositis, xerostomia, anorexia, weight loss, dermatitis and G-tube placement) toxicities will be estimated along with 95% confidence intervals. Toxicity criteria of the Common Toxicity Criteria (CTC) and the Radiation Therapy Oncology Group (RTOG) will be used to determine grades. General CTC grade definitions: 0 = No adverse event or within normal limits; 1 = Mild adverse event; 2 = Moderate adverse event; 3 = Severe and undesirable adverse event; 4 = Life-threatening or disabling adverse event; 5 = Death related to adverse event. For Mucous, 3 = Confluent fibrinous, mucositis / may include severe pain requiring narcotic; 4 = Ulceration, hemorrhage or necrosis. For neutropenia, 3 = Neutrophils 0.5 - < 1.0; 4 = Neutrophils < 0.5 or sepsis.	Up to 5 years
Rates of Late Toxicity, Determined by Incidence of Xerostomia, Dental Decay, Osteroradionecrosis, G-tube Dependency, Tracheostomy Placement and Dysphagia	Toxicity rates will be summarized by type of toxicity, grade, and attribution. The incidence of late-term (xerostomia, dental decay, osteroradionecrosis, G-tube dependency, speech abnormalities, tracheostomy placement and dysphagia) toxicities will be estimated along with 95% confidence intervals.	Up to 5 years

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Histologic Appearance of Post-induction Tumor Tissue	Results of pathology/histologic review of post induction biopsy specimens will be descriptive and summarize in tabular format.	Up to 3 months post-treatment
