Brief Summary:
The goals of this clinical research study are to see how individuals with advanced head and neck cancer respond to treatment with the new drug thrombospondin (ABT-510) and to learn how effective it is in destroying cancer cells. The safety of ABT-510 and the effect ABT-510 has on cells in the body will also be studied.

Condition or disease Intervention/treatment Phase
Head and Neck Cancer Drug: ABT-510 Phase 1 Phase 2

Detailed Description:

This is a phase Ib/II, single-center, open-label study designed to assess the safety, tolerability, pharmacokinetics, and biologic efficacy of ABT-510 (thrombospondin). Participants will be patients with incurable head and neck cancer.

Patients will begin at a fixed dose level of thrombospondin subcutaneously twice daily. Cycles of treatment are 28 days (4 weeks). Patients will be treated with thrombospondin until progression of tumor or toxicity.

Arm Intervention/treatment
Experimental: ABT-510 (Thrombospondin)
Fixed dose level of thrombospondin 100 mg subcutaneously twice daily.
Drug: ABT-510
100 mg subcutaneously twice daily
Other Name: Thrombospondin Analogue

Primary Outcome Measures :
  1. Response Rate [ Time Frame: Baseline to 6 weeks for PR or CR response assessment (minimal 4 week cycle + assessments). Overall study period 3 years. ]
    Response rate defined as percentage of number of complete response or partial response in total number of participants treated. Response Evaluation Criteria in Solid Tumors (RECIST): Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): >30% decrease in sum longest diameter (LD) of target lesions, reference baseline sum LD; Progressive Disease (PD): >20% increase in sum LD of target lesions, reference smallest sum LD recorded since treatment started or appearance of 1/> new lesions; Stable Disease (SD): Neither sufficient shrinkage for PR nor sufficient increase for PD, reference smallest sum LD. Trial conducted by Simon's optimal two-stage design and response rate estimated accordingly. For status of PR or CR, changes in tumor measurements confirmed by repeat assessments performed at 6 weeks, no less than 4 weeks after criteria for response is first met.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patient has histologically proven squamous cell carcinoma of the head and neck that is not amenable to curative therapy, including radiation or surgery (including surgery following induction chemotherapy or chemo-radiation).
  • Patient's tumor is biopsy accessible.
  • Patient has a Karnofsky performance status >/= 70.
  • Patient has adequate bone marrow function: White blood count (WBC) >/= 3,000 cells/mm3, absolute neutrophil count (ANC) >/= 1,500 cells/mm3, platelet count >/= 100,000 cells/mm3, Hgb >/= 9.0 g/dL.
  • Patient has adequate liver function: total bilirubin level </= 2.0 mg/dL, albumin >/= 2.5 g/dL.
  • Transaminases (SGOT and/or SGPT) may be up to 2.5 * upper limit of normal (ULN) if alkaline phosphatase is </= ULN, or alkaline phosphatase may be up to 4 x ULN if transaminases are </= ULN. However, patients who have both transaminase elevation > 1.5 * ULN and alkaline phosphatase > 2.5 * ULN are not eligible for this study.
  • Patient has serum creatinine < 2 mg/dl
  • Patient has signed a written informed consent.
  • Patient may have received any number of prior chemotherapeutic regimens for recurrent or metastatic disease.
  • The subject must not be pregnant or breastfeeding. All subjects (male and female) should practice contraception (e.g., barrier, hormonal, intrauterine device [IUD]) or abstain from sexual intercourse while in the study and for up to two months following completion of therapy.
  • The subject is able to self-administer or has a caregiver who can reliably administer subcutaneous (SC) injections.
  • Patient >/= 18 years of age.

Exclusion Criteria:

  • No biopsy accessible tissue.
  • Patient has received prior radiation therapy to biopsy site within the past 3 months. (Patient may have received palliative radiation within the past 2 weeks, but not to the biopsy site.)
  • Patient exhibits confusion, disorientation, or has a history of major psychiatric illness which may impair patient's understanding of the informed consent.
  • Patient requires total parenteral nutrition with lipids.
  • Patient has a history of uncontrolled heart disease including congestive heart failure, angina at rest, myocardial infarct in the last 6 months, uncontrolled hypertension with systolic blood pressure (BP) >160 or diastolic BP >90, systolic blood pressure (BP) <90 or symptomatic hypotension, or symptomatic or potentially life-threatening tachycardia, bradycardia or arrhythmia.
  • Pregnant women and women who are currently breast-feeding may not participate in this study. All women of childbearing potential must have a negative pregnancy test within 24 hours prior to enrolling in the study.
  • Serious infection or other intercurrent illness requiring immediate therapy.
  • The subject has a history of or currently exhibits clinically significant cancer related events of bleeding (e.g., hemoptysis). The subject has a recent history of (within 4 weeks from Study Day 1) or currently exhibits other clinically significant events of bleeding.
  • If subject is receiving therapeutic anticoagulation therapy, low dose anticoagulation for catheter prophylaxis will be permitted; PT/PTT must be within normal limits.
  • The patient has a history of or currently exhibits central nervous system (CNS) metastasis. Brain magnetic resonance imaging (MRI) within 28 days of enrollment is required to confirm the absence of CNS metastases.
  • Patient has received chemotherapy or biologic therapy within 3 weeks of registration.
