NCT02945800 | Completed Phase 2 Results FDA Drug

• 1 other identifier: MCC-18613
• Study Type: interventional
• Target: 59
• Locations: 1 country
• Sites: 14

Brief Summary

The purpose of this study is to see if nab-paclitaxel combined with gemcitabine prevents the formation or growth of tumors in participants with relapsed or refractory osteosarcoma, Ewing sarcoma, rhabdomyosarcoma and other soft tissue sarcoma and to measure the length of time during and after treatment that their disease does not get worse. Researchers also want to find out if nab-paclitaxel combined with gemcitabine is safe and tolerable.

Conditions

Osteosarcoma; Ewing Sarcoma; Rhabdomyosarcoma; Soft Tissue Sarcoma

Keywords

relapsed; refractory; soft tissue; bones and joints; non-rhabdomyosarcoma soft tissue sarcoma; pediatric

Outcome Measures

Primary Outcomes (2)

• Response Rate

  Treatment response will be assessed with the most relevant imaging studies (e.g., CT or MRI) after every two cycles. Standard Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 will be used to assess responses. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm (\<1 cm). Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

  13 months

• Progression Free Survival (PFS)

  Progression-free survival (PFS) is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm (0.5 cm).

Eligibility Criteria

• Age: 3 Years - 30 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• Participants must be age ≥ 3 and ≤ 30 years, and have had a histologic diagnosis of osteosarcoma, Ewing sarcoma, or rhabdomyosarcoma or non-rhabdomyosarcoma soft tissue sarcoma either at diagnosis or relapse. Must have experienced relapse after front-line therapy, or have had documented disease progression during front-line therapy.
• Must have measurable disease that can be assessed using Response Evaluation in Solid Tumors (RECIST) 1.1, defined as the presence of at least one lesion on MRI or CT scan that can be accurately measured with the longest diameter of 10 mm in at least one dimension. For this phase II trial, patients with disease limited to bone or marrow metastases are NOT eligible, as disease at these sites cannot be assessed by RECIST 1.1 criteria.
• Must have relapsed or refractory cancers for which there is no known curative option.
• Prior Therapy: There is no limit to the number of prior therapies provided all eligibility criteria are met. However, participants must have recovered from the acute toxic effects of all prior treatment. (A) Must not have received prior therapy with either gemcitabine or nab-paclitaxel. (B) Myelosuppressive chemotherapy: Must not have received myelosuppressive chemotherapy within 3 weeks of protocol therapy on this study. (C) Hematopoietic growth factors: 7 days must have elapsed from the start of protocol therapy since the completion of therapy with filgrastim, and 14 days must have elapsed from the start of protocol therapy after receiving pegfilgrastim. (D) Biologic (anti-neoplastic agent): 7 day must have elapsed from the start of protocol therapy since the completion of therapy with a biologic agent. (E) Monoclonal antibodies: 3 half-lives must have elapsed from the start of protocol therapy since prior therapy that included a monoclonal antibody. (F) Radiotherapy: 2 weeks must have elapsed from the start of protocol therapy since local palliative radiotherapy (small port); 3 months must have elapsed if 50% radiation of pelvis; 6 weeks must have elapsed if other substantial bone marrow irradiation was given. (G) Stem Cell Transplant or Rescue: No evidence of active graft vs. host disease and 2 months must have elapsed from the start of protocol therapy since transplant.
• Karnofsky performance score must be ≥ 60
• Must have organ and marrow function
• Neuropathy: Must have ≤ grade 1 neuropathy at enrollment
• Central nervous system (CNS) Metastases: Potential participants with known CNS metastases are excluded unless treated surgically or with radiotherapy and stable with no recurrent lesions for at least 3 months from the start of protocol therapy.
• Contraception: Women of child-bearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation. Men treated or enrolled on this protocol must also agree to use adequate contraception 4 months after completion of gemcitabine and nab-paclitaxel administration.
• Consent: Participants must have the ability to understand and the willingness to sign a written informed consent or assent document.

You may not qualify if:

• Potential participants who are receiving any other investigational agents
• Must not be receiving any additional medicines being given for the specific purpose of treating cancer
• A history of allergic reactions attributed to docetaxel or paclitaxel
• Concomitant Medications: The metabolism of paclitaxel is catalyzed by CYP2C8 and CYP3A4. The following medicines should be avoided on this study because of their ability to inhibit or induce with CYP2C8 or CYP3A4: A) Inhibitors: ketoconazole and other imidazole antifungals, erythromycin, fluoxetine, gemfibrozil, cimetidine, ritonavir, saquinavir, indinavir, and nelfinavir. B) Inducers: Rifampicin, carbamazepine, phenytoin, efavirenz, and nevirapine. C) Potential participants receiving any of the above medications are ineligible.
• Potential participants are ineligible if they have uncontrolled intercurrent illness including, but not limited to: ongoing or active infection; symptomatic congestive heart failure; unstable angina pectoris; cardiac arrhythmia; psychiatric illness/social situations that would limit compliance with study requirements.
• Pregnant or breastfeeding
• HIV Infection: HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with the study medications.
• Anyone who in the opinion of the investigator may not be able to comply with the safety monitoring requirements of the study.
