About this study

Official title: A Phase 1 Study Evaluating High Dose ADXS11-001 Treatment in Women With Carcinoma of the Cervix (ADXS001-07)

To evaluate the tolerability and safety of axalimogene filolisbac 1 x 10^10 colony forming units (cfu) administered with prophylactic premedication in repeating 3-dose study cycles in women with persistent, metastatic, or recurrent squamous and non-squamous carcinoma, adenosquamous, or adenocarcinoma of the cervix. To evaluate tumor response and progression-free survival (PFS) by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and immune-related Response Evaluation Criteria in Solid Tumors (irRECIST).

Read the detailed description

In this Phase 1, open-label, multicenter dose-escalation study, participants with persistent, metastatic, or recurrent carcinoma of the cervix who failed conventional therapy received axalimogene filolisbac every 3 weeks in repeating 12-week treatment cycles. Axalimogene filolisbac was administered intravenously (IV) on Day 1 of Weeks 1, 4, 7, and 10 of each cycle. Participants received a prophylactic regimen that was completed prior to each axalimogene filolisbac infusion to mitigate and manage potential immune responses seen with immunotherapy administration. The pretreatment prophylaxis regimen included commercially available antihistamines, nonsteroidal anti-inflammatory drugs (NSAIDs), antiemetics, histamine H2-receptor antagonists, and IV hydration. Additional NSAID doses and antiemetic administration were given post initial administration on Day 1 and Day 2, at the discretion of the investigator.

Participants received a 7-day course of oral antibiotic therapy starting approximately 72 hours (Day 4) after each administration of axalimogene filolisbac. Antibiotic therapy consisted of trimethoprim (80 mg)/sulfamethoxazole (400 mg) tablets (Bactrim) or trimethoprim (160 mg)/ sulfamethoxazole (800 mg) tablets (Bactrim DS), administered 3 times during the 7 consecutive days or ampicillin 500 mg 4 times daily for 7 consecutive days for participants with sulfa allergy.

Axalimogene filolisbac doses were to be escalated/de-escalated in the standard 3 + 3 fashion, starting with 5x10^9 cfu to a maximum dose level of 1x10^10 cfu. Dose cohorts of 3 participants each were to be treated. All decisions regarding dose escalation/de-escalation were made by the sponsor in consultation with investigators. In the absence of dose-limiting toxicity (DLT) assessed during the first 28 days in Cycle 1, the dose was to be escalated to the next dose level for the next 3 participants. If DLT was seen in 1 of 3 participants, another 3 participants were to be treated at that same dose. If DLT was seen in 2 of 6 participants, then that dose level was considered the Maximum Tolerated Dose (MTD) and the previous dose level was selected as the Recommended Phase 2 dose (RP2D). Specific hematologic and non-hematologic DLT criteria were prospectively defined in protocol. The RP2D was to be selected based on an observed DLT rate of <33%.

Additional participants were to be enrolled into an expansion cohort to allow approximately 15 participants to be treated at that dose level.

Treatment cycles were repeated at the RP2D (or less) for an individual participant until a discontinuation criterion was met. Discontinuation criteria included documented disease progression, intolerable side effects not resolved with dose reduction or change in premedication or the participant completed 1 cycle of treatment post observation of complete response (CR per RECIST 1.1 and immune-realted complete response [irCR] per irRECIST). Participants who experienced a DLT during the dose-escalation portion of the study or experienced events meeting the definition of a DLT as described in the protocol in any subsequent treatment cycle were to be discontinued from study treatment. However, if a participant who experienced a DLT showed significant response to axalimogene filolisbac, the participant could receive subsequent axalimogene filolisbac treatment at a lower dose level following discussion and agreement between the investigator and sponsor.

Efficacy was assessed by tumor imaging at the end of every cycle. Safety was assessed by analyzing treatment-related adverse events (AEs), changes in physical examinations, vital sign measurements, and clinical laboratory abnormalities. All toxicities were graded using Common Terminology Criteria for Adverse Events (CTCAE) 4.03.

After the study treatment period, all participants were to participate in a 3-year Lm surveillance monitoring period that included a 6-month course of antibiotics to be initiated 72 hours after completion of treatment or immediately following study discontinuation and monitoring (Complete blood count [CBC], comprehensive metabolic panel, and blood cultures for the detection of Lm) every 3 months (±2 weeks).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Dose Limiting Toxicities (DLTs)

    DLT was defined as occurrence of any of the following toxicities that are possibly, probably or definitely related to therapy.

    Hematologic:

    1. Grade 4 hematologic toxicity.
    2. Febrile neutropenia, defined as absolute neutrophil count (ANC) < 1000/mm^3 with a single temperature of >38.3° C (101° F) or a sustained temperature of >38° C (100.4° F) for more than 1 hour.
    3. Grade 3 thrombocytopenia lasting >72 hours.
    4. Grade 4 thrombocytopenia.

    Non-Hematologic:

    1. ≥Grade 3 non-hematologic toxicity
    2. Grade 3 non hematologic laboratory values.
    3. Listeremia: positive blood cultures along with persistent (for 72 hours post dose) symptoms consistent with listeremia (e.g., fever and muscle aches, often preceded by diarrhea or other gastrointestinal symptoms).
    4. ≥Grade 3 flu-like symptoms or cytokine release symptoms that persist for >24 hours after study treatment administration despite symptomatic treatment.

    Measured: Up to 28 days in Cycle 1 (12 weeks cycle)

  2. Listeria Monocytogenes Surveillance

    Number of participants with delayed listeria infection was reported.

    Measured: Up to 120 days post dose

  3. Number of Participants With Adverse Events

    Adverse event (AE): any untoward medical occurrence in a participant administered a study treatment \& which did not necessarily have to have a causal relationship with the study treatment. An AE is, any unfavorable \& unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that was temporally associated with the use of study treatment. AE with onset on or after the date of first administration of the study treatment until the end of the Listeria Monocytogenes (Lm) surveillance period.

    Measured: From first dose up to 2.3 years

Secondary outcomes (6)

  1. Objective Response Rate (ORR) as Per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1

    ORR as per RECIST 1.1 was defined as the percentage of participants who achieved complete response (CR) or partial response (PR). CR was defined as disappearance of all lesions. PR was defined as ≥30% decrease in the sum of the longest diameter of all target lesions compared with baseline, in absence of new lesions or unequivocal progression of non-target lesions.

    Measured: From first dose until end of treatment (Maximum duration: 1.5 years)

  2. Duration of Tumor Response as Per RECIST 1.1

    Duration of response as per RECIST 1.1 was defined as the time interval from CR or PR to disease progression or death. CR was defined as disappearance of all lesions. PR was defined as ≥30% decrease in the sum of the longest diameter of all target lesions compared with baseline, in absence of new lesions or unequivocal progression of non-target lesions. Progressive disease (PD) was defined as at least 20% increase in sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. The appearance of one or more new lesions is also considered progression .Kaplan-Meier method was used to estimate median and 95% confidence interval (CI).

    Measured: From first objective response to disease progression or death (Maximum duration: 1.5 years)

  3. Progression Free Survival (PFS) as Per RECIST 1.1

    PFS as per RECIST 1.1 was defined as the time interval from study enrollment to disease progression or death. Participants who were alive with no disease progression were censored at the date of the last tumor assessment. PD was defined as at least 20% increase in sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. The appearance of one or more new lesions is also considered progression.The Kaplan-Meier method was used to estimate median and 95% CI.

    Measured: From study enrollment to disease progression or death (Maximum duration: 1.5 years)

  4. ORR as Per Immune-related Response Evaluation Criteria in Solid Tumors (irRECIST)

    ORR as per irRECIST was defined as the percent of participants who achieved immune response complete response (irCR) or immune response partial response (irPR). irCR was defined as disappearance of all lesions. irPR was defined as ≥30% decrease in tumor burden compared with baseline.

    Measured: From first dose until end of treatment (Maximum duration was 1.5 years)

  5. Duration of Tumor Response as Per irRECIST

    Duration of response as per irRECIST 1.1 was defined as the time interval from irCR or irPR to disease progression or death. irCR was defined as disappearance of all lesions. irPR was defined as ≥30% decrease in tumor burden compared with baseline. Immune response progressive disease (irPD) was defined as at least 20% increase in tumor burden compared with nadir (at any single time point). The Kaplan-Meier method was used to estimate median and 95% CI.

    Measured: From first objective response to disease progression or death (Maximum duration: 1.5 years)

  6. PFS as Per irRECIST

    PFS as per irRECIST 1.1 was defined as the time interval from study enrollment to disease progression or death. Participants who were alive with no disease progression were censored at the date of the last tumor assessment. irPD was defined as at least 20% increase in tumor burden compared with nadir (at any single time point). The Kaplan-Meier method was used to estimate median and 95% CI.

    Measured: From study enrollment to disease progression or death (Maximum duration: 1.5 years)
