Brief Summary:
Protocol PEN-221-001 is an open-label, multicenter Phase 1/2a study evaluating PEN-221 in patients with SSTR2 expressing advanced gastroenteropancreatic (GEP) or lung or thymus or other neuroendocrine tumors or small cell lung cancer or large cell neuroendocrine carcinoma of the lung.

Condition or disease Intervention/treatment Phase
Neuroendocrine Tumors Carcinoma, Small Cell Lung Neuroendocrine Carcinoma Drug: PEN-221 Phase 1 Phase 2

Detailed Description:

Protocol PEN-221-001 will first enroll patients into a dose escalation phase, where a Bayesian logistic regression model, guided by the escalation with overdose control principle and overseen by a safety review committee, will be used to make dose recommendations and estimate the maximum tolerated dose (MTD).

Once the MTD has been confirmed, remaining patients will be enrolled into a full expansion phase to assess PEN-221 efficacy in patients with gastrointestinal mid-gut neuroendocrine tumors or pancreatic neuroendocrine tumors or small cell lung cancer.


Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 90 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1/2a, Open-label Multicenter Study to Assess the Safety, Tolerability, Pharmacokinetics, and Preliminary Antitumor Activity of PEN-221 in Patients With Somatostatin Receptor 2 Expressing Advanced Cancers, Including Gastroenteropancreatic or Lung or Thymus or Other Neuroendocrine Tumors or Small Cell Lung Cancer or Large Cell Neuroendocrine Carcinoma of the Lung
Actual Study Start Date : December 8, 2016
Estimated Primary Completion Date : June 2019
Estimated Study Completion Date : December 2019


Arm Intervention/treatment
Experimental: PEN-221
intravenous administration of PEN-221
Drug: PEN-221
Administration of PEN-221 once every three weeks




Primary Outcome Measures :
  1. High Grade (>=Grade 3) Treatment related adverse events [ Time Frame: From date of first treatment/trial entry until 28 days after last treatment, estimated 12 months ]
    Treatment related adverse events are assessed using CTCAE criteria.

  2. Phase 2a: Efficacy of PEN-221 as determined by RECIST 1.1 [ Time Frame: Baseline, every 6 weeks (SCLC) or every 9 weeks (NET) up to time of disease progression or death (estimated 36 months) ]
    Objective response rate (ORR) defined as the percentage of participants with best overall response of either complete response (CR) or partial response (PR) according to RECIST 1.1

  3. Phase 2a: Duration of response (DOR) [ Time Frame: estimated 36 months ]
    Duration of response (DOR) defined as the time between the date of first response (CR or PR) to the date of the first documented tumor progression (per RECIST 1.1) or death due to any cause, whichever comes first


Secondary Outcome Measures :
  1. Maximum concentration of PEN-221 and its metabolites (Cmax) [ Time Frame: up to 2 months ]
    Maximum concentration of PEN-221 concentration in circulating blood

  2. Area under the curve (AUC) of PEN-221 and its metabolites [ Time Frame: up to 2 months ]
    Area under PEN-221 concentration v time curve in circulating blood

  3. Half-life (t1/2) of PEN-221 and its metabolites [ Time Frame: up to 2 months ]
    Half life of PEN-221 concentration in circulating blood

  4. Radiographic progression free survival [ Time Frame: From date of first treatment/trial entry until the date of first documented progression or date of death from any cause, whichever came first, assessed up to (estimated) 36 months ]
    Radiographic progression free survival based on assessment of tumor size by CT or MRI (RECIST 1.1)

  5. Overall survival [ Time Frame: From date of first treatment/trial entry until the date of date of death from any cause, assessed up to (estimated) 36 months ]
    Time to death

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

Inclusion Criteria:

  • M/F at least 18 years old
  • Performance status 0 or 1
  • Adequate bone marrow, liver, and kidney function within 2 weeks prior to first dose
  • Serum potassium, calcium, magnesium, phosphorus within normal limits (may be supplemented)
  • Adequate birth control
  • Somatostatin receptor 2 positive tumor as assessed at pre-screening or within 180 d of first drug dose using indium SPECT or gallium PET

Patients in Phase 1 must have a histologically or cytologically-confirmed solid tumor in 1 of the following categories:

  • Advanced small cell lung cancer (SCLC) or large cell neuroendocrine carcinoma (LCNEC) of lung progressed after at least 1 line of anticancer chemotherapy
  • Advanced low or intermediate grade gastroenteropancreatic or lung or thymus neuroendocrine tumor (NET), or NET of unknown primary, progressed after at least 1 line of anticancer therapy (unless no standard treatments available or such treatments are deemed not appropriate)
  • Advanced paraganglioma, pheochromocytoma, medullary thyroid carcinoma, Merkel cell carcinoma, or high grade extrapulmonary neuroendocrine carcinoma having progressed after 1 or more lines of anticancer chemotherapy (unless no standard treatments available or such treatments are deemed not appropriate)

For patients enrolling once escalation is complete (Phase 2a), disease must be measurable per RECIST 1.1 criteria with last imaging performed within 28 days prior to first drug dose

In addition to the criterion listed above, Patients in Phase 2a must have a histologically- or cytologically-confirmed, advanced or metastatic solid tumor, in 1 of the following categories: disease history specified in one of the criteria listed below:

  • Well differentiated, low or intermediate grade, gastrointestinal mid-gut (arising from the lower jejunum, ileum, appendix, cecum, and proximal colon) NET with documented disease progression within 6 months prior to start of study treatment and evidence of radiographic disease progression based on scans performed not more than 15 months apart. Patients may have received 1 or more prior lines of anticancer therapy, such as somatostatin analogues, targeted agents, or liver-directed intra-arterial therapy, but are NOT eligible if they have received prior systemic cytotoxic chemotherapy or peptide receptor radionuclide therapy (PRRT).
