Brief Summary:

Background:

Anetumab ravtansine is a new drug. It kills cancer cells that carry mesothelin. That is a protein on the surface of tumor cells in many types of tumors, including most lung cancers. Researchers want to find a safe dose for the study drug for lung cancer. They want to see if it can shrink tumors in mesothelin-positive lung cancer.

Objectives:

To test the safety and effectiveness of anetumab ravtansine for lung cancer.

Eligibility:

Adults 18 years and older who have lung cancer that has gotten worse on other therapy

Design:

Participants will be screened with:

Medical history

Physical exam

Tumor tissue sample. This can be from a previous procedure.

Blood and urine tests

Heart tests

Scans. For one scan, a small amount of radioactive substance is injected into the blood.

Eye exam

The study will have 21-day cycles.

On day 1 of each cycle, participants will get the study drug through a tube inserted in a vein.

Participants will repeat a heart test in cycles 1 and 2.

They will have blood tests weekly in cycle 1, twice in all other cycles.

They will have scans every 6 weeks for the first 6 months, every 9 weeks until the end of year 2, then every 12 weeks.

Participants will have samples of tumor tissue taken twice.

About 30 days after stopping the study drug, participants will have a follow-up visit. This will include medical history, physical exam, blood and pregnancy tests, and heart and eye tests.

Some will be called a few times a year to discuss their health and treatment.

Primary Outcome Measures :
  1. Recommended Phase 2 Dose (RP2D) [ Time Frame: 21 days after initiation of study therapy ]
    The highest dose tested at which no more than 1 dose limiting toxicity occurs. A dose limiting toxicity is defined as any treatment emergent adverse event (TEAE) (i.e., absolute neutrophil count <500/mm^3 for ≥7 days) occurring during Cycle 1 and regarded to be at least possibly related to anetumab ravtansine.

  2. Proportion of Subjects Who Experienced a Partial or Complete Response [ Time Frame: 6 weeks ]
    Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). A complete response is disappearance of all target lesions. A partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters.


Secondary Outcome Measures :
  1. Progression Free Survival [ Time Frame: At Disease Progression, approximately 6 weeks. ]
    Length of time from start of treatment to time of progression or death, whichever occurs first. Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). Progression is 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. (Note: the appearance of one or more new lesions is also considered progressions).

  2. Duration of Response [ Time Frame: At Disease Progression, approximately 6 weeks from start of treatment ]
    Duration of Response is from the time measurement criteria are met for Complete Response (CR) or Partial Response (PR). Length of time criteria are met for partial response or complete response (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented. Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). Progression is 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. (Note: the appearance of one or more new lesions is also considered progressions). A complete response is disappearance of all target lesions. A partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters.

  3. Overall Survival [ Time Frame: At Death, an average of 7.5 weeks after start of first cycle for both patients. ]
    Length of time from start of treatment to death from any cause.

  4. Number of Participants With Serious and Non-serious Adverse Events Assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0) [ Time Frame: Participants on the Safety run-in phase was assessed for approximately two months and 5 days. ]
    Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
