Safety Extension Trial of Inhaled Molgramostim in Autoimmune Pulmonary Alveolar Proteinosis

A Phase 3 interventional study of Molgramostim in Autoimmune Pulmonary Alveolar Proteinosis, sponsored by Savara Inc.. Terminated at 13 sites in 10 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-07-03.

Sponsored by Savara Inc. · Phase 3, Interventional, and Treatment

Why this study was terminated
SAV006-03 was initiated before the evaluation of the IMPALA study (NCT02702180) results. Considering these results and authority advice there would not be adequate efficacy and safety data from SAV006-03 and the study was terminated.

Study summary

SAV006-03 is an open-label extension study for participants who had completed the IMPALA study.

At the baseline visit, eligible participants may continue or re-start treatment with 300 µg inhaled molgramostim (recombinant human Granulocyte-Macrophage Colony Stimulating Factor; GM-CSF) administered intermittently in cycles of seven days molgramostim, administered once daily, and seven days off treatment.

Participants will be treated with inhaled molgramostim for up to 36 months.

During the trial, whole lung lavage will be applied as rescue therapy.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Completer of the IMPALA trial.
  • Females who have been post menopausal for >1 year, or females of who are not pregnant or lactating and are using acceptable methods.
  • Males agreeing to use using acceptable contraceptive methods.
  • Willing and able to provide signed .

Exclusion criteria

Exclusion Criteria:

  • Treatment with GM-CSF products other than molgramostim nebuliser solution within three months of Baseline.
  • Treatment with any medicinal product other than inhaled molgramostim within four weeks of Baseline.
  • History of allergic reactions to GM-CSF.
  • Connective tissue disease, inflammatory bowel disease or other disorder requiring treatment associated with significant , e.g. more than 10 mg/day systemic prednisolone.
  • Previous experience of severe and unexplained side effects during aerosol delivery of any kind of medicinal product.
  • History of, or present, myeloproliferative disease or leukaemia.
  • Apparent pre-existing concurrent pulmonary fibrosis.
  • Any other serious medical condition which in the opinion of the investigator would make the subject unsuitable for the trial.
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

What researchers measure

Primary outcomes

  1. Number of Treatment-emergent Adverse Events (TEAEs)

    The primary objective of this trial was safety assessed by adverse event (AE) reporting. Definitions and reporting procedures for AEs were done according to current regulatory standards. AEs were collected by the investigator by a non-leading question and by reporting events directly observed or spontaneously volunteered by participants. Participants were also encouraged to contact the clinic in between visits if they experienced AEs or had any concerns. Treatment-emergent was defined as events occurring on study drug and up to 7 days after last dose of study drug.

    Time frame: 139 weeks

  2. Number of Serious TEAEs

    Serious TEAEs were defined as any untoward medicinal occurrence or effect that at any dose: * Results in death * Is life-threatening * Requires hospitalisation or prolongation of existing hospitalisation * Results in persistent or significant disability or incapacity * Is a congenital abnormality or birth defect * May jeopardise the participant or may require medical intervention to prevent one or more of the outcomes listed above (Important Medical Events).

    Time frame: 139 weeks

  3. Number of Treatment-emergent Adverse Drug Reactions (ADRs)

    All AEs were assessed by the investigator for causality (unlikely, possible, probable, not applicable) according to current regulatory standards. AEs which had a 'possible' or 'probable' causality were classified as ADRs.

    Time frame: 139 weeks

  4. Number of TEAEs Leading to Treatment Discontinuation

    Time frame: 139 weeks

Results

Posted Jul 3, 2024
Limitations and caveats
No hypothesis/statistical testing was planned for any of the endpoints of this study but only descriptive statistics were to be used. Efficacy endpoints were secondary endpoints. Due to early study termination, only limited efficacy data were available for evaluation and in general, no firm conclusion based on efficacy data are applicable. No deaths occurred during the study but 1 participant died due to COVID-19 24 days after last dose, i.e. outside the definition of 'treatment-emergent'.

Participant flow

SAV006-03 was an open-label extension trial for participants who had completed the IMPALA study. Among the 30 clinical sites enrolling participants in IMPALA, 13 sites participated in SAV006-03. First participant was enrolled on 16 April 2018 and last participant completed the study on 14 January 2021.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 3, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
