Summary

This very early trial aimed to see if adding high-dose vitamin C to the immunotherapy drug durvalumab could boost the immune response against non-small cell lung cancer before surgery. It planned to enroll people with early-stage lung cancer, but was terminated after only one participant. Because it stopped so early, we cannot draw any meaningful conclusions about safety or effectiveness.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
high-dose vitamin C (pharmacological ascorbate) and durvalumab (an immunotherapy drug)
What this could lead to
If it had worked, this could have pointed toward a way to boost the immune system's attack on lung cancer before surgery.
What could go wrong
The trial was very early (Phase 1) and was terminated after enrolling just 1 person, so we have almost no data. It is unclear if the combination is safe or effective.

Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply: Women 1 year ago, had chemotherapy-induced menopause with last menses \>1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy). Exclusion Criteria: Patients should not enter the study if any of the following exclusion criteria are fulfilled: * Participation in another clinical study with an investigational product during the last 4 weeks prior to randomization * Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study * Prior systemic therapy for early-stage NSCLC that is under consideration for thisstudy. * Any unresolved toxicity NCI CTCAE Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, clinically non-significant labs values (e.g., lymphopenia), and the laboratory values defined in the inclusion criteria 1. Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician. 2. Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician. * Any concurrent chemotherapy, IP, biologic, or hormonal therapy for cancer treatment.Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable. * Radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the first dose of study drug * Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of IP. * History of allogenic organ transplantation. * Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease \[e.g., colitis or Crohn's disease\], diverticulitis \[with the exception of diverticulosis\], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome \[granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc\]).

Participants positive for HCV antibody are eligible only if polymerase chain reaction is negative for HCV RNA * Known to have tested positive for human immunodeficiency virus (HIV) (positive HIV 1/2 antibodies) or active tuberculosis infection (clinical evaluation that may include clinical history, physical examination and radiographic findings, or tuberculosis testing in line with local practice). * Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. The following are exceptions to this criterion: 1. Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection) 2.
