Trial purpose
Genes contain genetic code which tell the body which proteins to make. Many types of cancer are caused by changes, or mutations, in a gene called KRAS. Researchers are looking for ways to stop the actions of abnormal proteins made from the mutated KRAS gene. The so-called G12D mutation in the KRAS gene is common in people with some solid tumors.
ASP3082 is a potential new treatment for solid tumors in people who have the G12D mutation in their KRAS gene. Before ASP3082 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. This information will help find a suitable dose and to check for potential medical problems from the treatment.
Who May Participate
People in this study will be adults with locally advanced, unresectable or metastatic solid tumors with the G12D mutation in their KRAS gene. Locally advanced means the cancer has spread to nearby tissue. Unresectable means the cancer cannot be removed by surgery. Metastatic means the cancer has spread to other parts of the body. The key reasons people cannot take part are if they have symptomatic or untreated cancers in the brain or nervous system, their cancer has spread to the thin tissue that covers the brain and spinal cord (leptomeningeal disease), or they have recently had other active cancers that required treatment.
For ASP3082 combination therapy with Nab-P+GEM or FOLFIRINOX: Participant must have mPDAC that has not been previously treated with chemotherapy. If a participant received (neo)adjuvant therapy, tumor recurrence or disease progression must have occurred at least 6 months after completing the last dose of the (neo)adjuvant therapy.
What to expect
This is an open-label study. This means that people in this study and clinic staff will know that they will receive ASP3082. This study will be in 2 parts.
In Part 1, different small groups of people will receive lower to higher doses of either: ASP3082 by itself or ASP3082 together with cetuximab. Any medical problems will be recorded at each dose. This is done to find suitable doses of ASP3082, by itself or together with cetuximab to use in Part 2 of the study. The first group will receive the lowest dose of ASP3082. A medical expert panel will check the results from this group and decide if the next group can receive a higher dose of ASP3082. The panel will do this for each group until all groups have received ASP3082 (by itself or together with cetuximab) or until suitable doses have been selected for Part 2.
In Part 2, other different small groups of people will receive: ASP3082 by itself, ASP3082 with cetuximab, ASP3082 with different types of chemotherapy, ASP3082 with pembrolizumab, or ASP3082 with chemotherapy and pembrolizumab. The most suitable doses of ASP3082 worked out from Part 1 will be used.
Study treatments will be given through a vein. This is called an infusion. Each treatment cycle is 21 or 28 days long. People will continue treatment until:
- they have medical problems from the treatment they can’t tolerate;
- their cancer gets worse;
- they start other cancer treatment;
- or they ask to stop treatment.
People will visit the clinic on certain days during their treatment, with extra visits during the first 2 cycles of treatment. At the clinic visits people will have health checks. Tumor samples will be taken at certain visits during treatment and when treatment has finished.
People will visit the clinic shortly after stopping treatment for a health check. After this, people will continue to have health checks every couple of months to check the condition of their cancer. They will do this until about 45 weeks after treatment stopped, or if their cancer is worse, they start other cancer treatment, or they ask to stop treatment.
試験の概要
The main aims (primary objectives)
- To check the safety of ASP3082 by itself and together with the other study treatments, and how well it is tolerated.
- To find a suitable dose of ASP3082 by itself and together with the other study treatments.
Other aims (secondary objectives)
- To check how ASP3082 is processed by the body (pharmacokinetics, or PK).
- To check how well ASP3082 controls tumors.
How the aims are carried out (endpoints)
- Recording medical problems that happen during the study after receiving ASP3082, whether they were caused by ASP3082 or not. This may include abnormal results from lab tests, medical examinations and electrocardiograms (ECGs).
- Checking if medical problems or abnormal lab test results that may be caused by ASP3082 are serious enough to stop increasing the dose.
- Checking blood levels of ASP3082 over time to learn how long it takes to get into the blood, spread through the body and be cleared by the body. Also checking if ASP3082 is broken down by the body.
- Using scans to check if tumors shrink or disappear over time, after treatment with ASP3082.
- Checking for changes in KRAS G12D protein levels on tissue samples.

よくあるご質問
一部の臨床試験は進行がんを対象としていますが、さまざまな病期の患者さんが参加できる臨床試験も数多くあります。それぞれの試験には一定の参加条件があります。たとえば特定の年齢層や腫瘍の種類の患者さんだけが参加できる場合もあります。
臨床試験によっては、現在受けている治療を続けたまま参加できる場合もあれば、一時的に中止しなければならない場合もあります。もし治験薬で効果がみられなかった場合でも、通常は元の治療を再開することができます。
がんの臨床試験でプラセボが使われるのは、特定のがんに利用できる治療が存在しない場合に限られ、治験薬とプラセボを比較するためにだけ使用されます。ただし、がんの臨床試験でプラセボが使われることはまれで、多くの場合は「標準治療」と呼ばれる最も有効とされる治療が提供されます。
担当医が、あなたに利用可能な臨床試験の機会をすべて把握していない場合があります。気になる臨床試験があった場合は、ぜひ担当医や他の医療提供者にご相談ください。あなたに合った臨床試験かどうかを、一緒に判断することができます。このウェブサイトで選択肢が見つからない場合は、公的な治験情報登録サイト(例: ClinicalTrials.gov )をご覧になり、現在募集中の臨床試験を探してみることをお勧めいたします。
