Study Endpoints

Primary Endpoints

Dose Finding will be calculated based upon toxicity screening and dose modification guidelines within protocol.
AEs will be assessed at each cycle visit, discontinuation treatment visit, and 30 days post last day of study treatment
Objective Response Rate will be assessed by the RECIST guideline documented in the European Journal of Cancer, 2009.
Tumor evaluation via RECIST guidelines will be done on screening visit, day 22 of every other cycle, and treatment discontinuation visit
Overall Survival
From date of randomization until death, withdrawal of consent or the end of the study. The end of the study was defined as the date all AZD6244 patients had been followed for a minimum of 12 months, or the date of final analysis, whichever was later

Following progression survival data was collected until documentation of death, withdrawal of consent, loss to follow-up or the final data cut-off, whichever occurred first.

Progression event count
assessed after each visit
Assess tumor growth
assessed every 12 weeks
Median time to death (TTD)
Data cut off for this analysis was 5th April 2008.

The TTD (days) was calculated as the interval from date of randomisation to date of patient death (from any cause). Patients who had not died at the time of the final analysis were censored at the last date the patient was known to be alive. Median TTD in days is presented here.

Frequently asked questions about AZD6244

What is AZD6244 used for?

AZD6244 is an investigational small molecule being studied in oncology for advanced solid malignancies and specific cancers including non-small cell lung cancer, pancreatic cancer, melanoma, and metastatic colorectal cancer. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

What does AZD6244 target?

AZD6244 is a small molecule that targets the MEK pathway, which is involved in cell growth and proliferation. By inhibiting this pathway, the drug aims to slow or stop the growth of cancer cells. This mechanism is being evaluated in clinical trials for various solid tumors.

Who makes AZD6244?

AZD6244 is being developed by AstraZeneca PLC, a biopharmaceutical company listed on the stock exchange under the ticker symbol AZN. The company is conducting clinical trials to evaluate the safety and efficacy of this investigational drug in patients with advanced cancers.

What phase is AZD6244 in?

AZD6244 is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not yet received approval from regulatory agencies such as the FDA. The drug is being studied in early-stage trials to assess its safety, tolerability, and pharmacokinetics in patients with advanced solid tumors.

What clinical trials is AZD6244 in?

AZD6244 has been studied in several clinical trials, including NCT00463814, a Phase 1 study in advanced solid malignancies, and NCT00600496, a Phase 1 trial in various cancers. A Phase 2 trial, NCT00890825, evaluated AZD6244 with docetaxel in KRAS mutation positive NSCLC patients. Another Phase 1 trial, NCT01605916, was conducted in Japanese patients.

Is AZD6244 the same as ARRY-142886?

Yes, AZD6244 is also known as ARRY-142886. Clinical trial records refer to the drug by both names, such as in the study titled 'AZD6244 (ARRY-142886) Solid Oral Dosage Formulation in Participants With Advanced Solid Malignancies.' This alternative name is used interchangeably in research documentation.
