Participants will be assessed using ESAS, ENP and adhoc sociofamiliar questions just before entering their Phase I Clinical Trial (T0). Responses of this assessment will be discussed in a multidisciplinary committee comprised of a palliative physician, a clinical psychologist, a social worker, an oncologist, an hematologist and the Phase 1 Unit referent nurse. According to the patient responses, the committee will decide which needs will be addressed and this will be cited to the corresponding professional (palliative, psychologist and/or social worker) within the following 15 days. The same cycle (assessment - committee - attention) will take place a month after the T0 (T1), and during the following 2 other months (T2 and T3).

Participants will be assessed using ESAS, ENP and adhoc sociofamiliar questions just before entering their Phase I Clinical Trial (T0), one month after (T1), two months after (T2) and three months after (T3).

The Early Intervention consists of the proper attention given to those patients who participate in a Phase I Clinical Trial. The attention will be based on a monthly assessment of their physical, psychological/emotional symptoms and, also their sociofamiliar needs. After having discussed patients's needs in a multidisciplinary committee, each professional (paliiative physician, clinical psychologist and/or wocial orker) will proportionate them the required attention in order to increase their quality of life.

Physical and psychosocial symptoms will be assessed using the ESAS (Edmonton Symptoms Assessment Scale). This scale assesses, using a 10-point Likert scale, the intensity of the following symptoms: pain, fatigue, nausea, depression, anxiety, drowsiness, shortness of breath, appetite, sleep, and feeling of wellbeing.

Psychosocial symptoms will be assessed using the ENP-E (Psychosocial and Spiritual Needs Evaluation Scale). This scale assesses, using a 5-point Likert Scale the following dimensions: mood, sadness, feeling nervous, bearability of the situation, sharing the illness with the family, need for more information about the disease, feeling cared for and supported by family and friends, satisfaction with life, feeling in peace, meaning in life, presence of values and beliefs to cope with the situation, level of well-being. Also, the tool explores economic, family, emotional, spiritual and physical concerns, together to signs of emotional distress.

Sociofamiliar needs of patients will be assessed using the following ad-hoc questions: In the family unit, are there minors, disabled people or other people who require attention? (e.g.: elderly people with chronic disease).

Is your habitual residence at such a geographical distance that it entails special needs? Is there a caregiver available? In addition to the disease, do you have any other health problem that limits your day-to-day life? Do you feel capable of sharing the process of the illness with your family? Would you need professional guidance/advice for aspects related to employment procedures, resources, benefits, housing needs, financial aid?
